I STRONGLY second this. I have a Samsung SSD (which is the same SSD Apple uses). The performance degradation due to lack of TRIM is horrible. Get SandForce controller. You're fü+k3d without it...Get a drive with internal TRIM support.

With non SandForce controllers, you'll be manually refreshing your drive to emulate what TRIM does. (Granted, it's once every six months or so, but I'd rather not bother with the hassle if I were going SSD.)
I installed an OCZ 120 V2 SSD in my 2009 15 MBP and it is much, much faster. Very easy install and only took minutes.
I got an Intel X-25 M G2 160 Gb last October for my Macbook Pro 13". A year later, and the read speed is identical to what it was new: 255 Mb/s. Read speeds have only dropped slightly from about 95 Mb/s (new) to 85 Mb/s (old). This is still faster than a 2.5 rotating drive.
Go with the Intel X-25: you won't be disappointed.
Wait for the next generation Intel SSDs.
Whats the fastest speeds can a mbp achieve with sata 3?
Will it make a difference when new faster ssd's come out?
Whats the best SSD for a MBP for performance?
Faster than what, sorry?
Well SATA III is 6Gbps but I think the current MBPs are SATA II only, so 3Gbps. For best performance on a mac you need high random write speed and some sort of garbage collection otherwise it will deteriorate once all cells have been written to.
I see and sorry I meant sata 2..
How fast can write speeds go up to from sata 2? as I want apps to load instantly on click.
I've heard that the third generation of the Intel SSDs aren't that huge of an improvement...
