2. INTRODUCTION
The SC2500 series is a line of 100% compatible SCSI-II solid state drives
in a 2.5-inch half-height format. It is completely solid state, with no moving
parts. This accounts for the unit’s exceptional ruggedness and wide
operating temperature range.
Sector Erasable NAND E

PROM (Flash) are used to provide up to 9 Gbytes
of nonvolatile, solid state storage in an extremely small, rugged form factor.
The drive is 100% SCSI compatible and requires no special drivers to
operate. It is essentially a drop in replacement for standard rotating media.
The SC2500 can be used in applications where operating conditions are
harsh and when reliability is critical. A 100% CMOS logic design minimizes
power consumption, and the +5 volt only power requirement simplifies
system supply needs, as +12 volts is not necessary. An on-board
microprocessor implements all control functions, and oversees SCSI
communications via a QLogic FAS209 SCSI-II processor. The
microprocessor performs all power up diagnostics, data transfers, and error
handling in the unit. The SC2500 can sustain a 7.0 Mbyte per second read
throughput and 1.5 Mbyte per second write throughput. The unit responds
to all Direct-Access device commands, and as with all single-ended SCSI
units, the SC2500 may be placed up to 18 feet (6 m) from the host SCSI
controller. Data integrity is maintained using Memtech’s proprietary Active
Remap™ technology.
The drive is available in capacities ranging from 128 Mbytes to 9 Gbytes.
Please contact the factory with your requirements. Disk compression
utilities may be used to effectively double the usable capacity of the drive.
Every drive is fully tested under environmental extremes, which guarantees
data integrity under even the harshest conditions.
