Fast
||Posted . Owned for 11 months when reviewed.Easy Install and Easy to set up. My hdd has had a lot of stress on it so I order this ssd I put it is and transfer some of my big files on it and it ran with ease. My compute has ran much faster and crashs almost never happen.

PS5 upgrade
||Posted . Owned for less than 1 week when reviewed.Picked this up to upgrade my PS5, and I'm am very happy with my purchase. You do have to get a 3rd party heatsink, but you can find a quality one on amazon for 12-20 bucks. I got it through the black Friday sale so between that and the heatsink I came out spending 80 bucks less than the same version of this ssd with the integrated heatsink. Since the PS5 requires a gen 4 ssd options are a little limited, but this should be one of your tip choices.

Great SSD for PS5
||Posted . Owned for less than 1 week when reviewed.Decided to get this over the Samsung 980 pro due to reports that you needed to update Samsung in a PC to unlock higher speeds. Paired the WD Black SN850 1TB with a basic low profile heatsink to fit in the PS5. Works perfectly and has a read speed over 6500. Plays PS5 games perfectly and transfer games so quickly. Very happy with my decision.

Excellent drive if you need the speed.
||Posted . Owned for 3 weeks when reviewed.Wickedly fast. If you have a system that fully supports PCIe 4.0 and run applications that require fast read/write, you can't find a better option. It can get hot as many other reviewers noted, but so far with a motherboard-supplied heatsink I haven't had any throttling issue. My processing times are more than halved after switching.

Q: Questiondoes it work with ps5?
Asked by Anonymous.
- A:Answer Yes, this will work with PS5. You should install an aftermarket heatsink as recommended by Sony, but it is compatible.

Q: QuestionWill this work with a pcle 4*16 lane expansion slot
Asked by Electro.
- A:Answer Hello Electro, Please be informed that the WD_BLACK SN850 SSD comes in two variants with heatsink. Long load times are obsolete with next-gen PCIe Gen4 technology, reaching irrational read/write speeds up to 7000/5300MB/s**. Arm your system with RGB lighting, an optional heatsink model. Please check with the PC/Laptop vendor whether the WD drive will fit and support the host device.

Q: QuestionHi, would you please tell me if this memory its compatible with the HP - Victus 15.6" Gaming Laptop - Intel Core i7-12650H - 16GB Memory - NVIDIA GeForce RTX 3050 Ti - 512GB SSD - Mica Silver that you sell?
Asked by Mary.
- A:Answer It should be compatible so long as you have another nvme slot available in your laptop. As the 12th gen supports PCIE gen 4 and should have enough PCIE lanes to run 2 ssd and a gpu on it from the cpu.
Answered by Nathan
Q: QuestionDoes this PCIe GEN 4 stick work in any new laptop? i have the ROG Strix advantage 2021 (all AMD) and i am looking to upgrade the SSD and i am concerned that AMD isnt compatible with GEN4s. Will this work or do i need a GEN3? thank you
Asked by pete.
- A:Answer I’m not an expert by any means but I run AMD and have no issues. Just make sure your NVMe slot is 4th compatible otherwise you won’t notice the capable speeds of the drive.

Q: QuestionIS WDBAUY0010BNC and WDS100T1X0E exactly the same other than the pre-installed software? So WDBAUY0010BNC would work the same in a PS5 and would not need installed software? Thanks!
Asked by WDBLACK.
- A:Answer Works for me but shows an invalid product at WD. You will need to initialize this and add a simple volume.
