Hello everyone, I first installed my Samsung 830 SSD about a year ago. I have loved the performance and speed since day one. I had always experienced boot times of approximately 12 seconds. Recently, I noticed that boot times had seemed much longer, about 45 seconds. Moreover, shutting down took well over a minute. After some hunting around, I did a PRAM reset (no difference) and cleared the the kext caches (boot times reduced to about 30 seconds, shutdowns still slow). I am not sure what the deal is. I doubt a year of casual use has degraded my SSD, so I think some setting is screwed up somewhere. I don't know exactly when the boot times started slowing down, but I only recently noticed it. I have upgraded to Mavericks (so that could be one culprit) and recently downloaded Chameleon SSD Optimizer (before, I only used TRIM Enabler but decided to go with Chameleon since it offers additional functionality). Any thoughts on what the issue might be? I have the correct start up disk selected and confirmed the start up disk after clearing the kext caches. Thanks in advance! Edit: Here is a screen shot of a speed test in case readers find it helpful. Note, I am on a mid-2009 MBPro (SATA 3gb/s).
