    I keep this SSD plugged in to my MacBook Pro 14" M1 as my 'portable' Photo library (vs using the internal SSD) and after reading a few reviews about latency issues with some of the SanDisk SSDs that other users attempted to use for these kinds of dynamic applications I had some concerns but for my

    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.

    Okay, so I got this SanDisk 4TB portable SSD and it's pretty awesome. First off, it's really small and sleek, which I love. It's black, looks cool, and feels sturdy enough that I'm not worried about it getting banged up in my bag. The best part? This thing is fast. Like, really fast. I've been moving huge files around and it doesn’t even blink. It's got a ton of space too – 4TB is more than enough for all my stuff. I've got loads of photos and videos and there's still plenty of room left. Hooking it up is a breeze. It comes with a USB-C thingy and it worked straight away with my laptop and even my phone. Didn’t need to mess around with any settings or software, which is a huge plus for me. About the price, yeah, it’s not cheap, but you're getting a lot of storage and the speed is worth it, in my opinion. In short, if you need a lot of storage on the go and hate waiting for files to transfer, this SanDisk SSD is a solid buy. I’m pretty happy with it.

    I loveee this hard drive! As a photographer I needed something that was beefy, and this thing is it! I went from a Lacie, and the difference in size alone is crazy. This one is so much smaller, and quicker! I was shocked how small it was. Perfect for transporting!

    This thing is amazing. I use it to store all of my reports and technical manuals email backups schedules. But then at the same time i have starfield wow and ark on it and i can run them directly off of it without running down my storage. Plus I never have to carry a computer bag. I just pop it in at work and bring it back home and boom i can pick up where i left off.
