In comparison, the SN770 is a dramatically better proposition, even for those still using Gen 3 slots than the SN750. It offers much better power efficiency, making it useful for laptop users.

Details about the extent of our regulation by the Financial Conduct Authority are available from us on request.

It is quite impressive that the 2TB SN770 is the fastest of the Gen4 5,000 MB/s class SSDs, even outpacing several 8-channel drives with onboard DRAM and its smaller sibling to boot. 3DMark SSD Gaming Test 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. 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. The first important thing to understand about the SN770 is that it replaces the ageing SN750, a Gen 3 drive that peaked at reading speeds of 3,400MB/s and writes of 3,100MB/s. 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.

Firing up Crystal Diskmark, it gives us a great snapshot of how the device performs at the top end. Observe: 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. PCMark 10 Storage Test is the most advanced and most accurate real-world consumer storage test ever made. There are four different tests you can choose from; we run two of them.
