In case you don't know what that is
"Whats the big deal with TRIM support? To put it simply, operating systems like Snow Leopard that dont have TRIM support will treat solid state drives as regular, spinning drives when writing and deleting blocks of data. Snow Leopard doesnt exactly know its dealing with an SSD, and while youll notice incredible performance improvements in daily usage, the same performances will slowly degrade over time without TRIM support. TRIM correctly tells the operating system which blocks of data are no longer in use in the solid state unit, and the OS passes the information along to the SSD controller so it can wipe blocks internally."
Hmm that's not good for the current MBA owners because neither the Toshiba (TSxxxC) nor the Samsung (SMxxxC) SSD's in currently shipping models support TRIM
Yeah but hopefully once Apple lets third parties sell aftermarket SSDs they'll support TRIM. Like the OWC ones, those ones support TRIM.
Actually, they do. You can tell if you check from within Windows in Boot Camp. The current version of OS X just automatically reports "No" for TRIM support.
You're right, sorry. I didn't realize the System Profiler just fakes it. That's great, it means a bit of a boost for the current-gen MBA's when Lion comes out (or at least they're less likely to suffer performance degradation).
Exactly this is great news!
MacBook Air SSD under Lion.
I'm sure the degradation is pretty minor and it's just overhyped here. If it were that bad, apple would have a crapstorm on their hands in a year. Wouldn't worry about it.
Its not as significant now as it used to be but its not exactly minor either.
Good news for us MBA 2010 owners... So when is Lion expected to ship?
