New processor boosts SSDs
SANDFORCE has released details of a new SSD controller which it claims can force SSDs to 250MB/sec worth of sustained reads and writes
The outfit said that its new range of SSD processors will allow lower-cost, commodity NAND flash memory to be used in data centres. Apparently, they make disks go like the clappers and more reliably.
The controllers allow multilayer cell NAND flash memory to take the place of single-layer cell memory in data centres. If it works, it will cut the cost per gigabyte of capacity by three or four times.
Dubbed SF-1000, the SSD processor series, with its DuraClass firmware should fix problems with the endurance, reliability and data retention issues associated with MLC NAND flash, the outfit said.
Samples will be available later in the second calendar quarter of 2009. µ

Whom Spread Rumour That SSD Had BAD First Break? NOT ?Ultee',Hummmm. Heres opinion:SSD growth has been hindered due to confusion and concerns regarding endurance, reliability, performance and prices”, Oh, Just Tort Me, Winkie. AnyWay theres Lots of NEWNESS Here. Read Article, 250 Mb/s IS FAST for ANY system. RAISE™ (Redundant Array of Independent Silicon Elements), which deliver an orders-of-magnitude improvement in drive reliability versus today’s SSDs and enterprise HDDs. Allows R.A.I.D. on One SSD.Ahso, Controller referred to as Processor, So Thats Good. Out with High Watt Low I/O failure of recent & this quarter, In With Better Shot. Drashek
These wonderful press releases from companies don't mean very much if the customers (business or consumer) is not able to see such claimed awesome-ness in action!...As in reviews from third-party sites.
This is all talk.
I want them to prove it!
Better do your homework, Nick. It is called "multi-level" cell, because one cell can store more than 2 states. Means cheaper, but also less reliable and less write-cycles. Therefore the controller has to take care of the wear of the cells.
If you don´t know about it, don´t write about it.
"wear of the cells"
The very thought of the cells that hold my valuable data wearing out , makes me shudder(and not want to buy SSD yet).
They don't 'wear' out in the tradional sense. All that happens is that you will eventually no longer be able to write new data, existing data doesn't disappear, just new data can only be written so many times.
Either way it would still have to be under pretty heavy usage to even get to that point.
