SanDisk 4TB NVMe SSD for AI workflows
This SanDisk 4TB internal SSD uses PCIe 4.0 x4 and NVMe to deliver sequential reads up to 6900 MBps and writes up to 6700 MBps, with 4KB random reads of 900000 IOPS and writes of 1100000 IOPS. It targets creators and professionals who need large capacity and fast asset loading for AI-enabled projects.
M.2 2280 DRAM-less design with HMB and encryption
The drive fits a standard M.2 2280 slot and operates without a dedicated DRAM cache by using Host Memory Buffer technology. It supports TCG Pyrite 2.01 encryption and ATA security passthrough over NVMe, and is rated for 1200 TBW with an MTTF of 1.75 million hours across an operating range of 0°C to 85°C.
Upgrade from older NVMe when capacity
Moving from an earlier PCIe generation NVMe drive to this 4TB model adds both the higher Gen 4.0 bandwidth and the QLC 3D CBA NAND capacity in a single M.2 2280 module. The jump is worth it when project files exceed current drive space and workflows benefit from sustained sequential speeds up to 6900 MBps.

Ερωτήσεις για αυτό το προϊόν
What practical throughput ceiling does the PCIe 4.0 x4 interface impose on this drive?
The PCIe 4.0 x4 link caps real-world sequential transfers at roughly 7 000 MB/s, so the drive's 6 900 MB/s read and 6 700 MB/s write ratings sit right at that ceiling.
What physical slot and clearance does the M.2 2280 form factor require?
It needs an M-keyed M.2 slot that accepts 2280-length modules; the board must provide at least 80 mm of clear space from the mounting screw to the slot's end.
How is the drive installed, and which step is most often missed?
Insert the module at an angle, press it flat, and secure it with the single M2 screw; the step most people skip is enabling the NVMe controller in the BIOS so the OS can see the drive.
