WD_BLACK SN770 1TB M.2 2280 Game Drive PCIe Gen4 NVMe up to 5150 MB/s

Product Information

If the SN770 has a weakness, it is that once the local RAM buffer and SLC cache are saturated, performance tends to fall off a cliff when the true speed of the NAND is exposed.

Based on read speed. 1 MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors. It's worth noting that this drive can get hot when pushed, just like the SN850 in fact. It hit 76°C after a long day of testing, although that was without any direct cooling on it at all, not even a heatsink. It should be fine in most systems, especially if your motherboard does come with some cooling solution.IOMeter is a well-respected industry standard benchmark. However, despite our results with IOMeter scaling as expected, it is debatable as to whether or not certain access patterns actually provide a valid example of real-world performance. The access patterns we tested may not reflect your particular workloads, for example. That said, we do think IOMeter is a reliable gauge for relative throughput, latency, and bandwidth with a given storage solution. In addition, there are certain highly-strenuous workloads you can place on a drive with IOMeter, that you can't with most other storage benchmark tools.

It's in the real-world tests where the SN770 really struts its stuff though, with little between it and the Crucial P5 Plus. In very real terms, you'd be hard pushed to tell the difference between the two in day to day operations, and given this is the cheaper drive right now, that counts for a lot. If you need better performance, then the SN850 is clearly the better drive, but you will pay considerably more for it. While the 500GB model is less kneecapped, it’s the 1- and 2TB versions that bask in the performance and value sunshine, and I’d recommend those.Get into the game fast as you zoom past load times with blazing speeds of up to 5,150MB/s (1TB and 2TB models). In short, this may be the cheapest Gen 4 branded drive by some margin. However, I need to point out that some of the competitor devices support hardware encryption and have greater sustained performance for those that write large volumes of data. Overall, the SN770 represent good value and is undoubtedly a better option than purchasing an end-of-line Gen3 design.

An important point on this subject is that significant wear only occurs when random writes happen, with much less with sequential and reading generally. Therefore, if you write video files as an example, that won’t impart the same amount of wear to NAND cells as random writes of small files. The controller eschews the DRAM cache used by some pricier drives, instead enlisting your PC's main memory as a host memory buffer (HMB). This makes the SN770 the latest of several recent M.2 drives to employ DRAM-less architecture; others include the XPG Atom 50 and the WD Blue SN570. Although dropping DRAM helps reduce a drive's cost, it can potentially hurt performance, but there was scant evidence of that when we benchmarked the SN770 using our testbed system.Klarna Bank AB (publ) is Authorised by the Swedish Financial Services Authority (Finansinspektionen) and is subject to limited regulation by the Financial Conduct Authority. I did some tests in Game Mode, and it didn’t offer any dramatic improvement over the normal operations of the drives in the benchmarks I use. That’s to be expected as Game Mode, according to Western Digital, is meant to enhance performance with game workloads, and synthetic benchmarks don’t have the same workload. The SN770 isn’t the first NVMe drive I’ve seen with this configuration from Western Digital. It previously used this approach on the Over the years, I have reviewed iPad and iPhone science apps, plus the occasional camera, laptop, keyboard, and mouse. I've also written a host of articles about astronomy, space science, travel photography, and astrophotography for PCMag and its past and present sibling publications (among them, Mashable and ExtremeTech), as well as for the PCMag Digital Edition.
