For general Infos i recommend this Article from SamsungīTW, to create a homemade Fusion Drive you need to use the 'Core Storage Volume' Command. of a better Garbage Collection within the SSD Firmware (see this article and this Article). There are Tools to enable TRIM Support, but it could be a not necessary bc. Fact is, Apple has Trim Support enabled only on its own OEM SSDs and disabled it for third party drive. Re 3: There is a hot discussion going on if Trim should be enabled or not and if that is a bad thing.
SAMSUNG SSD FOR MACBOOK PRO MID 2010 UPGRADE
You should search for the Tutorial for your model, the link i posted is probably not for your model. SSD 1TB PCIe NVMe Gen3x4 3D TLC NAND Flash Hard Drive Disk Upgrade for MacBook Pro Retina Late 2013-Mid 2015, MacBook Air Mid 2013-2017, iMac Late 2013-2017, Mac Pro 2013, Mac Mini 2014.

Re 2: The best tutorial for replacing the optical drive with a harddrive (or SSD) can be found at, f.e. of a (probably) better Garbage Collection (see #3), else go for the 840. I can't really prove it, I my self, am a guy that needs hard proof, but this isn't a coincidence. Re 1: hard to say - if you can spare the Money you should go for the 850 bc. Its not the laptop ( MacBook Pro 17' Mid 2010 I5, nVidia 330M ).

SAMSUNG SSD FOR MACBOOK PRO MID 2010 SOFTWARE
I need some advice because, while I know quite a lot about software (I study Computer Science at University), I'm not so good on the hardware side of things. I have already upgraded the HDD from 250 GB to 1 TB and the RAM is 8 GB, upgraded from 4 GB.

You do the math.I have a mid-2010 MacBook Pro, which I want to upgrade with an SSD in the Optical Drive slot and create a Fusion Drive (using the Terminal diskutil command in Recovery Mode) and then re-install OS X Yosemite on the newly created Fusion Drive. Right now I myself use a 4-th SSD Samsung 840 without trim enabled. It's been 3 moths since, and they haven't returned since. After replacing them i hadn't turned on trim anymore. They both came back to me in a month and a half with a fired SSD. I just recently had 2 customers with a macbook that asked me to upgrade to an SSD. Its not the laptop ( MacBook Pro 17" Mid 2010 I5, nVidia 330M ). If it were a motherboard problem, they would have found it. As I was saying, I work in a service, I have tech guys which are very good at what they do. As soon as I turn on trim, with in a month or so, my SSD dies. If you use your MacBook for heavy tasks like gaming, photo/video editing, 3D modeling, etc. Cant really explain it, not an OS X expert. Crucial MX500 is top pick, followed by Samsung 860 EVO, and the third is SanDisk X400. So I deal with a lot of laptops on a daily basis. Im at my 4-th right now ( thx God for warranty ). I fried 3 SSD Samsung 840 ( not the pro version ). The problem with the OS X Trim command it that it kills your SSD.
