Seagate to Offer Solid State Drives in 2008
Lucas123 writes "Seagate will introduce drives based on flash memory in various storage capacities across its range of products including desktop and notebook PCs, according to Sumner Lemon at IDG News Service. The drives are expected to consume less power (longer battery life), offer faster data transfer rates and be more rugged than spinning disk, which has moving parts that can be damaged from an impact."
The speed of sequential access is about the same for HD and flash.
Flash is better for random access which is not very important for end-user, that's why end user doesn't care about SCSI, since for them HD is just storage as it supposed to be.
Kernels/filesystems/application aren't just prepared to use the "power" of flash. What's the point of having flash as a disk cache if RAM already does that?
I don't see where the "most used" algorithm of flash disks is different from those used for RAM, so you happen to have a lot data cached twice for no purpose.
RAM is way faster than Flash and 64bits processors give a big limit (32GB) of RAM/processor. Flash is cheaper but, as said, much slower, flash disks will be as commom as buying a 36GB 15k HD to use as cache of your 750GB 7.2k
