Is it possible/worth to RAID with my disks?

ance242 · Jan 28, 2014

Hello everyone,

I currently have 1 SSD 120gb, 1 HDD 750gb and 1 HDD250gb. I was thinking what's worth doing: adding one more SSD/HDD and set them up in RAID, or just replace them with bigger capacity drives? Please explain as simple as possible

Thanks in advance!!

RAID only really works when all drives are the same size.

Also, RAIDing between different types of drive (e.g. SSD/HDD) generally hinders speeds, rather than increasing them.

What's your motivation for changing stuff? Need more space? If so, just get a 1TB+ drive to replace the 250GB.

For normal desktop use, the only two words you need to know for RAID are: "Don't bother"

1. With RAID 0 (striped) or RAID 1 (mirrored), the drives should be identical sizes. Otherwise, you are throwing away much of the capacity of the larger drive.
2. RAID 0 with SSDs, you gain little if any speed benefit. And increase complexity and fail potential.
3. A larger SSD is faster than two smaller in a RAID 0 array.

What are you hoping to gain from this? Which RAID level were you thinking of, and why?

Well actually i want some space and speed. Windows are installed on my SSD but with some more things i have there it leaves no more space and i have to deal with my other drives which are slow and a pain to search through them to find things i had put long time ago. What I actually want is something between size and speed for gaming storing things , fast operations and maybe less drives like D, E so it can be easier to store stuff in one drive ! I dont have much knoweledge about RAID but maybe something like 10 for speed and safety.. Thanks!

I'd set up things like this:
120GB SSD - OS and applications
New 2 or 3TB HDD - all your other stuff
Existing 750GB HDD - backups of critical data. Automated backup nightly.

Thats a decent solution ! Thanks a lot both of you! Can you please suggest a programm for automated backup?

SyncBack Free
Point it at source and target folders, give it a schedule. Done.

For instance, I have my Documents libraries backed up to two locations every night. 2AM saves to another internal drive, and 3AM to another PC on the network.

Yup, Syncback is bloody awesome.
