The WD Black SN770M is a line of compact NVMe SSDs in M.2 2230 form factor, designed for portable gaming systems, ultrabooks, and other devices where compact size, high speed, and moderate power consumption are critical. The series is available in 500 GB, 1 TB, and 2 TB capacities, features PCIe Gen4 x4 interface, TLC 3D NAND, and supports Microsoft DirectStorage and Western Digital's nCache 4.0 technology. The 1 TB and 2 TB models deliver read speeds up to 5150 MB/s, while the 500 GB version reaches 5000 MB/s. Write speeds reach up to 4000 MB/s for 500 GB, 4900 MB/s for 1 TB, and 4850 MB/s for 2 TB. Random read performance varies by capacity: up to 460K IOPS for 500 GB, up to 740K IOPS for 1 TB, and up to 650K IOPS for 2 TB, while random write performance reaches 800K IOPS across all three models. The drive measures 30 × 22 × 2.38 mm and weighs approximately 2.8 g, making it compatible with Steam Deck, ASUS ROG Ally, and other M.2 2230-compatible devices. Write endurance depends on capacity: 300 TBW, 600 TBW, and 1200 TBW respectively. The WD Black SN770M is the ideal solution for upgrading a portable gaming device or thin notebook when you need more storage for modern games without switching to full-size M.2 2280 drives.
