Publishes the write figure and the limits with it

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.

Amazon Basics 256 GB retractable USB 3.1 flash drive

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

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
Amazon reference: B0B61DGG18
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.

Four things on this page are published that almost nothing else on this shelf publishes, and three of them are limitations.

The first is the write figure. The fourth bullet gives a read speed up to 130 MB/s and a write speed up to 30 MB/s, both from internal testing under controlled conditions. The intro to this section says to look for the write figure rather than the read figure, and several of the seven listings here give one. Thirty against a hundred and thirty is a ratio of better than four to one, which is what a flash drive actually feels like: a quick copy off it and a long wait copying onto it.

The second is the usable capacity. The third bullet states that the capacity shown by an operating system may be less than the label and that the available storage is higher than 230 GB. Two listings on this shelf publish such a figure, this one and the SIMMAX.

The third is the file system, and it is the most practically useful sentence on the shelf. The eighth bullet states that FAT32 is the factory default format, read-and-write compatible with Windows and macOS, and that a file larger than 4 GB requires reformatting to exFAT or NTFS. FAT32 cannot hold a single file above four gigabytes — which is most video files and every disc image — so a 256 GB drive straight out of the packet will refuse a thirty-gigabyte transfer for a reason that looks like a fault. Seven listings sit on this shelf and this is the only one that names its file system at all.

The fourth is the absence. The seventh bullet reads, in full: “Note: No integrated LED light indicator”. Publishing the lack of a lamp is a small thing and nothing else on this shelf does it; one drive here, the Samdata, has one, and five say nothing either way.

The specification around them is ordinary and clearly stated. USB 3.1 Gen 1, with the fourth bullet noting that a USB 3.1 Gen 1 or USB 3.0 port is required for the quoted speeds and that older ports work more slowly. Fifteen times faster than USB 2.0, which given the 130 and 30 figures is a claim with numbers behind it rather than instead of them. The fifth bullet gives a retractable telescopic body with a keyhole, so there is no cap and the connector withdraws into the shell. The sixth claims high-quality NAND flash chips protecting data security, which is a sentence rather than a specification.

The second bullet translates the capacity: 64,000 twelve-megapixel photographs or 978 minutes of 1080p video. At 256 GB that is 4 MB a photograph and about 4.4 MB a minute of video, and both are plausible.

No warranty term appears anywhere, which puts this among the three listings on this shelf with none. At $65.82 for 256 GB this is $0.257 a gigabyte — more than twice the PNY drive of the same capacity on this shelf, which publishes no speed figure at all. That is the trade this shelf offers most clearly: twice the price for knowing what you are getting.

The questions that come up before an order

Why will a large file not copy onto it?

Because it arrives formatted as FAT32, which cannot hold a single file larger than four gigabytes. The eighth bullet says so and says to reformat to exFAT or NTFS. No other listing on this shelf names its file system at all.

How fast does it write?

Up to 30 MB/s, stated in the fourth bullet beside a read speed of up to 130. Several of the seven listings on this shelf publish no write figure, and this ratio is why the intro to this section says to look for it.

How much space will I see?

More than 230 GB of a nominal 256, stated in the third bullet. The difference is decimal counting against units of 1024, plus the file system’s share.

PNY Elite-X Fit 512 GB at 200 MB/s, built to stay in the port

The highest read figure on this shelf at 200 MB/s, in a body small enough to live in a port permanently — and the only listing here that explains what USB 3.1 Gen 1 actually means.

Capacity
512 GB — stated in the title and in the reference. It is the joint-largest capacity on this shelf, with the SanDisk Ultra 512 GB
USB generation
USB 3.1 Gen 1, explained — the first bullet states that USB 3.1 Gen 1 offers identical performance to USB 3.0 under a new name, and gives backwards compatibility with USB 2.0. It is the only listing on this shelf to resolve that naming
Stated link rate
Not published on the listing — no figure in gigabits per second appears, although the first bullet’s equivalence to USB 3.0 places it at five gigabits
Connector type
Type-A — implied by the low-profile body and the hosts named in the fourth bullet, and never designated on the page
Stated read figure
Up to 200 MB/s — stated in the second bullet and in the title, and framed in the third as up to thirty times a standard PNY USB 2.0 drive. It is the highest read figure on this shelf; the others that publish one reach 150 at most
Stated write figure
Not published on the listing — no writing rate appears in the title, the five bullets or the description. Several of the seven listings on this shelf are in the same position
Body design
Micro-sized, low-profile, plug-and-stay — stated in the fourth and fifth bullets as able to remain connected to a host for extended periods without interfering with everyday use. It answers the problem the intro to this shelf names, that a wide drive left in blocks the sockets beside it
Keyring provision
Not published on the listing — no loop, no clip and no lanyard hole is named, which follows from a drive designed to stay in a port rather than travel
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 anywhere on the page, which puts this among the three listings on this shelf with none

PNY Turbo Attaché 3,256 GB, with seven bullets printed twice and no absolute speed

The cheapest American gigabyte on this shelf at just under eleven cents — on a page that publishes no speed figure in any unit, and prints seven of its bullets twice.

Capacity
256 GB — stated in the title and in the fourth bullet, which translates it as approximately 47,349 songs. At 256 GB that is about 5.4 MB a song, and the arithmetic holds
USB generation
USB 3.0 — stated in the title and in the second bullet, with backwards compatibility to USB 2.0 ports named in the sixth
Stated link rate
Not published on the listing — no figure in gigabits per second appears, only the generation name
Stated read figure
Not published on the listing — no figure in megabytes per second appears in any of the fifteen bullets or in the description. The only speed statement is a multiplier: approximately ten times a standard PNY USB 2.0 drive, whose own speed is published nowhere
Stated write figure
Not published on the listing — no writing rate appears in any unit, and the ten-times multiplier is not assigned to a direction
Connector type
Type-A — implied by the sliding collar and the backwards compatibility claim, and never designated. The eighth bullet reads "Compatible Devices: Tablet", which is a scraped attribute row naming no system or model
Body design
A sliding collar, capless — stated in the fifth bullet, which covers the connector without a separate cap to lose
Keyring provision
An integrated loop — stated in the fifth bullet for a key chain or a backpack. It is the only integrated loop on this shelf; the Amazon Basics has a keyhole, two drives a swivel clip, and the rest nothing
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 any of the fifteen bullets. The seventh offers free technical support, which is not a warranty

SamData Five 8 GB drives in five colors, with an activity lamp

Five 8 GB drives in five colors for $21.99 on Amazon.com on October 26, 2026 — $0.550 a gigabyte, the second-most expensive storage on this shelf — with a twelve-month warranty.

Capacity
8 GB per drive, five drives, 40 GB in total — stated in the title and in the first bullet. Eight gigabytes is the smallest capacity on this shelf by a factor of four; the next smallest are the two 32 GB drives
USB generation
USB 2.0 — stated in the first and third bullets, with compatibility given as USB 2.0 and below
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 the swivel clip, and never designated on the page
Stated read figure
Not published on the listing — no figure in megabytes per second appears. The third bullet says high-speed USB 2.0 and gives no number
Stated write figure
Not published on the listing — no writing rate appears anywhere, which on USB 2.0 is where the practical ceiling sits
Body design
Capless, with a metal clip rotating 360 degrees around an ABS plastic body — stated in the second bullet. The same description appears on the SIMMAX drive on this shelf, which suggests one supplier rather than two designs
Keyring provision
The swivel clip itself — the second bullet describes a metal clip around the body, with no separate loop named
Stated ingress rating
Not published on the listing — no water rating, no dust rating and no IP figure appears
Warranty length
Twelve months — stated in the fifth bullet, with free replacement promised for any problem within the first year
