Recommand Raid Controller

I require a raid controller for virtualization, the disk subsystem is important and normally the bottle neck for performance issues with VM's. I am looking at raid-5 or 10. Dont really want to spend more than £150.

OK, if you want decent RAID5 write performance then you'll need to spend at least £200 to get a card with hardware XOR support. RAID10 is easy to implement so only requires an add in card if you don't have onboard RAID support.

There are a few things which might be worth considering though

  • How many VMs are you looking at running? If you're running multiple machines then is it worth considering a drive per machine (or two) to reduce I/O contention?
  • What board are you using in the machine? This will determine what slots are available and hence what card is appropriate - there's no point in using a PCI slot if you need a high bandwidth solution for example
  • Do you need a redundant array? What's your backup plan?

I am looking to build a new machine, open to suggestions on spec. The main requirement is to have decent storage performance, im not too bothered about backup plan as it will be mainly used for dev. Just wondering what types of costs for a raid-5 storage solution. Can you suggest any motherboard + raid controller? I am looking at Intel quad core, 8GB mem, and 1tb on RAID-5. Raid-1 for system drive.
 
Reading reviews on Highpoint RocketRAID 2320 Serial ATA Controller it seems to be a decent product at a reasonable price. I am initially going to run VMWare workstation but in the future im looking to run Windows 2008 virtualization product.
 
If I did purchase the Highpoint RocketRAID 2320, what sort of gains will I see compared to using onboard sata raid? Yeah forking out over £300 is out of my budget.
