Intel DC S3700 100GB 2.5-inch SATA Enterprise SSD (G81068-203)
The Intel DC S3700 100GB (G81068-203) is a write-intensive enterprise SATA solid-state drive in a 2.5-inch 7mm form factor, operating over a SATA 6Gb/s (SATA III) interface. This is a data center SSD from Intel's S3700 series, built on 25nm HET (High Endurance Technology) MLC NAND — it is not a consumer SSD, not an NVMe drive, and not SAS-compatible. Condition: Refurbished — Tested & Certified by T.E.S IT-SOLUTIONS.
Engineering Context
The Intel DC S3700 was a benchmark enterprise SATA SSD known for its exceptional write endurance and consistent latency under sustained load. With an endurance rating of 10 DWPD (Drive Writes Per Day), the 100GB model delivers approximately 365 TBW (Terabytes Written) over its rated lifespan. Sequential performance reaches up to 500 MB/s read and 460 MB/s write, with random I/O up to 75,000 IOPS read and 36,000 IOPS write (4K). Typical read latency is approximately 50 µs. The proprietary Intel controller and HET-MLC NAND deliver predictable performance with minimal latency variation under sustained write pressure, making the S3700 a reference product for latency-sensitive enterprise applications.
Deployment & Use Cases
Server Boot / OS Drive: High-endurance 100GB boot drive for servers requiring reliable, write-tolerant OS storage in data center environments.
Write-Ahead Logging (WAL): Database write-ahead log and journal storage where write endurance is critical — the 10 DWPD rating supports continuous write activity from database engines (PostgreSQL, MySQL, Oracle).
Caching Tier: Small-capacity, high-write-endurance SSD for ZFS ZIL/SLOG, SAS controller write caching, or storage array caching layers.
Legacy Server Refresh: Direct replacement for aging S3700 drives in deployed Intel-based servers and storage appliances.

Compatibility & Hard Constraints
SATA Only: The Intel DC S3700 (G81068-203) uses SATA 6Gb/s. It does not support NVMe or SAS protocols. Maximum throughput is capped at ~500 MB/s by the SATA III interface ceiling.
100GB Capacity Limitation: Suitable for boot/OS, WAL, and caching use cases only. Not sufficient for application data, VM datastores, or database storage. For higher capacity, consider 200GB, 400GB, or 800GB S3700 models.
7mm z-height: Fits standard 2.5-inch 7mm drive bays. No adapter needed for most server trays.
Previous Generation: The DC S3700 is a legacy Intel series. Current Intel enterprise SATA replacements are the D3-S4520 (read-intensive) and D3-S4620 (mixed-use/write-intensive).
