The Corsair Flash Voyager is an impressive USB stick. Nothing about it is complicated, pop it into a USB 3.0 host and you are good to go. Like any traditional USB Flash disk, write performance will be more limited when you are dealing with lots and lots of small files. But is that the actual intended usage for a USB disk? You surely are not using it say as an SSD. So we don't think so, it's with MP3 files, movies, zip-files, ISO and pretty much large files where a stick like this shows it's muscle. However as you have been able to notice, we were bottle-necked at roughly 330 MB/sec. This USB stick can go faster, make no mistake. This likely is driver issue with the ASUS Z97 motherboard used in combination with Windows 7. As such please consider the benchmarks show today as a rough indication.
One generic note to the industry (both chassis makers and USB storage manufacturers) through, USB flash disks seem to get wider and wider in size, and that's impractical as it can block the USB port next to it. We think the controller inside this puppy can address eight channels of NAND simultaneously, that design combined with the performance that USB 3.0 has to offer will then show us the speeds of well above 300 MB/sec write performance and even over 300 MB/sec READ performance. That makes the Voyager GTX on of the fastest flash sticks we have ever used, and yes it can go even faster. The one thing we did notice that after stressing it hard, the storage unit will get a bit warm. After several benchmark runs the device actually gets hot, well above body temperature. Heat is never good. So the impact of that and the verdict is still out on that one.
The small file I/O operations remain a bit of a bottleneck, but remember, this is a USB flash disk. If you cant find a USB 3.0 port, it will work just fine at USB 2.0 speeds. And sure, Corsair claims read speeds can reach up to 450 MB/s and write speeds up to roughly 350~300 MB/s when used in conjunction with a proper USB 3.0 host and Windows 8, although close, we can't confirm it. But at up-to 330 MB/sec we certainly can't complain either. At 120 USD the 128GB model it is not cheap, but that's the same with any brand in this class and performance level. If money is not the issue then we can wholeheartedly recommend the product.
