Nearly every listing states a read figure and far fewer state a write figure

The best USB flash drives for 2026

A flash drive is judged on two figures that makers publish very unevenly. Nearly every listing states a read speed; far fewer state a write speed, and the write figure is the one that decides how long you stand at the machine while a folder copies onto it. Where only one number appears, take it as the read figure. Both depend on the USB generation, published with a rate in gigabits per second, and on the memory inside, which is why two drives quoting the same generation can be a long way apart in practice. The connector is the second decision: Type-A still fits most machines, Type-C fits recent laptops and phones, and dual-connector drives carry both on one body, which is convenient and makes the drive longer. Capacity is quoted in decimal gigabytes, so a drive shows a smaller figure once an operating system counts in units of 1024 and once a file system takes its share; the figure published here is the maker's, in the maker's unit. Then the body, which is where these are actually lost or broken: a retractable or capped design, whether the cap is captive, a metal or plastic shell, a keyring loop, and any stated water or dust rating. Warranty periods vary widely across this family and are a commercial term rather than a statement about the memory. Note too that a wide drive left in permanently blocks the sockets beside it. We compare capacity, USB generation and stated link rate, connector type, stated read and write figures, body design, keyring provision, stated ingress rating and warranty length.

The ones worth keeping in the drawer

1. 

   Hama C-Laeta FlashPen, 128 GB, USB-C 3.2 Gen 1 stated, metal housing

   A metal-bodied USB-C drive that names its generation twice over and never once says how fast it is: no rate in gigabits, no read figure, no write figure, on a page of five bullets.

   Capacity

   128 GB — stated in the title. The figure is the maker’s, printed in the maker’s decimal unit, and this page reports it in that unit rather than restating it in another

   USB generation

   USB 3.2 Gen 1 — stated in the title and again in the first bullet, which in the same sentence also names a USB 3.0/USB 3.1 (Gen. 1) connection. Whether that is a second plug on the same body or the same plug described from a second angle is not settled anywhere on the page

   Stated link rate

   Not published on the listing — neither a figure in gigabits per second nor one in megabytes per second appears in the title or in any of the five bullets. The generation is named and the rate that belongs beside it is left off

   Connector type

   Type-C — stated in the title, with the first bullet adding a USB 3.0/USB 3.1 (Gen. 1) connection alongside it. The third bullet gives the reversible plug as its own selling point: a USB-C plug goes in either way round

   Stated read figure

   Not published on the listing — in place of a number the second bullet offers direct recording and playback of films in Full HD, which describes a use rather than a rate

   Stated write figure

   Not published on the listing. Recording onto the drive is claimed in that same second bullet, and recording is a write operation described here without any figure attached to it

   Body design

   A metal housing — stated in the fourth bullet as high-grade and robust. No cap, no slider and no retractable mechanism is named, and no dimensions and no weight are given

   Keyring provision

   Not published on the listing — no loop, no eyelet and no lanyard hole is named in any bullet

   Stated ingress rating

   Not published on the listing — no IP code, no water figure and no dust figure appears. The robustness claimed in the fourth bullet is a claim about the shell, not a rating

   Warranty length

   Not published on the listing — the fifth bullet gives the box contents as one FlashPen C-Laeta and the page stops there

   Amazon reference

   B07QT6GZ6W (same reference on 6 Amazon marketplaces)

   EAN

   4047443414878

   • Names the generation behind both connections it describes, rather than printing one bare USB number
   • A metal shell, on the least expensive drive here
   • No read figure and no write figure at all, which is the pair of numbers this shelf is read on

   Best for: A phone or a recent laptop where the socket is Type-C, when what matters is that the drive fits at all rather than how long it takes to fill.

2. 

   SanDisk Ultra Flair, 128 GB, USB 3.0, USB-A, 150 MB/s read stated, metal body

   The drive on this shelf that labels its own number: 150 MB/s, and the word “read” beside it in the title and again in the contents line, with nothing at all said about writing.

   Capacity

   128 GB — stated in the title and again in the fifth bullet. The maker’s decimal figure, reported here in the maker’s unit

   USB generation

   USB 3.0 — stated in the second bullet and again in the fifth, which names the product as a SanDisk Ultra Flair USB 3.0 flash drive. No USB 3.1 or 3.2 designation appears

   Stated link rate

   Not published on the listing as a class rate — no figure in gigabits per second is given anywhere. The only rate on the page is 150 MB/s, which the listing attaches to the drive rather than to the port

   Connector type

   Type-A — stated in the title, which calls it a USB-A drive. No second connector is named and no Type-C variant is described

   Stated read figure

   150 MB/s — stated in the title as up to 150 MB/s for reading, and again in the fifth bullet as 150 MB/s read. The second bullet attaches the same number to USB 3.0 performance without naming a direction, so two of the three mentions say plainly which operation it describes

   Stated write figure

   Not published on the listing — no writing figure appears in any of the five bullets. The third bullet claims a feature film transferred onto the drive in under 30 seconds, which describes a write operation as a duration rather than as a rate, and names no file size to go with it

   Body design

   A metal casing described as robust and shock-resistant in the third bullet, with a slim design named as the reason it looks the way it does. No cap and no retracting mechanism is mentioned, and no dimensions or weight are given

   Keyring provision

   Not published on the listing — no loop and no eyelet is named. The photograph is the only source, and this page does not read specifications off photographs

   Stated ingress rating

   Not published on the listing — the shock resistance claimed in the third bullet is not a water or dust rating, and no IP code appears

   Warranty length

   Not published on the listing — what the first bullet does publish is a one-year subscription to RescuePRO recovery software, which is a licence period and not a warranty on the drive

   Amazon reference

   B015CH1PJU (same reference on 6 Amazon marketplaces)

   EAN

   0619659136710

   • Puts the word “read” beside its own figure, which four listings on this shelf never do
   • Ships with a named recovery utility and states how long the subscription runs
   • No write figure at all, on a drive whose read figure is the highest number printed here

   Best for: A machine with Type-A sockets where files come off the drive more often than they go on to it — a media library carried between computers rather than a working folder.

3. 

   Kingston DataTraveler Exodia, 128 GB, USB 3.2 Gen 1 stated, cap and keyring loop

   The shortest listing on this shelf by a distance — three bullets, every one of them about the shell — with a generation in the title and not a single figure to put against it.

   Capacity

   128 GB — stated in the title and carried in the part number itself, DTX/128GB. A decimal figure from the maker, reported here as printed

   USB generation

   USB 3.2 Gen 1 — stated in the title as USB-Stick 3.2 Gen 1. No bullet repeats it, and no backward-compatibility note appears

   Stated link rate

   Not published on the listing — no gigabits per second and no megabytes per second appear in the title or in the three bullets. The generation stands alone

   Connector type

   Not published on the listing — the second bullet names a protective cap for the USB plug without saying whether that plug is Type-A or Type-C, and the title names neither. It is the only drive in this hub whose connector shape is left unstated

   Stated read figure

   Not published on the listing — no reading figure appears in any form

   Stated write figure

   Not published on the listing — no writing figure appears either. The page carries three bullets and none of them is about speed

   Body design

   A capped body — stated in the second bullet, which names a practical protective cap for the plug. The third bullet adds that several colours are offered and that which colour you get depends on the capacity ordered

   Keyring provision

   A large eyelet for attaching to a keyring — stated in the first bullet, which is the opening claim of the whole listing. It is the only keyring provision published on this shelf

   Stated ingress rating

   Not published on the listing — no IP code and no water or dust figure appears. The cap named in the second bullet is offered as protection for the plug, which is not a rating

   Warranty length

   Not published on the listing — no period is given anywhere on the page

   Amazon reference

   B08JD4TBM3 (same reference on 6 Amazon marketplaces)

   EAN

   0740617309843

   • The only drive on this shelf that publishes a keyring loop, and it leads with it
   • A cap for the plug, named as a feature rather than left to the photograph
   • No speed figure of any kind, in either direction

   Best for: A drive that lives on a keyring and gets lost if it does not, where the loop and the cap are the specification that actually decides the purchase.

4. 

   RAOYI 2-in-1 OTG drive, 128 GB, USB 3.0 and Type-C, ≥ 80 MB/s read and ≥ 30 MB/s write stated

   The one listing in this hub that writes its numbers as minimums instead of maximums — at least 80 megabytes a second reading, at least 30 writing — on a body carrying a Type-A plug and a Type-C plug at once.

   Capacity

   128 GB — stated in the title three times over and in the fourth bullet. The maker’s decimal figure, reported as printed

   USB generation

   USB 3.0 — stated in the title and in the first and fourth bullets. No USB 3.1 or 3.2 designation appears, and the Type-C side is described by its connector rather than by a generation of its own

   Stated link rate

   Not published on the listing as a class rate — no figure in gigabits per second is given. The two figures on the page are megabytes per second and belong to the drive rather than to the link

   Stated read figure

   At least 80 MB/s — the second bullet gives a reading speed of ≥ 80 MB/s. The greater-or-equal sign is the maker’s own, and it makes this a floor rather than the ceiling that “up to” describes on every other listing in this hub

   Stated write figure

   At least 30 MB/s — the second bullet gives a writing speed of ≥ 30 MB/s in the same sentence as the reading figure, and in the same form. It is one of only three write figures published on this shelf

   Connector type

   Type-A and Type-C on one body — stated in the title as a 2-in-1 dual drive and again in the first bullet, which names the USB 3.0 and Type-C interfaces and gives transfer between a phone and a computer as the purpose

   Body design

   Not published on the listing — no material is named for the shell, no cap or slider is described, and no dimensions and no weight are given. The fourth bullet names the OTG function as the reason for the shape without describing the shape

   Keyring provision

   Not published on the listing — no loop, eyelet or lanyard is named

   Stated ingress rating

   Not published on the listing — no IP code and no water or dust figure appears anywhere

   Warranty length

   12 months — stated in the fifth bullet, alongside lifelong technical support and an invitation to use the store page for questions

   Amazon reference

   B07H3QQNY3 (same reference on 5 Amazon marketplaces)

   EAN

   0763230622229

   • Publishes a reading figure and a writing figure, which only three of the seven drives here do
   • Writes both as minimums, so the number is a promise rather than a best case
   • No material named for the body, and no dimensions or weight either

   Best for: Moving photographs off a phone and onto a computer without a cloud account in the middle, where both ends need a different plug and neither should need an adapter.

5. 

   Amazon Basics 128 GB, USB 3.1 stated, telescopic body, 130 read and 30 write stated, 115 GB usable published

   The only drive in this hub whose maker prints the usable figure alongside the label figure — and the only one that prints its headline number in two different units within a single page.

   Capacity

   128 GB — stated in the title, with the fifth bullet adding that the available storage is more than 115 GB and naming differing measurement standards as the reason the two figures differ. Both numbers are the maker’s own and both are reported here as printed; neither is calculated by this page

   USB generation

   USB 3.1 — stated in the title. The first bullet is more specific: a USB 3.1 Gen 1 or USB 3.0 port is required on the host machine to reach the stated read and write speeds, with backward compatibility to USB 2.0 hosts at a lower rate

   Stated link rate

   Not published on the listing — no class rate in gigabits per second appears. The first bullet claims the drive is 15 times faster than USB 2.0 drives, which is a comparison rather than a rate

   Stated read figure

   130, printed in two units on the same page. The title gives up to 130 Mbit/s; the first bullet gives up to 130 MB/s. The two units differ by a factor of eight and the listing never reconciles them, so both are reported here exactly as written and neither is converted

   Stated write figure

   Up to 30 MB/s — stated in the first bullet, in the same sentence as the reading figure. The bullet attributes both to internal tests under controlled conditions and adds that actual speeds vary with the device, the transfer size, the file types and other factors

   Connector type

   Not published on the listing as a plug shape — the first bullet names the host ports required, USB 3.1 Gen 1 or USB 3.0, which is a class and not a connector, and no Type-A or Type-C designation appears in the title or the bullets

   Body design

   A telescopic design — stated in the third bullet, which names the retracting body as what protects the drive from damage when it is not in use. There is no separate cap to lose. No material, no dimensions and no weight are given

   Keyring provision

   Not published on the listing — no loop or eyelet is named in any of the five bullets

   Stated ingress rating

   Not published on the listing — no IP code and no water or dust figure appears

   Warranty length

   Not published on the listing — no period is stated. The fifth bullet closes on a note about checking the storage requirements of devices such as games consoles before use

   Amazon reference

   B0B6148YKN (same reference on 6 Amazon marketplaces)

   EAN

   0840095889711

   • Publishes the available capacity itself, at more than 115 GB, which no other listing on this shelf does
   • States the host port needed to reach its own figures, rather than printing a bare number
   • The same headline number appears as Mbit/s in the title and MB/s in the first bullet

   Best for: A first drive for somebody who has been caught out by a capacity that displayed smaller than the box promised, since this is the listing that explains the difference on the page rather than after the sale.

6. 

   Lexar JumpDrive D40E dual drive, 128 GB, Type-A and Type-C, 100 MB/s transfer stated, 26 g

   The most thoroughly measured drive on this shelf — millimetres, grams, an operating temperature range and the definition of its own megabyte — and the only one that never names a USB generation at all.

   Capacity

   128 GB — stated in the title. The second bullet adds the maker’s own definition of the unit, 1 MB = 1,000,000 bytes, which is the decimal count the label figure rests on

   USB generation

   Not published on the listing — no 3.0, no 3.1 and no 3.2 appears in the title or in any of the five bullets. The first bullet names USB Type-A and Type-C connectors and the OTG role, which are shapes and a function rather than a generation. It is the only drive in this hub with no generation stated

   Stated link rate

   Not published on the listing — no class rate in gigabits per second is given, which follows from the generation being absent

   Stated read figure

   Not published as a read figure. The second bullet gives transfer speeds of up to 100 MB/s without naming a direction, and adds that performance varies with the host device, the interface and the conditions of use. Where a maker publishes one undirected figure it is normally the reading one, and this page reports the figure rather than assigning it

   Stated write figure

   Not published on the listing — no separate writing figure appears anywhere, and the single 100 MB/s figure is not broken down by direction

   Connector type

   Type-A and Type-C on one body — stated in the first bullet as a 2-in-1 OTG design in a slim, portable form. The title names the Type-C side and the colour, titanium grey

   Body design

   A metal housing measuring 70.4 × 16.9 × 11.7 mm and weighing 26 g — stated in the third bullet, which also gives an operating temperature range of 0 °C to 50 °C (32 °F to 122 °F). The fourth names a cap that rotates through 360° so it swaps between the connectors without ever being removed and lost

   Keyring provision

   Not published on the listing — no loop, eyelet or lanyard is named in any bullet

   Stated ingress rating

   Not published on the listing — no IP code and no water or dust figure appears. The temperature range in the third bullet describes operating conditions and is not an ingress rating

   Warranty length

   Three years, limited — stated in the fifth bullet alongside security software offering 256-bit AES encryption. It is the longest warranty published on this shelf

   Amazon reference

   B0FMF5R4Q3 (same reference on 6 Amazon marketplaces)

   EAN

   0843367143672

   • Publishes dimensions to a tenth of a millimetre and a weight, which four listings here never do
   • The rotating cap covers whichever plug is not in use and cannot be mislaid
   • No USB generation anywhere, so the class of link is unstated

   Best for: Carrying between a laptop and a phone in a coat pocket, where the cap that cannot be lost and the 26 g body matter more than a headline rate.

   Intenso Speed Line twin pack, two drives of 128 GB, USB 3.2 Gen 1x1 stated, 70 MB/s, 8 g each

   A twin pack rather than a single drive, with a plastic body weighed to the gram and measured to the millimetre, and one transfer figure that never says which direction it belongs to.

   Capacity

   128 GB per drive, supplied as two — stated in the title and in the third and fifth bullets, which describe the pack as two Intenso Speed Line drives of 128 GB. The listing publishes no combined figure and this page does not produce one by multiplication

   USB generation

   USB 3.2 Gen 1x1 — stated in the title and in the first and fifth bullets, which name it as Super Speed USB 3.2 Gen 1x1 and credit it for the transfer rate. It is the most precisely written generation on this shelf, since it names the lane arrangement as well as the class

   Stated link rate

   Not published on the listing — no class rate in gigabits per second appears alongside the generation. The only figure on the page is in megabytes per second

   Stated read figure

   Not published as a read figure — the first bullet gives transfer speeds of up to 70 MB/s and names no direction. Where a single undirected number is published on a flash drive it is normally the reading one, and this page reports the figure rather than assigning a direction the maker did not

   Stated write figure

   Not published on the listing — no separate writing figure appears in any of the five bullets, and the 70 MB/s figure is not broken down

   Connector type

   Not published on the listing — neither Type-A nor Type-C is named in the title or the bullets, and no cap or plug is described. The generation is stated and the shape of the plug carrying it is not

   Body design

   A plastic body described as robust — stated in the second bullet, which gives the weight as 8 g and the dimensions as 19 × 65 × 9 mm. No cap, no slider and no retracting mechanism is named

   Keyring provision

   Not published on the listing — no loop and no eyelet appears in any bullet

   Stated ingress rating

   Not published on the listing — no IP code and no water or dust figure is given. The robustness named in the second bullet is a claim about the plastic, not a rating

   Warranty length

   Not published on the listing — no period is stated anywhere on the page
