SCSI raid 0 Q

[weescott]

I just got a PC built at work for HD video editing, 3D modelling etc...:

2 x 3.4Ghz Xeon's
2 gig ram (in HP XW 8200)
Quadro FX 3450
2 x SCSI Ultra 2 15k totalling 300gig (raid 0) for scratch file / storage.
1 SCSI Ultra 2 15k for OS, prog files.

I'm not up on cluster size etc... and what the performance will be like (apart from silly quick).

Does anyone have any benchmarks they can show, links, PE, advice on set up?

Cheers

I wouldn't bother myself with benchmarks of other systems, I'd run HDTach for myself and then use the online compare function to see what other users get if you are concerned.

For cluster size you need to consider what the average size of the smallest files you will be working with will be, I think 64k/128k stripe sizes are fairly common(and useful) but you may want to check that.

My advice would be to make sure that you have a good backup system implemented, if you are dealing with important work then you simply cannot afford to risk losing data due to one drive falling over in the Raid array. Maybe set up a large secondary hard drive(300gb SATA or similar) to archive the work at the end of every day or something like that so at worst you lose 1 days work

I'll take your advice and make sure the data is backed up on a separate networked drive. Thanks

Hmm, me and a handful of others have already taken up 100gig of space on the network, they are going to love me when I start to back up HD videos.
