Hi, I will be moving from a '08 Alu Macbook to a '12 MBP. Just for background, the '08 Alu Macbook doesn't have a SD card slot. -I will be purchasing a USB 3 stick for various reasons. With this in mind, I wasn't sure what I could use the SD card slot for, but since I've never had the opportunity to have one on my computer, I could just be missing something. So I ask, with the USB stick in mind, is there anything I can get out of using a SDXC card? -Awhile back, when I first started investigating SSDs, it was deemed almost universally important to have either TRIM enabled or a form of garbage collection on your SSD. I plan on purchasing a Samsung 830 series SSD, do either of these things mean anything to me anymore? Do I have to do something special on my own to address this? Thanks in advance to anyone who can assist me or contribute to this thread.
