The WD Black SN7100 is a newer, faster upgrade to the SN770, utilizing the latest in-house Polaris 3 controller and 218-layer TLC 3D NAND flash. It delivers impressive sequential speeds up to 7,000MB/s for reads and 6,900MB/s for writes, with random performance hitting 900K IOPS read and 1,300K IOPS write. Its endurance rating is exceptional at 2,400TBW—far higher than many comparable drives. Most gamers won't approach this limit before considering an upgrade. The SN7100 is also highly energy-efficient, operating cooler and using less power than many other 4TB SSDs. Its single-sided design makes it slimmer and broadly compatible with mini PCs and ultra-thin laptops.

The primary distinction between this drive and the significantly pricier SN8100 is that the SN7100 is a DRAM-less design. It employs Host Memory Buffer (HMB) technology, leveraging a small portion of your system's RAM, rather than dedicated onboard DRAM. In real-world gaming scenarios, whether in a PlayStation 5 or a gaming PC, users are unlikely to notice a performance difference, and you enjoy considerable savings.

The WD Black SN7100 is an outstanding SSD choice for the PS5. It meets all of Sony's official requirements, including the M.2 2280 form factor, a minimum speed of 5,500MB/s, and a PCIe Gen4x4 interface. A heatsink is not pre-installed, but affordable aftermarket options (around $7) are easy to install. The drive is backed by a robust five-year warranty.
