manufacturer model description......................
Hyperstone A2 family of
Flash Memory Controllers
Hyperstone's A2 family of SSD Flash Memory Controllers targets applications such as 2.5" SATA SSDs, 1.8" SATA Slim SSDs (MO-297), mini-SATA modules (MO-300), CFast™ Cards (CFC) as well as embedded Flash,

The A2 controller together with firmware provide highest reliability, endurance, and rigorous fail-safe features for all SLC and MLC NAND Flash Memory. This new family has emerged from the previously announced cooperation between Hyperstone and Toshiba Electronics Europe (TEE) regarding design, intellectual property, foundry and manufacturing services.
  • Fully compliant to SATA 2.6 and CFast 1.0 specifications
  • Hyperstone patented firmware architecture without need for external DRAM
  • Up to 150 MB/s sustained read performance
  • Up to 130 MB/s sustained write performance
  • Up to 600 4K random write IOPS
  • Host data transfer rate of up to 300 MB/s
  • Native Command Queuing (NCQ)
  • Power down detection for increased power cycling robustness
  • Typical active current consumption at 25°C with 100% utilization during stress test operating 4 x 3.3V NAND Flashes of about 250mA
  • SATA partial/slumber (about 150mA) and CFast PHYSLP (about 5mA) power modes supported
  • Qualified to industrial temperature range

Life isn't fair - if you design low power SSDs

by Zsolt Kerekes, editor

The curious thing for me is how the SSD market reacts differently to 2 different diemensions of SSD design:- speed and power consumption.

Designing the fastest SSD or the lowest power SSD are both difficult design tasks. And in some ways the "lowest power" design is harder to achieve - because there's less slack in the budget in the selling price set by the product marketers and the systems in which low power SSDs are used tend to be unfriendly compared to cushie server cabinets.

A low power design has to work with very ropey power supplies and often under severe temperature and vibration stresses too. And if the low power SSD fails - it doesn't have the luxury (like the fastest SSD) of being wrapped around with a protective RAID like cushion.

Yet despite all these difficulties for the designers of low power SSDs - the market hardly notices when a new model is announced that takes 30% less watts - whereas all the news-feeds go wild when an SSD company beats an IOPS benchmark record by a similar amount.
