I was looking to suggest upgrade our current DIT system after on our most recent shoots the transfers have kept us behind on set. After some web searches I wasn't able to find answer to the technical questions I have, so I figured if anyone knew, it would be DIT RedUsers.
Current Setup (in short);
17" 2011 Macbook Pro i7
Sonnet Pro eSATA Expresscard/34
FW800 Red Station
My questions are the following;
- In using the eSATA card, does that provide the maximum speed for Expresscard/34 of 2.5Gb/s rate to each port (i.e. to each drive?) or does the card split the transfer rate if two devices are connected thus leaving me at 1.25Gb/s per connected drive when two are attached?
- With USB 3.0 on the new Macbook Pro's, does each USB 3.0 port have 5Gb/s when multiple drives are connected? or is 5Gb/s split between each port when multiple drives are connected?
- If we kept our current setup and upgraded the Macbook Pro, would I see a noticeable increase if I were to get an eSATA breakout box (VIA thunderbolt or USB 3.0) and just used all eSATA?
- Speaking of breakout boxes, the Belkin Thunderbolt Breakout box (http://www.belkin.com/pressRoom/rele...ck_060512.html). Is my theory sound that all connected devices share that 10Mb/s connection and thus if i used 2 USB 3.0 drives they both would get 5Gb/s each? Or since its only a single device thats connected VIA thunderbolt that it would be like daisy chaining FW800 and the rate would suffer because of multiple reading and writing going on in the same pipe?
- If I were to suggest getting a Thunderbolt RAID, it makes no sense to get platter based drives as they are limited to ~300Mb/s on SATA and since Thunderbolt is 10gb/s a 4 bay RAID would be split to 2.5Gb/s because the drives are all sharing the same 10Gb/s port, correct?
- Price and Availability in mind, if we upgraded our Macbook Pro and bought all USB 3.0 platter drives, would we see a noticeable increase over eSATA with our current solution? Or does the platter drives speed make that upgrade moot?
- With my current setup, is it better to have the Red Station hooked up to one of the eSATA ports and have one of the drives on the FW800?
Thank you thank you thank you to any and all who can give their $.02!
