Worth upgrading hard drive to SSD?

Hi all,

I have a MacBook Pro 15" Unibody 2.53 GHz Mid 2009 with 4 GB of RAM and a 320 GB 7200 RPM hard drive. I'm wondering if it is worth replacing the hard drive with a SSD. I've noticed significant performance degradation in the last 6 months and I'm hoping this will help enough to get another year or two out of this computer. What kind of performance increase could I expect with a new 256 GB SSD? Would upgrading to 8 GB of RAM help?


Answer this question I have this problem too

Is this a good question?

How much space do you have left on current HDD? What do you use your computer for?

Upgrading RAM always helps performace… but you must have free space left on the HD to support the VMEM and swap files. ~20% of the size of the drive or in your case 64GB free space. If you don't have that much free space now… that could be why it' running slow.

SSDs are fast at booting … otherwise, not so much.

Expand upon performance degradation.. when you notice it what is going on.
