SAS Drives
Enterprise SAS drives — 10K and 15K RPM 2.5″ and 3.5″ hard drives plus 12Gb/s SAS SSDs pulled from Dell, HPE, and Lenovo servers, securely wiped and SMART-tested before sale.
SAS Drives — Enterprise 10K & 15K HDDs and 12Gb/s SSDs
SAS is the drive interface servers are built around: dual-ported, full-duplex, and engineered for 24/7 duty in RAID arrays and storage shelves. A SAS hard drive spins at 7.2K, 10K or 15K RPM behind a 6Gb/s or 12Gb/s link, and SAS SSDs push the same interface to flash speeds. Every SAS drive we list is securely wiped to industry standards, SMART-tested, and listed with its hours of operation. Browse the drives below, or see all hard drives, solid state drives and the full storage department.
7.2K, 10K, 15K or SSD?
- 7.2K nearline SAS — the capacity tier: high-capacity 3.5″ and 2.5″ SAS hard disks for backup targets and bulk storage arrays.
- 10K & 15K SAS — the classic performance spinners: 2.5″ and 3.5″ SAS hard drives for latency-sensitive RAID arrays that have not moved to flash.
- SAS SSD — 12Gb/s flash with dual-port redundancy — the drop-in speed upgrade for any SAS backplane.
Remember the plumbing: SAS drives need a SAS controller or backplane — a SAS HBA runs SATA drives happily, but a SAS drive will not work on a plain SATA port. Hot-swap bays also want the model-correct tray or caddy. Tell us your server model and we will confirm drive, tray, and controller before you order. Running SATA-only hardware? See our SATA drives.
Sizing a RAID Array?
Our free RAID calculator shows usable capacity, rebuild time, and failure risk for RAID 0–60, and the IOPS calculator estimates real-world performance for 10K and 15K spindles including the RAID write penalty.

Quick Answers: Buying SAS Drives from PCSP
What is the difference between SAS and SATA drives?
SAS (Serial Attached SCSI) is the enterprise interface: dual ports for redundant paths, full-duplex transfers, deeper command queuing, and 12Gb/s links against SATA’s 6Gb/s. SATA wins on price per terabyte; SAS wins on sustained performance and reliability under RAID workloads. A SAS controller runs both — a SATA port runs only SATA.
Will a SAS drive work in my desktop PC?
Not on the motherboard’s SATA ports — the connectors look similar, but a SAS hard disk requires a SAS HBA or RAID controller. In servers and workstations with a SAS backplane they are plug-and-play; in a desktop, add an inexpensive HBA card first.
Are used 10K and 15K SAS hard drives reliable?
These are enterprise-class mechanisms rated for continuous duty. We SMART-test every drive, report hours of operation in the listing, and drives that fail our checks never ship. Loose drives are covered by 90-day returns — defective units come back at our expense.
Do I need a tray or caddy for a SAS drive?
In a hot-swap bay, yes — each server family takes its own caddy, and a 2.5″ drive in a 3.5″ bay needs an adapter bracket. Tell us your server model and we will bundle the correct tray with the drive, tested together.
