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 "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.

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.

Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. 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 into the match fast as you zoom past load times with blazing speeds of up to 5,150MB/s 1 (1TB and 2TB models).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. 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. Entre no jogo rapidamente vencendo os tempos de carregamento com velocidades de até 5.150 MB/s 1 (modelos de 1 TB e 2 TB). 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.
