Average Bench: 73.2% (7th of 639)

Based on 5,191 user benchmarks.  Device: VID 0781 PID 5580 Model: SanDisk Extreme

For real world usability this is currently the best 64GB flash drive (superseded by the Ventura Ultra - 2014). It has a very balanced performance profile with an exceptional 4K random write speed. The 16GB version of the Extreme is currently the value leader in the USB 3.0 flash drive shootout. At present there are no viable alternatives to the 64GB Extreme in fact the Corsair voyager GT turbo is the only drive on the horizon that may challenge the Sandisk any time soon. There are however several reports (Newegg, Amazon) of compatibility issues with this, the 64GB version (other versions are fine), so if you do go for the 64GB version, don't throw the receipt away in a hurry. [Feb '13 USBFlashPro]

Blazing fast. Partitioned to half capacity to prolong it's life. Has been working flawlessly since I purchased it new from SanDisk directly back in 2013. I use bi-daily.

Overall very solid stable performer however the slide mechanism will be an obvious point of faileure in the future.

Failed after six months with a problem that seems quite common - could read from drive, but writing would instantly cause it to freeze.—Sep '14

I've tested it in a benchmark and got about 150MB/s for the sequential write speed but when I try to move a 40GB .vdi file (virtual machine), it's only 40MB/s... Going back to use my external hard drive.
