Seagate ST900MM0018 Enterprise Performance 10K Hard Disk Drive

Seagate ST900MM0018 is a 900 GB Savvio 10K Enterprise Performance 10K SAS hard disk drive designed for data centers, delivering 12 Gb/s SAS connectivity, a 128 MB cache, and TurboBoost caching that uses 32 GB of NAND flash to accelerate I/O and reduce latency. Housed in a 2.5-inch form factor with a 15.0 mm height, 70.1 mm width, and 100.45 mm depth, it weighs about 0.19 kg, spins at 10,000 RPM, and supports external transfer rates up to 1200 MB/s with an average latency of 2.9 ms. It operates from 5 to 55 C (operating) and -40 to 70 C (non-operating), tolerates up to 40 G shock, and carries a 5-year limited warranty with an AFR around 0.44%. The drive uses 32 GB eMLC NAND under TurboBoost, managed by Intelligent NAND Endurance Management, and the family includes self-encrypting drive variants (e.g., ST900MM0068) for security-conscious deployments.
