I just would not want to go that rout. I would chose a buch of different raid setups before I went raid 1. That's my opinion. I gues this is more like a Chevy vs Ford type of situation.
I think he already realized the answers but he is just stuck on RAID hardware. That or he is being fed false information.
Most of his "reasons" for wanting RAID are actually reasons he should be checking out something like flexraid.
His point it's faster seems wrong. It's not- it's still limited to the speed of your HDD's and LAN. Which in most practical purposes is about 110MB/sec. Gigabit LAN with a perfect run is theoretically capable of 125MB/sec but no one ever gets that. Usually if your getting 100MB/sec your doing ok. Building or buying a machine that is going faster than 125/MB sec is futile because you will never realize it- your speed limited by your LAN. Only if your installing locally on a local machine would the extra speed ever matter and in that case your not talking about a server anymore. Plus my Flexraid server consistently delivers over 110MB/sec and it's 30TB in size. I'd crap my pant if his used HP could hit either of those marks.
Second, (well actually third because second point was the HP and RAID is going to be slower than he thinks)
I am not sure who gave him his information but restoring a failed drive in flexraid is as simple as clicking "rebuild drive" after installing a replacement HDD. In my case, it's hot swap able and takes 5 seconds and no tools. I can't imagine any RAID box would ever be easier so I am just assuming he doesn't realize what is involved with swapping out a drive in flexraid.
The cost issue I already explained in his other thread here:
itznfb and spectrumbx (Brahim, inventor of flexraid) got into a nice mine is bigger than your's pissin match which somewhat derailed the thread but nonetheless provides amusement.
On the cost issue,
First you need to buy more expensive hard drives that play nice with TLER. You can't use cheap ones because you'll constantly be having issues. Hardware raid requires a drive without TLER issues and without head parking- at minimum your looking at a WD RED which is $30 more on average and quite a bit slower. WD RED is only 5400rpm and generally a very slow HDD so his entire idea of speed gets thrown out the window. Most enterprise RAID certified 7200rpm drives run $200+ so costs becomes a major issue too. And again- you can't go faster than LAN anyways so it really won't matter. It's just money wasted.
