so i got myself a new MBP... BTO, 2.3GHz i7, 8GB, 500GB @ 7200 rpm, 15-inch Hi-Res Antiglare Widescreen... I bought a OCZ Vertex 3 IOPS Max 120Gb to replace the HDD, which went in the place of the optical drive via a OptiBay. OS & apps reside on the SSD, user profile as well, with Documents, Photos, Music, Video linked to folders on the HDD. This way all the app settings can be on the fast drive, while the documents that take lots of space are on the HDD. The mac boots in about 20-25 seconds (to the login screen) then another 10-15 seconds to load the apps from the last session... The performance of the SSD is quite impressive, but the HDD is .... well.... disappointing... Or at least I think it is.... Can anyone tell me if there is smith wrong with it, or indeed it's supposed to be that slow ? SSD performance HDD performance (in the OptiBay) On a second note, what are the benefits (if any) to enable TRIM for the SSD ? Thank you.
