4TB SSD Average Price

4TB drives are for large game libraries, high-resolution video work, and NAS/workstation builds that want speed at scale. This chart tracks the average 4TB SSD price over time, split by interface.

4TB single-sided M.2 drives are increasingly common, but check your laptop or motherboard clearance before buying. Form factor matters for fit: most consumer NVMe drives are M.2 2280 (22mm × 80mm), while compact laptops use shorter 2230/2242 sticks; SATA SSDs are 2.5-inch; and enterprise NVMe uses U.2/U.3 or EDSFF (E1.S/E3.S). PCIe generation sets the ceiling — PCIe 3.0 (~3,500 MB/s), PCIe 4.0 (~7,000 MB/s), and PCIe 5.0 (~12,000+ MB/s) — but a drive only hits its rated speed in a slot of the same generation.
