Brilliant USBdrive. I bought the 32gb version which isn't the greatest in capacity, but it suits all my needs. It's casing is pretty large for a usb, and it isn't the most robust-feeling drive I've ever bought, but it has survived quite well so far. That said, you can feel it firmly click to into place when opening and closing, and you won't need to worry about it popping back into its case when inserting into a slot(a common problem with other usb devices). The drive comes formatted in FAT32, which is standard and a good default format for it to arrive in. But, this limits you to only adding files which are < 4GB. So If you want to add stuff such as large videos, you'll need to re-format it into an ntfs or ext4 format (ext4 is only properly compatible with linux though, so windows users should use ntfs).
Its write speeds using USB2.0 reached an average write speed of 30MB/s. Using USB3.0 it reached an average write speed of 60MB/s, Both speeds are pretty excellent. Also it should be noted that my hard drive was working at full pelt and was the limitation when writing to the usbdrive via USB3.0. So, I cannot say what its actual average write speed using USB3.0 is. This brings me onto my IMPORTANT NOTE.
I noticed a 1 star review for this device where they mention that the device crashed their pc. When testing the device on my system my hard drive became inaccessible because it was being entirely used (and working at its max speeds) to copy data onto the usbdrive. This meant that I could do nothing with my system until the file transfer was complete. I was using linux while testing this, so the consequences on windows could be much worse. So, unless you have a REALLY fast hard drive (something like 12000rpm or an ssd drive), either DO NOT USE YOUR COMPUTER UNTIL THE FILE TRANSER IS COMPLETE (and don't worry, it's very fast ;-) ) or use a usb2 slot, it will still run faster than an average usb2 device.
One last note is, having fast speeds are very nice and completely worth it if you're impatient or low on time in life (both in my case), but do consider whether the price is worth it, because it is not cheap.
**EDIT** Sadly I had to decrease my rating of this memory stick by 1 star because of how tricky sandisk have made formatting the drive on windows.
Please read the comments under Mac Nala's review to see how the usb stick can be formatted.
