Wow, that's a lot of pissing a moaning about a niche product.

I don't think people appreciate just how small these things are. That Silicon Power Jewel sticks out 2-3x as far. When this thing is plugged in, it's smaller than a Logitech Unity adapter. Frankly, I'm surprised at how small SanDisk makes these, and they are high-quality to boot.

Does everyone need a tiny USB 3.0 drive? Not even close. But these things are great if you have a USB input on, say, a car stereo head unit. If it supports external drives to run video screens, the extra speed would be nice when you're loading it with files. I also use one of the USB 2.0 versions to watch videos via USB OTG on my Nexus 7, in case I'm visiting relatives who have terrible net speeds (or NO internet) and live in a zone without 4G data. If I'm already hanging a dongle off the tablet, the last thing I want is a full-size thumb drive.

Yes, I think we do know how small these things are

The Jewel sticks out 2X as much as the Mushkin Atom which is the same size as this Sandisk

For a car stereo head, the mushkin Atom is a better deal with 145MB/sec "Actual" tested read speeds and far lower price

and if you want it black, you can easily make it black
I'd try plasti-dip for a soft rubberized black coating but you can use a magic marker if you like

20 and 40 MB/sec? Sandisk is in a grey area by calling that USB 3.0 speed.

Even my now-dated Corsair Survivor 32 GB 3.0 blows them away with 90 MB/s reads and 40 MB/s writes and my cheapy PNY 128 GB 3.0 drive annihilates 'em.

Is the small form factor really worth being stuck with "USB 2.5" speeds?

No, these are faster than your Corsair Survivor overall, based on the specs you posted. *Write* speeds are 20MB/s for the 16GB and 40MB/s for the 32GB and 64GB drives. Read speeds are 130MB/s for all three. So:

  • SanDisk Ultra Fit 16GB: 130MB/s read, 20MB/s write
  • SanDisk Ultra Fit 32GB: 130MB/s read, 40MB/s write
  • SanDisk Ultra Fit 64GB: 130MB/s read, 40MB/s write

EDIT: Amazon has the read/write speeds posted for the Corsair Survivor USB 3.0 you referenced:

  • Corsair Survivor 16GB: 79MB/s read, 21MB/s write
  • Corsair Survivor 32GB: 80MB/s read, 40MBs/ write
  • Corsair Survivor 64GB: 85MB/s read, 70MB/s write

Thanks for the info.

Now I'm less concerned about Sandisk as 130 MB/sec read is what I'd call USB 3 speed. The write speeds still concern me as they're still pretty low IMO for a modern USB 3 drive.

I think the size is overly small. Sometimes doing something just because you can is not a great idea. I want one that is large enough to attach to my key-ring (to replace the USB 2 one I have carried around for years) so not overly large but large and sturdy enough.

Try these

32GB / $25
240MB/sec write
80MB/sec read
Lifetime Warranty
http://www.newegg.com/Product/Product.aspx?Item=0BD-0095-000B1

16GB / $10
90MB/sec read
60MB/sec write
Lifetime Warranty
http://www.newegg.com/Product/Product.aspx?Item=9SIA4AJ1MX7847

I can't verify read/write speeds as these are manufacturers claims
but I trust newegg customer reviews over manufacturer's claims any day of the week

They have an 8Gb model with 90MB/sec read and 60MB/sec write for $6 if you'd like to give an honest review without wasting too much money

Under capacity, over priced. Not interested.
There are other small foot-print products that
perform admirably well at a fraction of the cost.

Waste of money

The Silicon Power Jewel J06 32GB reads at 155MB/sec Writes at 20MB/sec average, waterproof, Lifetime Warranty and looks better

http://www.newegg.com/Product/Product.aspx?Item=9SIA4AJ1UX1746

comes in 8GB for $8
16GB for $10
32GB for $16
and 64GB for $30

If you're looking for Lame-Ass write speeds, the Silicon power is a much better buy

You should actually test that claimed write speed of 40MB/sec for the 32GB model
I hate when you just take the manufacturers claims and run with them

was that average or burst speed?
was that synthetic or real world?
was that advertised or end user speed?

We don't have this in-house to test, hence why we're careful to point out that these are manufacturer rated specs. Also, bear in mind the prices are MSRPs -- street pricing is likely to be a lot lower once they show up at places like Newegg, etc.
