Can you mix SATA and SAS?

Distinguished. While you can use a combination of SAS and SATA hard drives running on the same controller, you cannot mix them in the same array. This means that if the hard drives are configured together in any sort of array, you would need to replace that SAS hard drive with an identical SAS hard drive.

Are SATA and SAS drives interchangeable?

SAS controllers can handle both SAS and SATA drives. SATA controllers cannot talk to SAS drives, only SATA drives. SAS connectors have an extra set of pins and a lockout feature, so SATA cables/connectors will not fit on a SAS drive. SAS cables, however, will work with SATA drives.

How many HDD can be connected using SAS?

SAS controllers overcome this 1:1 port/drive constraint by leveraging expander technology. Instead of being limited to a maximum of eight drives on an eight-port SATA controller, an eight-port SAS controller supports the connection of up to 128 SATA and/or SAS drives per port.

Can you mix SAS and SATA in RAID?

You cannot install SATA drives on the same SAs drive array but on a different array. Make sure the RAID controller supports SATA drives.

What is the difference between SAS and SATA hard drives?

SAS-based hard drives are faster and more reliable than SATA-based hard drives, but SATA drives have a much larger storage capacity. SAS stands for Serial Attached SCSI (pronounced “scuzzy”) or Serial Attached Small Computer System Interface, while SATA stands for Serial ATA or Serial Advanced Technology Attachment.

Why is SAS cheaper than SATA?

SAS hardware is more complicated, and that makes it more expensive. On the bright side, SAS hardware is more durable than SATA. The MTBF (mean time before failure) of SATA is 1.2 to 1.6 million hours. That means that SATA tech is likely to run for well over a million hours before it needs to be replaced [7].

Can you mix SAS and SATA drives in a RAID array?

What is an SAS SSD?

A SAS SSD (Serial-Attached SCSI solid-state drive) is a NAND flash-based storage or caching device designed to fit in the same slot as a hard disk drive (HDD) and use the SAS interface to connect to the host computer. The most common drive form factors for a SAS SSD are 2.5-inch and 3.5-inch.
