  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

RED RAM vs. RED DRIVE... unexpected results

hey brook, what happened to your test?? (i know you have been a very busy beaver. ;) )

Heheh, sorry about that. My last job was without internet access, so I wasn't able to post anything. The results live on my work machine, so I won't have access to them until my next prep. I've got something going on this week, but I should be all over it by Friday.
 
RED-RAM problems

RED-RAM problems

has anyone experienced mounting problems with red-ram to macbook pro. We never manage to connect via firewire 800, plus it takes couple of attemps to mount via USB.
The other problem is R3d data manager always crashes while transfering from red-ram . Any answers?

Yes, I've seen that too. Once, a few months ago, the Red RAM didn't mount at all on any computer, with any connection( USB2, FW400, FW800), with any cable. I spent more than one hour trying to figure it out. It was still mounting fine on the camera.

I finally figured it out : instead of pluging the power cord first, and ther the FW or USB cable, I did plug the USB or FW cable first, and after a few seconds, the power cord. Since then, it has always worked fine this way, no more issues. It still takes 20-30 seconds to mount, but I guess that's how it is.

Also, try to unmount it properly from the camera before unplugging the cable (even if you shut the camera down).
 
Just want to had my stone on this thread.
I had been testing SSD drive speed from an early SSD MacBook Pro. The drive was actually slower than the usual 5400 HD on older laptops.
I have been told that SSDs on MacBook for european market were the bad ones at this time (I don't remember the brand).
I have since tested other brand's SSD that really make a difference.

Maybe the SSDs on RED RAM are the bad ones.
 
Many OEM SSDs that pre-installed in laptops, especially older ones, are quite slow. It is generally very highly recommended to read up on SSDs and buy one that fits your needs, since if you leave it up to computer manufacturers, they will usually give you one that is less than half as fast and more than twice as expensive as the ones you can buy separately and install yourself or have installed.

I have also encountered significant bottlenecks in esata cards that use expresscard and cardbus interfaces.

I would expect that RED tested their SSDs, and it is certainly hard to imagine they released a product that is slower than RED-DRIVE at such a huge markup. Although slower or not, SSDs do still provide the benefit that you wont drop frames when shooting in environments that vibrate the camera.

I would love to be able to hook up a newer SSD to RED as 250MBps backups would save a lot of time. And SSDs sure seem like magic for random disk transactions... Just installed an X-25M in my computer and now every application/file seems to open in <3sec...
 
I would hope RED is using the best SSDs, especially for the money they are asking for one 128gig drive. OCZ Vertex 3 Sandforce drives have read/write speeds of 450 mb/sec, blazing fast.

My next question would be, how long is the life cycle of one of those proprietary RED SSD drives, at $1500 a drive, gets real expensive.

They are. I haven't seen a benchmark on the vertex drive that shows a perfect sustained write speed of anywhere near 450. More like an average of 250. But remember if it drops to, say, 100mb/s for a portion of a second, you have now dropped frames.

This is actually an interesting question...I'm not sure.
 
Vertex 3 drives are writing/reading at a sustained 400 mb + SATA III bandwidth. I have old Vertex 2 drives that read/write at 250 mb/sec sustained.

Just to clarify, this is an old 2009 thread (the last post was a year ago) where Brook was benching the now discontinued RED RAM.

This is not a discussion regarding the new SSD media used on EPIC, also available on Red One with the SSD module upgrade.

Hmm...every benchmark I've seen (Tom's Hardware, etc.) and my own experience and experience of anyone I've talked to has shown a practical single-disk maximum sustained write at about 250 mb/s +/- 10mb/s for those drives.

I'd be very interested to know how you are achieving nearly double that...speed is definitely something we could all use more of. How are you verifying that speed?
