I bought my Macbook Pro in February or March of 2006 and it's still running strong. The hard drive, however, is full and I'd like to get a new, larger, faster one. I'm aware that I need a SATA drive and that it's form factor should be 2.5". I'm also aware that the max transfer rate for my drive is 1.5 Gb/s, can I use one that is 3.0 Gb/s? I think the current drive is 4200 or 5400 RPM, can I use one that is 7200RPM (this computer is mostly used while on AC power)? What about maximum capacity? Are there any limitations due to BIOS or the motherboard? Here is the drive I'm looking at, please let me know if this will work or if you have a similar, better solution. Here are some of the specs from my MBP: Model Name: MacBook Pro Model Identifier: MacBookPro1,1 Processor Name: Intel Core Duo Processor Speed: 2 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 2 MB Memory: 2 GB Bus Speed: 667 MHz Boot ROM Version: MBP11.0055.B08 SMC Version (system): 1.2f10 TOSHIBA MK1032GSX: Capacity: 100.03 GB (100,030,242,816 bytes) Model: TOSHIBA MK1032GSX Revision: AS024B Native Command Queuing: Yes Queue Depth: 32 Please let me know if you think I'm missing anything - I'm looking for at least a couple of different peoples' opinions, or if you have a link that points to replacement HD requirements that would also be very helpful. Thanks a lot!
