Best COMPATIBLE ssd for NVidia MCP79 chipset?

I'm having a **** of a time searching for an answer.

I recently purchased a Toshiba Q Series SATA3 SSD, only to discover my MBP will negotiate it at 1.5 Gigabits only. That's when my crusade began.

I've read that SATA3 is backwards compatible with SATA2. I've proven that false, at least with mine.

I've read that some SATA3 SSDs will indeed work with MCP79, but I've only found hearsay, not real people who have done it and guarantee it.

I've been looking at SATA2 SSDs, but the ones I've seen benchmark well below 3 Gigabits... so what's the point?

Hi Guys! for those attempting to also answer this question like myself in 2017- I can confirm other users success with Samsung Evo 850. Since swapping drives (was using a Sandisk plus and was only pulling 1.5 Gigabit), my Mini has consistently negotiated 3 Gigabit on AHCI version 1.2. speeds and read and writes are somewhere around 225-260mbps.

Currently running on a Mac Mini 3,1 A1283 early '09.

I was getting similar speeds when I did not set up my computer as a RAID 0 but once I got two SSD in Raid 0 I manage to triple the amount of speed

when you boot to in recovery mode you choose the pen drive not the hard disk. I forgot to mention that.

Correct you would get Sata 2 only and you would be able to use FileVault and it will have a partition for you to do boot recovery......

now when you do a striped raid and put the highest Kilobyte block for max speed you would get Sata 3 speed.
