Top customer reviews

I bought mine in 2015 and I no longer have a use for it anymore but I tested the speed again in 09/2017 and still getting decent speeds. Some people have been disappointed for not getting the same kind of speed but one thing to be aware is, the speed tests depend on the type of motherboard and USB controllers. Other factors include the number of other USB devices you have connected to your machine. After all, the USB devices have USB bandwidth they share. Another factor is whether you plug it to a USB 2.0 port which ultimately limits your speed to a USB 2.0 speeds.
For the 32GB version of the drive, the real-world performance, using the default file system (FAT32), the default Windows policy (quick removal) and transferring LARGE files, is around 20MB/s write and 150MB/s read. For the 128GB model, the write speed increases to ~30MB/s, with read speed remaining unchanged. Transferring lots of small files at once will be slower than transferring large ones.
You're not going to get symmetrical 100+MB/s read/write speeds at this price point.
When it comes to writing data, these drives will have a small cache that's far quicker than the rest of the available storage. Any advertised write speeds may be referring to that cache. If you write a small enough amount of data to the drive, it will be written to that cache at a high speed, then in the background that data will be trickled out of the cache and into the slower part of the drive. However, when writing larger quantities of data, the cache will be saturated, at which point the write speed will drop to that of the regular TLC memory.
It's exactly the same for their low-mid range SSDs; the 840 EVO is advertised as having ~500MB/s sequential write speeds, and CrystalDiskMark will appear to back this up, but that's because it's not testing any deeper than the SLC "TurboWrite" cache. If you run a SUSTAINED sequential write operation on the 840 EVO, it'll be forced to write directly to the regular TLC NAND. You will see the speed plummet to <150MB/s after about 3GB of data has been written, and it will remain at that speed until you stop writing. To get sustained sequential write performance at 400+MB/s, you would need had to have bought the 840 Pro, which uses faster MLC NAND for the entire storage area.
make sure you look carefully at the benchmarks people are posting. One of the reviews here is showing the 32GB model/packaging, but the CrystalDiskMark result is for a 128GB device. Also pay close attention to the benchmark software version and settings. For example, new versions of CrystalDiskMark are running a different set of tests to old versions, so the results aren't necessarily going to look the same even if the device is performing identically. The default "test size" setting for CrystalDiskMark is 1GiB, but people are posting results taken with that set to 100MiB. This will make all the difference between getting a ~20MB/s write result and a ~100MB/s write result, presumably because 100MiB isn't big enough to saturate the abovementioned cache. I've provided CrystalDiskMark results from two different versions of the program and with different settings to illustrate all this.
Anyway, I have four of these drives. I haven't had them long enough to comment on longevity, but so far so good.
They get quite warm, but I haven't seen any overheating/thermal throttling. I pulled the entire 128GB of data off one drive, and it was reading at the same ~150MB/s the entire time.
The shape of the drive is slightly inconvenient because it can cover a neighboring port if the ports are stacked closely together (eg. motherboard IO cluster).
There are so many different designs for flash/thumb drives out there; there's something for everyone. I wanted something that looked solid and simple, was reliable, and fast. This was it. Here's why:
• The one piece body feels solid, but lightweight, and looks gorgeous
• There is no cap to lose, and the USB end is sturdy enough to stand up to heavy use
• The little hole can be used to attach to a key ring if necessary
*** NOTE ***
Please be aware that this drive is capable of USB 3.0 transfer speeds of "up to 130MB/s". You will only get this speed if the computer you are attaching it to also has USB 3.0, otherwise it is backwards-compatible and will reduce to USB 2.0 speeds. You can tell if it's USB 3.0 if the inside port is a blue plastic, or if the port is labelled "SS" (SuperSpeed).
The design looks like it could've been built by aliens [see photos]. It's so simple, yet just works. It's solidly-built, with no small pieces to lose, and big and shiny enough to be visible, and is blazingly fast. Recommended.
If you are looking for a quality USB drive that is also easy on the eyes or doesn't come with a cap that will end up getting lost, look no further.
I will update this review if anything happens or changes in the future. If I don't, assume it is still working flawlessly and there are no problems to report.
