Raid 5 question

easyrider · 5 Aug 2006 at 16:58

I need 3 hdds?

Is it worth it?

I want to have this raid array as a storage and scratch disk for my mini DV files.

As I understand I get striping raid 0 perfromance with redundancy and parity
Seems ideal for what I need.

Anyone doing it?

Onboard or card - I'm guessing ICH7R tbh, in which case parity is calculated by the CPU, giving only about 15-20MB/s writes whilst good reads of about 140Mb/s. Writes will be very important is creating and editing files on the disk itself - you don't want to run out of buffer whilst recording now...

he he smids

ICH7R on the asus p5wdh so worth it?

Raid 5 is good but expensive for a home user.

Just makesure you have a good backup, even get a cheap tape drive.

I understand I have redunancy?

Why try RAID0+1 or RAID10 smids?

Over raid 5?

I have 3 x 300 GB SATA 16mb cache Maxtors

Windows is on my 150 GB raptor.

I have my Raptor pretty much full with Windows,Games and programs.

So the idea was to have a big space for Edit files ect..as I am editing and rendering.

I will partion the array for my media(mp3 and photos etc..) and have another partition for the video edit files

So ideally I need good write performance too.

You mention Raid 5 does not have particulary good write performance?

If i gvet another 300 GB disk and have four does that mean I only get 600 GB storage running RAID0+1 or RAID10?
