I've done a RAID 0 with a 5400 rpm and 7200 rpm HDD and it still basically doubled my speeds.

i thought raid would work by making exact copies of the drives

That depends on the kind of RAID youre setting up
RAID 0 just stripes your data across multiple disks. If one fails, all fails IIRC
RAID 1 is the first RAID level that mirrors data from one hard disk to another, so that data is intact if one drive fails.
RAID 2 is more rare to see but is similar to RAID 1
Most RAID levels beyond that have some sort of error correction / parity feature alongside disk mirroring, RAID 0 just writes data onto multiple disks, so that each disk has different data that when combined creates an output

while that would create faster write times, wouldn't it also create slower read times?

From what Ive learned, using RAID 0 is designed to have speed as an advantage for both writing and reading, but then again Im not too familiar with RAID nor Hard Drives so I cant be 100% certain

nope, read times increase too
it's kinda like this:
drive 1: byte 1 byte 4 byte 7
drive 2: byte 2 byte 5 byte 8
drive 3: byte 3 byte 6 byte 9
so if you wanted to read bytes 1 through 3, you can send 3 nearly simultaneous requests to read/write data instead of waiting for each drive to complete the operation first.

Most raid levels besides the basic ones are falling out of favor for software based solutions. Software based arrays allow for so much more and are usually cheaper and much easier than a hardware based solution. Like unraid, it allows you to expand you're array with mismatched size drives and if you chose to use a parity drive it just has to be the largest drive.

while that would create faster write times, wouldn't it also create slower read times?

I'm pretty sure it's faster because it splits across pretty close to evenly across 2 drives allowing each drive to split the load of finding things. Though the gains in speed aren't really that great except for some tasks, and even then the risk of having one drive dying and losing everything on both drives is still pretty bad.

thanks bois i get it now

im pretty sure setting up raid doesn't make your disks spin faster. the reason it works at double speeds (if i recall correctly) is that one half of the data is stored in a harddrive, while the other half is stored on another harddrive.

also, if you have a 1tb harddrive, and raid 0 that with 120 gb ssd, i think you get the storage of the ssd, and the speed of the harddrive, which i think is kinda similar in its case

I see. But what if I take the 1Tb at 5400 and combine it with my 1Tb of 7200?
I will get 2Tb's of space apperently since raid gives 2x size of smallest drive. But what about the speed?

Would it make booting faster or starting programs/loading games? But what do they mean with read speed? Not that my current boot time is bad.

Edit: So basicly what I understand.
Write speed splits in half but read speed gets doubled?

Double peformance?
But doesnt that double the time it needs to "read" since well...
You need to read from 2 drives?

Whatever. Ill just buy an ssd.
Say a 60gig one for my OS alone.

i recommend 120 in case you want to put a few slow loading games on it

[ßlöükfáce]

my data is cloning to my ssd

[ßlöükfáce]

it's installed now, and it's still doing the same take-up-all-the-disc stuff as before
