So last year i tried to install an SSD twice into my Late 08 MBP 2.53GHz 4GB Started with.. Vertex 2 was too unstable lots of the usual problems. Then tried the OWC Mercury Extreme Pro, less so problems but still a nightmare when actually installed in the computer. Worked fine when mounted externally though usb. Both i have since found out have had a few general issues. I'm not too fussed about super amazing speed performance etc etc, i just want it to work the Vertex and OWC are meant to be fast, but they're not fast when they dont work on my MBP?! Are there any current SSD's that just work and have always worked? They must be some, because even back when i bought my MBP in 08 i could have got an SSD from Apple put in it. So which are known to work but are not as amazing than others? I've cannot seem to find anything wrong with the Crucial RealSSD C300 that a good suggestion? Regardless of speed here and there any SSD is going to be quicker and smoother than my current HDD surely?
