4 TB SATA enterprise drive
The HGST MegaScale DC 4000.B HMS5C4040BLE641 is a 3.5 inch internal hard drive with a 4 TB capacity and a SATA 6.0 Gb/s interface. It is built for 24x7 operation in enterprise-class, capacity-optimised applications. The bare drive includes 64 MB cache and Advanced Format 512e technology.
Suited for bulk storage arrays
This drive fits low-workload cloud storage, massive scale-out deployments, data warehousing and disk-to-disk backup. Buyers needing higher sustained throughput for transactional databases should look elsewhere. Systems limited to legacy SATA revisions will not reach the rated interface speed.
800 K hours MTBF rating
The 800 K hours MTBF figure is the key reliability metric for multi-drive environments. Dual Stage Actuator and Enhanced Rotational Vibration Safeguard support consistent performance in dense chassis. Verify that your enclosure accepts the 26.1 mm height before purchase.

Questions about this item
Will the 3.5" form factor and SATA 6.0Gb/s interface let this drive drop into my older desktop chassis and motherboard?
Yes, the 3.5" form factor and SATA 6.0Gb/s interface match standard desktop bays and controllers, so the drive installs directly into existing hardware.
How can I verify the Advanced Format 512e and 64MB cache are active after installation?
Check the drive properties in your operating system or BIOS; they will report 512-byte emulation and a 64MB cache when the drive is recognised.
Since the packaging is listed as Bare Drive, what must I supply myself?
You will need to provide your own SATA data cable, SATA power cable, and 3.5" mounting screws or tray, as the bare drive includes none of these.
