4TB SATA drive for NAS arrays

This Western Digital WD4000F9YZ is a 3.5-inch internal hard drive built for 24x7x365 operation in NAS and scale-out environments. It delivers 4TB of capacity at 7200 RPM with a 64MB cache over a SATA 6.0Gb/s interface. The Se series targets cost-effective enterprise-class storage where continuous uptime matters.

Verify SATA power and bay clearance

Confirm your enclosure or server has a free 3.5-inch bay that accommodates the 26.10mm height, 101.60mm width and 147.00mm length. The host must provide a SATA 6.0Gb/s data port and a standard SATA power connector. No mounting hardware or cables are included with the bare drive.

Bare drive means no extras in the box

The unit ships without screws, brackets, cables or software utilities. You supply all mounting hardware and any RAID or management tools your NAS platform requires. This keeps the purchase focused on the drive itself for integrators who already have the necessary accessories.

Spurningar um þessa vöru

Does the WD4000F9YZ ship with cables or mounting screws?

Packaging is listed as bare drive, so no SATA data cable, power cable or mounting screws are included.

Is the 4 TB 7200 RPM Se model the right choice for a NAS array?

The Se series is built for 24x7x365 operation in NAS and scale-out architectures, offering 4 TB at 7200 RPM with 64 MB cache.

What sustained throughput can I expect from the 6.0 Gb/s SATA link in a real system?

The 6.0 Gb/s interface caps burst speed; sustained transfer will be limited by the 7200 RPM platters and 64 MB cache, typically well below the link maximum.
