WD Velociraptor RAID’s?
I’m looking to build or buy a RAID array for uncompressed HD. The cavat being I’d like to be able to use it both on both my octo Mac Pro (full speed) and Macbook Pro (thru a SATA expresscard, and probably not at full bandwidth because of port multiplation/Silicon Image Sandvine issues).
Anyway, now that the new Velociraptor WD drives are out and n established as the new SATA speed king….has anyone built a RAID out of these drives? Curious how a stripped RAID 0 from 2-4 of these drives would deliver. And using a few more of these in a larger array in a bigger enclosure, then how about a RAID5?
Various inquiries to various RAID 0 enclosure manufacturers reveal that nearly every single one uses the Silicon Graphics RAID controller chipsets (IE Disappearing drives). Those that would answer the question anyway, and those that didnt answer would seem to be a definate YES. So who doesn’t? Anybody? Still waiting for an answer from G-Tech….both to that question (for their port multiplied enclosures) and if their products are available with Velociraptor drives. Lastly I am wondering if there are any companies selling bare RAID5 enclosures….

Sorry, but your Velociraptor concept is a total waste of time and money. They are only 300gb drives that retail at more than three times the price of normal SATA drives. Money is much better spent on a larger enclosure with larger and more cost efficient drives. 10000 RPM simply aren’t needed. Eight 1TB 7200 SATA drives in a Raid-5 configuration will deliver bewteen 500 to 600mb/sec throughput.

Thanks for the input. Forced me to reevaluate. I realize that for size and price per gig, its not cost effective. But using 2 of these drives in a small enclosure striped in Raid0 might provide enough speed and be large enough to do what is otherwise not….IE Capturing raw 1080 from a Sony EX into my MacBookPro for later chromekey work on the desktop. So redundancy and reliability is not so important, as its a cheap(er) field-solution for capture. Though with that my concern is the throughput limit that the Silicon Image raid controller chipset places on port multiplication over eSATA…well that and the drives disappearing.

https://www.addonics.com has all sorts of enclosures that you can build a raid from… But they will warn you that they do not offer the support dedicated raid VAR do… Addonics is just a distributor of the part-n-pieces…
But if your brave go for it… The Silicon chip set you refer to is only one of the chip sets that have the Silicon name.. if I remember Bob Zellins post about three months ago… Find the defective model number and steer clear…
If you get a raid to work from scratch, post your results and recipe… I hope to have the extra money to build an external raid by this fall..

Here’s all you need for your laptop Garrett. Stripe two 500Gb drives together and it will easily handle video from your EX. Many of us, myself included use Firmtek enclosures and controllers. They are among the best roll your own raids on the market.
