The Final Gear of My MBP 2008 Late - 4Gb Ram (2009) - OWC 120Gb SSD (2011) - Data Doubler for optical drive replacement (2011) - 250Gb 2nd HD for optical drive replacement (2011)
Max upgraded, no more can be added except upgrade to 8Gb ram and increase the HD size.
Yup, much faster than HDD BUt the web list the read and write speed can be over 200Mb/s But just test by Disk Speed Test Writing speed only can have about 120Mb/s and reading speed about 200Mb/s Is it normal? SIcne my one is MBP 2008 late, only can have SATA2
