8 TB SAS drive for array expansion

The HP M0S90A provides 8 TB of storage on a 3.5 inch form factor with a SAS 12Gb/s interface. It spins at 7200 RPM and uses 512e sector formatting. The drive is built for HP MSA 1040 and MSA 2040 storage arrays.

SAS 12Gb/s bus caps sustained throughput

The 12Gb/s SAS link sets the maximum interface bandwidth for this drive. Real-world sustained transfer rates are limited by the 7200 RPM mechanical speed and the 512e sector structure. The interface cannot overcome the physical latency of rotating media.

Replaces smaller SAS drives in MSA arrays

This drive upgrades capacity in existing HP MSA 1040 or MSA 2040 enclosures that accept 3.5 inch SAS modules. The jump is worth it when current volumes hit capacity limits and the array firmware supports 8 TB LUNs. It does not add a second controller or change the RAID level.

Perguntas sobre este artigo

Should I choose the 8TB capacity or is a smaller size available for this M0S90A drive?

This model is offered only in the 8TB capacity. If you need a different size, you would have to select a different part number from the HP MSA range.

What does the 7200 RPM spindle speed mean for daily workloads on this drive?

The 7200 RPM rotation delivers consistent throughput for sequential reads and writes, making it suitable for bulk storage, backup targets and nearline access in MSA arrays.

How does the SAS 12Gb/s interface limit real-world transfer rates on this 3.5" drive?

The 12Gb/s SAS link caps the interface burst at 12Gb/s, but sustained throughput will be lower and depends on the 7200 RPM mechanical speed and the controller in your MSA 1040 or 2040.
