Frequently Asked Questions

SATA vs SAS hard drive: what is the difference?

SATA drives use a 6Gb/s interface and suit NAS, surveillance and general storage. SAS drives run at 6Gb/s or 12Gb/s and connect to SAS controllers and backplanes. SAS controllers usually accept SATA drives, but SATA-only controllers cannot run SAS drives.

What is a SAS hard drive?

A SAS (Serial Attached SCSI) hard drive is a server HDD that connects to a SAS controller or backplane. SAS is common in enterprise servers and storage arrays. We stock SAS 12Gb/s and 6Gb/s models, including one NL-SAS drive.

What is an enterprise hard drive?

It is a drive designed for servers and storage systems. Many models in families such as Seagate Exos, WD Gold, WD Ultrastar DC and Toshiba MG Series are rated up to 2.5 million hours MTBF and up to 550TB/year workload.

What types of server hard drives are there?

They are grouped by interface (SATA, SAS or SCSI), form factor (3.5-inch or 2.5-inch), spindle speed (5,400 to 15,000 RPM) and use: enterprise, NAS, surveillance or desktop. OEM drives from Dell, HPE, Lenovo, NetApp and IBM are listed by the server maker’s part number.

New vs Refurbished: what is the difference?

New drives are unused and carry the full manufacturer warranty, and M9 Technology helps you start a claim. Refurbished drives are tested before dispatch and come with a 3–6 month warranty. Both conditions are listed in this category, so check the condition on each product page before you request a quote.

How fast can I get a quote, and do you ship worldwide?

Send a part number or a full parts list, and you’ll get a quote within 1-2 hours during business hours. We ship worldwide, and in-stock orders dispatch the same business day once payment has cleared.
