Doubts:
2x 1TB Caviar Black @ raid 0 vs. 1x VRaptor (both options at matching prices...which wins?)
Does space a HDD space impact performance? Partition allocation? Logical drives?
Would a 80GB HDD with equal specs outperform it's 1TB twin? (no SCSI or SSD here)
Can 2x 7200 RPM 32 cache @ raid 0 match (or outmatch) a single Vraptor 10000 RPM 16 cache?
What else on this build can be improved?

For setup, I would get VR for primary system drive and apps , 1TB for storage. For video editing in CS4 , separating your video files on the 2nd hard drive significantly improves performance. The primary drive will still hold application data and temp files. If you had a 3rd drive, putting temp data, page file on that would even be better

The transfer speeds depend on the platter density. Usually the higher capacity models have denser platters as well as more platters (not always though).

Is that the ideal setup? Let us say on a CS4 driven scenario. Unlimited drives and any raid config possible.
And is raid 0 the absolute ideal for performance? I've read some things about raid 1+0 vs. raid 0+1.
And what about the strip size? I image for boot drive smaller strip and for CS4 work 128 kb strip?
Any ideas? -
If data loss is ok with you (i.e. not important data), and are diligent with backups, RAID0 is ok. Otherwise there are greater risks of failure than JBOD, and it's more than double for 2x RAID0
RAID0 is only good for increasing throughput. It does nothing for access times unless you short stroke the RAID array (i.e. make it a smaller capacity, so only the most dense part of the platters are used). "Performance" is such a generic term. There are many aspects of performance. performance under what conditions ? Throughput is often useless benchmark except for file transfers. You see review sites using hdtach, hdtune - these are basically useless and only measure transfer speeds. Increasing throughput won't (or very negligibly) load apps faster, it won't encode faster, it won't do anything faster except things like copy & paste files. Low access times are the primary reason why perceptibly everything "feels" faster to the user - this is why most SSD's "feel" so quick.
Ideal stripe size will also vary by what controller is used, and what application. Some might be better with 128, some with 64. You have to do some testing for the best.
If you could afford it, I would use a single decent quality SSD (like x25-m or vertex) for Boot/APPS/page (or even 2 smaller capacity in RAID0), and 2x1TB RAID0 for video files, and 1x1TB for miscellaneous storage. NAND based SSD's encounter degredation with capacity filling as well as HDD, so it's important to keep them "empty" as well as HDD for maximum performance. -
in terms of data reliability (less data loss) would a SSD beat any raid configuration?
If performance were not an issue, what raid configuration (for HDD not SSD) would you recommend? for important backups or server data, etc? -

For non important stuff I would still use the config I suggested above. If you have more important stuff, in addition to backups, you might use a RAID1 array. Performance for different RAID levels like RAID5 or RAID6 with onboard controllers is usually poor. Most of the bundled motherboard controllers can only do RAID0 and RAID1 and maybe 5. e.g. if you want a good controller you need a dedicated PCIe Card like an Areca -
Outstanding input. Can't thank you enough how much the insight is appreciated.

Glad to help (and I feel a bit guilty for contributing to your other thread hijack)
There are 100s of review sites and forums that have benchmarks on tech items like hard drives, cpus etc.. and they may help with your purchase decisions
eg anandtech.com , techreport.com , xbitlabs.com, tomshardware.com , pcper.com etc... -

What else can be done to prevent data loss, aside from avoiding raid, and going SSD?
Well obviously RAID0 is the least secure and worst for data loss. You can have various partial failures with the other RAID levels, and reconstruct the data. -
I never recommend RAID 0 for boot volumes, I only recommend redundant RAID levels like 1, 10, or 5. While backups can help save your data in the event of a failure you are still faced with the dilemma of rebuilding the array (if you wait until you receive another drive to replace the dead one) or re-installing to a single drive in the interim. In the case of the former you might be down for a week waiting on an RMA, so is it worth it? At least if a drive fails in some of the redundant levels you'd be able to run until your new drive comes in and in most cases rebuild the array on the fly with no downtime (assuming you don't lose another drive in that time).
Another factor that most consumers fail to realize is that most onboard RAID controllers are rubbish. Even the ones on some of the expensive workstation boards aren't that trustworthy. Most anyone serious about their array is going to get a good controller which is going to run $300-800. These almost always have a large cache and many have battery backups in case of power loss (which help prevention of array failures when you power your system on again). Some onboard "controllers" also use CPU cycles to supplement their performance for their arrays so while you're increasing HDD performance you're possibly losing some CPU performance.
I'd recommend just keeping those drives separate. Having separate drives is very handy when encoding as you can read the source from one drive and write to a second drive. Even with RAID 0 doing a read/write to the same volume would probably be slower. And you don't really want to clutter up your boot drive with documents. Using the smaller Raptor drive forces you to keep your boot volume a little less cluttered. I always recommend installing your OS and applications to this drive only and remap all of your Documents folders to a second drive. A third drive is even nicer when you're working with video projects as you can dedicate one to being your final storage drive and the other to work in progress. I run 5x 1TB drives separately in my workstation, each with a specific role.
Like I said in the other thread I wouldn't recommend SSD just yet. The cost is too high and without most of the consumer items not supporting TRIM it's not worth the hassle. I have two friends with SSD that stopped using them for anything but a secondary drive to install some games to, not even bothering with installing their OS to them. I'm not going to play with any until I get some in at work to test in the VM environment, certainly none for home.FB-DIMM are the real cause of global warming -
RAID0 for boot is a bad idea, any RAID on a mobo controller is a bad idea. Cost/benefit is just not there until you get into expensive, large arrays with hot spares, OR they are just temp storage with no data loss concerns. Better performance requires a dedicated card and GOD HELP YOU if that card fails.
IMO, the SSD's are not yet ready for prime time.
Just a note on the Raptors. I have 8 drives in regular usage, most 3 to 5 years old. One Raptor dirve, which was the newest of the bunch. Now a couple of these drives are a bit flaky, require extra cooling, occassional maintenance, etc. But only one of them just suffered a complete failure with no recovery possible. Three guesses which one that was?
Higher performance often brings a higher failure rate. Yes, it was fast, but not really that noticeable in most situations.
Also, in building a new system, there is no need to get everything right away, many parts can be added at a later date. As a bonus, almost all will get less expensive over time. -

I would trust any of the 15krpm drives I've used over the years (U160, U320, SAS) to last longer than a 7200rpm SATA or IDE drive. The 10krpm Raptors are used in enterprise environments (in fact our HP workstations use them) and I've not seen any failures with them so far. I've yet to see any of my 5 current Raptors at home fail either. An older 74GB got a bad sector (I think from a brown-out that happened) and it was RMAd before it had a chance to fail but it lasted 3 years prior to that. And since it was only one drive and not hundreds of them I used that all failed I can't assume 100% of their drives fail. There's no good sample set on which to base that assumption.FB-DIMM are the real cause of global warming -
The really high-end drives are a completely different price range. I was speaking more of consumer-grade equipment, where the build quality is often not as high. I have read of higher than average failure rates for the Raptor I series.
My personal Raptor experience was a one-of, but the general statement of hi-performance parts OFTEN having higher failure rates is based on multiple hardware experiences.
Perhaps I should have qualified it more with "consumer-grade hardware, particularly early in the products' life-cycle".
Now the Raptor II series has fewer problem reports from what I have read, however for the extra money and fairly minimal performance improvement I perceived, I would invest the money elsewhere. Video card, CPU, RAM, more HD space, almost anything else.
