2. INTRODUCTION
The AT3550 “Wolverine” is a series of IDE solid state drives available in a low-
profile 3.5-inch format. The drive is completely solid state, making it exceptionally
rugged and able to operate in extreme environmental conditions.
Sector Erasable NAND E2PROM (Flash) is used to provide over 60 Gbytes of
nonvolatile, solid state storage in an extremely small, rugged form factor. The
drive is 100% IDE compatible and requires no special drivers to operate. It is
essentially a drop in replacement for standard rotating media.
The IDE interface is implemented using a commercially available IDE controller. It
supports UDMA-66 transfers, LBA mode addressing, and incorporates a 1 Mbyte
buffer, and a 16-byte hardware error detection and correction logic. The
CRC/ECC circuitry, in conjunction with Memtech’s proprietary Active Remap™
technology, makes for a virtually bulletproof medium for data retention.
The drive is available in a number of standard capacities ranging from 1 to 60
Gbytes. Drives under 12 Gbytes are 16mm tall, while 60 Gbyte capacity drives
are under 35.5mm.
Each drive is fully tested under environmental extremes at the factory using
Memtech’s proprietary EnduroTest™ to guarantee data integrity in even the
harshest conditions. Full functionality of the product is guaranteed out of the box.
