I completely agree. Not a derailment at all. My goal for the thread was to unite lovers of these old machines.
For those that have done a hard drive upgrade, how difficult was it and how much did the upgraded hard drive cost? Also, do you have any recommendations for brands or websites to order from? I'm still using my original hard drive. An upgrade might be helpful.
Oh, Gawd, yes. I've upgraded mine several times- first for capacity, then for speed. Over the years, I have used first the Seagate hybrid SSD/spinner, which helped a great deal with perceived speed, and then just went with the same Samsung SSDs I was putting in my other machines (volume discount, you know). The difference between an older MBP with a spinner and one with an SSD is pretty stark. If it didn't smell like hell warmed over and have all these scorch marks, a flickering backlight, and a dead touchpad, I'd keep it forever...
If you squint a little bit, is is easy to justify picking up a max memory upgrade and an SSD. A true beancounter will tell you that it is a waste of money- but if you love the old beast, and it still fulfills your usage case, you'll marvel at the improvement.
The memory is relatively cheap now, since nothing else really uses it anymore: the 2.4s need 1066MHz DDR3 ECC SDRAM (PC3-8500), the faster ones need 1333. The SSD is essentially a lifetime investment: even if you eventually decomission the MBP, you can pull the disk and put it in an external enclosure. 1TB SSD SATA drives are under $100 these days, and you really don't need the bleeding edge of technology, with the MBP's relatively slow 3GB/s SATA bus. Doesn't matter- anything will beat the original spinner.
You could do both upgrades in half an hour, tops, if you are the least bit mechanically inclined. Replacement/upgrade of either one is trivial with the right tools. These machines were designed before Apple decided to make them a pain in the ass to upgrade, and there are many YouTube videos describing the process. My advice would be to dive right in!
