Digital storage manufacturer Western Digital has started shipping its Black SN770 series. The SN770 series comes as a successor to the last generation SN750 series of NVMe SSDs. The new series features the PCIe4 x4 interface for maximum read and write rates of 5150MB/s and 4850MB/s, respectively, compared to “only” ~3500 MB/s o the fastest PCIe3 x4 drives.
Faster PCIe4 x4 drives like Acer Predator GM7000 or ADATA Gammix S70 are available with transfer rates nearly 7000+ MB/s each to be noticeably faster than what the SN770 series delivers. However, such drives are also more costly at $150 and $145 for the 1TB ADATA and 1TB Acer, respectively, compared to just $139 for the 1TB Western Digital SN770.
It’s worthy noting that although the Western Digital SN770 drives are PCIe4 compatible, they are not officially designed for the PlatStation 5. The manufacturer does not guarantee compatibility with the Sony console which recommends faster transfer rates that what the SN770 series can provide.
