    Sandisk Extreme SSD Great but Returned

    I have returned two 4 Tb Sandisk Extreme Pros with prolonged transfer speeds of 950 mb/s read/write speeds. Overall product is great, gets hot tho and I was concerned about its longevity. Con was the dmg file necessary to unlock password protection, if you lose the software included in the drive, you will need to purchase another ssd to download dmg, since software can’t be emailed or found on Sandisk’s website. Although I returned the item after upgrading my internal SSD on MPB 14 inch, if large amounts of storage are needed externally Sandisk is the way to go.

    I love this! It is sooo small, light and easy to carry. Very dependable and easy to use. SanDisk is extremely reliable and wouldn't use or trust anything else to store my TONS of irreplicable photos that I have loaded on this tiny device. Thank you, SanDisk! I've been using your products for YEARS :-)

    Works great, less capacity than expected

    Good points: Small (extremely portable). Comes with connectors for both USB-A and USB-C, so it connects to everything. Seems to be fast. Optional whole-disk encryption is very easy to use, keeps private data private. Bought it on sale at about half price, making it an exceptional value. Concern: On Windows, less usable storage than I expected. Explanation: On any device, files have 2 sizes: the actual size, and the amount of disk space they use. On this SSD, files are allocated in multiples of 1MB. So a file of 100 bytes uses 1MB of disk space. A file of 1.001MB uses 2MB of disk space. This wasted space was a problem for me. I replaced a 4TB hard drive with this SSD. With 1.5 million files, the hard drive had nearly 2TB free. The SSD has less than 0.5TB free. The wasted space might not be a problem for you. It depends on how many files you put on the drive.

    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.

    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.

    This 8Tb SSD is an excellent buy, especially if you can find it on sale for $599.00 like I did thanks to Best Buy's Black Friday sale. The drive is fast enough for perfect playback of 4K video without dropping frames, and it's large enough to easily handle enough footage for two or three wildlife documentaries.

    This is by far my favorite external storage device. With 4 TB’s it holds tons of pictures and videos. You don’t have to worry about dropping it as it’s very solid and dependable. Highly recommended. I need to buy more of these as I use them for video editing and holding all those files.

    Lightweight and easy to use. Lots of storage--- better than most drives and seems to work well. Put bit locker on it, but as large as 4tb it took awhile to complete the encryption process. Well worth it.
