2. INTRODUCTION
The SC35 series is a line of 100% compatible SCSI-II solid state drives in a
3.5-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) in 128 Mbit to 1 Gbit
configurations are used to provide up to 27648 Mbytes 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 SC35 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
53C90A SCSI-II processor. The microprocessor performs all power up
diagnostics, data transfers, and error handling in the unit. The SC35 can
sustain a 1.5 Mbyte per second read throughput and 650 Kbyte per second
write throughput. The unit responds to all Direct-Access device commands,
and as with all single-ended SCSI units, the SC35 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 27648
Mbytes. 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.
