4 Product Specification
The Solid State Drive (SSD) is a small form factor 50.8mm x 29.85 mm x 3.3mm) non-volatile memory drive
which provides high capacity data storage. The SSDs are designed after the JEDEC MO-300B standard. It has a
standard combined connector with SATA and power/control part. The connector is mechanical identical with
eeePC card connector, but has different pinout. The card works at a supply voltage of 3.3V.
The drive with the SATA interface operates in Mode 2.0 (1.5 or 3.0 Gb/s burst).
The drive has an internal intelligent controller which manages interface protocols, data storage and retrieval as
well as hardware BCH-code Error Correction Code (ECC), defect handling, diagnostics and clock control.
The wear leveling mechanism assures an equal usage of the Flash memory cells to extend the life time.
The hardware BCH-code ECC allows to detect and correct 8 random bits per 528 Bytes.
The drive has a voltage detector and a powerful power-loss management feature to prevent data corruption
after power-down.
The specification has been realized and approved by the ATA/ATAPI-7 specification.

4.1 Physical description
The SSD contains a flash controller and Flash memory modules. The controller interfaces with a host system
allowing data to be written to and read from the Flash memory modules.
The SSD has a PCIe mini connector with SATA interface. Figure 1 and Figure 2 (page 39) show SSD dimensions and
connector location.

All values refer to Toshiba Flash chips (see part number) in UDMA5 mode (SATA 3.0Gbit/s) with Sequential write/read test (256
sectors multiple commands) and sequential and random write/read test (8 sectors multiple commands). Sustained Speed depends
on flash type and number, file/cluster size, and burst speed.
The typical random write speed values are really random access across the whole drive. Random write values in file systems are
much larger.
