Are there data showing that Barracuda is faster than Constellation HDDs (of similar specs) or is it more of an assumption? I understand Constellation HDDs are enterprise class HDDs but that does not imply performance gains or loses. Constellation of course offer better MTBF numbers and usually cost more. Just concerned about speed performance differences if they exists.

It looks like WD Black and RE out perform Seagate Barracuda & Constellation, agree? Is WD that much faster than Seaqate? How do they stay in business? What am i missing? I always liked Seagate more. WD have too failed for me over the years.

Any Seagate fans out there? WD fans?

I am looking for HDD for a RAID0 (video edits and capture) and a RAID 10 or maybe a RAID5 for storing the video I just edited. I would think the RAID0 HDD should be fast and stable, while the HDD for the RAID5 or 10 could use cheaper models. Agree?

Per the reviews, it seems I should chose WD, but . . .

Suggestions please.

Thanks,
William

I've been a fan of the Samsung F3 1tb. For RAID-0 I would avoid 2tb drives and stick to 1 or 1.5tb. It would seem there have been enough issues with the 2tb drives that I personally would avoid them for now. Seagate will be shipping a new batch of HDDs based on a 1tb platter by the end of the year so I would think 2 and 3tb drives based on that would probably be great. As far as going enterprise or not: enterprise drives can still fail. They are usually more sturdy and are designed to run 24/7. If your data is really critical then RAID-0 isn't really what you want. Performance between different modern HDDs isn't that much different in the real-world when you compare the same spindle speed of drives.

I don't. The more drives you have in a RAID, the better they should be. If you don't want to buy RAID ready drives like the Seagate Constellation or the WD RE, then you should definitely consider the Samsung F3.
