Western Digital rarely reveals much about its controllers, and that's the case once again here. The drive itself is a low-profile affair, with this 1TB model boasting a single NAND flash module at the back (actually a rebranded Kioxia BiCS5 112-Layer TLC chip) and the SanDisk controller towards the connector. Such drives are slower, don't get me wrong, but this new SN770 still quotes read and writes of 5,150MB/s and 4,900MB/s respectively. This saves a big chunk of the manufacturer's bill of materials, and thanks to advances in the latest controllers, it can be surprising how little impact this has on performance. The main way it achieves this is by being a DRAM-less SSD drive. The WD_Black SN770 bucks this trend and like its predecessor, the SN750, is aimed at offering better value for money than outright performance. We've seen some incredible NVMe SSD releases recently, but they've tended to focus on top-end performance and come with prices to match.

Read our full Western Digital WD SN850 review (opens in new tab). It's simply the best drive you can buy today. Neither is a bad drive, obviously, but if we had to recommend a next-gen SSD right now, there's only one clear option, and that's the WD SN850. The SN850 builds on Western Digital's previous SSDs to stand head and shoulders above the others to be the performance drive you want in your gaming PC. The Samsung 980 Pro, which had the edge for a few months, is left out in the cold, especially as it costs the same as the SN850, but loses out to the newer drive in every metric (apart from operating temperatures). When plenty of 'fast' SSDs still take 12 seconds to complete the same task, that proves what difference the latest technology can have on gaming performance. The fact that this performance is echoed in the Final Fantasy XIV benchmark, which has the SN850 loading the five different scenes in a shade under seven seconds for the first time, impresses no end. With an overall throughput of nearly 495MB/s in the Quick test and 550MB/s in the Full benchmark, this is a drive that just keeps powering on in day to day use. It's the real-world performance tests that impress the most though, with PCMark 10's Quick and Full storage tests putting the SN850 way ahead of the field.

The 4K write performance in AS SSD manage to flip this over as well, with the WD SN850 managing to outpace the Sabrent drive. Writes are lower than the Sabrent Rocket 4 Plus, but still healthy, at either side of 5GB/s. The synthetic benchmarks, spearheaded by ATTO and AS SSD, show that this is very much a second-generation PCIe 4.0 drive, with peak sequential read speeds knocking on 6,750MB/s and 5,920MB/s respectively.

Don't get me wrong, it does well across the synthetic benchmarks, topping plenty of them, but there are a few places where the Sabrent Rocket 4 Plus or the Samsung 980 Pro have the edge, but overall that doesn't take away from the fact that this is the pinnacle of storage right now.Īny SSD is ultimately defined by its performance and it's here that the WD SN850 really stands out from the crowd. It may not top every test in every benchmark, but when it comes to real-world benchmarking, there's nothing else that can touch it.

The WD Black SN850 1TB drive is the fastest PCIe 4.0 NVMe SSD you can buy right now. And remember, larger drives perform better thanks to more controller channels being used at higher capacities, so buy a big a drive if you can. Each drive we've looked at is available in a range of capacities with prices to match. We've tested loads of NVMe SSDs recently to find the very best options out there. As long as you have an M.2 slot on your motherboard, NVMe is the place to be. A speedy 1TB NVMe SSD might only set you back $120, which isn't much more than you'd pay for a clunky old SATA SSD. Thankfully, the SSD market is fierce right now, so great deals on quality SSDs are not uncommon. What that means, is storage is about to get a lot more important for gaming PCs.

Even modern consoles are touting some of the best NVMe SSDs-both the Xbox Series X (opens in new tab) and PlayStation 5 (opens in new tab) boast speedy NVMe SSDs and you don't want to get left behind by the consoles now, do you? The technology that makes the most of the Xbox's storage (DirectStorage) will be finding its way onto our systems soon.
