Enterprise SSDs — SAS, SATA, NVMe
Samsung, Micron, Kingston, Intel, WD — validated for HP/Dell/Cisco/Lenovo server backplanes.
About Enterprise SSDs
Enterprise SSDs differ from consumer SSDs in three critical ways: power-loss protection (PLP capacitors preserve in-flight writes during power failure), sustained write endurance (measured in DWPD — drive-writes-per-day), and predictable performance under steady-state load (consumer drives throttle after ~30 seconds of sustained writes; enterprise drives maintain rated speed indefinitely).
Pro Disk Network stocks the top-tier enterprise SSDs: Samsung PM893 (SATA), Samsung PM9A3 (NVMe), Micron 7450 series, Kingston DC500 / DC2000B, Intel D3-S4520, and WD Ultrastar DC SN650. Form factors: 2.5" U.2, M.2 22110, E1.S (EDSFF), E3.S. Capacities: 480 GB to 30.72 TB.
Picking enterprise SSDs: DWPD endurance tiers
- Read-intensive (1 DWPD) — read-heavy workloads (web servers, read replicas, content delivery). Lowest cost per TB. PM893, Intel D3-S4520, Micron 5400 PRO.
- Mixed-use (3 DWPD) — OLTP databases, VDI, analytics. Middle ground. PM9A3, Micron 7450 MAX, Kingston DC500M.
- Write-intensive (10+ DWPD) — caching tiers, journal drives, write-heavy HPC. Samsung PM1735, Intel Optane (legacy), Kioxia CM6.
For most general-purpose server deployments (web, app, file, moderate DB), a 1-3 DWPD read-intensive or mixed-use SSD is the right call. Buying 10 DWPD when you need 1 DWPD is overspending 3-5× per GB.

Frequently Asked Questions
What is DWPD on an enterprise SSD?
DWPD (Drive Writes Per Day) is the number of times you can completely overwrite the drive every day for the duration of its warranty (typically 5 years). A 3.84 TB drive with 3 DWPD endurance can handle ~11.5 TB/day of writes for 5 years — that is 21 PB of lifetime writes. Most general-purpose server workloads use less than 0.5 DWPD in practice, so a 1 DWPD drive is usually enough.
Should I buy SATA, SAS, or NVMe enterprise SSDs?
NVMe for any performance-sensitive workload (databases, virtualization, analytics) — 10× latency improvement over SATA and 3-5× throughput. SAS for legacy server backplanes that don't have NVMe slots (most HP Gen9, Dell R730 era), or when you need dual-port high-availability paths. SATA for cost-sensitive bulk storage where SSD speed matters but SATA is the available interface. Modern Gen10/Gen11 servers (HP DL380 Gen11, Dell R750, Lenovo SR650 V3) all ship with NVMe backplanes — prefer NVMe there.
Are Samsung PM883 and PM893 compatible with HP ProLiant?
Yes — Samsung PM883 (Gen1 SATA) and PM893 (Gen2 SATA) are fully compatible with HP ProLiant DL360/DL380 Gen9, Gen10, and Gen11 servers using the standard SATA/SAS backplane. They also work in Dell PowerEdge R730/R740/R750 and Cisco UCS C220/C240. Note: for HP "SmartDrive" chassis, you may need HP-branded caddies — we stock these separately.
Do enterprise SSDs need TRIM?
Enterprise SSDs handle garbage collection and wear leveling in firmware without relying on TRIM commands. Most enterprise RAID controllers do not pass TRIM to drives in RAID arrays (Dell PERC H730/H740 historically did not, for example). This is fine — enterprise drives are designed around this and maintain sustained performance via internal over-provisioning (typically 7-28% of raw NAND reserved). Consumer SSDs rely on TRIM and should not be used in RAID arrays.
What is the difference between U.2 and M.2 enterprise SSDs?
Both are NVMe. U.2 is a 2.5" form factor with a SAS/SATA-compatible connector (SFF-8639), hot-swap capable, higher power budget (25W), longer MTBF, used in enterprise server backplanes. M.2 is a gum-stick form factor that plugs directly into the motherboard, no hot-swap, lower power budget (~11W), typically used for boot drives and low-density deployments. For any storage tier you need to hot-swap, use U.2.
