We have the outstanding ability for choosing the best MLC Flash memory, and we know how to use our proprietary firmware technologies to allow our iSLC products to perform at almost the same level as SLC-based products with reliability and service lifetime

Innodisk, a designer and manufacturer of SSDs for industrial applications, is pleased to announce its development of a new patent pending technology, iSLC. 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.
