"Intel SSDs and TRIM in 2011 MacBook Pro
I just wanted to drop you a quick note to mention that I'd used the TRIM driver hack described on your site to enable this on my new 2011 15" MBP.
Initially with my Intel X25-M G2 SSD recycled from a prior laptop until I could get one of the new generation it reported "No", which surprised me until I realized that I'd never upgraded the firmware from the original (pre-TRIM) version that came with it. The perils of being an early adopter. Intel's firmware update ISO won't run on the 2011 MBP, so I just lived without TRIM for a month or so, and saw no difference from the way the SSD had worked on the old 2008 MBP, other than the whole system being faster of course.
Last week, I replaced that with an 300GB Intel 320 (INTEL SSDSA2CW300G3) and it showed up as "Trim: Yes". I used CCC to copy the old SSD to a firewire disk, and then back onto the new SSD after the swap.
So far its working fine, and the performance is perceptibly faster than even the X25 was, although I haven't formally benchmarked it.
The X25 had run well for ~18 months as my sole disk, in daily use for 8-10 hours with about 10-20GB free (a real stress test for an SSD) and the only problems ever observed were rare situations where it took a long time to complete a disk operation and some application noticed and reported an error reading (usually) a file.
The real proof of whether TRIM improves that will take months, and I'm never going to run this disk 90% full so it won't get as much of a stress test. But after one week of daily use, it's been rock solid, no observed problems whatsoever.
FYI: I've also enabled the "noatime" fix and set the disk to never sleep (although I never observed any issues either way on the old disk, which ran part of its life without those and part with). My laptop is set to never sleep as I just shutdown when not in use (which is really fast), so I've never encountered any of the sleep issues
some people have reported.
I've been a long-time reader, and always found your site informative and helpful. Keep up the good work.
