Hi Bob,

And thanks for the answers! There are some question marks remaining, though:

[Hi - your post is misleading. There is a G-Tech forum that could answer these questions better, than an AJA forum.]

OK, I'll check that one, too. For the moment, I haven't decided on the brand of the storage - I'm trying to figure out which is the right one for a system that has only two components clear: a Mac Pro and an AJA.

[you don't need a Red Rocket to work with Scarlet, or any other RED camera. Red Alert and Red Rushes are free downloads from, that you can get right now to translate your footage to Apple ProRes422.]

I had the impression that the "native" Red card offers some benefits in working with Red's RAW files instead of exported .mov files. That's not so much of an issue for the time being, anyway - so let's skip it.

[ two G-Tech G-Speed eS Pros will not do sustained 2K, but will work fine for all of your standard def and Hi Def compressed HD stuff]

What G-Tech claims is that "A single G-SPEED eS PRO enclosure with four 7200 RPM, SATA II drives in RAID 0 mode supports multi-stream ProRes 422 HQ playback and a single-stream of uncompressed 10-bit HD. Two units with eight drives in protected mode (RAID 3 or 5) supports two simultaneous streams of uncompressed 10-bit HD or a single 2K DPX sequence." (

What I am trying to get is if this is true in a real-life situation, or is there some "catch" that sends it far away from what is claimed. I have not used any G-Tech product before - and I'm open to any other solutions that would allow me to grade a final, online, uncompressed 10-bit HD master sequence in real time.

[inexpensive drive arrays will average about 200Mb/sec. The more expensive ones (that can do 2K footage) will give you about 600 - 700Mb/sec. These cost around $5000, and come from the better companies that you see advertise on Creative Cow. G-Tech makes "good stuff" and "cheap stuff". The good stuff will do 2K, the cheap stuff will not. Same applies to most manufacturers. ]

So, which models are which?

[RAID 5 is the best option for you. Almost no one is doing RAID 3 these days, and RAID 6 is for larger systems (like 16 drive systems). You can run RAID 6 on less drives, (like an 8 bay) but you decrease your storage and speed too much.]


[- what RAID controller? I saw MaxxDigital, Dulce, JMR or GTech mentioned in other threads, but which one (tested in real-life) could control an internal array, and have the option to add external arrays later on?

- you are buying a package from any of these companies. If you buy the G-Tech G-Speed eS, you will get a Highpoint host controller card with this product. Dulce, JMR, Maxx Digital, Cal Digit, and others sell you SYSTEMS that work - all are excellent companies, all will provide you with professional host controller cards, disk drives, and chassis that will work professionally, and give you the performance for your 2K work, as well as RAID 5 protection. You will not "piece together" a drive system with components from Dulce, Cal Digit, JMR and Maxx Digital to make a cheap working system. ]

OK, so what is the maximum bandwidth I could expect from a "home-made" internal array (an X-brand controller with 4 HDDs)?

[- RAM: are the 6 Gigs that come standard enough, or should we add more?

- for a stand alone FCP system, 6 Gigs is enough. ]

Good news. Thanks! :)
