This is an article about my positive Mid-2010 MacBook upgrade experiences I had so far.
Earlier this year I bought 2x4GB DDR memory modules (1066 Mhz, DDR3), which really improved the performance of my “old” machine.
Since MacOS is made for multitasking, where you have many applications open at a time, it really relies on a sufficient amount of RAM. Originally, my MacBook had only 2×1 GB memory, so I went to Amazon and saw this $40 offer for good quality 2x4GB Kingston memory modules an ordered them right away. Upgrading the memory modules itself was very easy and took me not longer than 10 minutes. All you need is the right screwdriver – note that this upgrade won’t affect your warranty by the way.
After this little surgery was completed, I really noticed an increase in performance. I think the $40 was a really good investment. Unfortunately, if you order your MacBook at Apple with extra memory, it costs so much more (I think for the MacBook Pro it was ~$150 more that they wanted for a 8 GB version over the standard 4 GB), thus I think it is really worth doing it yourself.
The next thing I am planning to do is replacing my 250 GB hard disk by an SSD. I have a couple of friend who did this recently, and it will definitely speed up your machine, too. Most notably, the boot will perform within a few seconds instead of the usual ~ 2 minutes, and the computer goes to sleep almost immediately if you close the lid. Also, general writing and reading tasks of your hard drive will increase significantly. Furthermore you won’t have to worry about damaged hard disks anymore if you move your MacBook around or drop it when it is on. However, MacBook hard drives have an in-built security lock mechanism that locks the disk read/write head of the hard disk if there are shocks from the outside – this is where this clicking sound is coming from.
