1. SPEED. After all, that's probably the main reason why you're thinking about buying this. I've had mine for almost a week now. Been using it everyday, moving a bunch of files from one computer to another to test the speed. It's pretty fast. As others have noted and as the spec indicated, I got 20-25 MB/s write speed when connected to the USB port on the computer. Writing 10 files totaling 5 GB took under 4 minutes. Other test copies yielded similar results, whether it was one large file or many small files. This is nowhere near the fastest of the bunch, but this is almost twice as fast as any USB sticks that I've used. Surprising was the write speed of this stick on USB ports. I got speeds almost as fast as USB ports. Writing GB took about 7 minutes 30 seconds on several tests (~18 MB/s).
2. HOUSING. The spec says that it is made of aluminum. And it feels like aluminum. It's very light but feels sturdy. The cap and the butt end are made of plastic.
3. DESIGN. I think they should stop making USB sticks with caps. In too many cases, the caps will eventually get lost. I much prefer a cap-less design, whether it's an exposed tip or a slide. If they must have caps. then it should somehow be attached to the USB stick. This is especially bad on this stick. There is a loop on the butt end, presumably so that you can attach a lanyard through it. But if you use a lanyard, then the cap no longer fits on the end. Someone wasn't thinking at ADATA. Hello?!? McFly?!? But other than this defect, the overall look is actually very handsome. Pretty.
As of this review (July 2012), this was the cheapest 16GB USB flash drive that I could find online. For the price, I can't complain too much. I'd probably buy a few more in the next couple months. Unless Kingston came up with a USB drive with this design: Kingston Digital DataTraveler SE9 (DTSE9H/16GBZ).
If you're looking to save a few bucks, this ADATA 16GB Pro is but it's slow.
I compared it to a USB 16GB SanDisk Extreme and 32GB Lexar JumpDrive. My test was unscientific but repeatable. Here's what I did under Mac OS X Mountain Lion on a 2012 MacBook Pro 13":
- Partition each flash drive as one Mac HFS+ volume using the Mac Disk Utility.
- Placed a folder on my desktop which contained a iso file and iso file. These are just iso images for the Mac OS X and Oracle Linux operating systems. The file details are not important but the folder which I called TEST contains these two large files totaling about 8GB.
- Drag the TEST folder to the USB flash drive being evaluated and time how long it took to copy the TEST folder.
5-min. 40-sec: ADATA 16GB Pro
3-min. 50-sec: Lexar 32GB JumpDrive
2-min. 14-sec: SanDisk 16GB Extreme
- Repeat the test by deleting the TEST folder from each USB flash drive and repartition each. Start the same test again.
Results were repeatable to within +/- 2 seconds for each USB flash drive and the ADATA repeatedly comes out slowest of the bunch.
Like I said, not a true 'benchmark' or scientific test but in real world use copying large files, the ADATA Pro is one slow pig. The SanDisk Extreme is more than twice as fast!
First of all, when I bought this flash drive it was $2 cheaper. It was $14, now it's $16. The build quality on this flash drive is superb. It has a solid metal case and the plastic cap can go one the end when the flash drive is uncapped (kind of like a marker). It is USB so if you have a computer with a USB port it's faster. Here are the benchmarks for the drive:
Sequential Read : MB/s
Sequential Write : MB/s
Random Read 512KB : MB/s
Random Write 512KB : MB/s
Random Read 4KB (QD=1) : MB/s [ IOPS]
Random Write 4KB (QD=1) : MB/s [ IOPS]
Random Read 4KB (QD=32) : MB/s [ IOPS]
Random Write 4KB (QD=32) : MB/s [ IOPS]
By comparison, a Sandisk USB flash drive got these results on the same computer:
Sequential Read : MB/s
Sequential Write : MB/s
Random Read 512KB : MB/s
Random Write 512KB : MB/s
Random Read 4KB (QD=1) : MB/s [ IOPS]
Random Write 4KB (QD=1) : MB/s [ IOPS]
Random Read 4KB (QD=32) : MB/s [ IOPS]
Random Write 4KB (QD=32) : MB/s [ IOPS]
USB definitely made this Flash Drive much faster than a USB flash drive. Here are the test configurations for both tests.
Test : 50 MB [F: ( GB)] (x1)

In conclusion, I would highly recommend this flash drive.
