Raid

[Sk-Kadin]

This is the most general question but where can you use raid, where, and what is the benifit. Here again I know this is general but I just want to know more about raid and what are the different versions used for

It isn't really worth it unless you are Linus and need it for 8k video transfers and mass storage.

Lol but if I do need it for that...

Then WD Red or the equivalent Seagate raid like 10 or 5 i think? The high speed ones would be like raid 10 or 5 NVMe SSDs.

Ok so it is just the faster of a transfer speed from drive to drive

RAID can be used for speed in RAID 0. There is a wikipedia article HERE. If you want high boot speeds, one SSD is usually good but a RAID 0 can improve it by a bit. It isn't recommended because if one drive fails, the entire array fails in RAID 0. For redundancy, 10 and 5 are good if you have a lot of drives.

RAID hasn't really changed in forever.

TBH, I hate the idea of "stacked" RAID though (RAID 10, etc.).  If neither RAID 0 nor RAID 1 are for you, I would recommend looking at RAID 5 or RAID 6.  Why?  Well remember how he said "up to 2 drives" talking about how many you can lose with RAID 10?  That's because it depends which one goes down.  If it's both of the drives on "one side" of the RAID 1 portion, then you're fine, but if it's one on each side, then you lose it all, and so to me, you can only ever think of this as being 1 drive worth of redundancy since you're relying on luck to get you any more than that.  RAID 6 however always can handle 2 - any 2.

Ok that makes sense

 

I’m looking at adding 5 drives to my computer and didn’t know if raid could be useful to me

 

It seems like it could add some performance boost but i don’t know if it is worth going in the trouble to set it up

Frankly, I find RAID of any type to be an unsuitable solution for home users.  The main point of it is to protect you against drive failure, so if one (or more) fails, you can hot swap in a new one live on the go and continue on like nothing happened.  If this ability is important to you, then you should be running RAID, but if it's not, then it's probably more work (and cost) than it's worth.  Why?  Well, any sane person is going to keep a separate proper backup anyway, and if you have that, you can always just recover from there in the event of a drive failure, so having RAID for that purpose really isn't giving you anything, but is costing you more in setup time and $ for more HDDs.

Ok that makes sense
