Innodisk Innovates on NAND Flash to create iSLC Flash Technology

Innodisk, a designer and manufacturer of SSDs for industrial applications, is pleased to announce its development of a new patent pending technology, iSLCTM. By using superior quality, preselected multi-level cell (MLC) NAND Flash and Innodisk's patented Flash management algorithms, iSLC nearly approaches single-level cell (SLC) performance and reliability in a more cost effective solution.

In a recently released white paper, Innodisk explores MLC NAND Flash; while more economical, it lacks the reliability and performance needed for mission critical industrial applications. MLC's popularity has been mainly driven by price. Innodisk's in-house R&D firmware team recognizes the gap in the marketplace for a Flash Storage solution that maintains high performance, reliability and endurance comparable to SLC Technology, but without the price tag. To provide a solution for this gap in the market, Innodisk developed iSLC.

iSLC technology reprograms the two bits per cell of MLC into one bit per cell, which increases the sensitivity delta between each level. This practice enables the NAND Flash to perform similar to a SLC Flash-based solution. The average endurance of iSLC can surpass 30,000 Program/Erase (P/E) cycles, which increases the lifespan of the drive over MLC Flash by a multitude. Additionally, write performance for iSLC is about 70% faster than MLC on SATA II.

Innodisk has designed iSLC to perform as close as possible to SLC Flash, with a price point similar to MLC Flash-based products. This technological development offers a cost effective way for industrial applications, such as kiosks and POS, to perform at a high capacity while still keeping a tight control on expenditures.

Innodisk has iSLC integrated into many of the SATA II product lines. SATA III (6.0Gb/s) iSLC products will become available in the second quarter of 2013.

Uh oh, a lower case "i" in front of a name... Hope Apple doesn't find out! :nutkick:

Interesting numbers in that graph.

Interesting in that there's a lot of bullshit. Based on a 32 GB SSD with 10x its capacity written to it every day?

These are intended for industrial use where reliablility is of major importance.

some servers will do more than 10x in a day and they're purposefully going over the top to ensure quoted numbers apply even in the most extreme scenarios.

By and large it shows that MLC is more than enough to the average joe as it'll run 8 years writing the full capacity of the disk each day. Which is extreme for an average user.

but my company does online education. we add content on the fly and at any given second, the servers are writing several GB of new content. Our production servers only get updated weekly, but the dev servers, those ones get pegged all day long every business day. We can easily benefit from iSLC.

Yeah, not disputing that, but on a 32GB SSD? It skews the figures so much.
