Top Customer Reviews
(1)Its maximum read speed, 200 MB/sec is the fastest of all USB 3.0 or USB 2 flash drives tested including more expensive Lexar Triton, Verbatim V3 etc. Its 185 Mb/s is top 5 in writes behind Triton etc. This saves you a lot of time when copying or reading files. This makes a huge difference if you are waiting at your computer for the copying to finish.
(2)It uses USB 3.0 and can be up to 10 times faster in reads and writes than the fastest USB 2 flash drives if inserted in "USB 3.0 port".
The speed gain is much less if inserted in USB 2 port. The speed can be verified with a free software called atto, downloaded from the internet.
(3)It is like carrying almost the fastest 10000 rpm hard drive in your pocket, is more reliable with no moving parts, is smaller 2.79 inch x 0.84 x 0.45 and uses much less electricity.
Its maximum reads 200 MB/sec are faster than the maximum reads or writes 133 MB/sec of the fastest 7200rpm SATA 6 GB/s hard drive 1 TB HGST Travelstar 7K1000. But slower than the maximum reads and writes, 209 MB/s of Western Digital VelociRaptor WD1000DHTZ hard drive(1 TB, 10,000 rpm, SATA 6 Gbit/s). The results are from tomshardware.
Its speeds are much slower than solid state drives. SanDisk Extreme SSD 240 GB has 550MB/sec reads, 520MB/sec writes.
(3)It comes installed with 128-bit AES encryption and password software, like Verbatim, to protect your data which is stored in a "vault" from unauthorized access. You can also store non-sensitive data on the drive outside the vault.
Warning : My Norton Internet Security software rates the RunSanDiskSecureAccess_Win.exe, the software bundled with the drive

As you can see this drive caps out the transfer speed of the USB2.0 port on both sequential tests and random read 512Kb, probably random write 512Kb as well but I'm not familiar enough with the USB2.0 design architecture to make that statement.

To do this, you right click on the drive letter in Windows Explorer and choose "Format" from the menu. A dialogue box will open, and you must choose various options. Select the NTFS file system. If you choose "quick format," the formatting takes only a few seconds. I think if you want to check the drive for errors during the process, you should not check quick format, but the formatting takes much longer. From what I have read, it is usually recommended to use quick format unless you have reason to believe the drive is damaged.
Any files that are on your usb drive will be deleted during the formatting process, so copy them to another drive before you format.
A number of reviewers say they have not been able to format the drive to NTFS. Initially, I was unable to do it also. When I tried to format to NTFS, I right clicked on the drive and then clicked "Format," but the dialogue box did not allow me to choose any options and I could not change the file system to NTFS. So, I went to the Sandisk website for support. On their website, they say that in order to format the drive, you must first do the following:
Optimize the flash drive for performance.
1. Plug in the device to the PC.
2. Double-click My Computer.
3. Right-click on the flash drive, then select Properties.
4. Click the Hardware tab.
