Customer Ratings & Reviews

WD SN770M 2TB Internal SSD is a mobile game drive that can be used to expand your handheld gaming device like Asus ROG Ally or Valve Steam Deck. It is also compatible with laptops that house M.2 2230 drives. It is super-fast with read speeds up to 5150 MB/s. Being a 2TB drive helps with storing large library of games locally. I was able to upgrade my Asus ROG Ally easily. It comes with a 512GB drive, which is not enough to store the entire library of games and media. Before you start, make sure your BIOS is updated with the latest firmware using the MyAsus app. You also need a small Phillips screwdriver to remove the screws from the backplate. Once you replace the drive, ROG Ally will boot into the UEFI BIOS mode so you can install Windows 11 from Asus Cloud Recovery. After the upgrade, the boot up time for my ROG Ally is significantly improved. The application and game loading times were blazingly quick. Overall, this is a much-needed upgrade that boosts drive speeds and provides plenty of storage for all your handheld gaming device needs.

This card is a major upgrade to the one that comes provided in my ROG Ally, being four times the size. Being that the Ally comes with a single port for the card, this would be a replacement, not an addition, so if there's anything you want to save, make sure to do so before replacing the card. Card installation is pretty simple, with a single screw after sliding the storage into the slot; it'll likely take longer to remove the back plate of the device you're adding it to. You will need to go through a lengthy process of reinstalling the OS, but, at least with the ROG Ally this card was meant to upgrade, there was an Asus recovery function accessible through the BIOS. After the process, you will have to reinstall some programs and run a number of updates, as it is essentially a fresh device where the dive is concerned. However, with the increased space and speed of the WD-Black SN770M, this process is much quicker (and less battery consuming) than the initial setup of the device. Plus, the design around the device beyond just the increased speeds is the space, and it can definitely hold more games on it, and get them up and running smoother and faster.

Since launch I have absolutely loved my Asus Rog Ally and I take it with me every day no matter where I go! The downside has been the smaller storage size that has really limited my library, and being someone who loves to have a variety of games ready to go I needed something more. I have used several M.2 solid state drives from Western Digital in the past so the WD Black SN770M 2TB seemed like the most obvious choice for a quick upgrade on my Asus ROG Ally. The physical install is simple, I think it took me all of 15 minutes to get my factory SSD out and the WD Black SSD installed into my system. After a quick reinstall of the Operating System I was ready to go! I have dozens of great games now installed on my system that I can take with me everywhere, without having to worry about deleting and reinstalling games all the time due to small storage size! In addition the load times have improved, and the read/write speeds have made transferring files and downloading titles so much quicker! If you need more storage, this is absolutely the way to go!

Snappy. Gorgeous. Easy to install. Another budget banger from Western Digital. I would say top 5 ssd for steam decks or allys considering price to power.
