While SLC (single-level cell) NAND Flash memory chips are known for their performance, reliability and high cost (hence why only enterprises can afford them), the cheaper MLC (multi-level cell) are used for consumer SSDs.
Innodisk decided to try and combine the assets of both, and the result was iSLC memory.
Though made out of high-quality MLC chips, iSLC uses a special, in-house firmware that provides reliability and performance, as well as endurance, almost on par with SLC.
More precisely, InnoDisk claims a 70% advantage over MLC, and endurance of 30,000 Program/Erase (P/E) cycles (longer lifespan).
Innodisk thinks its iSLC (patent pending) will perform well in industrial applications, kiosks, POS (point-of-sale), etc. Devices made with it will debut in the second quarter of 2013.
