In 2012, I debated whether it made sense to replace my early 2008 MBP's HDD with an SSD. I decided that it didn't, so, last January, I bought a refurbished Mac mini i7 2.3 GHz. I've been very happy with it, and it's my main Mac. Since my old MBP didn't have much resale value, I decided to keep it, and I still use it for tasks that don't require heavy lifting. I was surprised and pleased to find that Mavericks is supported, and that the computer is still useful. Anyway, it's nice having a laptop as a backup -- and, since I can't justify buying a new MBA or rMBP for a couple more years, I'm once again considering replacing my MBP's HDD with a 256 GB SSD. I read a recent post by one person who did this and said he didn't notice much of a speed increase, and said he wished he'd just installed a cheaper 7200 RPM 1 TB HDD instead. I currently have a 7200 RPM 320 GB HDD in mine, which is more than enough storage for this old machine. That contradicts other posts from 2010 and 2011 that said an SSD provided a significant speed increase. I don't expect miracles, but a noticeable speed increase would be welcome. So has anyone here recently upgraded an older MBP with an SSD, or is anyone still using an older MBP that they upgraded a few years ago? If so, would you recommend it? I'll probably keep my old MBP until it dies or become unusable.
