    High end nvme for gaming needs

    Excellent price for a high end nvme. I got this for my gaming laptop and it performed well. Specs is right up there with the best of the best. I was also able to get it during the sale and got it for pretty low price right before the new year. Prices for ssd are excepted to drop, but for now I should be good for plenty of games on my gaming laptop. Speed is very fast. See picture of the crystalmark. Definitely not the fastest at sequential, but the IOPs is out of this world and that is what really matters when you are doing a lot of small random files. I highly recommend this for anyone who wants the best right now for a reasonable price. My only gripe is this is a 2 sided nvme meaning there are flash chips on both sides of the board. This might not be a big issue for some but for me, it made the chip a bit chunky. I compensated on my laptop by not screwing it too tightly and use light threadlocker to prevent the screw from coming loose.

    Okay, there is not much to review. Just pop them into your Gen 4 slot (Gen 3 will work but be slower) and away you go. It is super easy and if you have to force it, it may not be the right type. These things are rockets even compared to your SATA connected SSDs. It made more of a difference in speed on my system than did 64GB of RAM, or a top of the line Intel I9. This is the best upgrade you can put in your system as hard drives are a choke point for data. I recommend a small drive for your OS drive. 500GB will suffice in most cases even if you have a lot of apps but I went with a 1TB because that was the smallest I could get. I then put in two 4TB drives for DATA storage. The reason you want to keep the OS drive small is so you can make backups on the DATA drive. You can partition the large one down for the OS drive but be careful restoring the OS. If your system supports Gen 4 or Gen 3 these are a great option for speed!

    I used to have a laptop with an SSD for the operating system and an HDD for the rest of my data and applications. After trying this SSD for my new computer and having all my things in it, I don't think I can ever go back. The speed at which my computer operates is significantly faster than before, and it has good quality overall. I definitely recommend this product if you are able to afford it, it is worth the price.

    I bought 3 of these, a 1 tb, 2 tb, and 4 tb. They work great and hold all my games. I'm no better at said videogames, given the quickness of these m.2s, but I'd like to think I am. Regardless it's a great product, and western digital has yet to dissapoint

    I put this in my Asus ROG Ally X, which was crazy easy to do, and it works great, everything loads super fast. There is a guide from Asus how to change your ssd and do a cloud recovery. I did the upgrade before I even used the device and it took awhile and requires wifi but in the end it started up like the ssd had always been there, no cloning required (I have no idea how to clone anything).

    Great SSD with lots of space for my PC. 2 years ago you could only get a 2TB PCIe Gen 4 SSD for this price. Now I have plenty of space to install games with faster loading times.

    Was between this and firecuda. Could not find exact read speed for either with 4tb. I ended up choosing this because could get sooner and cheaper. I am glad i did. I couldnt find exact speed online for 4tb anywhere with ps5 but i got 6504 mb/s with lanch version ps5.

    I have looked into compatible m.2 and i looked at this WD as a end all solution. First day in the thing says overheating. I am testing it out with data backup and heavy play. Wish to edit until further notice. Shoudl this be paired with a heat sink?

    so far it has been excellent. REALLY fast, doesn't run hot in my PC, and all the storage I could want. It's has twice the storage capacity and 90% of the advertised speed of the Samsung 990 (actually a bit faster than the 990 on mixed read/ write), and no widespread failure issues.

    Fast and sleek 4TB internal SSD! Fairly priced too! Every PS5 owner must own one of these guys! Recommend getting it from Best Buy because of the warranty they offer. It’s a super easy install, keeps the system running smooth and it is great for storing all those DIGITAL GAMES!!! Don’t forget to get the cooling cover, it can also be purchased along with the ssd for a low price through BB! It’s just as described and shown!
