2.5" SATA SSDs

2.5-inch SATA SSDs are the universal server flash format — the SFF (small form factor) drive that drops into almost any 6Gb/s SATA backplane or server bay, from boot mirrors to bulk read-intensive tiers. Every drive here is a genuine enterprise/data-center SSD sold by exact manufacturer part number: Samsung PM-series, Micron, Intel/Solidigm and the HPE and Dell OEM-branded equivalents, across read-intensive, mixed-use and write-intensive endurance classes. We list New, Refurbished and Recertified stock side by side so you can compare a sealed drive against a tested one for the same slot and endurance. Because SATA is broadly compatible, these fit most chassis — just confirm the caddy and controller for your server. Every unit is health-tested and warranty-backed, ships fast from the US, and purchase orders are welcome — use the bulk-quote link on any drive for volume pricing or an endurance/compatibility check.

The 2.5" SATA form factor

Small form factor (SFF) SATA is the most widely compatible enterprise flash there is - it drops into any 2.5-inch bay, SATA or SAS backplane, on servers going back a decade.

7mm vs 15mm height: Most SATA SSDs are 7mm (fits every SFF bay and laptop-style trays). 15mm drives are rarer at SATA and only fit full-height bays - check the caddy.
Interface and speed: SATA III 6Gb/s tops out around 550 MB/s. Plenty for boot, OS and read-heavy tiers; choose SAS or NVMe when the workload needs more throughput or dual-port redundancy.
Caddies and OEM keying: HPE and Dell OEM drives ship keyed for their trays and are recognised by iLO / iDRAC. A bare drive works in the same bay with the matching third-party caddy.

Endurance classes (DWPD)

Drive Writes Per Day is how much of the drive's capacity you can write every day for the warranty period. It is the single most useful spec for choosing between two SSDs of the same size.

Class	DWPD	Built for	Typical products
Read-intensive (RI)	0.5-1	Boot, web, content, read-heavy databases, VDI images	Samsung PM883/PM893, Micron 5300 PRO, Intel/Solidigm S4510/S4520, Kingston DC600M
Mixed-use (MU)	3	Virtualization, OLTP, general-purpose server storage	Samsung SM883, Micron 5300 MAX, Intel S4610/S4620
Write-intensive (WI)	10	Logging, caching, heavy write workloads	Older SAS/SATA WI parts, mostly replaced by NVMe today

A 3.84TB drive at 1 DWPD is rated for 3.84TB of writes every day for 5 years - about 7 PB total (TBW).

New vs Recertified vs Refurbished

Every part is sold by exact manufacturer part number and ships warranty-backed. Here's what each condition means so you can weigh price against your workload.

New: Factory-sealed and unused, with the full manufacturer warranty. The safest choice for a fresh build or a warranty-sensitive deployment.
Recertified: OEM-recertified and restored to original specification, typically with low power-on hours. Health-tested and backed by our own replacement warranty — the same usable capacity for a lower price.
Refurbished: Professionally tested working pulls, wiped and inspected. A cost-effective option for labs, cold storage and non-critical tiers, warranty-backed.

Frequently asked questions

Which endurance class of SATA SSD do I need?+

Read-intensive (≈1 DWPD) suits boot and read-heavy tiers; mixed-use (≈3 DWPD) suits general virtualization; write-intensive (≈5+ DWPD) suits databases and caching. Each product's spec table lists its DWPD — match it to your write workload.

Will a 2.5-inch SATA SSD fit my server?+

Almost always — 2.5-inch SATA is the most broadly compatible enterprise flash format. Confirm your bay is SFF (2.5-inch) and you have the correct caddy for your chassis; OEM-branded drives ship keyed for their trays.

New, Refurbished or Recertified?+

New is factory-sealed with full warranty; Recertified/Refurbished are tested to spec with low writes and carry our warranty at a lower price. For a matched set, use the bulk-quote link.
