4 out of 5 eggsDurable drive, but at what cost?

Pros: So this is my first review of a USB drive. Corsair is a good brand for USB storage; I’ve used many of their products in the past. At the price point of this particular drive, there are other, cheaper, options available for the consumer. Corsair is trying to fill a niche of durability, and so that’s what I’m going to be testing.

Unfortunately, I don’t have access to a computer to test the USB 3.0 speeds… I thought my work computer had USB 3.0. Regardless, here’s what I found on 2.0:

Copy files to the stick:
250 files, about 2.5 megs a piece: 8.5 MB/s – 10 MB/s
1 File, 1.5 gigs: 8.5 MB/s- 10 MB/s
1 file, 100 megs: 13MB/s – 25MB/s

Paste files from the stick:
250 picture files, about 2.5 megs a piece: 140 MB/s – 150 MB/s
1 File, 1.5 gigs: 400 MB/s
1 file, 100 megs: Fast enough that the windows prompt doesn’t even show. I.E. instantaneous

I tested this out with an older USB 2.0 drive that I had, and the speed differences were notable. The Corsair drive was anywhere between 10x – 20x faster in all cases. But that’s really not what this drive is about. I’m sure that most drives available today would perform similarly, in terms of read/write speeds.

So, now we enter the durability phase. Corsair is advertising this USB drive as being durable. One thing I’d like to note is that the male USB interface automatically retracts when you rotate / close it, and vice versa when you open it; this prevents it from being bent accidentally. Also, the housing, itself, seems pretty rugged. The drive, itself, is encased in a hard rubber, and I think the metal clip it’s in is aluminum? I’m not certain on that, so don’t quote me! :)

Here’s what I’ve done to stress test its durability: I’ve dropped it from 4’-0” (to simulate if it just slipped out of your hand), dropped it from 1 story, 2 stories, and 3 stories. It still worked just fine. I also attached it to my key ring with my car/house keys, and repeat. It still worked just fine. This thing is pretty durable.

Cons: The only cons to this device is the cost. I believe that it's more durable that it's cheaper competitors, so you need to consider just what exactly you need in a USB drive.

Other Thoughts: My day job is Structural Engineering, and one of the aspects of that is being out in the field inspecting bridges currently being used. I would recommend this drive to anyone who needs to have electronic files on hand during times where the drive might be damaged (i.e. when I’m out in the field). If you’re looking for a drive to just store files on as a backup and keep it in a desk, or pass files onto someone else, then you may want to save a few bucks and consider getting one of the cheaper ones.

4 out of 5 eggsNice Designed Thumb Drive, Not USB 3.0 Write Speeds

Pros: - Nice Design: I really like the rubberized casing of this thumb drive. While there are no moving parts internally, I assume this would help with impact shock absorption. The additional aluminum cover is a nice add-on to, but help project the connector. I really like the retractable design and it's construction feels solid.

- Low Priced (About a buck per GB)

Cons: The USB 3.0 write speeds were not impressive. While they were faster than the USB 2.0 speeds, they still were much slower than expected.

Other Thoughts: I ran benchmark tests with CrystalDiskMark 3.0.2 x64. While the read speeds were a pretty big difference, the write speeds were lower than expected for USB 3.0. My test results are below:

USB 3.0
Sequential Read: 82.71 MB/s, Sequential Write: 10.59 MB/s
512K Read: 77.94 MB/s, 512K Write: 0.796 MB/s
4K Read: 8.206 MB/s, 4K Write: 0.082 MB/s
4K QD32 Read: 8.879 MB/s, 4K QD32 Write: 0.053 MB/s

USB 2.0
Sequential Read: 30.06 MB/s, Sequential Write: 8.766 MB/s
512K Read: 29.34 MB/s, 512K Write: 0.586 MB/s
4K Read: 5.386 MB/s, 4K Write: 0.038 MB/s
4K QD32 Read: 5.397 MB/s, 4K QD32 Write: 0.050 MB/s

Overall, this is a nice, well designed USB thumb drive. However, I feel the total increase in USB 3.0 write speeds is under par to be a true USB 3.0 thumb drive. However, this device is priced cheap and Corsair is a trusted name in the memory industry. That being the case as well as many USB 2.0 drives falling in the same price range, this device is priced very well for what you are getting: - A USB 3.0 readable device, with slightly better than USB 2.0 write speeds.
