Imagine you have three 1TB drives. With normal usage, you have 3TB of space, but if one drive dies, you lose the data on that drive (unless you have a backup).
Now imagine that when you save a file, you write 1/3 of the data to each drive in parallel at the same time. Your write speed becomes 3x faster, but if you lose one drive, you lose 1/3 of every file, so even the surviving drives become basically unreadable. This is RAID0. Max speed, zero redundancy.
Now imagine you want maximum safety instead, so you write the whole file to all three drives. You can lose two of the drives and still have all your data. But your effective storage space is only 1TB, and your write speed is the same as a single drive. This is RAID1.
You can do fancier in-between arrangements that are smarter than RAID1 and give you more space and speed while letting one or two drives die safely (RAID5 or 6, respectively). For further reading:

To make your computer use RAID, you can either set it up in software, or buy a hardware multidrive bay that handles it (like this Orico one).
You still want some backups stored separately in case the machine is struck by powerout/disaster/virus/theft/etc, but otherwise having a RAID means the server can survive one drive dying, and keep on serving users without interruption while you replace the dead drive.
I decided on a Terramaster enclosure WITHOUT hardware RAID and will run software RAID off a mini-computer, together they will act like a NAS. The negative to software RAID is that it is MUCH slower. To offset that somewhat, I'll be using a 1 TB NVMe SSD as a read/write cache and a 10 Gbps USB connection. The positive is that the drives will remain accessible even if the software RAID fails as long as I use the same software. So that's the trade-off, not perfect but it's what I decided upon.

Yes. Pick up a cheap mini pc for $125 and plug this in. Set up Samba share and away you go. That assumes you already have hdds to fill it. I am considering ditching my server and doing just that. That said I have a 224+ already so I could use this for other storage for security cameras and the like.
You put one or more hard drives inside of this thing (up to 4). Then plug it into a computer using a USB cable. Your computer then sees the hard drives. Or your computer sees it as one large combined drive.

With that said, I'm still rocking my 8+ year old ASUStor with x4 Hitachi platter drives. Prefer them for archival reliability over an SSD in this application.

5gbps is 625MB/s, which would be plenty sufficient unless you're hitting all the drives at once or they're SSD's, at which point if you're going for parity or high performance, you need to start looking at actual NAS's or enclosures that can handle a NAS setup.
