    They seem to make them smaller and smaller these days. This is an excellent little storage device. I always recommend buying them when they go on sale of course

    This thing is amazing, the only issue is how small it is. Make sure you but a leash on it.

    A perfect thumbdrive

    Overall, I like this device. It has a few extra features that I am not sure how they fit into my life but it is not required. I will discuss more below. Unboxing: The device is pretty simple. It has the USB drive, a voucher for the flashback software and a voucher for RescuePRO software. Build quality: Pretty good! This is the 128 GB model. I went for this one since it has USB 3.1 support for higher speeds. The device is extremely tiny and will be great if you leave it plugged into a laptop as it does not protrude too much. The design has a curved indentation that is functional at the end, for one it provides a little extra grip to grab it when pulling it out, second it has a hole in it so you can connect it to a lanyard / keychain. Performance: It has plenty of storage space at 128 GB (a little less available). I ran Crystal Disk benchmark on it and got read speeds of 134.6 MB/s read and 51.7 MB/a write. This speed is actually BETTER than what is advertised on the website (130 MB/s). In transferring a 3.3 GB file I got between 130 – 140 MB/s read and between 35 – 70 MB/s write. It looks like it had a burst speed for the first third then slowed down to the lower speeds. Features: It is mostly just a great performing small thumb drive! But... Sandisk tossed in a few goodies with it. First it has the usual SanDiskSecureAccess software. This is pretty basic software but it allows you to password secure files on the thumb drive that are encrypted and unrecoverable if your drive is lost. Second, it comes with a new software called SanDisk Flashback. To use this, you will need to install the software on your PC / Mac. It works very seamlessly and works similar to drop box/OneDrive/etc. When you log into the website, you will see any photos and files on your home screen. The interface is nice and seems to prioritize photos. There is a tab for “devices” which will let you see all of your drives that support the feature. Here is where it gets cool. If you uploaded a non-encrypted filed (not in the vault software) to the thumb drive, it will also upload a copy to Flashback which will allow you to download any files on your thumb drive / cloud to any computer that you access the website from. I have yet to fully integrate this into my work flow but I see a lot of potential for this. Similar to other cloud storage, you can also share links to your files. At first I asked myself “why do I need this? I have Dropbox and upload things to the cloud already”. The advantage of this drive appears to me that you can leave your drive in your laptop permanently expanding storage and always having a local version installed and no longer needing to bring it with me when needed. I know Dropbox and other cloud drives can store local files but this one keeps the storage separate from the main drive. You also have the added ability to take the drive with you if you wish for faster transfers to computers that might not have download speeds needed for a file. In short, it gives you options. Summary: Pros: -Convenient -Compact -Very fast! Cons: -Features possibly redundant -Easy to lose! -No phone app as of yet, only PC and Mac Some users will think this is redundant, especially since it costs a few bucks after the first-year trial (to be fair it is dirt cheap, my 128GB will cost $4.99 a YEAR, not month when my trial is over). For others, you might be able to find some very good use out of this ability. I personally think it is slightly redundant, but it is also extremely convenient and allows me to separate certain types of files for a much cheaper price than cloud options. For example, Google drive costs $19.99 per YEAR, this device will only charge $4.99 per YEAR for 128GB, you will save even more if you get a 256GB model. I can’t really find any faults in this feature and in the thumb drive. Used properly, you might be able to replace your cloud storage!

    This product does just what you would expect it to do. It’s great. It sticks out a little farther than I would like but what are you going to do?
