How does raid actually work?

I have 2 ssd. And I saw somewhere this guy had inhumanly fast speeds. Unheard of but I forgot what they were. What Im wondering is if I got a bunch of shitty small 32 or so gb ssd will it make my write speed faster on my others? Is that how it works?

It would work (assuming that you have the hardware capable of it) but it would not at all be worth it. Eventually you hit a limit of RAID 0 making things faster (generally 2 SSDs is max of it being worth the money) and you will just not get any more of a performnace gain. So to answer your queston, it would but it would not be noticable

Make life rue the day it thought it could give Cave Johnson lemons! Do you know who I am? I’m the man who’s gonna burn your house down! With the lemons! I’m gonna get my engineers to invent a combustible lemon that burns your house down!”

Hey 69ing Rainbow Dash,
 
There are two options for the speeds that you are talking about:
- The user had two or more SSDs configured in RAID0 where the speed is multiplied theoretically by the number of drives in the array and you get very fast transfer rates. The downside is that if any of those drives fails, you would lose all data on the whole array
- The user had a Samsung SSD with RAPID turned on and thus getting extraordinary speeds.
- The user had some other brand SSD with a tool to boost its performance.
 
I wouldn't recommend using RAID0 as a boot drive as it actually increases your cold boot time and involves higher risk of data loss. A single larger SSD is fast enough for most consumer tasks IMHO.
