Hi, I'm setting up a mac mini home server. I use all macs (just about) and after trying HP's Windows Home Server EX495 which said it supported mac, and sort of did, but then was dropped by MS, I decided a Mini with some attached storage is the way to go over an NAS, and I'd prefer to be able to mix drive sizes. I've been looking at Drobo, which appears slow, proprietary, and expensive, but otherwise exactly what I want since you can mix drives and it directly attaches. I've also looked at Synology, but everything's a NAS, and I'm just over that, but their Hybrid Raid looks interesting, just not available in a DAS. I'm considering getting a JBOD setup, or perhaps doing a RAID 5 on some stuff and JBOD on other stuff, but then drive size changing is an issue. Is there some kind of mac software out there that can connect to a 5 bay external hard drive enclosure (I haven't picked on yet, probably USB3, maybe this: http://www.amazon.com/Mobius-trade-5-Bay-FireWire-Enclosure/dp/B00CH94GMK/ref=cm_cr_pr_product_top?ie=UTF8&colid=38AFOKNT43ZH5&coliid=I1VI8X89C8CBPM ), that can turn it into basically a HybridRAID or BeyondRAID setup, but the mac mini controls the software instead of a Drobo or a Synology? Does that exist? Or is it a lack of hardware problem? Like the Drobo and sinology work with a hardware / software solution?
