3.5 inch SAS hard drive mounted in Dell hot-swap caddy

DELL

DELL 12GYY 4TB 7.2K 3.5" SAS LFF 6Gb/s internal hard drive

SKU CH-K88B-K8ZE9

A 4 TB, 7.2K RPM SAS hard drive in a 3.5-inch hot-plug caddy built for Dell PowerEdge servers

  • 4 TB capacity for large data sets
  • 2K rpm spindle for steady throughput
  • SAS 6 Gb/s interface for reliable connectivity
  • 5" LFF form factor fits standard server bays
  • Genuine Dell hot-swap caddy included for quick installation

4 TB enterprise hard drive for Dell servers

This 4 TB SAS drive spins at 7.2 K rpm and comes pre-installed in a genuine Dell hot-plug caddy. It is built for 24/7 duty cycles in compatible PowerEdge rack and tower servers. The drive uses enterprise-grade WD, Seagate or HGST mechanisms selected to Dell specifications. Buyers who need a non-Dell chassis or a different interface cannot use this unit.

Sustained 24/7 operation in multi-drive arrays

Enterprise-class firmware and rotational vibration tolerance keep performance steady during continuous read/write workloads. The 6 Gb/s SAS link supports dual-port redundancy for path failover in RAID sets. Drives are tested to a reported RMA rate below 0.5 % across more than 10 000 units sold. Workloads requiring higher throughput than 6 Gb/s or lower latency than 7.2 K rpm can deliver will hit a ceiling.

6 Gb/s SAS interface and LFF 3.5" form factor

The SAS 6 Gb/s standard caps theoretical bandwidth at 600 MB/s per port, limiting peak sequential transfer. Large form factor 3.5" dimensions restrict installation to bays that accept full-height trays. Compatibility is limited to the listed Dell PowerEdge models; servers or storage arrays outside that list will not recognise the drive. Users needing 12 Gb/s SAS speeds or 2.5" SFF bays must select a different drive.

Questions about this item

How much noise and heat does the 7.2K RPM SAS drive produce when running 24/7 in a server?

The 7.2K RPM enterprise drive is built for 24/7 duty cycles; typical 3.5" SAS models at this speed run quietly enough for rack cabinets and stay within standard operating temperature limits when airflow is adequate.

What must my system provide for the SAS 6Gb/s interface and 3.5" LFF caddy to work?

A Dell PowerEdge backplane or controller with a 6Gb/s SAS port and a 3.5" LFF hot-plug bay that accepts the included genuine Dell caddy.

Will the 12GYY caddy fit the same drive bays as the older drives in my PowerEdge R710 or T610?

Yes, the supplied genuine Dell 3.5" LFF caddy matches the hot-plug bay dimensions used across the listed PowerEdge models.
