TDK mentions in recent SSD market history

August 2007 - TDK announced a joint venture with PQI to research, develop and market Disk on Module (DOM) and Solid State Disks (SSDs).

In May 2009 - TDK launched a range of 2.5" industrial temperature SATA SSDs (SLC and MLC) with upto 64GB capacity and R/W speeds of 95MB/s and 55MB/s respectively. Other features include 15-bit/sector ECC, 128-bit AES encryption and SMART. The new SSDs include internal UPS and an auto-recovery function that automatically recovers data when read disturbance errors occur. The company also launched a range of 1.8" SSDs.

In March 2010 - TDK launched the SHG2A series of half slim, encrypted industrial SATA SLC SSD modules with upto 32GB capacity and R/W speeds of 95MB/s and of 55MB/s respectively. ECC is 8 bit/sector (512 byte) correction (15 bit/sector correction). Endurance is 100,000 write cycles per block address (6.3 billion writes for a 16GB model). TDK has a life span assessment tool which enables customers to monitor the life span of these SSDs in their systems.

In March 2012 - TDK announced imminent shipments of a new SATA SLC SSD on chip. The company's eSSD series provides 1 to 4GB encrypted capacity in a 17mm x 17mm 208-ball BGA package.

fast erase / purge MIL SSDs
The need for fast and secure data erase - in which vital parts of a flash SSD or its data are destroyed in seconds - has always been a requirement in military projects.

Fast Purge flash SSDs directory & articlesAlthough many industrial SSD vendors offer products with extended "rugged" operating environment capabilities - and even notebooks SSDs come with encryption - it's the availability of fast destructive data purge which differentiates "truly secure" SSDs which can be deployed in sensitive applications.

Who makes these SSDs? How do they work? And what are the characteristics and limitations of the various methods used? Click on the link above to find out more in my special article / directory about fast purge SSDs.

Surviving SSD sudden power loss
Why should you care what happens in an SSD when the power goes down?

This important design feature - which barely rates a mention in most SSD datasheets and press releases - has a strong impact on SSD data integrity and operational reliability.

This article will help you understand why some SSDs which (work perfectly well in one type of application) might fail in others... even when the changes in the operational environment appear to be negligible.

How big was the thinking in this SSD's design?
Does size really does matter in SSD design?

By that I mean how big was the mental map? - not how many inches wide is the SSD.

The novel and the short story both have their place in literature and the pages look exactly the same. But you know from experience which works best in different situations and why.

When it comes to SSDs - Big versus Small SSD architecture - is something which was in the designer's mind. Even if they didn't think about it that way at the time.

flash SSD capacity - the iceberg syndrome
Have you ever wondered how the amount of flash inside a flash SSD compares to the capacity shown on the invoice?

What you see isn't always what you get.
