SanDisk Focusing More On Desktop and Mobile SATA SSDs, Extreme II Series Tested

MojoKid writes "Odds are, if you've purchased anything that uses Flash memory in the last 20 years or so, you already own a piece of SanDisk technology. The company has been in Flash storage since the late '80s and manufactures products used in everything from smartphones to digital cameras. Even though it enjoys a long history in the Flash memory business, SanDisk is perhaps not as well known for its Solid State Drive (SSD) solutions for desktop and mobile PCs. However, SanDisk recently expanded their product stack with new, high-performance SSDs that leverage the company's own NAND Flash memory and Marvell's popular 88SSS9187 controller. The new drives are SanDisk's Extreme II family of SSDs targeted performance enthusiasts, workstations professionals and gamers. The initial line-up of drives consists of 120GB, 240GB, and 480GB models. Performance specifications for the three drives come in at 545MB/s – 550MB/s for reads with write performance from 340MB/s to 510MB/s, depending on density. In the benchmarks, SanDisk's Extreme II SSD showed it has the chops to hang with some of the fastest drives on the market from Samsung, Corsair and OCZ."

I can't vouch for the modern SSDs, but I've had an X25-M in my netbook for years, it's used every day, and it's now reporting that it's down to 99% of its write capacity. At that rate the netbook will be in a museum long before the SSD dies.

The X-25M had a write endurance of 7.5 TB for the 80 GB, and 15 TB for the 160 GB. If you've got the 160 and write an average of 100 MB per day, that's only 0.18 TB in 5 years, or barely more than 1% of the endurance. If on the other hand you wrote 10 GB a day (about two DVDs' worth), that would be 18 TB, and the drive would be likely shot. An HDD has infinite endurance. It can die from various failure modes, but not from "using up" the magnetic storage medium.

It completely depends on how much data you write.
