SSDs have largely been too tiny (in terms of storage space) and too pricey to take seriously -- at least, for everyone except those willing to pay substantially more to ride the cutting edge. But Other World Computing just threw a monkey wrench into the norm, dishing out an incredibly roomy 480GB Mercury Extreme Pro solid state drive meant to supplant your aging laptop HDD. It's one of four in the range (60GB, 120GB and 240GB models are also available), all of which are pegged to deliver up to 285MB/sec sustained data rates with "no speed degradation." All four sizes are up for pre-order now for both PC and Mac platforms, with prices set at $219.99 (60GB), $379.99 (120GB), $699.99 (240GB) and $1,579.99 (480GB). What, you expected 480 gigabytes of sweet, succulent flash memory to come cheap? Puh-lease.
