![]() ![]() This is in contrast to the junky 43 to 85 megabytes per second you get now, with all the latency from mechanical spinning hardware. With two SSDs in RAID 0, you will get almost double the read/write speeds of a single SSD - you will have nearly 1000 megabytes per SECOND read and write speed on your laptop. 250 GB SSDs are $100 now so two of the plus a caddy to put the 2nd SSD in the optical drive bay is $230 total. For less than half the money of a replacement logic board your laptop will scream as if it were a brand new retina with PCI express SSD. ![]() Going from dual core to quad core is noticeable, going from fast dual core to slightly faster dual core in the same processor family will barely be noticeable.įor day to day tasks, you can buy two SSDs and put them in RAID 0. While you can go from a 2.5 i5 to a 2.9 i7, this will make no difference in day to day tasks - only long video encodes. You are looking at $500 to $600 to buy a known good board with that CPU. You won't notice the difference in CPU, but you will be spending $450-$600 on it! You should try to leave 1/4 to 1/3 of the drive free for the OS to do its thing. ![]() Lastly consider defrag'ing the drive as over time they do get fragmented. You may want to run disk utility to make sure the permissions and drive are in good shape, then do some system house cleaning deleting the old cache and log files. I can think better things like upgrading your current HD to a SSHD hybrid or even a SSD drive either would be a better investment.īut before you do anything use your system as is it might meet your needs as is! As you can see this series had only two systems a i5 (2.5 GHz) and a i7 (2.9 GHz).įrankly, I think the amount of improvement is not enough to warrant swapping it out. In your case this would be the MacBookPro9,2 Series. ![]() If you jump down to Step 27 you can see the CPU is firmly attached to the logic board (soldered) so swapping it out is just not possible without swapping out the entire logic board.Īs to what boards fit, its best to stay within the model series. First lets work with some facts, here's the IFIXIT guide to replace the systems logic board: MacBook Pro 13" Unibody Mid 2012 Logic Board Replacement. ![]()
