    This is a fast little device. Just keep in mind that you have to unsave your password to save the annoyance of signing in every time you power up your computer. Otherwise, the device will be locked until you enter the password.

    I loved theses SSD's! This is my 3rd one that I personally own and I back up alot of photos and videos every month. Fast, reliable and also very small to carry with me especially when I travel for my business. I have the best peace of mind knowing that my clients photos and videos are safe

    Works great -- easy and quick to use when I needed to transfer all the data from a failing PC. I captured everything I needed/wanted with no problems. Since then, I've purchased a second drive -- to have on hand for data storage. Easy to carry with me.

    Drive works as expected. Size is perfect. Speed is great. The cord that comes with it is extremely short. Other than that, there are no issues. I will buy this one again!

    Sandisk Extreme Portable 4 TB SSD

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    So far, the SSD is working OK, I decided it was too large to test with Verification utility so I will trust BestBuy that it is authentic. The supplied cable is just a tad over 6 inches which I feel is too short, would have suited me better if it were at least 12 inches.

    I am very happy with this SSD so far. It is very small and light, works as advertised, and the price was more than fair, enabling me to increase the space of my Time Machine backup to 4TB from my previous 2TB. Long-term experience is yet to be had.

    Beast of a device in a compact size

    If someone asks me which one to chose if they need an external hard drive, i would first suggest the Sandisk external SSD. The device is almost the size of a credit card and the time it took to backup my 3tb of hard disk data is 150 mins at a write speed of around 1/2 gbps.

    Super short useless cable . Decent speeds around a steady 750MBs. Not quite as fast as the Samsung t7 shield my experience. The drive is tiny physical size the portability is high . The price was good while on sale other wise too expensive while comparing it to a Samsung t7 shield.
