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

Product Information

One feature the drive does not offer is 256-bit AES hardware-based encryption, which we've seen on comparable drives including the XPG Atom 50. Western Digital (or simply WD) is the world's largest manufacturer of storage solutions, mostly known for their wide range of hard disk offerings. We should note, however, that theWD Black SN770 actually managed to put up numbers higher than its rated specs but a few MB/s, so WD may be a bit conservative in those ratings. The WD Black SN850,the Crucial P5 Plus, and the Samsung SSD 980 Promatch its rated 600TBW for the 1TB model and 1,200TBW for 2TB, while the Kingston KC3000has slightly higher ratings of 800TBW for 1TB and 1,600TBW for 2TB.

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. A configuration like this is usually associated with entry-level, lower-performing drives, but as you’ll see a little later, the SN770 performs well where it matters most. slot and maxing out the bandwidth there—you're going to be limited to a peak throughput of around 3,500MB/s if you do though. The NVMe fashion these days is to not use DRAM to smooth transfers but instead use either SLC caching and, in the case of the SN770, RAM in the host PC as a buffer. Like the WD Black SN850 though, the SN770 is a PCIe Gen 4 x 4 drive, designed to offer increased bandwidth and lower latency than older PCIe Gen 3 drives, but it’s also a cost-reduced solutions that eschews a DRAM cache and leverages a scaled back controller.WD padded out the models with a 250GB option of dubious value that, according to the official numbers, isn’t worth considering. Không những thế, bạn cũng có thể thoải mái nâng cấp hệ thống trong tương lai mà không sự hết dung lượng.

While I didn’t encounter thermal throttling in my tests, avoiding any excessive build-up of heat is likely to extend the life of the drive and enable it to operate at the best possible speeds. With their acquisition of SanDisk in 2016, WD became one of the largest manufacturers for flash storage, too. The SN770 looks to improve the lot for the DRAM-less though, and with numbers like these, it deserves to. Overall, the SN770 represent good value and is undoubtedly a better option than purchasing an end-of-line Gen3 design. Under each test condition, theSSDs showcased here were installed as secondary volumes in our testbed, with a separate drive used for the OS and benchmark installations.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. And, to underline its confidence, Western Digital offers a five-year warranty if the drive doesn’t exceed quoted TBW over the entire range. The drives that offered the highest IOs, take the top spots, with theWD Black SN770 landing just above the XPG Atom 50. That would be more of a problem if Western Digital were selling the SN770 for this purpose, but it is also below the 5,500MB/s low watermark for third-party modules on the PS5 anyway. It isn't the fastest drive around, nor is it quite the cheapest (although it is close), but it does balance the two better than most.
