Super slow SSD in all operations
Macbook Pro 15" Unibody 2.53 GHz Mid 2009
I have three Macbook Pros I use, and had to swap the drives around. In April my old one (pre-unibody 2008) had a hard drive failure so I replaced it with an SSD (Sandisk Ultra Plus). It worked great. Now I'm switching drives around to use the new faster Unibody 2009 MBP with the information on that old MPB's SSD.
Maybe this was stupid, but I was hoping I could just pop the SSD drive in the 2009 and it would work (same OS, Snow Leopard, on both). It actually did boot up and ran all my apps, but very slow! I got the spinning beach ball non-stop. Next time I tried to boot it failed.
So, I tried re-installing the OS from scratch with the SSD in the 2009 MBP. I tried several times and the installation was just taking so long I shut it down. I am currently running Erase again in the disk utility and writing everything to zeros. So far it is about 1/3 done and it's been going for 1/2 hour. This is only a 128GB drive!
It seems like every operation that accesses the SSD from this MBP is super slow. I don't think the problem is the drive. Just yesterday it was working perfectly in the 2008 MPB. I've also read some stuff about faulty SATA cables in the 2009's. I haven't tried any firmware updates or TRIM settings, since I can't even get the OS installed. Not sure what to try next. I can't afford another drive right now.
Is this a good question?
