TDK Launches SDG2A Series Solid-State Drives

TDK Corporation announced today the launch in late May 2009 of the SDG2A series of serial ATA(SATA) II compatible industrial solid state drives(SSDs) with a maximum memory capacity of 64 GByte.
These products are industrial SATA Flash discs equipped with GBDriver RS2 SATA controller ICs developed by TDK. They support high-speed access with an effective read speed of 95 MByte/second and effective write speed of 55 MByte/second. They also feature powerful error correction capabilities scalable to 15-bit/sector ECC(error correction code), providing high levels of data reliability. The use of an internal power supply protection function prevents errors in the event of a power interruption. These SATA drives are also equipped with an auto-recovery function that automatically recovers data when read disturbance errors occur from repeated reading of data, making them ideal for use on automotive application such as car navigation systems.


TDK has achieved a substantial improvement in the life spans of semiconductor memory storage devices. An advanced static wear leveling function developed by TDK equalizes data writing among all of the Flash memory blocks, maximizing the life span of the memory. SMART(self-monitoring and analysis reporting technology) data makes it possible to determine the number of times each memory block is erased, facilitating quantitative assessment of silicon disc life spans in real time.

The drives also feature an advanced encryption function using the 128-bit AES encryption that has been registered as United States Department of Commerce Federal Information Processing Standards FIPS PUB197. Data is automatically encrypted before writing to the Flash memory, preventing data tampering and leaks. A high level of storage security is provided to prevent unauthorized copying and other data risks by using both ATA standard security functions and an original TDK password lock function.

TDK’s SDG2A series of industrial SSDs are SATA discs suitable as replacements for hard disc drives(HDDs) and provide high-speed performance, data reliability, storage life span, and data security at the highest levels in the industry. In addition to the 2.5-inch discs currently available, TDK launch the series of 1.8-inch SDG2A SSDs.

I think I'll leave the details of these out of my postcard. The automatic encryption may be useful for some people though. Maybe they can do better with their next generation..

5000x writes is a bit under par for MLC too isn't it?

5,000 writes under "active wear algorithms" is equivalent to 10,000 writes without active wear.

Nonetheless, that is NOT a wear level for a registry or pagefile UNLESS there is a big write buffer / cache, otherwise this thing is at risk of failing after a few years.

um... who would buy a 1gb SSD?

It would make a perfect pagefile/cache drive.

yeah, but then the 4GB would be better...

Am i reading that correctly?

those write speeds are AWFUL! D:

Hint: Not for the PC market.

^^ the man's a genius
Thanks for adding that screenshot.
Looked to me like its just a handy replacement for applications where an Embedded system used to use a CF card (via IDE) for OS storage.
A little less efficient in terms of volume and physical size, but plenty more storage space and horsepower (speed/IOPS).

Used to buy there tapes all the time and it be nice to see them progress into the PC market. Made me think of the D tapes rugged shame they will not be as cheap as those :P...

Ye - I'm STILL confused - why the make a SSD when you can just use an XD card?

They already exist, and read/write faster (In many of the size variants), And an XD card is smaller.

I just don't see why bother invent something that already exists... in a BETTER form?

Perhaps I'm just crazy... Wouldn't be the first time anyone said so...
