I've got a Macbook Pro 15" 2,4GHz i5, medio 2010. I would like to upgrade to a solid state disk. But will I benefit from a disk with read/write speeds of 500 mb/s? Or what is the max speed that is supported by my SATA controller?

Thank you in advance

You can find the speed of your SATA controller with the System Information application, by clicking system report > hardware > Serial ATA. Which in my case (a 15" 2.53GHz 2010 MBP) shows the following:

Intel 5 Series Chipset:

  Vendor:                   Intel
  Product:                  5 Series Chipset
  Link Speed:               3 Gigabit
  Negotiated Link Speed:    3 Gigabit
  Description:              AHCI Version 1.30 Supported

3 Gigabit means the maximum uncoded transfer rate is 2.4 Gbit/s or about 300MB/s (286MiB/s).

In conclusion: a 500MB/s disk is probably overkill.

Thanks a lot for this info. By my computer the Link speed is 3 Gigabit, but the negotiated link speed is 1,5 Gigabit. So, which number does affects my transfer rate? Sorry I'm quite a noob. –  user31031 Sep 30 '12 at 19:57
I believe that has to do with the disk currently in your Macbook. When you change the disk it should show the negotiated link speed as 3 Gigabit. –  Silex Sep 30 '12 at 20:48
