The move comes just before Prime Day, and follows a period when the drive had climbed as high as $400 and was selling for around $300 a month ago.\n\n## technical specs\nThe SN7100 is the successor to the SN770 and is built around SanDisk’s proprietary Polaris 3 controller paired with 218‑layer TLC (BiCS8) flash. It does not include DRAM, which can affect sustained performance during heavy, prolonged transfers, but it supports Host Memory Buffer (HMB) to mitigate this by using a portion of system memory as cache.\n\n## performance test results\nIn our tests, the drive achieved sequential read speeds of up to 7,250 MB/s and write speeds of up to 6,900 MB/s. It also boasts an endurance rating of 1,400 TBW and delivers strong random read performance while consuming less power than most PCIe 4.0 SSDs on the market.\n\n## power efficiency and thermal\nThe SN7100’s lower power draw translates into reduced operating temperatures, allowing the drive to run comfortably without an additional heatsink in most everyday workloads. This efficiency makes it particularly well‑suited for battery‑powered devices such as laptops and handheld gaming consoles.\n\n## compatibility with PS5\nThe drive is compatible with the Sony PS5, delivering performance comparable to other high‑end PCIe 4.0 SSDs while maintaining lower power consumption and temperatures.\n\n## buying advice and future outlook\nIf you’re looking for a speedy storage upgrade, the 2TB WD Black SN7100 at $242.96 is a solid deal and may be the lowest price ever seen for this model. With the drive’s price now well below its peak, it’s an opportune moment to purchase, especially as Prime Day approaches.
