[QUOTE=oceanview7;2534808]Might as well start getting interested now since SSD’s currently have a longer life expectancy than hard drives. There are some various articles. Some think it’s less, but the point is that even if you filled an SSD with data 5 times a day, a typical SSD will last for about 52 years. They are usually rated for 100,000 write cycles. That means you could fill the drive fully 100,000 times. And yes, there are articles explaining this. And no I don’t remember where I saw it, nor will I google for you.[/QUOTE]Welcome to the forum.
We have a good deal of articles right here on this site regarding SSD.
50nm SLC NAND has approx 100,000 write cycles.
34nm SLC NAND has approx 60,000 write cycles.
50nm MLC NAND has approx 10,000 write cycles.
34nm MLC NAND has around 5,000 write cycles, and requires NAND over-provisioning to make sure the drives will last the expected life cycle.
25nm MLC NAND will have around 2,600 write cycles, and will require even more over-provisioned NAND to last the expected life cycle of the drive.
We are now also seeing very smart SSD controllers, such as the SandForce SF1200 and SF1500, which use technologies such as DuraClass to keep write amplification as low as possible.
