Guidocorona - I'm not sure if it's 2.5". The web site of the Other World Computing is www.macsales.com
OWC is the one of the best stores for mac - very helpful and customer oriented. Everything is high quality - they don't sell junk. I bought many things there. Look for Neptune external drive. I bought the Firewire only 500GB with Western Digital drive inside (now $114). I'm not big fan of Western Digital but this one is very quiet. You might ask them about Hitachi. Right now they have $30 rebate from Hitachi.
I also bought pocket 250GB USB drive for the laptop backup and it is dead quiet.
Initially all drives are formated for MAC but they accept NTFS - at least this pocket drive (case is clear plastic). Ask them since NTFS format is sometimes fishy and FAT32 is garbage.
