DELL ST9146853SS 146GB 15K SAS 2.5 internal hard drive

SKU CH-3858-G25BC MPN ST9146853SS

A 146 GB 15K SAS 2.5-inch enterprise drive for Dell PowerEdge servers with hot-swap support

  • 146 GB capacity stores more enterprise data
  • 15K RPM spindle delivers fast transaction speeds
  • SAS 6 Gbps interface moves data quickly
  • 5 inch SFF form factor fits dense servers
  • Hot-swap tray allows drive changes without downtime

Enterprise 146 GB SAS drive

This 2.5 inch small-form-factor drive spins at 15 K rpm and connects through a 6 Gbps SAS interface. It is built for Dell PowerEdge servers and carries the Dell Enterprise product line designation. The hot-swap design allows drive replacement without powering down the host system. Tray stickers may not be included and packing may vary between retail and OEM.

Sustained workload behaviour

The 15 K spindle speed supports consistent throughput for transaction-heavy applications such as databases and virtualisation hosts. SAS dual-port architecture maintains path redundancy during continuous operation. Mechanical latency remains stable under multi-threaded I/O, avoiding the performance drops seen in lower-speed drives during extended write sequences.

Pre-purchase checks

Verify that your server backplane accepts 2.5 inch SAS drives and that a compatible hot-swap tray is available for the specific PowerEdge model. Confirm the controller or HBA supports 6 Gbps SAS links. This drive is not suited for desktop PCs or consumer laptops lacking SAS connectivity and enterprise-grade cooling.

Questions about this item

How much heat does the 15K SAS drive generate under continuous operation?

The 15K spindle speed produces more heat than slower drives, so adequate server airflow is required for reliable all-day use.

Which SAS backplane or controller must I already have for this 2.5 SFF drive to function?

A 6 Gbps SAS backplane or HBA with a 2.5-inch hot-swap bay and the correct Dell tray is needed for the drive to connect.

Will this 146GB SAS drive work in my older PowerEdge that only supports 3 Gbps SAS?

The 6 Gbps SAS interface negotiates down to 3 Gbps, so the drive will operate in legacy PowerEdge servers at the slower link speed.
