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

Product Information

But while the Atom 50 remains our top pick among budget internal SSDs, the SN770 is a highly capable alternative that runs right on its heels.

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.Now, a big part of that is that the SSD does not feature onboard memory (relying on using a portion of host system memory when in operation, a process known as Host Memory Buffer or HMB) so it needs to make sure the controller does not get overworked and spacing out the components becomes more important to maintain cooled efficiency. The DRAM on an SSD allows the Controller to have a workspace to construct and form the instructions that it needs to handle instructions in all directions. SSDs are much the same with the CPU being replaced by an SSD controller, the storage being replaced by the NAND, the motherboard being replaced by the PCB and the memory being replaced by SD-RAM/DRAM.

The WD Black SN770 SSD can utilize upto 64MB of system memory and although this will certainly get sporadic access and light-medium usage sorted, that is going to be problematic in higher usage frequency.For Western Digital to do this with 1024Gbit flash on a single package, mind you, is even more incredible than doing it with 512Gbit flash. We’ve partnered with Ontrack to provide protection for routine and extreme data loss scenarios such as drive failure, viruses, and software issues.

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.
