"Our customers depend on ADLINK to provide a total solution in a ruggedized format that is able to operate under the most demanding environmental conditions," stated Stephen Huang, VP of the Industrial Computing Product Segment of ADLINK. "The ADLINK industrial grade ASD SSD Series provides customers with the high data transfer rates of the SATA 6 Gb/s interface, high reliability and long product life (up to 2 million hours MTBF) in an industrial grade storage solution."

Anobit sources vital analog IP for SSDs

Editor:- April 12, 2011 - Anobit today announced it has licensed IP cores from Cosmic Circuits for several of its SoCs.

The analog IPs which consisted of linear regulators, a power-on-reset and a silicon oscillator (with integrated clock multiplier) were implemented in 65nm CMOS process. These IPs were integrated into Anobit's flash memory controllers to enhance reliability and performance.

Kobi Blechman, VP R&D at Anobit said, "We had a need for a diverse set of IPs, and were looking for a supplier who had proven expertise in each of these areas. Cosmic fit the bill perfectly. With the strong support provided by their team, we were also able to quickly address any integration issues, making the process smooth and seamless."

Editor's comments:- although this press release only gives partial details of the IP supplied (which relate to managing sudden SSD power loss) I'm also guessing that Cosmic's ADC technology might also be in the mix.

Anobit uses DSP techniques to get better discrimination of the state represented by stored charge in MLC flash. Sampling that charge itself is an error prone process - but the "disturbance noise" filtering of a DSP can produce more reliable results if you can improve the ADC's resolution or repeatability. Even a small incremental improvement or tweak in design at this end can produce dramatic increases in data integrity.

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.

the Problem with Write IOPS in flash SSDs
the "play it again Sam" syndrome

Flash SSD "random write IOPS" are now similar to "read IOPS" in many of the fastest SSDs.

So why are they such a poor predictor of application performance?

And why are users still buying RAM SSDs which cost an order of magnitude more than SLC? (let alone MLC) - even when the IOPS specs look similar.
