Re: cloning drive to Raid 5

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

The controller is LSI MegaRaid 8204 PCI-E card and there is no battery
backed cache on it!
(not my choice I like Adaptec one.. )

Checked the settings WRITE cache is disabled - default
If there is no battery backup - this is probably a good idea!

Software - I've tried Drivesnapshot and Ghost. Both work but SLOW...

I have setup an RAID5 using SAS drive (4 x 300GB SAS)

I tried to Clone our SATA based Windows installation 280Gb and I got an
estimate of 5 days !!!

So as a test I cloned the Windows C drive to another SATA - took 15
minutes
did the same for the to the RAID5 and it took 300 minutes.

I know RIAD5 is not exactly a Speed thinng....but

Does that mean my RAID5 is 20 times slower than nonraid SATA ??

What cloning tool are you using?

Is the RAID-5 on a dedicated RAID controller with CACHE RAM or just a
motherboard RAID?

It's possible that your cloning software doesn't support the RAID
controller fully.

Did you let the RAID Array finish building first?

Did you set the RAID Properties to give priority to WRITES?
