Pros: This drive is insanely fast. My bottlenecks are no longer retrieving data from a drive but now CPU and video card influencing. This drive will work in PCI 3.0 slot but it's speed will be reduced as advertised. In PCI 4.0 slot, it will certainly perform at rated speeds. Transferring large amounts of data feels nearly instant with this thing.

Cons: Not a con for this module. Just be sure your motherboard supports this drive and pay attention to what other components share the same bus. For example, some motherboards may disable certain SATA ports if you consume your PCI slot. Other factors to consider: This device will not take advantage of PCI 4.0 for Intel fans. You'll need to upgrade to an 11th gen processor. If you're an AMD fan, make sure you install with the correctly supported chipset.

Overall Review: Currently one of the fastest solid state drives on the planet.

Pros: Fast Reached advertised speeds

Cons: Didn't play nice with my motherboard

Overall Review: When i did my build the prices on the PCIE 4 drives were crazy high so I went with an M.2 Gen. 3 drive which has worked without issue. When the prices started coming down I picked up this drive on promo. It works great and at advertised speeds when it is up and running. I didn't expect a major noticeable difference but there is definitely a snappier feel compared to my 3x drive. The problem is the drive frequently but not always is not recognized on the initial boot requiring a second and maybe a third boot to to get going. Although most everyone here is happy with their drive, an online search revealed this problem to be common. WD was not helpful with their boilerplate support response. So 5 star performance but a drives gotta boot. MSI X570 GAMING EDGE WIFI RYZEN 7 3800X

Pros: Fits into PS5 perfectly Improves performance (games loaded slightly faster when moved over to this M.2)

Cons: Expensive

Overall Review: Would definitely recommend, but it is expensive and remember that if getting this for PS5 you need to have the Beta 2.0 update, until Sony release the M.2 capability into the mainstream OS.

Pros: Fast Very Fast

Cons: Still premium price

Overall Review: Initially I was going to buy an SSD. Then I decided to get an M.2. Then I saw this and on a whim change from the 3.0 to this one. This is like going from HDD to SSD in terms of speed over SSDs. (Well maybe not that much but it is much much faster) Western Digital doesn't disappoint. (I still have 6 750 GB WD Blacks in a RAID that has been running 24x7 for 10 years with no failures.) Idea on speeds it takes Windows 10 longer to copy the WIM file from a USB 3.0 stick than it does to actually do the install. You better have the latest MB with 4.0 support and a current gen processor (AMD Ryzen 3rd gen) to take full advantage of this. I'm getting ready to buy a second one to RAID them.

Pros: Super easy to install in PS5.

Cons: None

Overall Review: This SSD is little pricey but is totally worth it so dont have to keep deleting games and reinstalling since it takes up so much time to reinstall games. I would definitely recommend this to everyone as it works flawlessly with the PS5 and can only assume it does on a PC too.

Pros: Fast. Small. Its from WD.

Cons: Doesnt install itself. I had a firmware update for my drive. Not really a con, but it could be an issue for someone without something to update the drive.

Overall Review: Bought this drive to expand my PS5 storage. Combined this with the be quiet mc1 (non pro) heatsink and it fits perfectly. The 1TB module is single sided. As noted in the cons, I did have to update the drives firmware out of the box. Apparently it fixed some potential performance issues. Just something to keep in mind if you cant access a computer with an m.2 slot. Im not sure if you can buy a USB adapter to update it.. I could be wrong though.
