2. INTRODUCTION
The SC3500 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) are used to provide up to 36864 Mbytes of
nonvolatile, solid state storage in an extremely small, rugged form factor. The drive
is 100% SCSI-2 compatible direct access device and requires no special drivers to
operate. It is essentially a drop in replacement for standard rotating media.
The SC3500 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. 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
SC3500 can sustain a 2.3 Mbyte per second read throughput and 1.0 Mbyte per
second write throughput. The unit responds to all Direct-Access device commands,
uses a single-ended, unitized 50-pin interface and as with all single-ended SCSI
devices, the SC3500 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 36864 Mbytes.
Please contact the factory with your requirements. Every drive is fully tested under
environmental extremes using Memtech’s Enduro Test, which guarantees data
integrity under even the harshest conditions.
