Hi, everyone. I have been reading and reading these forums, but all it is doing is causing my head to spin. Between different opinions, uses, and flat-out arguments, I can't keep up. So I apologize in advance for staring a new thread, but here's why: I currently use a Mac Mini that I tricked out (as much as they can be tricked out) with two Samsung 850 EVO SSDs, maxed out memory, and two external USB 3.0 back up drives. The thing is great, and really serves every need I have... except for editing video and photos of my kids. Can't do anything about built-in, crappy video, and it takes FOREVER to do anything at all. So I just bought a Mac Pro 5,1 (2010 2.4 8-core) in like-new shape for not a lot of money. Yes, it's older, but -- from what I see -- it can still crush everything I would need it for: Internet, Office, family photos and videos (lots of them), and the occasional Civilization game. I do not use Windows (except at work), so I don't need dual-boot drives, etc. After being spoiled by the Mini's SATA III SSDs, however, I don't want to move backwards in the speed department. When I researched SSDs in the Mac Pros, I saw there were two options: Installing a SATA III SSD (running at SATA II speed) in one of the regular bays, or installing a PCIe SSD (Predator or Samsung 941) in the PCIe slot. After that, it's a blur to me. People talking about boot drives, TRIM (I honestly don't know what that is, but also read that SSDs should not be trimmed), speed of the drives not meeting the speed of the system anyhow, scratch drives (don't know what that is either), etc., etc., etc. Guys, here is what I have now and want to move to the Mac Pro: 1. A boot drive similar in speed to what I have now that has the MacOS on it and ALL of my applications 2. A second drive that has all my music, photos, videos, and documents 3. A third drive to back up both drives regularly. That's it. Could someone please tell me the best drive solution and briefly explain why? Are there any other upgrades you would recommend given my little use? Seriously, if there was a way to upgrade my Mini's GPU, I would do it and be a happy man. But there isn't, and I am sick of watching the spinning beach ball every time I try editing a simple video on IMOVIE of all things, or when I play the random game of Civilization. Sorry again for starting a new thread and for the length of my post. I just thought it would be better to explain my exact situation up front. Thank you in advance.
