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

Product Information

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. 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. 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.

My advice is unchanged on this subject, in that if TBW (Total Bytes Written) is potentially an issue for you, then buy the largest capacity drives to better distribute the workload between NAND cells. 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.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.

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.

Get into the match fast as you zoom past load times with blazing speeds of up to 5,150MB/s 1 (1TB and 2TB models). Depending on how you intend to use an SSDs, endurance is either something you are concerned about or not. For those that hammer their drive relentlessly, the SN770 is an average performer in terms of how much writing it can handle.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. Get up to 20% more power efficiency at maximum speed over the previous generation 3 (1TB model) for an even better overall gaming experience on your portable rig.

When Western Digital sent my review sample, it was specifically mentioned not to test it in a PS5, and while it might work in some way, this isn’t something I’d recommend you do. Vya Domus Does 7900XT still has high idle consumption on multiple monitors? And should I wait for the Supers even when I'm leaning towards AMD cards? ( 5) 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.) While many people are still using SATA SSDs, and a few even conventional hard drives, most desktop PCs and laptops are now using PCIe NVMe technology.

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. Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. Not having a DRAM cache reduces cost but impacts on performance, though the extent of this speed reduction is dependent on the amount of drive space left to be dynamically used as an SLC cache and power of the host systems memory subsystem.
