Prime Day SSD offerings were always going to be a big player this summer. And 'big' is the keyword here: right now you can get some absolutely massive SSDs for a fraction of their retail prices. While it might feel hard to get a cheap SSD deal at the best of times, these portable SSD Prime Day deals feature heavily slashed prices on some monster drives, making them a lot more affordable.

Because these SSDs have the versatility of being portable, you can use them for a number of different applications. Attach one to your PC or Mac and you'll have more than enough space for even the most extensive game, music, and video libraries, while attaching one to your PS5 or Xbox Series X means you can download all the games in your collection and have them ready to play directly or quickly transfer to the internal drive as required. If you're planning to upgrade your console then make sure you check out all the other Prime Day PS5 deals and Prime Day Xbox Series X deals available.

Kicking things off we have the SanDisk Extreme Pro 2TB Portable NVMe SSD, which offers speeds of up to 2000MB/s read and write speeds and has been reduced from £428.99 down to £269.99 (opens in new tab). With this you'll also get a drive that is housed in a case that can protect during drops of up to 2 meters and is both water and dust-resistant, meaning your data is safe in all but the most extreme of circumstances.

Next up we have the WD My Passport 4TB Portable NVMe SSD, which has a similarly massive £311 discount this Prime Day to reduce it from £745.99 to just £434.99 (opens in new tab). With comparably fast 1050MB/s read and 1000MB/s write speeds it's certainly no slouch, while the sleek Space Grey metal case not only looks stylish but provides shock and vibration resistance plus drop protection up to 2 meters.

Finally, there's the WD_Black P50 4TB Portable NVMe SSD, which is specifically aimed at gamers and commands a somewhat higher price tag, being reduced from £857.99 to £599.99 (opens in new tab) and saving you £258. There is a good reason for this additional cost, however, as it offers blisteringly rapid transfer speeds of up to 2000MB/s, making it almost twice as fast as the other 4TB drives on offer here. You also get a forged aluminium cover with this one, making it shock-resistant as you transport your games around.

Don't forget that although these are all SSDs, you (currently) won't be able to run PS5 or Xbox Series X games from them directly as these can only be played from the internal SSD. However, both consoles allow you to store your new-gen games on an external drive to free up space internally, and if you pick one of these portable SSDs then the super fast transfer speeds mean you'll be able to move your games around to where they're needed in no time.
