80-gbyte Ssds Provide Fast Access Times, High Mtbf

摘要

The X18-M and X25-M SATA solid-state disk drives are built with multilevel cell (MLC) NAND flash and provide boot-up and program loads up to nine times faster than an HDD. The SATA revision 2.6-compliant 1.8-or 2.5-in. mounting form factor units come in 80- and 160-Gbyte capacities and target laptop, embedded, and desktop computers. Their typical power consumption is 150 mW average (PC workload) and 60 mW in idle. The 80-Gbyte drive is said to have an MTBF of 1,200,000 hours, with up to 250-Mbyte/s read speeds, up to 70-Mbyte/s write speeds, and 85-μs read latency.
