Best 4TB PCIe 5.0 DRAM SSDs
4TBPCIe 5.0DRAM
There are 12 4TB PCIe 5.0 DRAM SSDs in our database (12 with a direct Amazon product link). The fastest is the Corsair MP700 Pro XT at 14900 MB/s read. Sequential reads across the group span 11700–14900 MB/s.
Why this configuration
A 4TB PCIe 5.0 DRAM SSD is a flagship configuration — about the fastest consumer storage you can buy today. Gen5 roughly doubles Gen4 sequential bandwidth, which shows up in large file copies, near-instant level loading and heavy content work; the trade-offs are more heat and a higher price.
4TB starts to replace juggling several smaller drives.
Usually chosen for: enthusiasts, streamers and creators building a no-compromise rig — plus PS5 owners who want headroom.
Good fit: workstation and creative loads that hammer random I/O; enthusiasts and creators chasing peak sequential speed.
Look elsewhere for: small-form-factor or laptop builds with poor M.2 cooling.

The parts, explained
4TB handles big Steam libraries, video projects and archives.
PCIe 5.0 x4 pushes past 12,000 MB/s, though the quickest drives run hot and usually want a heatsink.
An onboard DRAM cache keeps the flash mapping table on the drive, holding random performance steady under sustained load.
Common questions
Do I need a heatsink for a PCIe 5.0 drive?
Usually yes — Gen5 controllers run hot and can throttle without cooling. Many motherboards now ship with an M.2 heatsink that does the job.
How do the links to Amazon work here?
12 of the 12 drives listed have a direct product link; for the rest we link an Amazon search on the manufacturer part number, which lands on the right listing. We deliberately don't display stock or prices on this page — check both on Amazon, they change constantly.
