Bob and David give quite a bit of their time helping people for free, including me. The resources are all here if you want to build your own NAS, but in a mixed pc/mac environment you’re going to encounter problems on top of the usual problems found in a pc only or mac only environment. That’s where their markup comes in. There has to be some profit over cost of materials if you expect people to happily answer all your questions (and there will be a lot of them), otherwise how will they pay their own bills?
There are a hundred different ways to do what you want to do. Inevitably if your business is growing you’ll need to bite the bullet on something. For two users an 8 drive enclosure (or 16 even) would be preferred – there are many vendors that sell those. The drives for this should be Hitachi ultrastars or other enterprise/server class drives. I used to get by with Deskstars, but now I realize that Ultrastars are worth the added expense. You want at minimum RAID5 for protection of your material. Shoving drives in a chassis will be catastrophic if one dies in RAID 0. You want the Small Tree PEG6 (that’s what I call it, it’s actually PE2G or something like that) so that ethernet is regulated accurately to all the receiving systems. You want a good computer to run the server, it cannot run off a computer you are editing with. The computer will need good RAM in it, at least 4 Gigs per user (although I’m starting to think 8 is even better). You will need a RAID card, either the Areca 1882x or the ATTO R680. Some of these solutions offered by the different vendors do not need a server computer, which is possibly why their prices are more expensive than you expect. Also personally, I use NAS instead of SAN.
Long story short, congratulations on your business growth. Enhancing your shared storage is an evolutionary process for a growing video business. As you needs grow though, the costs will grow as well. I will tell you this as the exact same thing happened to me 2 years ago. Get the bigger storage now and do it right the first time. I screwed around for 2 years before I learned this lesson. I don’t sell storage and am not recommending a specific company so perhaps my advice will be well taken.
Good luck!
