Hi, the hard drive on my 2008 iMac just died. I was considering getting a 1T SSD, but it's so darn expensive(>$600.00 USD!, OUCH!!) For an old iMac, I am not sure if it's even worth to spend that much.. My next option is getting a hybrid SSHD. I am looking at this Seagate 1TB Solid State Hybrid Drive SATA 6Gbps 64MB Cache 2.5-Inch ST1000LM014 from Amazon, the price is rather affordable. However, I have never used a hybrid SSHD before, I have two questions: 1. Would OSX recognize it as one drive? I cloned the entire disk from the dead HD for safe keeping, if I understand correctly, if I clone the backup drive to the SSHD, it should just be the same as the dead boot HD 2. How much performance gain I get with a SSHD vs. a run of the mill 2.5" HD? Thanks in advance.
