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

Product Information

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. Use of this software requires download and installation to a system connected to at least one of the compatible Western Digital (WD, SanDisk, G-Technology) storage products. SSD and their stripped-down design for reasons of cooling and efficiency) but the drive arrives well protected and held between two layered windows of hard plastic. The number of channels refers to the number of storage chips that this controller can access at once.

We consider it superior to testing against games themselves because, as a trace, it is much more consistent than variations that will occur between runs on the actual game itself. The interface is compatible with leading CPU and motherboard platforms and backwards compatible with PCIe Gen3. The power-efficient drive (according to WD, it consumes 20% less power than its predecessor, the WD Black SN750) lacks a heat sink or spreader, relying on WD's thermal management technology and any thermal hardware on your PC's motherboard.The WD Black SN770 SSD arrives with 5 years of manufacturers warranty (as well as a terabytes written threshold to that warranty as found with most modern SSDs) which is pretty standard.

Zoom past load times and get into the action now with a purpose-built gaming drive that boasts up to 40% faster performance and up to 20% more power efficiency at maximum speed over the previous generation 3 (1TB model), plus a PCIe® Gen4 interface 4 that delivers blazing speeds of up to 5,150MB/s 1 (1TB and 2TB models). There is also support for standard SSD management components such as Trim, SMART and secure erase capability via the Format NVM command. Ordinarily, I would introduce tests like BlackMagic and AJA into the mix here, but even a short burst of testing on an NVMe like this would over saturate the cache memory on board. But what that means is the 2TB model, just as it's spec'd by WD, will not be as fast as the 1TB model due to its 1024Gbit die composition.Sustained performance was unsurprisingly poorer as the borrowed system memory and controller became overworking in the larger and longer-running tests, but in shorter bursts, the drive clearly did what they said it can do and more. Now as well and good as this all sounds, Host Memory Buffer (HMB) architecture SSDs such as the DRAMless WD Black SN770 is by no means a perfect ideal basis of storage for prosumer and power-users. I am interested in your upcoming comparison with the Seagate Firecuda 520 because that’s the new SSD I just bought.

The SN770 is not the only DRAMless SSD in the market, but IS one of the highest performing examples right now and one of few in the PCIe4 tier. Using my Beelink Mini S Windows 11 PC, with the drive in two different USB enclosures, it will NOT work! BiCS 5 is true 4-plane flash and, as we've pointed out previously and provided it's managed by a controller running firmware that plays nice with it, is by far the best-performing flash currently adorning consumer SSDs. Now, we just assumed the 2TB model would be arrayed with two 1TB flash packages, and if so, despite WD's quoted performance specs, it might be even faster than the 1TB model.Since 2004, I have worked on PCMag’s hardware team, covering at various times printers, scanners, projectors, storage, and monitors. Recording a 1080p gameplay video at 60 FPS with OBS (Open Broadcaster Software) while playing Overwatch. Most drives designed for gen 3 do not exceed 2000MB/s and are highly inconsistent when doing mass transfers, some of which drop down to 50MB/s. PCIe Generation 4 allows a potential bandwidth of 8,000MB/s (8GB/s) and although the SN850 before it saturated the bulk of that at 7,000MB/s+, the WD Black SN770 hits a maximum 5,150MB/s. As WD generally utilizes only in-house components and manufacturing teams on their drive media, the WD Black SN770 SSD is architecturally similar in parts to several other SSDs in their past/present portfolio, including the WD Blue NVMe and WD Black SN850 before it.
