    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.

    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.

    Of course looks shouldnt matter when it comes to storage options but you gotta admit this sky blue is a good look. No problems with the drive’s functionality. Transfers files fast and has so far been reliable.

    Solid product, been looking forward to the increased storage in this series. Not too much larger than my 2GB model but double the storage! Durable, sturdy, solid. 9.5 / 10
