From my experience using it with video capture from a digital video camera, it isn't. Capturing to a single drive is no problem because the bandwidth required for capture is well below typical drive throughput, (hence where I said a 4200RPM drive is fast enough - if you have problems capturing, the fault generally lies elsewhere, eg. PIO, background processes).
Capturing is one thing, but editing, scrolling through frames etc... I would think
a stripe makes things a bit more comfortable there? And whether a 4200rpm drive is appropriate for capture probably also depends on the source format... how much throughput does HD video require?
I don't think it would change 'game load speed' but what about loading of data during game play? I'm talking about those games that pause every so often to load in the next >200MB resource file.
it would have helped there, since many games seem to have relatively
low CPU usage while loading, indicating that they're disk bound. But my RAMdisk try with Thief3 was disappointing, and a "die/reload/try-again/die/..." cycle in half-life2 where everything should be in disk cache (8 gigs of ram...) it was pretty much the same results, so I don't think a stripe would help much there.
I wonder what
the games are doing during load, if it's neither CPU nor disk I/O bound. Perhaps something to do wrt. uploading textures to the GPU, but that's supposed to be super fast (PCI-e x16 has quite some bandwidth). I really don't know
When I refer to 'home environment' I don't include a business, (which is what your "whole day's work" implies to me), that runs from home - that's no different from a business in a store or a corporation, (except in size), AFAIC - and as such your backup strategy should be more robust.
I know my backup strategy isn't robust enough
When I refer to home environment it is reference to the generic home PC that's used for games, internet, the odd word processing, picture collections, etc. For that, I really don't see any need for RAID. Not even for video editing which I do at home on my general purpose PC.
As long as a solid backup strategy is in place, a mirror wouldn't be necessary for that kind of home use. But a backup strategy certainly is
, lots of people have irreplacable data on their systems now, and don't even think about the possibility of their drive dying... photo albums, anyone?
Yep, no problem with this for business applications, (and those that are just plain paranoid ). But for generic home applications a decent backup setup is more than adequate and a lot less hassle when it comes to restoration in the case of a fault.
Agreed. I'm probably borderline paranoid
. But I've experienced losing 3 years of programming and stuff (a mirror wouldn't have helped me then though, but that opened my eyes), and I've been very close to losing a lot of work due to a drive failure.
Anyway, the RAID MIRROR is crucial for my fileserver, since that's where I store the backups (yeah, I do have manual
backups of a lot of stuff, I still need an automated scheme though
