Toshiba offers mSATA and Half-Slim 30GB and 62GB SSD modules
SSD designers nowadays seem to be at their best, trying to outrun each other. The latest to join this bandwagon is Toshiba Corporation that revealed two new kinds of SSD modules crafted using the Toshiba 32nm MLC NAND flash technology. Each type of SG2 module is based on the mSATA interface standard or alternatively on Half-Slim standard which needs a SATA connector. Production of the drives will commence in October 2009.
The Half-Slim SATA-2 module has dimensions of 54mm x 4mm x 39mm and runs at 5V. It is JEDEC compliant and uses the same connector as the 2.5” HDD and SDD form factors. The mSATA-2 module connects to the operational system via the SATA connector and has dimensions of 30mm x 4.75mm x 50.95mm and runs at 3.3V. Both products have individual capacities of 30GB and 62GB, weigh in at 9g and operate with an interface of SATA-23Gbp/s.
Both types of SG2 modules consume 1.3W in read mode, 1.8W in write mode and 65mW in idle/standby/sleep mode. The maximum reading and writing speeds in sequential mode are 180MBps and 70MBps respectively. The MTTF of the systems is 1 million hours and they operate at 0-70 degrees Celsius. When not in read or write mode, the APM and DIPM system reduce electricity consumption to half or less than that of the device in read mode.
“Initial adoption of most SATA solid state drives has followed the HDD form factor. Our latest 32nm mSATA and Half-Slim case-less modules enable hardware designers to add the performance and reliability advantages of a solid state drive in a smaller, footprint for notebooks, portable electronics and other embedded storage applications,” remarked Scott Nelson, VP Memory, TAEC.
Each type of SDD boasts of smaller dimensions than a business card. The 62GB module occupies just 1/7th the space, has just 1/8th the weight and claims to eat up only half the power of a 2.5” SSD. The revamped controller features and translation mode further allows for any drive configuration. It supports 28-bit and 48-bit LBA, multi-word DMA, advanced PIO and ultra-DMA mode commands. Additionally, its FDE backup guards against illegal data access.
Both modules are designed to economize on space and cost. PCs makers on the look-out for SSDs that complement small dimensions with better storage ability may have found the answer in Toshiba’s latest offering.
The intended price tag of these modules has not yet been revealed.
