Seagate 1200 Architecture
The Seagate 1200 has steady performance specifications for sequential activity with all capacity points, but the 200GB features slightly lower random write performance. The drives are available in 1.8" and 2.5" form factors with a 7mm z-height.
The full-duplex 12Gb/s SAS connection features multi-path ability for failover redundancy to ensure no single point of failure. Advanced SAS error-control enables robust drive-level error correction, and full data path protection. A multi-layered error-recovery technology suite consists of ECC, LDPC (low-Density Parity Check), and Micro-RAID to protect user data. Micro-RAID is likely similar to Marvell's F.R.A.M.E. capability, which provides embedded parity to combat data loss. This combination of technologies provides a read error rate of one LBA in 10E16 bits transferred.
The SSD features an AFR of .44%, and an impressive MTBF of 2 million hours. Capacitors provide a layer of protection from host power loss. User-selectable logical block size (512, 520, 524, 528, 4096, 4160, 4192, or 4224 bytes per logical block) is also supported.
The standard Seagate 1200 features up to 10 drive writes per day (DWPD) of endurance, and the High-Endurance models offer a staggering 25 DWPD. Seagate also provides the option of Lifetime Endurance Management on their Managed Life models. These models allow the user to specify an acceptable write threshold, and throttle the write performance accordingly to keep the SSD within its expected life curve.
SED and FIPS 140-2 compliant SSD models offer Seagate Instant Erase, cryptographic erase for easier drive repurposing and retirement, and the SANITIZE command.
