4 out of 5 eggsAll Flash Drives Should Have Password

This review is from: SanDisk Ultra Backup 64GB Flash Drive (USB 2.0 Portable) AES Encryption Model SDCZ40-064G-A46

Pros: Waited almost 2 months before giving a review. Works as expected. Easy to use even for non-techy people. Good product.

Cons: Plastic - Feels Filmsy, Too Large For Keychain,

Other Thoughts: I would rec this product. Works as stated. I wish this flash drive was the size of my mini 4GM flash. I also wish it was made out of metal like my mini flash. Don't like flimsy plastic housing. Flash is lightweight, but too large for your keychain. Keychain hole too small too. All flash drives should be password protected. Only reason I purchased was because of 64 GB size with encryption.

5 out of 5 eggsWorks fine

This review is from: SanDisk Ultra Backup 64GB Flash Drive (USB 2.0 Portable) AES Encryption Model SDCZ40-064G-A46

Pros: Cheap 64gb flash drive
Sandisk brand name

Cons: pre-loaded software
useless backup button

Other Thoughts: I bought this as a regular flash drive, not as a backup drive and it works perfectly for that. First thing I did was format the drive.

I use about 8 of the 64GB Patriot Magnum drives in my business, but this one is a good bit cheaper and so far is working great. Can't comment accurately on copy speed, haven't run any tests, but seems to be about as fast as the Patriots if I recall correctly. (~8-10 MB/s)

It's still USB 2.0, so copy speed is pretty bad no matter how you look at it. Get a fast USB 3.0 drive if you want quick copy speed.

This review is from: SanDisk Ultra Backup 64GB Flash Drive (USB 2.0 Portable) AES Encryption Model SDCZ40-064G-A46

Pros: None - we ordered 3 of these and the first one out of the box failed...no instructions came with the stick...did auto install online..it took 2.5 hours to sit and spin saying "please wait while processing" and then a fatal error message popped up.

Cons: Called for tech support..got a nice woman in UK who sent me an email request for a screen capture, op system, & brower used. I answered right away and have yet to get a response from YuuWaa. Guess we will be returning all 3 and buying something else. Given these were $90 each and had good ratings we are very dissappointed.

1 out of 5 eggsBUYER BEWARE

This review is from: SanDisk Ultra Backup 64GB Flash Drive (USB 2.0 Portable) AES Encryption Model SDCZ40-064G-A46

Pros: The origional drive was great (purchased 12 mo ago)

Cons: The new drive purchased a week ago (same SanDisk part number) is not the same drive. Original drive worked with U3, newer drive does not. I talked to SanDisk Tech Support and was given the "That's to Bad" song without any solution. BUYER BEWARE, SanDisk changes the functionality of there products without changing part numbers or descriptions.

Other Thoughts: I definately will be looking at other manufacturers BEFORE I purchase another SanDisk product.

5 out of 5 eggsGood so far

This review is from: SanDisk Ultra Backup 64GB Flash Drive (USB 2.0 Portable) AES Encryption Model SDCZ40-064G-A46

Pros: So far so good. I didn't want or care about the "backup" software so I formatted it out of the box. I don't know what that other reviewer was talking about; it formatted perfectly with NTFS in one partition. As stated formatted capacity is 59.6GB (don't blame Sandisk, this is a result of block size and stuff tied back to formatting hard drives). I put 45 Gig worth of MP3 files on it and use it everyday. I'm digging it...

Cons: NOT an issue with this drive, however know that these things can die whenever they want. I had an 8G from Sandisk that just gave up one day out of the blue. I backup my data (you do too, right?) so it wasn't a big deal. I also have another 8G Sandisk thats been through the washer and dryer and it works perfectly.

Other Thoughts: Now I want a 128G drive...

2 out of 5 eggsVery Curious

This review is from: SanDisk Ultra Backup 64GB Flash Drive (USB 2.0 Portable) AES Encryption Model SDCZ40-064G-A46

Pros: Bought this for my wife to easily back-up her lap top, promised simplicity a big plus.
Storage capacity is as advertised

Cons: Press the device button for back-up did not work. No instructions apart from press the button so ignored the icon on the desk top for a while. Then, after tiring of pressing the button, opened the icon and launched the back-up program for "Documents" which worked.
Tried to back-up other files only to find that the back-up program had disappeared. Tried to download, no site connection for program down loads.
Accessed the Scandisk support site and found faq for download program: answer "The answer to this question is no longer available". Scandisk obviously in a considerable state of muddle.
The product is not what I expected. RMA

Other Thoughts: Had believed that the back-up program would be able to create a disk image to enable complete hard drive restoration. From my brief encounter with the back-up program, I now doubt that it (if it ever resurfaces) has that capability. If this is the case then, as one reviewer has opined, the program is of very limited utility.
