Silver 3.5 inch SATA hard drive with green circuit board visible

DELL

DELL ST31000524NS 1TB 7200RPM 3Gb/s 3.5" SATA internal hard drive

SKU CH-JRSC-BS8CC

A 1 TB 7200 RPM SATA drive with 32 MB cache for PS5500 and PS6500 arrays

  • 1 TB capacity for desktop storage
  • 7 200 RPM spindle speed for responsive data access
  • 32 MB cache buffer to smooth read and write operations
  • SATA 3 Gb/s interface for broad motherboard compatibility
  • Designed for Dell EqualLogic PS5500 and PS6500 arrays

Dell EqualLogic 1 TB SATA drive

This 3.5-inch internal hard drive delivers 1000 GB of storage on a SATA 3 Gb/s interface. It spins at 7200 RPM and includes a 32 MB cache buffer. The unit is supplied new and carries Dell part numbers 2HR85 and 02HR85 for the PS5500 and PS6500 storage arrays.

Replaces earlier 3 Gb/s SATA disks

The drive upgrades capacity within the same 3 Gb/s SATA generation used by the PS5500 and PS6500 series. The jump is worthwhile when an array slot needs the full 1000 GB capacity at 7200 RPM rather than a smaller or slower spindle. It does not move the interface to 6 Gb/s, so controllers limited to 3 Gb/s see no protocol change.

Verify 3.5-inch bay and 3 Gb/s SATA port

Confirm the chassis has a free 3.5-inch drive bay and that the backplane or controller presents a SATA 3 Gb/s connection. The PS5500 and PS6500 trays accept this form factor directly; other servers need a compatible carrier. No 6 Gb/s negotiation is required, but the port must support 3 Gb/s operation.

Questions about this item

Will the 3.5" SATA drive fit a standard 3.5" drive bay in a Dell EqualLogic PS5500 or PS6500 array?

Yes, the 3.5-inch form factor matches the standard drive bays in the PS5500 and PS6500 series, and the SATA connector aligns with the backplane.

What is the correct way to install the drive into the EqualLogic carrier so the SATA connector seats properly?

Slide the drive into the carrier until the SATA data and power connectors engage fully with the backplane, then secure the carrier latch; the common error is stopping before the connector clicks.

How often should the 32MB cache drive be monitored for SMART reallocated-sector counts in a PS5500 or PS6500 RAID set?

Check SMART attributes at least monthly; a rising reallocated-sector count on the 1000GB drive signals it should be replaced before the array rebuilds.
