Message Text: TDK has developed the mSATA SMG3B series of SSDs with support for 3 Gbps serial ATA. The products will be available from July 2012.

Designed for industrial applications, the SMG3B series drives measure only about 30 mm x 50 mm and offer storage capacities up to 64 GB. The mSATA implementation achieves actual read access speed of 170 MB per second and a 70 MB/sec write speed. The mSATA standard, established by the Serial ATA International Organization (SATA IO), was initially adopted mainly for digital consumer products such as tablet computers and netbooks. Because of its space-saving advantages, the standard is now gaining increased acceptance also for social infrastructure equipment and smart grid applications.

The SMG3B series uses the TDK original SSD controller GBDriver RS3 , featuring error correction expandable to 44-bit ECC. Data reliability has been enhanced thanks to a sophisticated power interruption data preservation algorithm and the auto refresh function. Another special feature is the data randomizer that varies data patterns during writing to reduce the risk of bit errors.

The SSD is using Single Level Cell (SLC) NAND type flash memory. Along with a global static wear leveling capability, the SSD achieves a storage life that meets the requirements of industrial equipment characterized by high usage frequency and long service periods.

The ATA standard security functions of the SMG3B series allow the user to set a password to counter the risk of data leaks, tampering, or unauthorized copying. AES 128-bit encryption used when writing data to the flash memory, makes it impossible to analyze data by reverse engineering. The ATA Trim command also allows complete data erasure which is vital when re-placing or discarding a drive.
