SAS SSDs
Enterprise SAS SSDs — 2.5" SFF for Dell PowerEdge and HPE ProLiant
Enterasource stocks enterprise SAS SSDs in 2.5" SFF form factor for Dell PowerEdge, HPE ProLiant, and Supermicro servers. SAS (Serial Attached SCSI) solid-state drives are the standard high-performance storage media for enterprise RAID configurations — offering faster random IOPS than SAS HDDs, dual-port redundancy for HA deployments, and full SMART monitoring through the server’s RAID controller.
SAS SSDs connect to the server’s SAS HBA or RAID controller (Dell PERC, HPE SmartArray) rather than directly to the motherboard like NVMe drives. This makes them appropriate for systems with existing SAS backplanes and RAID controllers without requiring additional PCIe adapters. We carry them in a wide range of capacities across multiple SAS generations; filter by capacity to find the size you need.
All SAS SSDs are tested with SMART data verified and controller-level diagnostics run before listing. Compatible caddies are available separately.
SAS SSD vs NVMe vs SATA SSD: Which Is Right for Your Server?
| Interface | Throughput | IOPS (4K Random Read) | Redundancy | Best For |
|---|---|---|---|---|
| SAS SSD (12G) | Up to 1,200 MB/s per port (12 Gb/s interface) | Higher than SATA, lower than NVMe | Dual-port (HA capable) | RAID arrays, existing SAS backplanes, HA clusters |
| NVMe SSD | Up to 7,400 MB/s (Gen 4) | Highest of the three (PCIe Gen 4 and Gen 5) | Single- or dual-port, by model | Latency-critical apps, scratch/cache, all-flash |
| SATA SSD (6G) | Up to 600 MB/s (SATA 6Gb/s interface) | Lowest of the three | Single-port | Boot drives, secondary storage, cost-sensitive deployments |
SAS SSDs are the right choice when your server has a SAS backplane and RAID controller already in place, you need dual-port redundancy for high-availability deployments, or you’re expanding existing SAS SSD capacity in a running system. NVMe is faster but requires PCIe connectivity — not all server chassis and RAID configurations support NVMe expansion without additional hardware.
- Are SAS SSDs compatible with all Dell PowerEdge and HPE ProLiant servers?
- SAS SSDs need a SAS-capable drive bay and backplane plus a SAS HBA or SAS RAID controller, and they do not work with SATA-only controllers or bays. Most Dell PowerEdge (12th gen and newer) and HPE ProLiant (Gen 8 and newer) servers with SAS backplanes support SAS SSDs. Verify your specific chassis configuration and RAID controller model before ordering.
- What capacities do SAS SSDs come in?
- We carry SAS SSDs in a wide range of capacities, mostly in 2.5-inch SFF form factor; filter by capacity to see every size we list. Inventory varies. Contact us if a specific capacity is not listed.
