Speeds are crazy fast compared to the older USB 2.0 drives.
Tex
Plus I like the retracting mechanism; instead of just sliding in and out like other flash drives, this one clicks and locks into place.
The Chairman
The main issue is that the security software runs all the time in the foreground and it only allows you to access one file at time.

Product Packaging: Frustration-Free PackagingSize Name: 64 GB Verified Purchase
I highly recommend this Sandisk Extreme 64GB flash drive because :

(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
..............unstable.

Product Packaging: Frustration-Free PackagingSize Name: 32 GB Verified Purchase
I am now an owner of 3 of these drives, all 32GB. I have to say these are impressively fast drives, even on a USB2.0 bus. So many users are still using USB2.0 transfer speeds so I thought I would post a CrystalDiskMark benchmark and a real-world transfer comparison against the next fastest USB device I own, a Patriot XT Boost 16GB (USB2.0). A 'typical' upgrade you could say from last generation to current generation.

-----------------------------------------------------------------------
SanDisk Extreme 32GB - NTFS - Empty (USB2.0)
-----------------------------------------------------------------------

Sequential Read : 36.582 MB/s
Sequential Write : 30.700 MB/s
Random Read 512KB : 35.945 MB/s
Random Write 512KB : 22.678 MB/s
Random Read 4KB (QD=1) : 7.992 MB/s [ 1951.2 IOPS]
Random Write 4KB (QD=1) : 7.830 MB/s [ 1911.7 IOPS]
Random Read 4KB (QD=32) : 6.866 MB/s [ 1676.4 IOPS]
Random Write 4KB (QD=32) : 4.423 MB/s [ 1079.8 IOPS]

Test : 500 MB [A: 0.3% (0.1/29.8 GB)] (x4)
Date : 2012/12/28 11:28:29
OS : Windows 7 Professional SP1 [6.1 Build 7601] (x64)
Ver : CrystalDiskMark 3.0.2 x64

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.

Real-world test: (USB2.0 bus)

Decompress 'install.wim' from Windows 8 Pro x86 package located on SATA HD to USB drive.
Package contains 61,541 files in 13,011 folders with a total uncompressed size of 8,029 MB.

SanDisk Extreme 32GB - NTFS: Completed in 10mins 11seconds.

Product Packaging: Frustration-Free PackagingSize Name: 64 GB
When I got this drive, I tried to copy a large file to it, but it wouldn't copy. I kept getting an uninformative error message. I eventually learned (from my own research, since nothing about this was stated in the box) that this was because this drive comes formatted in the Fat32 file system, which allows a maximum file size of 4gb. If you want to store larger files on this drive, you must change the format to the NTFS file system.

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.
5.
