Thank you for posting.

It's a good idea to mention the place and purchase date if available.

I think the format can be improved by only keeping the most relevant info.

Like the Brand Name/Model, USB interface, capacity in GB, date of puchase and/or date-related markings on the packaging if present, also the P/N and related markings from the back of packaging if just purchased.

VID/PID, plus NAND ID and its interpretation by Google, Gemini, Grok, ChatGPT etc to get a confirmation on the reported NAND's type and process node size in nm. Also declared power or MaxPower.

Your notes provide very interesting feedback on the drive's behavior in the actual Unraid machine, confirming that the USB 3.XX interface should be avoided.

I'll make a similar attempt in a day or two, by sharing readouts from my older drives from the MLC era.

KIOXIA (formerly Toshiba) BiCS5 3D TLC NAND chip

Just learned something new:

"In modern 3D NAND like BiCS5, the "node size" (or process node/lithography) isn't quoted in the traditional planar 2D sense (e.g., "10 nm" or "15 nm" class), because scaling happens primarily vertically through layer count rather than shrinking the horizontal cell dimensions as aggressively."

Correct. The same is true in CMOS logic semiconductors as well. In planer logic, the node corresponded with an actual physical dimension of a transistor. Starting with 14nm, the industry moved from planer to FinFET, a 3D modeled transistor. The node then became a marketing tool, where they state what the theoretical size of a 2D planer chip would be for equivalent performance.

And as the marketing departments tend to do, they one-upsmanship the competition. TSMC's 14nm was basically the same dimensions as Intel's 16nm.

Microsoft Windows 10 x64 Build 26200

I've been using a Kingston DataTraveler 100 G3 since 2016, but recently I've been seeing some intermittent unreliability when booting, with checksum failures. Given the age of the USB drive, I figured it was worth replacing it with a new one for peace of mind.

I wanted something with better-than-average reliability, but SLC or pSLC drives were a bit out of my budget. There's also a fairly limited selection of industrial/embedded drives that can be easily sourced, at least here in Canada.

I was able to find this Transcend JetFlash 270M for a reasonable price (although still expensive per GB, of course). It's an industrial drive with MLC, and specifically states it has ECC -- I think this isn't uncommon, even in consumer drives, but it seems rare to have it explicitly stated. It also has a TBW rating, for the 8GB drive it's rated for 8 TBW, so 8000 full writes. That's a fairly low TBW rating compared to some other industrial drives, but still should be sufficient for many years of use.

Unfortunately the drive info was unable to identify the controller or the memory, but I did find a datasheet that suggested it may be using 16nm Samsung MLC chips.

I'm not sure that this is actually any better/more reliable than Transcend's consumer MLC drives like the JetFlash 780, but as the price was acceptable I figured I'd give it a go. I've not swapped Unraid over to it yet, but the USB installer suggests it has a unique GUID, so I'm not expecting any problems.

ChipGenius is usually the better tool for the Controller info.

Could you also please post a report from the Kingston for reference?

It is very likely to have either Phison PS2251-03 or PS2251-07 controllers.

Though I'm curious about the NAND.

The 2016 DT100 G3 is right at the transition point- earlier units got Micron MLC which is decent, but later production runs and higher capacities switched to TLC, which is considerably worse for longevity.

... might explain the errors you see.

Marketing fluff..

ECC has been a standard feature in virtually every NAND flash controller for decades — it's not optional, it's a necessity because NAND flash by its nature produces read errors that must be corrected in real time. No USB flash drive ships without it.

Appreciate the share!

Seeing a Swissbit SLC here is a treat.

The price is obviously overkill for a desk-side server, but for anyone running Unraid at a remote site this is the play.

When a "truck roll" to go swap a failed consumer drive costs more than the hardware, paying for industrial SLC is just smart business.

It’s the ultimate buy once, cry once boot drive.

Thanks for posting the USB info output. I'm assuming you've used the Flash Drive Information Extractor utility.

Could you also run ChipGenius just to see if it shows any Flash ID info?

Would you mind checking if any S.M.A.R.T data comes through? A quick way to test is via HWiNFO

Innodisk has a S.M.A.R.T readout tool for their industrial USB drives called iTracker, designed specifically for USB drives -- it provides visualized S.M.A.R.T information, including P/E cycles and health status.

But there's no "one-click" download on the main Innodisk site.

It's managed through the MyInnodisk portal and requires registration.

Hopefully it helps. I used Flash Drive Information Extractor 9.4.0.645

ChipGenius Provides a Flash ID code: 983C95937A51 - Toshiba - 2CE/Single Channel [MLC] -> Total Capacity = 64GB

HWiNFO is not being passed S.M.A.R.T data.

I failed to find the S.M.A.R.T readout tool(set) on the innodisk site.

It appears that myinnodisk access is granted to distributors & partners.

Thank you!

Flash ID code: 983C95937A51

it's Toshiba's A (Advanced) 19nm a "half-node" shrink of the original 19nm node.

It's post-2016 production using 15 nm Toshiba MLC.

Thanks again for providing that detailed NAND readout!

Do you mind if I copy that output over to my MLC collection thread to archive specs for different MLC drives to keep all this technical data in one place.

I’ll make sure to credit you for the dump.

Edited May 4May 4 by Lolight

You may copy the info.

I'm just hoping to make finding stable usb drives easier for folks.
