WD_BLACK SN7100 (1 TB)

A beginner-tier 1TB Gen4 NVMe with up to 7,250 MB/s reads, the SN7100 is positioned as a power-efficiency leader that fits laptops, handhelds, and desktops alike. That low power draw is its calling card for battery-powered devices. It's DRAM-less, though, so for heavy sustained writes a DRAM-equipped drive in the SN850X class is the better choice; the SN7100 shines at efficient everyday performance.
