The MegaRam-35's lightning fast access time allows it to support over 120/I/Os per second.

The MegaRam-35 includes an SCSI-2 interface which supports transfer rates of 10 megabytes per second, and is a full featured solid-state disk offering optional internal battery and disk backup modules and built-in diagnostics. …
