anyone considering an ssd to be slow at all does not have a clue or yet used one. it's the single fastest thing you can get for your pc. it has a random access time of 0.065ms, compared to 8ms on the fastest drive (raptors). that's more than a 100x faster in random accesses, which happen to be most of the stuff your os ever does.
even when it's degraded, it still dances around any hdd in performance. it's the internet, every bad thing gets dramatized and overcried.
and, the difference from a hdd to an ssd is amazing in terms of silencing. i have pc's i don't even know if they're on or not. other pc's suddenly have their screen-fan annoyingly loud as they got silent (yes, screens have fans, too, iehk.. at least my 24" screen does).
it's the single best thing you can buy for your pc, worth the 400+$ easily for the 160gb drive. i know most won't believe me. you should still do so..
in other news, for the data storage needing guys, get a windows home server, put your disks there. make it as quiet as possible, and put it somewhere away so you can't ever hear it. the home server is awesome in tons of situations, from automatic backup of all your systems to networked shares with data duplication and all, user management etc.
mine is built into some ikea furniture (can't post pics yet), silenced except for the hdds (but they're quiet ecodrives).
investement in the server + the ssds for all the pc's: around 1000$ all in all. gain in noise reduction, performance enhancement, storage size growth, + the autobackup taking away any fear of problems, definitely worth it.
worth it over any other investment in computing i've ever done.
and this was my first post, pure marketing
sorry. i just had to comment here.
