First, a few notes on the drive itself. I don't think it can be beat value-wise as USB 3.0 drive. I've owned the 16gb model for a little over a year now, and it has seen heavy use as a general use drive, a media drive, and it's even been used multiple times as an OS install drive. Since I work in IT, this drive has been put through the paces plus some. A week ago, the internal mechanism that allows the drive to retract finally completely broke. It still worked, but was a pain to use because it was constantly trying to close itself and often would unplug itself from the computer. Plus it was a general pain to plug it. So, here is how I fixed mine. **Note, I'm aware this is a macgyver, but hey, it works.**

First, find some superglue. Everybody has superglue! Now, while the flash drive is in the "closed position" (ie the blue plastic is sticking out as far as it can), spread some superglue on the blue plastic. Next, get some vice grips or vice clamps, and clamp the drive into the "open position" (ie the usb plug is sticking out as far as it can). If you don't have vice grips, you could probably still hold it in the open position by wedging it between two heavy objects. Anyhow, this means the superglue ends up between the blue and the white plastic. After this, I also beaded some superglue in the little gap between the blue and white plastic just to reinforce it, but I don't know if this is required. Let it dry overnight. The end result will be a fast and cheap USB 3 flash drive that is always in the open position. Mine has now been like this for a week and it is still solid. Honestly, I wish I had done this a long time ago, because the built in mechanism is just a pain.

I was stunned at how fast this drive is even with USB 2.0. Using Crystal DiskMark with a 100MB file, it hit 32 MB/sec Read and 20 MB/sec Write with USB 2.0. With USB 3.0 the numbers were 64 MB/sec Read and 24 MB/sec Write. So, although USB 3.0 doubled the Read speed, the Write speed was not much different and still very fast under USB 2.0. I also bought the Super Talent Express Duo USB 3.0 16 GB Flash Drive ST3U16EDB and found it to be slightly faster on Read performance (71 MB/sec with USB 3.0 and 36 MB/sec with USB 2.0). But I don't like the SuperTalent's loose cap and prefer the spring-loaded retractable Patriot design. There are faster flash drives but none that I could find at this price level.

I bought this drive from a B&M because it was on sale. I won't mention the name since it is probably verboten in an Amazon review, but suffice to say that, like Amazon, they're an authorized reseller.

Performance :

This is a USB 3.0 device but backwards compatible with USB 2.0 (and 1.1, of course, but you'll grow old filling this drive at USB 1.1 speed). The drive came pre-formatted in NTFS. The package says "up to 60 MB/s read / up to 25 MB/s write". I tested it on my i7 920 computer with USB 2.0 and h2testw. I managed to get about 30 MB/s read and 19.4 MB/s write. (See 4/19/12 edit below for USB 3.0 testing. Spoiler : it is good). h2testw writes large files, and has been pretty accurate for sustained large read / write numbers. It is possible that on a USB 3.0 system, I might get better result, but these numbers are pretty decent for a USB flash drive.

Edit 10/17/11. I reformatted it as FAT32 and re-ran the test. The results were pretty much the same. In fact, it is slightly less than 1 MB/s slower with FAT32 for reads.

Edit 4/19/12. I installed a PCIe USB 3.0 interface card and re-tested the drive. I reformatted it as exFat and ran it through h2testw. I'm getting 24.9 MB/s write and 57.4 MB/s read, very close to the manufacturer specified speed. I'm changing my review to 5 stars because of this.

If you're not familiar with h2testw, it is a small, free, Windows utility that will write large (1 GB) files of pseudo-random data to your drive, and read it back to verify that there are no errors. I recommend doing this, as it not only gives you a rough idea of how fast your device is, it also ensures you did not end up with a fake drive (a smaller drive altered to appear as a larger one).

I recently have outgrown my old flash drives and needed to find a good brand/design to standardize on. My past favorites are my Sony Turbovault and SanDisk Cruzer Titanium, both 2GB models. Back when I bought these high-performance flash drives, they ran in the range of $45-$60 even at discount sources. The SanDisk Cruzer Titanium is unsurpassed for durability because of its hard metal shell and retractable connector. The Sony drive was faster and slimmer, also cost a little more.

Anyway, those models are not really available or have not been updated to faster speeds, so was looking at new offerings. As a rule, I will not buy a flash drive that has a separate cap, or a swivel cover. Surprisingly, most of the high-performance models still have the separate cap, when lesser models in the same brand have a retractable connector. The thumb-switch style of the Cruzer line has been my favorite. This Patriot drive actually works like a pen with a thumb clicker, except you hold it a little differently. One cool inherent feature of this design is that when you disconect it from the computer, the connector is automatically retracted. This is nice that you don't have another step after removal.

So, most of you probably just want to know how is the speed? Well, it's a bit faster than my old drives even through USB2, and it has VERY fast read speed on USB3. There are many ways to test, but to see the fastest speeds, I just copied a large file to and from the drive, using my Dell Vostro 3450 (7200rpm HDD and USB3 ports).
USB 2.0 - 31MB/s read & 20MB/s write
USB 3.0 - 63MB/s read & 23MB/s write
This is quite fast, and I do expect to purchase a 32GB model to use as my primary flash drive.
