Our Take

Best for: Gamers wanting fast load times and extra storage for their PC or PS5.

The WD_BLACK SN770 2TB is a solid Gen4 NVMe SSD built for gaming. With sequential reads up to 5150MB/s and writes up to 4850MB/s, it slashes load times and supports Microsoft's DirectStorage for future games. The 2TB capacity gives plenty of room for a large library plus upcoming updates. It's DRAM-less, which means sustained write performance isn't as high as premium drives, but for gaming workloads that's rarely a bottleneck. The WD_BLACK Dashboard software lets you monitor health and enable gaming mode. At $348, it's $58 off the typical $406 price, making it a great value for a high-capacity Gen4 drive.

Price Analysis

The sale price of $348 is 14% below the original $406.35. Recent 30-day and 90-day averages hover around $406-418, so this is a notable discount. It's a good time to buy if you need a 2TB Gen4 drive.

Common Questions

Is this SSD compatible with the PS5?

Yes, the WD_BLACK SN770 is a PCIe Gen4 drive that meets PS5 speed requirements. However, it does not include a heatsink; you may need to add a third-party heatsink for optimal thermals in a PS5.

What is the read and write speed?

Sequential read speed up to 5150MB/s, sequential write up to 4850MB/s for the 2TB model.

Does it have a DRAM cache?

The SN770 uses a DRAM-less design with HMB (Host Memory Buffer) technology. This keeps costs down and is fine for gaming, but sustained writes may be lower than DRAM-equipped drives.
