I'm upgrading a system and I was wondering what would have best performance for HDV:

a) 2 Velociraptor 300GB 10K rmp

b) 3 Seagate 250GB 7200 rpm

I'd appreciate any comment, thanks in advance.

I am no HDD expert. but with the cost of HDDs I would say pickup 2-3 1 to 1.5GB drives and RAID them 0 or 5. 7200RPM is plenty fast for HDV or standard compressed HD video. Look for a good cache amount; 16 or 32MB.

Maybe someone can explain why you should buy a 10000RPM drive.

HDV ingested via Firewire? or uncompressed HDV?

Big difference.
HDV via firewire is no bigger than DV in bandwidth requirements. single drive is fine and 10k is not needed
uncompressed requires a minimum of 2 drives in raid 0.
better off with 2 1TB 32meg seagates/WD's in raid 0.
bear in mind with ANY drive once you get past 60-65% full your speed is drastically reduced.
250G and 300G is way to small.

Thanks for the replies

Well, problem is I'm on budget, and that's zero! hahaha... SAD

This computer is from work, so I had to work with the old disks. The only upgrade I did was the Win7 installation, and BTW I like it lot more than Vista, even more then XP 64.

This was the final setup:

1st Raptor: OS
2nd Raptor: Mpg2 export, AE/AI/PS files storage
RAID0 (seagate 7200 rpm 250 GB x3): video storage
External single 1TB: misc. storage

The raid is working fine with SD Uncompressed, MXF and Canopus HQ (1440 x 1080 files), yet I still need some testing with R3D files.

I will not get any budget until march, so hopefully I'll get a whole new system by then (as this system is almost 3 years old) or at least larger drives... beaurocracy sucks!

Just one more question, have any of you tried exFAT for video drives???

Thanks again.
