剛好最近有在整理SSD的資料: SD Adavantages: Faster startup – Since no spin-up is required. Far faster than conventional disks on random I/O. Extremely low read and write latency (seek) times. Faster boot and application launch time. Lower Power consumption and heat production. Pure Silence.(No moving parts) Better mechanical reliability.(No moving parts) Security(Quickly data wipe out) Constant Seek time(Less fragment seektime) Nearlly Waterproof(No moving parts) Lower weight and size(for lower capacity)
SSD Disavantages: Price(around US$8 per GB compared to about US$0.25 for mechanical drives) Vulnerability(magnetic fields and electric/static charges) Limited write cycles(100,000-300,000 write cycles) Slow random write speeds. Speed advantage of SSDs can be overcome by RAID setups of conventional HDD.
