Most bit for the buck Raid

[Walter Biscardi]

Have you done a search on this forum? Just about every RAID out there right now gives you an option for RAID 1, which is bare minimal protection. There have been a LOT of discussions about RAIDs and hard drives in general over the past 6 months on this forum.

I hope you don’t intend to edit anything raid 1 as that will not have the speed you need for video. Raid 0 will give you what you need for speed but you should think about adding another drive and going raid 5 to get the redundancy.

that’s completely false. RAID 1 is just fine for editing video depending on the unit you’re using. Not much slower than RAID 0.

Not in my experience. Raid 1 will work for short clips but on long captures say 30 min tapes you will start to see through put issues not all the time but enough to drive you bonkers.

What units are you using? We have two LaCie SATA RAIDs that are both running RAID 1, and we’ve got a set of CalDigit Firewire VR’s that we’re testing, all in RAID 1. We’re cutting HD with the LaCie’s and SD with the Caldigit’s, no problem.

RAID 1 has nothing to do with the problems of your captures. The drives you’re using are not fast enough in RAID 1 to support what you’re doing.

That’s like saying RAID 3 or RAID 5 is too slow for editing video. With the wrong drives, yeah, that would be true, but that’s a product of the array you’re running, not the RAID setting.

OK they have been 7200 rpm Segates SATA 300 and a WD 1tb my book and these are just for low res wmv and P2 offline. We use a SAN for everything else.

So you have Seagates striped together in at least a FW800 RAID (hopefully they’re SATA) and the MyBook is also at least a FW800 RAID? All the MyBooks I’ve seen are FW400 only for the fastest connectivity, you wouldn’t really want a FW400 device to run in RAID 1.

What company offers >2t with raid 1 configuration?

jmf

External SATA for the Seagates and fw 800 on the MyBook Pro II (it was on sale when they closed the CompUSA here).

Here are some samples of read and write tests between raid 0 and raid 1.

I just finished editing P2 DVCProHD 720P 24fps @ 29,97 on a SmartDisk Firelite connected (including power) via FW 400 to my Mac Pro. The project is also on the drive. Not a single solitarty dropped frame. And dissolves were realtime.

I didn’t really expect the little drive to perform like that, but I was very impressed! Given this was just some broll cuts. Wasn’t trying to do any layers or anything.
