    Fantastic Gen4 SSD with DRAM
    5 out of 5 stars
    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!

      The **WD_BLACK SN850X 4TB SSD** has been an absolute game-changer for my mini PC setup, delivering top-tier performance that exceeds expectations. As an M.2 2280 NVMe SSD with PCIe Gen4 compatibility, it boasts incredible read speeds of up to 7300 MB/s and write speeds of up to 6600 MB/s, making it one of the fastest drives on the market. After installing it in my mini PC, I immediately noticed a massive improvement in load times for games and applications. Games that used to take minutes to load now start almost instantly, providing a seamless and immersive gaming experience.

      To put it to the test, I ran **CrystalDiskMark**, and the results were impressive: **6938.39 MB/s read speed** and **6616.51 MB/s write speed**, which are very close to the advertised speeds. This level of performance is exceptional, especially for a high-capacity 4TB drive. The SSD handles everything I throw at it—whether it’s gaming, multitasking, or transferring large files—with ease and reliability.

      The compact design of the WD_BLACK SN850X makes it perfect for mini PCs, where space is often limited. Despite its small size, it doesn’t compromise on performance or capacity. The 4TB storage is more than enough for my extensive game library, work files, and multimedia projects, eliminating the need for additional drives.

      In conclusion, the **WD_BLACK SN850X 4TB SSD** is a powerhouse of speed, reliability, and capacity. It’s an excellent choice for gamers, content creators, and anyone who demands high performance from their storage solution. I highly recommend it to anyone looking to upgrade their system with a premium SSD that delivers on its promises. A fantastic investment!

      Capacity: 1 TBStyle Name: PCIe 4 M.2 - Heatsink VersionVerified Purchase
      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 easier

      The 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 that

      If you want top-tier performance with excellent thermal control, this drive is worth every penny. Highly recommended!

      The 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 that

      If you want top-tier performance with excellent thermal control, this drive is worth every penny. Highly recommended!

      Absolutely awesome drive, super-fast, super sturdy. Well worth the money.

      I upgraded my system from a 1TB WD_BLACK SN850 I'd managed to fill up.

      I was able to clone my installed 1TB System drive onto this new 2TB one in an enclosure without any issues, then just swapped the drives over and the PC booted right up and Windows didn't even seem to care it was running off a different drive.

      Faster and with more capacity, it's noticeably improved Windows performance. My old drive is now going to be used for the latest games (like Starfield) that require SSD's to run effectively... And of course, Skyrim will go on there... :)

      Delivered promptly.

      I was actually looking for a 2tb and had one in basket already when I came across this WD Nvme.

      I decided to go for this over 2tb to give myself peace of mind.

      The installation is as easy as it can be. WD provided cloning software which after downloading it took about 4 minutes to clone my older Nvme and that's it really!

      It's fast and reliable brand. Downloaded WD dashboard from their website to use T.R.I.M and it works flawlessly.

      Overall happy with the quality and price point of this product.

      Haven't benchmarked it yet but this is next on my to do list over the weekend.

      Picked up the 4TB WD_BLACK SN850X for my gaming rig and it’s been awesome. Install was super easy, and right away I noticed how fast games load—seriously quick. Read and write speeds are as advertised, and everything just runs smoother overall.

      Tons of space too, so I don’t have to constantly delete stuff to make room. Temps have been stable, and performance hasn’t dipped at all even under heavy use.

      If you're into gaming or just want a beast of an SSD, this one’s solid. Definitely worth it.

      Got this for a fantastic price on Prime Day.

      I was not sure how this would behave in an old '2013' Mac Pro (via a cheap tiny adaptor) — some NVME's will part-work, but for some reason MacOS can't boot from them ...no such worries here thankfully!

      I am getting slightly faster — and certainly more consistent — write-speeds with this NVMe storage when compared to the old Apple storage that originally came with my Mac ...and at a decent 1TB it has quadruple the capacity of the old stock apple stick.

      The built-in heat sink seems decent — if you have room for a heatsink I would always opt use one.

      The OS seems slightly 'nippier' to when using this storage.

      I also have Windows 10 on a partition on this stick, and that too seems to run without issue.

      If this goes on 'sale' again (for £75 or less) then I would highly recommend it.

      No throttling due to heat like my original (cheaper) nvme ssd (with no heatsink). 6 month in and so far everything running great and it was super easy to install.

      One of the faster PCIe Gen4 x4 drives on the market.

      Note to self, always it's good to check motherboard specifications before getting a 2nd SSD. I got a bit surprised by the fact that the 2nd M.2 slot on the MB only supports half the speed of the M.2 slot next to the CPU, which means I could've just as well gotten a cheaper drive for that slot.
