6Gb/s SATA Server Hard Drives, 2.5 and 3.5-inch

6Gb/s SATA Server Hard Drives

Key takeaways

2,612 listings match this collection right now.
A SATA drive has a single data path, so in a dual-controller storage enclosure it cannot provide the path redundancy a SAS drive gives, even in the same backplane.
10K and 15K performance classes were built almost entirely on SAS, not SATA, so a high-RPM SATA drive is unlikely to exist; SATA drives are 7,200 RPM capacity parts.
SATA 6Gb/s spans the same capacity range as nearline SAS, from small legacy sizes up through modern helium drives, so interface and capacity are independent choices to make.

SATA 6Gb/s is the capacity-tier interface for server hard drives. A SATA drive works on a SAS backplane, which makes it the safe choice for bulk storage bays, though it lacks the dual-port redundancy of SAS.

How to choose server hard drives

Match the interface and link rate the controller or backplane presents, the bay width (2.5-inch or 3.5-inch), and the rotational class already in the array: 10K and 15K drives for latency-sensitive duty, 7200 RPM nearline drives for capacity. Replacing an array member also means matching capacity and sector format, or the controller can reject the drive.
