[QUOTE="RadDave, post: 1643533, member: 234411"] Hi [B]All[/B] - I've been enjoying this thread (thanks [B]Lisa[/B]) and have a basic understanding of TRIM and also have looked at a number of the links. BUT am curious as to several issues involving my own MBPro's SSD and also about TRIM. I have an early 2011 r-MBPro w/ the system info on the SSD shown below - my drive is defined as an [I]Apple SSD SM256E Media[/I] - not sure if this is an Apple SSD or something Apple bought from a third party? This laptop started out on 10.8 and is now on the present Yosemite OS - I have no idea how TRIM even applies to my machine and I've done nothing regarding adjusting this function or using TRIM enabler (if even needed)? My other question concerns the ability to retrieve 'trash deleted' data w/ disk recovery software (a common question on this forum) - if TRIM is NOT being used then deleted data may still remain on the drive for a while (until overwritten) and possibly be recovered; if TRIM is used, then these pages/blocks are cleaned up quickly and thus this deleted data is removed - SO, what is the best option? Just a few questions that I hope can be addressed - sorry to be a 'PAIN' but still a more matured NEWBIE at this point. Thanks - Dave :) . [ATTACH=full]21895[/ATTACH] [/QUOTE]
