    Fantastic performance with maximum storage. I used this to replace my 2TB in PS5, and now I have double the storage, with increased performance faster than my old SSD. I didn't get a heatsink as I don't game that hard, but I highly recommend it if you do.

    Amazing! Got it for my ps5 and it was easy to install. I had to buy a heatsink separately but saved more money that way than purchasing the one marketed for the PS5. Highly recommended simply to make sure all your favorite games are ready to go whenever you wish.

    Not only are the speeds of this drive insane but at 4TB of storage it also feels like you always have space for more games. Also considering it's meant to be a $520 Firecuda 530 competitor it comes in at a decent price point for what it is.

    I've been using the SN850X SSD for a while now, and it's been a game-changer for my setup. Games load incredibly fast, and I've noticed a huge improvement in performance. It's also great for multitasking and handling large files without any lag. The only downsides are that it's a bit pricey and doesn't come with a heatsink, which might be necessary for some systems. Overall, it's a fantastic SSD for gamers.

    With 7 Gigabyte write and 7 Gigabyte read speeds it is amazing. Make sure your cpu and m.2 port supports the 7 Gigabyte speeds, but if it does WOW. Even with a good heat sink the temp get's in the 80 degree C range, so make sure you add a good heat sink to go with it.
