Sandisk Ultra Dual pendrive is a 'must have' item for smart media storage management ....Unique product with smart concept...!!

Wonderful deal in great price! Data transfer rate is very high. Indeed, a great product by Sandisk!

Great value to use in the tablets and digital cameras. We've had no problems using them both in the devices and as we are downloading.

Easy To Use; Great Value; Large Capacity

I loaded a number of files on the flash drive and the first time that I tried to review the files, I could not access the drive, then could not even erase and reformat the drive. Costco's return policy has been great.

SanDisk sent their Ultra 64GB USB 3.0 make of their ultra series flash drives, which is advertised to be up to 4 times faster than USB 2.0 drives in comparison to their Cruzer USB 2.0 counterparts. However for such flash drives, any brands mostly point out the read speed.

5 Years Warranty; Retractable design

Bad write performance; Not recommended for frequent file transfer purposes

Good performance for a USB 2.0 flash drive; SecureAccess software protects files in encrypted; password-protected "vault; USB connector protected by sliding mechanism; Compatible with Windows XP/Vista/7 and Mac OS X; Nice looking; lightweight design; Five year warranty; Reasonably priced

10 MB/s write speed only applies to the first 20 MB of the data transfer; Includes only 2GB of online storage

The flash drive has a slow write speed despite the available and fully functioning USB 3.0 port on my neighbors desktopPC. I am currently transferring 20 GB of data, without any increase to the expected 40 mb/s speeds as advertised. Reasons?

Do not, I repeat do not, use the back-up Vault whatever it is called. I followed the 12 page pdf directions & set-up "My Vault" and tried to copy about 12 GB of photos.

Lightweight

Difficult Setup; Poor Interface
