HGST Ultrastar SSD800MM Specifications
The dual-port 12Gb/s SSD800MM weighs in with sequential throughput of 1,200/700 MB/s read/write, and 145,000/70,000 sustained read/write IOPS provided by 25nm Intel eMLC and the HGST/Intel DB29AA11AB0 controller and firmware.
With a focus on lowering TCO via low IOPS-to-Watt ratios (tested in the following pages), the HGST Ultrastar SSD800MM features two modes of operation to streamline the SSD for either performance or efficiency. The SSD800MM operates within different power consumption envelopes, with a 9 Watt and 11 Watt mode available. The SSD800MM features a capacitor for power hold-up in the event of a host power-loss issue and advanced power loss data management technology.
The SSD800MM operates in either 6Gb/s or 12Gb/s Active-Active dual/single port to provide enhanced reliability. The SSD incorporates the T10 Data Integrity Field (DIF) standard, extended ECC, and Exclusive-OR (XOR) parity to protect against flash die failure. Parity checked internal data paths protect data as it moves within the drive, and the SSD800MM does not use an external write cache. These technologies combine to provide the SSD800MM with an IE-17 non-recoverable error rate. A 2 million hour MTBF, and 0.44% AFR (Annualized Failure Rate), round out the reliability specifications.
The SSD800MM also comes with three levels of encryption support. TCG (Trusted Computing Group) encryption, TCG + FIPS 140 encryption, and Crypto Sanitize capabilities round out encryption support.
The SSD comes in a 2.5" form factor with a 15mm z-height and is available with a five year warranty in capacities of 800, 400 and 200 GB.
