Raid

[RunWithTheWind]

What RAID is everyone running? I need to know for my ICT Work because I have to write about hadware for a web server for a company and need to include RAID.

We ues RAID 5 on most of our equipment and 10 on some others.

I was doing some reading on Raid 1 and from what I understand you need two hard drives both the same size and all data is stored on both of the drives so if I was running a web server which had Raid 1 and I was hosting my website on it and one of the drives failed then users could still access my sites files as it is stored on the other drive which is working?

Correct.
You would also need a raid controller or raid software.
Actually you could use more then 2 disk if you wanted.

Take a look at: http://www.acnc.com/04_00.html Its a great site, it explains all types of RAID's and what the advantages and disadvantages are.

So, if I was running two SATA Drives would this http://www.ebuyer.com/product/131967

be the RAID Controller I would need?

It looks like it would work. Just make sure you had a PCIE slot available.

Since it does RAID 0 & 1 then yep it would be fine.
RAID 0 is just adding the disk space (not a good idea, one goes you've lost the lot, only good for adding disk space if you don't need any fault tolerance) and RAID 1 allows mirroring, which is the 2 disks with identical data, so a fault tolerant system allowing recovery from one disk going bad.
