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

Product Information

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.

Equipped with advanced thermal management technology that helps maintain consistent performance, this reliable drive comes in an M.2 SSD form factor for compatibility with modern motherboards and laptops. Get up to 20% more power efficiency at maximum speed over the previous generation1 (1TB model) for an even better overall gaming experience on your portable rig. The SN770 can fit in a Sony PlayStation 5, but WD does not claim compatibility with that gaming console. Its sequential read speed is below Sony's recommended 5,500MBps, and the PS5 does not support HMB architecture. The XPG Atom 50 suffers the same limitations, but ADATA still touts it as PS5-compatible. (Any M.2 SSD used in a PS5 will be a secondary drive primarily used for game storage, so peak speed is not the primary consideration. But we still recommend looking for a drive that meets Sony's spec and asserts compatibility.)

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. In all test runs, we rebooted the system, ensured all temp and prefetch data was purged, and waited several minutes for drive activity to settle and for the system to reach an idle state before invoking a test. All of the drives here have also been updated to their latest firmware as of press time. Where applicable, we would also typically use any proprietary NVMe drivers available from a given manufacturer, but all of the drives featured here used the Microsoft driver included with Windows 11. 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.

Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. 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.

The synthetic performance as recorded by ATTO and AS SSD show the SN770 trails the Crucial P5 in terms of reads, although the writes are much closer. The 4K performance is relatively impressive though and shows that the SN770 has something to offer in this crowded marketplace. It's not too surprising that this drive outperforms Samsung's DRAM-less offering, as that is a PCIe 3.0 drive, after all, but the extent to which it does is impressive.The "terabytes written" spec is a manufacturer's estimate of how much data can be written to a drive before some cells begin to fail and get taken out of service. (TBW tends to scale 1:1 with capacity, as with the drives cited here.) WD's warranty covers the SN770 for five years or until you hit the rated TBW figure in data writes, whichever comes first.
