Dell 146 GB 15K SAS Drive

This new Dell 3.5-inch SAS hard drive delivers 146 GB of storage at 15,000 RPM with a 3 Gb/s interface and 16 MB cache. It is built for servers and workstations that require high-speed mechanical storage in a standard 3.5-inch bay.

Suits SAS-equipped servers needing fast 146 GB

It suits administrators replacing failed drives in Dell arrays or other systems that accept 3.5-inch SAS disks at 3 Gb/s. It is not for buyers who need more capacity than 146 GB, nor for platforms that lack a SAS backplane or controller.

3 Gb/s SAS interface determines compatibility

The drive connects only through a 3 Gb/s SAS port, so the host must provide that exact interface. A 16 MB buffer and 15,000 RPM spindle speed support demanding random-access workloads within that interface limit.

Questions about this item

Does the 146 GB drive need a 3.5" SAS 3 Gb/s backplane or controller to operate?

Yes, the drive uses a 3.5" SAS 3 Gb/s interface and requires a matching backplane or HBA for power and data.

Will the ST3146854SS run on the same SAS bus as older 3 Gb/s SAS drives without speed negotiation issues?

It operates at 3 Gb/s, so it will coexist with other 3 Gb/s SAS devices on the same domain.

How can I confirm the 15 000 RPM mechanism is spinning correctly after installation?

The drive should be recognised by the BIOS or RAID utility at its full 146 GB capacity with no SMART errors reported.
