Five years, the longest term on this shelf

SanDisk Ultra 512 GB with encryption and the longest warranty on this shelf

Five years of warranty, the longest stated for a drive on this shelf, on the joint-largest capacity here — with password protection and a read figure of 130 MB/s against the 200 of the fastest.

SanDisk Ultra 512 GB with encryption and the longest warranty on this shelf

Five years of warranty, the longest stated for a drive on this shelf, on the joint-largest capacity here — with password protection and a read figure of 130 MB/s against the 200 of the fastest.

Capacity: 512 GB — stated in the title. It is the joint-largest capacity on this shelf, shared with the PNY Elite-X Fit. The description defines 1 GB as 1,000,000,000 bytes and notes that actual user storage is less, without giving the figure
USB generation: USB 3.0 — stated in the first bullet, which requires a USB 3.0 port for the quoted speed, with backwards compatibility to USB 2.0 in the second
Stated link rate: Not published on the listing — no figure in gigabits per second appears, only the generation name
Connector type: USB-A, designated in the title — which several of the seven listings on this shelf leave to be inferred. On a shelf where Type-C and dual-connector drives exist, printing it is the difference between a sure purchase and a return
Stated read figure: Up to 130 MB/s — stated in the first bullet with five qualifications: ten times a standard USB 2.0 drive at 4 MB/s, a USB 3.0 port required, based on internal testing, performance possibly lower depending on the host, and 1 MB defined as 1,000,000 bytes. It is the most carefully hedged speed claim on this shelf
Stated write figure: Not published on the listing — no writing rate appears in the title, the three bullets or the description. The single figure published is the read figure, as the first bullet states
Body design: Not described beyond the connector — the description calls it sleek and sturdy and names no cap, collar or retraction. At 8 g (0.3 oz) and 11 by 22 by 8 mm (0.31 in) it is the second-lightest drive on this shelf
Keyring provision: Not published on the listing — no loop, no clip and no lanyard hole is named anywhere
Stated ingress rating: Not published on the listing — no water rating, no dust rating and no IP figure appears
Warranty length: Five years, limited — stated in the description. It is the longest term stated for a drive on this shelf, where three listings publish none, one twelve months and one a year; the Ultra Flair's description names five years for its range

Five years of warranty, the longest term on this shelf
The joint-largest capacity here at 512 GB, and $0.234 a gigabyte
No write figure, so the single published number is the read speed and the slower direction is unstated

Best for: Half a terabyte on a key that has to be covered by a term rather than a hope, with a password on the files.

The description gives a five-year limited warranty. Seven listings sit on this shelf: three publish no term at all, the Samdata gives twelve months, the SIMMAX one year, the Ultra Flair’s description five years for its range, and this one five years for the drive itself. On a flash drive the term is a commercial promise rather than a statement about the memory — the intro to this section says so — but it is the only promise on the page that anyone can hold the maker to, and this is the longest one here.

Five hundred and twelve gigabytes is the joint-largest capacity on this shelf, shared with the PNY Elite-X Fit. Between the two, this one cost $50 more on October 26, 2026, publishes 130 MB/s against 200, adds encryption, and adds five years of warranty. That is a clean trade and both pages publish enough to make it.

The first bullet gives the read figure properly qualified: up to 130 MB/s, ten times faster than a standard USB 2.0 drive at 4 MB/s, requiring a USB 3.0 port, based on internal testing, with performance possibly lower depending on the host, and 1 MB defined as 1,000,000 bytes. Five qualifications on one figure, which is the most carefully hedged speed claim on this shelf. No write figure appears, so the usual caution applies: a single number is the read figure.

The third bullet gives secure file encryption and password protection, footnoted. The other SanDisk drive on this shelf specifies that protection as 128-bit AES with the operating systems it runs on; this page names neither, so what the encryption is and where it works has to be taken from the sibling listing or from the maker’s support pages. Two listings on this shelf mention encryption and only one of them specifies it.

The title designates the connector — USB-A — which almost nothing else on this shelf does. Several of the seven listings here leave it to be inferred from a photograph or a compatibility claim. On a shelf where Type-C drives exist and dual-connector drives exist, printing the connector in the title is the difference between a sure purchase and a returned one.

The description makes the usual SanDisk claims: a full-length film transferred in less than a minute, footnoted; no internet connection needed to reach the files; 1 GB defined as 1,000,000,000 bytes with actual user storage less. That last note is the usual decimal caveat, and unlike two drives on this shelf it stops short of publishing the usable figure.

At 8 g (0.3 oz) and 11 by 22 by 8 mm (0.31 in) this is the second-lightest drive here. No keyring loop, no clip and no lanyard hole is published, and no ingress rating. At $119.99 on October 26, 2026 for 512 GB this is $0.234 a gigabyte — the third-cheapest American byte on this shelf, and the cheapest among the drives that publish both a speed figure and a warranty term.

The questions that come up before an order

How long is it guaranteed?

Five years, limited, per the description. It is the longest term stated for a drive on this shelf — three listings here publish none at all.

How does it compare with the PNY 512 GB drive here?

This one cost $50 more on October 26, 2026, reads at 130 MB/s against 200, and adds password protection and a five-year warranty where the PNY publishes none. The PNY is faster and bare; this one is slower and covered.

What kind of encryption is it?

The page does not say. The other SanDisk drive on this shelf specifies 128-bit AES with the Windows and macOS versions it supports; this listing names neither.

More USB flash drives

SanDisk Ultra Flair 32 GB, whose own footnote undercuts its headline

A metal thirty-two-gigabyte drive quoting 150 MB/s and then publishing the arithmetic that reduces it: a 1.2 GB film in under thirty seconds is about forty megabytes a second.

Capacity
32 GB — stated in the title and in the reference. The first bullet’s footnote adds that performance varies by drive capacity, which means the headline figures belong to the range rather than to this version
USB generation
USB 3.0 — stated in the title and in the first bullet, which requires a USB 3.0 port for the quoted speed and notes that performance may be lower depending on the host
Stated link rate
Not published on the listing — no figure in gigabits per second appears, only the generation name
Connector type
Type-A — implied by the body and never designated on the page
Stated read figure
Up to 150 MB/s — stated in the first bullet and its footnote, which says plainly that 150 is the read speed and that it varies by drive capacity.
Stated write figure
Given as a multiple and then undercut by the page’s own example — the first bullet’s footnote gives writing as up to fifteen times a standard USB 2.0 drive at 4 MB/s, which is about 60 MB/s. The second bullet’s footnote gives a 1.2 GB film in under thirty seconds, which is about 40 MB/s. Both are published and neither is chosen
Body design
A sleek, durable metal casing — stated in the fourth bullet. At 4 g (0.1 oz) and 13 by 42 by 7 mm (0.28 in) it is the lightest drive on this shelf. Whether a cap is fitted is not stated
Keyring provision
Not published on the listing — no loop, no lanyard hole and no clip is named anywhere, on a drive small enough to lose
Stated ingress rating
Not published on the listing — no water rating, no dust rating and no IP figure appears
Warranty length
Not published in the bullets — the description names a five-year limited term for the range and the bullets do not restate it, so the figure is attached to the family rather than printed as this listing’s own specification

EAN

- Publishes the arithmetic that corrects its own headline: a 1.2 GB film in under thirty seconds is about 40 MB/s, against the 150 on the front
- Names the encryption properly — 128-bit AES, with the Windows and macOS versions it works on and the Mac download it needs
- The headline 150 MB/s is a read figure for the range, and the page’s own example implies about 40 MB/s writing on a real file
Best for: A small, solid drive for documents and photographs, bought with the thirty-second film example in mind rather than the number on the front.

SIMMAX 32 GB swivel drive publishing its usable capacity as a range

The cheapest American listing on this shelf, and the only drive here that publishes what the operating system will actually show — 29.10 to 29.8 gigabytes of a nominal thirty-two.

Capacity
32 GB nominal, with the usable figure published — the second bullet gives an available capacity of 29.10 to 29.8 GB. It is one of two listings on this shelf that publish what the operating system will actually show, and the only one that gives it as a range
USB generation
USB 2.0 — stated in the title and in the third bullet, which adds compatibility with USB 2.0 and below
Stated link rate
Not published on the listing — no figure in gigabits per second appears, and the generation is given as a name rather than a rate
Connector type
Type-A — implied by the body shape and the swivel clip described in the fourth bullet, and never designated on the page
Stated read figure
Not published on the listing — no figure in megabytes per second appears anywhere. The intro to this shelf says nearly every listing states a read speed; this is one of two here that state none
Stated write figure
Not published on the listing — no writing rate appears, which on a USB 2.0 drive is where the practical ceiling sits
Body design
Capless, with a metal clip rotating 360 degrees around an ABS plastic shell with a rubber-oil finish — stated in the fourth bullet, which gives socket protection and not losing a cap as the two reasons
Keyring provision
The swivel clip itself — the fourth bullet describes a metal clip around the body, and no separate loop or lanyard hole is named
Stated ingress rating
Not published on the listing — no water rating, no dust rating and no IP figure appears anywhere
Warranty length
One year — stated in the fifth bullet. One listing on this shelf publishes a longer term for the drive itself — five years on the SanDisk Ultra 512 GB — and three publish none at all

Amazon Basics 256 GB with a write figure, a usable capacity and three published negatives

The only drive on this shelf publishing a write figure as a figure, and the only one that names its factory file system, its four-gigabyte file limit, its usable capacity and the indicator lamp it does not have.

Capacity
256 GB nominal, with over 230 GB stated as available — the third bullet notes that an operating system may show less than the label because of different measurement standards. It is one of two listings on this shelf publishing a usable figure
USB generation
USB 3.1 Gen 1 — stated in the title and in the first bullet, with the fourth requiring a USB 3.1 Gen 1 or USB 3.0 port for the quoted speeds and noting slower operation on USB 2.0 hosts
Stated link rate
Not published on the listing — no figure in gigabits per second appears, only the generation name
Connector type
Type-A — implied by the retractable body and the USB 2.0 backwards compatibility, and never designated on the page
Stated read figure
Up to 130 MB/s — stated in the first and fourth bullets, from internal testing under controlled conditions. The SanDisk Ultra 512 GB on this shelf quotes the same 130
Stated write figure
Up to 30 MB/s — stated in the fourth bullet beside the read figure, a ratio of better than four to one. Several of the seven listings on this shelf publish a write figure, and this is one of them
Body design
Retractable and telescopic, with a keyhole — stated in the fifth bullet, so the connector withdraws into the shell and there is no cap. The seventh bullet states that there is no LED indicator
Keyring provision
A keyhole in the body — stated in the fifth bullet as part of the retractable design
Stated ingress rating
Not published on the listing — no water rating, no dust rating and no IP figure appears
Warranty length
Not published on the listing — no term appears in the title or in any of the eight bullets, which puts this among the three listings on this shelf with none

EAN
0840095889704
- Publishes both figures — 130 MB/s read and 30 MB/s write — where several of the seven listings on this shelf publish no write figure at all
- The only listing on this shelf that names its file system, and the four-gigabyte file limit FAT32 imposes before reformatting
- 30 MB/s writing means a large folder takes four times as long to copy on as off, which the page is honest about and does not make faster
Best for: A buyer who wants to know the write speed, the usable space and the file system before ordering, and will reformat it on the first day.

Others worth having spare

Electriduct 2 in bore and 88.9 × 25.4 mm (3.50 × 1 in) exterior, both published

The only listing on this shelf that says which of its figures is the inside — a 2 in channel inside a 3.5 × 1 in exterior — in a three-raceway kit with four named fittings.

Internal width
2 in (50.8 mm) — stated in the first bullet as "Channel Dimension: 2" Dia", explicitly as the channel. It is the only internal figure published on this shelf.
Internal height
Not separately published — the channel is given as a 2 in diameter, which on a half-round profile makes the usable height about half that
External dimensions
3.5 in (88.9 mm) W × 1 in (25.4 mm) H — stated in the fifth bullet as "Exterior Raceway Dimensions", explicitly as the exterior
Fixing method
Screws, through pre-drilled holes — stated in the fourth bullet. No adhesive is offered and no screws or anchors are stated as supplied
Hinged or lidded profile
Flanged half-round — implied by the 2 in channel inside an 88.9 mm (3.50 in) exterior; no lid, hinge or closure is described
Length per piece
Not published — the first bullet gives "Raceway Length: 59"" and the second gives 3 raceways, without saying whether 59 in is each or in total
Pack quantity
Three raceways — stated in the second bullet
Accessories supplied
Four, each named: one 90° turn, two joint covers and one three-way T — stated in the second bullet. No end caps and no internal or external corners

Yecaye 15 × 10 mm (0.59 × 0.39 in), one cable, 8 pieces

The smallest channel and the lowest price on this shelf — 0.59 × 0.4 in for a single low-voltage cable, eight pieces, adhesive — with every other detail left out.

Internal width
Not published on the listing — 0.59 in is given in the title as W0.59in, with no statement of whether it is measured inside or outside
Internal height
Not published on the listing — 0.4 in is given as H0.4in, with the same ambiguity. The first bullet states the capacity as one low-voltage cable and names four kinds
External dimensions
0.59 in (15 mm) W × 0.4 in (10.2 mm) H — the figures the listing publishes, labeled W and H in the title. It is the smallest section on this shelf
Fixing method
Self-adhesive — stated in the second and third bullets, which name reliable mounting tape with strong adhesive properties. No screws or anchors are mentioned
Hinged or lidded profile
Not published on the listing — no lid, hinge, clip or cover is described in the title or in any of the five bullets
Length per piece
Not published on the listing — the title gives 113 in in total and the second bullet gives 8 channels, which divides to about 359 mm (14.1 in), but no piece length is stated
Pack quantity
Eight pieces — stated in the second bullet, which gives 8 cable channels for any residential or office project
Accessories supplied
Not published on the listing — the second bullet says the kit includes 8 cable channels and "some parts", and nothing is counted or named

STATIONPC PocketCloud Dock, one M.2 slot reached over Ethernet rather than USB

A dock reached over a network rather than by a cable to a computer, with three named backup modes — and no M.2 format, no link rate and no wattage anywhere on the page.

Bay count
One — a single M.2 NVMe slot, stated in the title and in the first bullet. No 2.5-inch or 3.5-inch bay exists
Supported drive sizes
Not published on the listing — no M.2 format is named anywhere, neither 2230, 2242, 2260, 2280 nor 22110, on a device whose M.2 slot is its only position
Supported drive interfaces
M.2 NVMe — stated in the title. Whether the slot also accepts an M.2 SATA module is not stated, and no SATA bay of any kind exists
Solid-state slot support
The whole device is one M.2 slot, stated in the title as diskless. The first bullet adds that modules of different capacities can be mixed between the dock and the portable unit, which follows from there being no array to balance
Offline cloning
Yes, in three named modes — the third bullet gives Full Backup, which mirrors everything, Selective Backup for named files, and Auto Transfer, which syncs automatically. The fourth adds one-click backup through the magnetic connection
Interface standard
2.5-gigabit Ethernet, with Power Delivery charging and USB-A ports — stated in the sixth bullet. It is reached over a network rather than by a cable to a computer, and the connection to the companion device is magnetic rather than a plug
Stated link rate
Not published on the listing — the 2.5-gigabit figure belongs to the network socket and not to the M.2 slot, and the two are different measurements. No figure in gigabits per second appears for the drive itself
Connector type
Not published on the listing in full — the sixth bullet names multiple USB-A ports without a count or a USB generation, and the fourth names a magnetic connection to the maker’s portable NAS. No socket for a host computer is specified
UASP support
Not published on the listing — UASP is a USB mass-storage protocol and this device is reached over a network, so the question does not arise in the usual form. No bullet mentions it
Power supply
Power Delivery charging, with no wattage — stated in the sixth bullet as stable power. The fourth describes the dock as charging the portable unit as well as backing it up, so the figure matters twice and is given neither time
Per-bay controls
Not applicable with one bay, and replaced by a mode selection — the third bullet gives three backup modes and the fourth a one-click backup triggered by setting the portable unit on the magnetic connection
Amazon reference
B0FPCTJZ4C
EAN
0860014318214
- Three backup modes named individually — full, selective and automatic
- Describes a copy held on separate hardware in a separate place, and argues for it correctly rather than offering an array instead
- No M.2 format published, on a device whose single M.2 slot is its only position and which arrives empty
Best for: Someone already using the maker’s portable NAS who wants the second copy to live at home, on the network, and to charge while it copies.
