I had a RAID set up for my PC over 2x 500GB disks. 

A while ago one failed and I installed windows 7 back onto just one disk.

I'm going to do my RAID again - does my new second disk need to be exactly the same as the other?


what matters here?

It very much depends on the setup, but typically speaking, no. Storage and access speeds will however be determined by the smallest, slowest HDD.

Thanks heaps.

Questions

If I had a 500GB and a 1T HDD and did a RAID. Type 0 my storage would be 500GB only.

How do I see the speed of my existing HDD?

Pull it out and have a look or check for the model number in device manager and then use Google. Just be a bit careful, if it was a motherboard hardware RAID and you have only installed to one disk in JBOD (no raid) it will probably wipe both drives before building the RAID.

I'd also ask what you're trying to achieve.

If you want to protect against downtime due to disk failure, then RAID is an OK option. Although not great if you're not familiar with it IMO.

If you're looking to protect data, RAID is a poor choice, you need backups.

100% agree with this. +1 just didn't do it justice.
