    • Drives fail with "overuse"!!
Size: 256GB
I've bought 14 of these drives over the last eight months. As of today, FIVE of the fourteen have failed. But when I say failed, they haven't lost the data on them; they are simply locked and won't mount. A phone call to Sandisk and I'm told that this is a "safety feature" so my data won't be lost. How is it a "safety feature" when I can't access my data? The only solution Sandisk has offered is to replace the drive and I can send the "failed" drive to a third party and pay $50 to have the data recovered. That's NOT a solution! After paying close attention to when and how this happens, it appears to be caused by moving large blocks of files from one of the Sandisk drives to another location. At some point during the copy, an error message pops up that the USB drive can no longer be read and it will vanish from my desktop. No amount of moving it or trying to mount it using the computer's disk utilities or trying to read it in another USB port will help. It's locked and nothing will unlock it! Do NOT buy these if you're planning to move files around. I believe they heat up too much, which then triggers this "safety feature" and causes you to be unable to access your data. I'm extremely unhappy with this "safety feature" and with Sandisk's response to the issue. Will NEVER buy anything Sandisk ever again! ... show more

Capacity is great. Small profile is great. That claimed 130MB is read speed. Please note... write speeds state UP TO 15X over USB 2 speeds. Key words here are UP TO. I use this device to store flac music files for playback in my car. I have plugged this drive into USB 2, 3 & 3.1 ports for writing purposes. I have seen extremely marginal performance differences between USB 3 & 3.1 (fluctuates between 35 - 55 MB when writing anywhere from 200MB - 2GB at a time). On a USB 2 port I get speeds around 20 MB on average. I will post test results and adjust figures as needed later as I am going from memory at this point. On another point, the frame of this no longer appears to be made of metal. I would say it is made of some type of composite material. I believe this was done with a purpose on the manufacturer to alleviate the heat issues with the previous model (which I also own) While it still gets warm while writing, it no longer gets hot to the touch like the previous model did. The heat dissipates much quicker. Given that, I do worry about the longevity and duability of this device should it have to be used and plugged in frequently in many devices. Overall, it serves my purposes. Write speeds could be better and durability could be an issue. Hence, my reason for three stars. **********Edit********** I have included Crystalmark tests (1 @ 500MB in size for USB 2 & 3). I did 5 tests while having it plugged into a USB 3.1 gen 2 port (1 of each @ 500MB, 1GB, 2GB, 4GB & 8GB). Speeds start dropping down the larger the test file was. Speed breakdown for the images is as follows for those that were wondering: USB 2.0 image is the read speed of 40.22 & write speed of 17.01 USB 3.0 image is the read speed of 126.2 & write speed of 50.41 USB 3.1 gen 2 images are the remaining 5 images as well as the windows copying images Just for a test, I copied over an approximately 4GB video file to the drive via the USB 3.1 gen 2 port (see the windows copying images). At the halfway point of the file, the speed starts to drop off and never recovers. Looks like the video file maintained a good 64 MB until the halfway mark. ... show more

    • Not durable enough for every day transfer use.

The pros. Small form factor, and doesn't get super hot like the metal one. The cons. It is made out of paper thin plastic. I had it come apart inside of the only USB port my Surface pro has. It was quite the challenge to fish the piece out without damaging my device. I would only recommend this if you plan to install it and leave it. If like me, you need a portable device to transfer files from machine to machine, look elsewhere. ... show more

    • Still works...

Really wish it wasn't plastic. After constant use it started to crack, then broke in my laptop. I needed to fish the broken pieces out with a blade. I am sticking to metal drives from now on as I am noy satisfied with this.

    • Older model was better.
Size: 256GB
We've been using the previous model of these ultrafit drive for years as an easy way to add permanently-attached storage to MacBook Pros (all with USB 3.0+). Just plug it in, format it, and forget it. They always worked great and always performed well. We just ordered 3 of this new model (the 256GB) and noticed very slow write-speeds. Checking System profiler it's easy to see that the old model registered full-speed every time it is inserted, but this new model often reverts down to USB 2.0 speeds. We've tested all three drives and it's happening with all three of them. If we didn't desperately need the 256GB of storage in a tiny form-factor we would return all three of them. As it stands, the performance issue really won't be much of an issue (they mostly house lots of relatively small files), but if you will be relying on needing reliable USB 3.0 speeds you may want to look elsewhere. ... show more
