In my opinion it's like all other gadgets ... only some of them deliver an added value. SSD-Disks deliver some really good values:
- shock resistance - power consumption - speed the first two values are important for mobile devices - speed is a nice sideeffect. But have in mind, that all ssd's have a limited lifetime - especially multilevelcell SSD's. If you use multiboot environments keep in mind to optimise your OS for using SSD's. Windows 7 with ntfs use trim-function implemented in newer SSD-Controllers like the Indilinx Barefoot-Controller for wear-leveling the cells. OpenSolaris with ZFS uses copy on write and distribute the block-writings. But it don't balance the blockwritings on the whole disk like the trim-function does. I know that trimming the cells has negative aspects (speed, queueing, overhead) but it improve the lifetime of the ssd-disk (multilevelcells = 10'000 singlelevelcells = 100'000 writes) by eliminating 'hot spots' on disk. An interesting Thread about this: http://opensolaris.org/jive/thread.jspa?threadID=112305&tstart=75 So digg first for the ssd-technology before buying... Kind regards G?rald
