Fantastic Gen4 SSD with DRAM

I bought the 4TB ver when it was on sale for £208, and at that price, it's hands-down the best Gen 4 SSD deal you could ask for. Its reputation for top-tier performance, quality build, and solid reliability is well documented over the years. I bought mine specifically for demanding tasks, a mix of heavy workloads, gaming, and general everyday computing.Even at its usual price, the SN850X is right up there with the best Gen 4 drives that include DRAM, like the Samsung 990 Pro and Crucial T500. It strikes a great balance: more affordable than the 990 Pro with performance that feels very similar in day-to-day use, while offering better sustained write speeds under heavy load compared to the T500, which is a plus for large file transfers or content creation.For console use, it's the same, a top tier choice, keep in mind you will need a heatsink for it if that's your usage, either a third party or official one (more expensive). However, if you're a budget gamer, you'd be just fine with a cheaper DRAM-less SSD.Just a heads-up, the actual usable space you get after formatting is about 3.6TB. This is normal for SSDs due to space reserved for performance and longevity (over-provisioning).Getting this drive for £208 was a no-brainer for a top-end, high-capacity SSD with DRAM. If you need speed for demanding applications and gaming, and especially if you see it near that sale price, grab it. Highly recommended!

Blazing Fast and Runs Cool — Perfect for Gaming

I upgraded to the WD Black SN850X 1TB with Heatsink for my gaming pc after my ssd died, and it has exceeded every expectation. Installation was a breeze — it slotted perfectly into my motherboard's M.2 slot, and the built-in heatsink saved me the hassle of having to reuse the one i already had and made installing it easierThe speed is incredible. Boot times are almost instant, and games load fast AF. I’ve also noticed smoother performance although thats probably due to having a fresh windows install. The heatsink does a fantastic job — even under heavy load, temps stay well within safe limits.It’s also PlayStation 5 compatible, so this would be a great option if you're looking to expand your PS5 storage with something fast and reliable. although i dont own one so cant comment on anything about thatIf you want top-tier performance with excellent thermal control, this drive is worth every penny. Highly recommended!

Excellent drive - the heatsink makes a real difference!

My first M.2 SSD was the 1TB SN850X, and after 1.5 years of gaming on it (using the motherboard’s heatsink), I was so happy with the performance that I decided to get another, this time the 2TB version with the built-in heatsink.Tested both in the same M.2 slot and conditions - the 2TB without heatsink hit 85°C under load, while the one with the heatsink peaked at 65°C. That’s a massive 20°C drop just from the heatsink alone. Idle stays around 40–42°C. No need to mess with pads or third-party coolers. Just plug it in and you’re done.If you’re planning to push the drive or want peace of mind long-term, get the heatsink version. Totally worth it.

Not difficult

A small Philips screw driver is required for Play station Ps5 fitting is fairly straightforward to ps5 watch you tube videos for basics.Once installed and everything is secured, switch on and on screen it comes up (ps5)Format drive which you select and takes less than a minute to do soYou can transfer games across, go to settings etc, but cheat go to you tube to be shown what to do.Have transfered two games and appears to be OK.

Highly reputable brand

The WD_BLACK nvme drives are highly regarded. I purchased 3 of them (as one of the purchases came with no drive which seems to have happened quite a bit from the Amazon reviews I read). The price of these drives are about average but due to their reputation it definitely gives you peace of mind as a purchased a Lexar NM790 4TB SSD previously which failed within a day.

Good choice

Actually works as advertised no issues as of yet and that's still going well today

Fast and reliable SSD, but you probably don't need it.

If you have a lot of workloads involving video encoding/decoding, compression/decompression or transfer lots of large files around, then this SSD is worth it, otherwise, you probably don't need it.This SSD is pretty fast, the results speak for themselves, the one I received seems to be below the advertised read and write speeds, but this may be due to the software I used to measure the disk speeds. I recommend looking up benchmarks for the drive online by capacity, as the drive performance can vary across capacities. To get the full speed out of this drive, you will need at least a PCIe 4.0 4x slot. In terms of boot times, you won't notice the difference between this and any other half-decent NVMe SSD, I find that my motherboard boot sequence is the limiting factor rather than my OS, this may be different if you use Windows. I find that in general usage, I cannot tell the difference between this SN850x and the SN570.In terms of durability these drives are rated for 600TBW per Terabyte of capacity. If you are using it as a storage drive, and write 100GB of data every day to it, it would take you roughly 16 years to reach the endurance rating of the 1TB drive.Heatsinks are generally recommended to reduce the chance the drive throttles its performance, so if your motherboard doesn't come with its own NVMe heatsinks, it may be a good idea to get the SN850x version that comes with one, provided it is compatible with your motherboard and the device the motherboard is a part of.To summarise, you probably don't need this drive, the WD Blue SSDs such as the SN570 are probably good enough. However if you are worried about drive durability or have workloads that will incur heavy I/O loads, then I can recommend this SSD.
