The SD Extreme 64GB USB 3.0 flash drive scores 196M/s Read & 173.5MB/s Write in the 100MB Sequential test of CrystalDiskMark.

The test results peak at 199MB/s Read in the 1000MB and 4000MB tests. Write test results peak at 186.8MB/s in the 1000MB test. These results surpass SD's advertised capabilities for this 64GB USB 3.0 flash drive, which are based on the 100MB test result.

AS SSD 1.6.4013 Benchmark Source:AS SSD

The AS SSD benchmark determines the performance of Solid State Drives (SSD). The tool contains six synthetic and three copy tests.

In AS SSD we see similarly quick results from the Sandisk Extreme 64GB USB 3.0 flash drive. It achieves a score of 179MB/s Read / 175MB/s Write in the sequential test. These results are in line with the manufacturers advertised capabilities.

SiSoft Sandra 2012 - Removable Storage Source:Sandra

Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance. Higher numbers represent better performance.

The Sandisk Extreme 64GB USB 3.0 peaks out at 188MB/s (read) and 159MB/s (write) in the 256MB test of Sandra 2012. By comparison, the Patriot Supersonic brings up the rear in each test even though both flash drives are USB 3.0 and 64GB in capacity.

8.5GB Single File Time Transfer Test

For this test a single 8.5GB, high definition 1080p .MKV movie file is copied from a Western Digital Raptor WD740 system disk to the removable storage device, then from the removable storage device to the system disk. Teracopy is used to monitor transfer times and speeds. While this test is influenced by the system disk SATA controller, it provides a straightforward real world indication of sustained transfer rates. Higher transfer speeds and lower transfer times are best. Speed and time are monitored with TeraCopy.

The single large file time transfer test is a sign of the times; how long must you wait to share a HD 1080p 8.5GB MKV movie with a friend? I'm sure there are more technical ways of approaching removable storage device timed file transfers, but this is practical and fun....so here it is.

SanDisk's Extreme 64GB USB 3.0 drive was tested on both USB 3.0 and USB 2.0 ports so you can see how it stacks up to native USB 2.0 thumb drives like the 64GB Supertalent Luxio. According to TeraCopy, the 8.5GB file was copied to the SanDisk Extreme USB 3.0 flash drive from the host computer in 2:54 (48MB/s) via the USB 3.0 port, 4:44 (29MB/s) via the USB 2.0.

Conclusions: Sandisk Extreme 64GB USB 3.0 - Very Fast Flash Drive

A good 64GB USB 3.0 memory stick shouldn't require much explaining. Plug it in, copy your files back and forth and carry your data any where - the quicker, the better. With a demonstrated peak sequential read speed of 199MB/s and write speed of 186MB/s in the 1,000MB CrystalDiskMark test, SanDisk's Extreme 64GB USB 3.0 flash drive surpasses its advertised speeds.

Built apparently on SSD class NAND flash, the Sandisk Extreme 64GB USB 3.0 demonstrated itself to be quicker than previous USB 3.0 flash drives PCSTATS tested, by a good margin in fact.

If you've been sitting on the fence about upgrading your collection of 1GB, 4GB and 16GB USB thumb drives, now is certainly the time to take the leap in to USB 3.0. At cost of about $1.33 per GB of storage, or $85USD for the 64GB flash drive, the SanDisk Extreme (model: SDCZ80-064G) is an economical way to move a massive amount of data around with a single USB device. With USB 3.0 speeds running at a theoretical 4.8Gbit/s, that means an 8GB file will transfer before you get tired of waiting! Conventional USB 2.0 devices are much slower.

The USB 3.0 interface does require a motherboard or laptop with a USB 3.0 port to take full advantage of the speed increase, of course. Most desktop motherboards introduced since 2010 support USB 3.0 ports, ditto for notebooks. To sum up, the SanDisk Extreme 64GB USB 3.0 flash drive is without a doubt the fastest USB thumb drive PCSTATS has tested to date! Recommended.
