4TB M.2 NVMe SSD for creators

The SanDisk WDS400T4B0E-00BKY0 is a 4TB internal solid-state drive built for consumer workloads. It fits the M.2 2280 slot and connects through a PCIe Gen4 x4 interface. The drive targets users who need large capacity for creative projects and everyday multitasking.

PCIe Gen4 x4 interface with HMB

The single specification that decides compatibility is the PCIe Gen4 16GT/s interface operating across four lanes. The controller uses host memory buffer technology instead of on-board DRAM. This design works with any motherboard that provides an M.2 key-M slot wired for PCIe 4.0 or 3.0 operation.

4TB capacity with 1200 TBW endurance

The 4TB volume holds extensive media libraries, project files and applications. Rated endurance of 1200 TBW supports heavy write workloads such as video editing and large dataset processing. Sequential reads reach 5500 MBps and writes reach 5000 MBps, while random performance hits 690000 read IOPS and 900000 write IOPS.

Perguntas sobre este artigo

How does the 5500 MBps sequential read figure translate to everyday use?

The 5500 MBps sequential read speed means large files such as video projects or game assets load quickly when the drive is installed in a PCIe Gen4 M.2 slot.

What does the PCIe Gen4 x4 interface cap at in practice?

The PCIe Gen4 x4 interface supports up to 5500 MBps read and 5000 MBps write, with 690000 IOPS random read and 900000 IOPS random write.

What physical slot and form factor does the 4TB model need to fit?

The drive uses the M.2 2280 form factor and requires an M.2 slot keyed for PCIe NVMe.
