    Incorrect File Size, Fills all 4TB SSD with 250GB

    If I could give it 0 stars, I would. Do not buy this SSD if you value your time. I have wasted a whole week trying to copy files into this SSD. It artificially inflates your files and makes a 250 GB file transfer take up ~3 TB. I found other folks reporting this type of issues without any real solution. Likely to be a hardware malfunction. I recommend buying an SSD from a better company like Samsung. I'm returning my SanDisk SSD at this moment.

    No, I would not recommend this to a friend

    The 8TB SSD is an absolute game-changer. Lightning-fast read and write speeds make transferring massive files effortless. With so much storage packed into a compact, durable design, it eliminates the need for juggling multiple drives. Reliable, quiet, and insanely fast—this SSD is a perfect blend of speed and space.

    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 :-)

    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.

    Love this SSD! It is extremely fast and saves my computer tremendous space so it does not lag or bog down. I love the fact that I can plug this in and save all my games to it and it's as if I do not have anything plugged in at all. Very quiet and durable as well.
