5.0 out of 5 stars Wonderful surprise
I purchased this mainly for it's reported compatability with a particular router. I did not pay much attention to the description. The drive has far surpassed my expectatons.

1.0 out of 5 stars On its way back
I wanted a SanDisk flash drive with a good feature set and capacity but I will continue my quest as this one is headed back for a refund.

The 64 gig flash drive works OK on my Vista Ultimate desktop, but it has the 2-drive display issues (where the flash drive will appear twice under 2 drive letters).

This review is from: SanDisk Ultra Backup 64 GB USB 2.0 Flash Drive SDCZ40-064G-A11 (Electronics)
I purchased this mainly for it's reported compatability with a particular router. I did not pay much attention to the description. The drive has far surpassed my expectatons. It not only works well with all of my equipment, it does much more. The backup function was the best surprise. Any time I want to backup I just push the button on the drive and go back to whatever I was doing. It works in the background and I never notice it slowing other processes I am using. I don't remember ever writing a review before, but this product definitely deserves KUDOS. Some may think it a bit pricey but it is actually very competitive or cheaper than other 64 gb drives. If you need a flash drive this size, you will not find better. When I need another flash drive, I know what I will be buying. By the way, Amazon had it to me in a few days even though I selected the free delivery option. Thanks to Amazon for years of snag-free orders.

Using Windows 7 is the real deal-breaker, as the Launchpad will not launch. Period. If you are using Windows 7 as your OS, check the interwebs for issues with the U3 system/Launchpad before you buy this unit.

3.0 out of 5 stars Works intermittently beyond 7GB's, March 4, 2010

This review is from: SanDisk Ultra Backup 64 GB USB 2.0 Flash Drive SDCZ40-064G-A11 (Electronics)
I didn't buy this flash drive to use 'U2' or for the 'Back-up' feature so I used SanDisk's U2 removal tool and then re-formatted the flash drive to NTSF. SanDisk said that should be fine. After I copied over 7 GB's of data to the drive, I noticed some strange behavior when copying some additional files. Certain files would appear to have been copied but no file size or date would show up for those files, just the file name would be in the directory. I gave it 3 stars out of the benefit of doubt that it may have been good for FAT32 use. I returned the drive and decided to go with a larger 128GB Patriot instead, since the price with rebate on Amazon was pretty good.

1.0 out of 5 stars Total Failure, December 12, 2009

I tried TWO of these Sandisk Ultra Backup 64 GB.

When the first one did not work, the store was kind enough to send me a second one.

Both failed dramatically so there were returned to the store to get my money back.

The idea is good, but it does NOT work as expected.

Besides, to backup just 20 Gb of material, took about 14 HOURS! I do believe we have better technology than that.

I purchased this to backup specific project data when I am traveling on business. It completely fills my needs. I have not used the auto back up feature as my data resides in non-standard directories, so I can not comment on that.
Good value, form factor and price.

This review is from: SanDisk Ultra Backup 64 GB USB 2.0 Flash Drive SDCZ40-064G-A11 (Electronics)
I bought this drive to backup my Photo, Music and other document files. The idea is that this type of solid-state-no-moving-parts backup is less apt to fail.

This Flash drive has several Backup options and configurations and also the Backup Button. I inserted the Drive and it was simple to configure. The backup software backed up 16 GB in about 1.5 hours. You can watch the files as they back up and the list scrolls down. This comes to an end, stops and works great.

The problem I have is that the subsequent backups DO backup the files (I set the Date), but the backup software DOES NOT stop or end. I have to stop the backup, close the software and exit the drive. The button DOES start the backup. The software has to be MANUALLY closed. This is not a big problem but is annoying.

A comment I sent at the SanDisk website did get a response, but it was to use the live backup mode. I responded with all my settings, and told them I want to insert the drive each backup. They said they would get back to me.

The SanDisk website support is poor after the initial setup and use instructions.

The SanDisk website price is WAY TOO HIGH.

I do like this drive. The Amazon price was the lowest. The backup button does work. The backup does happen. I just would like the software to stop. I have a WinXP SP3 2.0 GHz Home PC.

I recommend this product to anyone who has lots of different documents. The device is very easy to use, and it makes backup very fast. One negative feature I notice is that the software pre-installed was only for WinXP and Vista. I have Win7 so I have to Update it from WinXP running computer. It could be easier.. but I think the manufacturer would install the Win7 compatibile software in new drives.

Great Flash Drive.

I could find only one thing bad about this product, the backup feature will not work with Windows 7 x64. However, this does not matter to me, for I purchased this for the capacity.

I really do believe in the integrity of Sandisk and this product is no different. It has a very fast backup capability. Great also for general storage.
