  • 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 :)

SATA out on REDDRIVE

I just went through the FAQ and started to think about my ordered REDDRIVEs the moment I realized that there is apparently no way to get data out via SATA, since the connector is a proprietary part with the REDONE and the REDDRIVE offers FW400/800 instead as outs.
Will there be a way to have an adaptor for the REDDRIVE SATA connector?

It would be far more efficient - when transferring, editing and backing up data - to have a REDDRIVE connected to a SATA Express card or a preconfigured workstation RAID, instead of using FW400/800.

Could this be an option, or are there any obstacles by soft-/hardware design in the way to have this?

Best regards
Boris
 
not sure that's correct -

I know the connection to the camera is proprietary - but I thought there was FW400/800 AND SATA connections on the other side of the drive for offload - now I can't remember ...

Stuart?
 
Hope this helps,

The RED DRIVE and RED RAM digital magazines both have a mini-phono jack connector for external 12V D.C power, so in the case of an e-SATA hook up to your computer you would only need to create a LEMO to e-SATA cable.

At this point in time though, the speed of available hard disks or flash drives is still lower than that of FireWire 800, so there is no apparent advantage to this idea.

Actually I have a feeling USB2.0 might have been removed, not too sure. The ones I listed are infact on red.com but I have a feeling there have been changes since then and simply not updated.

eSata should be 2400Mbit/s (300MB's), firewire 786Mbit/s (98.25MB/s) and USB 2.0 480Mbit/s (60MB/s) - These are not confirmed by Red, just what you should expect from each delivery format. The speed of the hdd in the redrive will probably be slower than esata though.
 
Unfortunatel I am not aware of changes to the USB2 and quite frankly that wouldn't be too intelligent to remove that one as there are PCs out there completely unaware of IEEE1394.
I am also interested in the pin-out of the Lemo-cable. I assume it might be a few percent faster, but in the end shouldn't make a remarkable difference. The SATA interface speeds in general are of no real interest, because as you mention already Paul

its exactly like that: No 2-disc drive combo out there currently touches the headroom of SATA2 speeds. FW is 100MB/sec. and thats probably the maximum of what the little raid is able to deliver (as of current laptop drives, disregarding the performance of the raid DSP inside, which might limit the throughput anyway and wouldn't be too unusal for this special/small appliance).
I wonder if the RED-RAM stripe set could be faster than FW800s 100MB/sec, making the use of an Lemo to SATA adapter very interesting again. But I seriously doubt the controller inside goes beyond that.
If RED uses the same DSP than LaCie in its Little Big Drive, I'd assume it maxes out at 80-90 MB/sec.
Heres a test for the interested at Barefeats.
 
RED DRIVEs have USB2.0, FW400, FW800 and DC power connectors. The DC power is there in case the drive is being connected to a system that doesn't supply bus power over the USB or FW interfaces -- many PC notebooks do not, they only have a 4pin (not-powered) firewire port.

Additionally, there is a proprietary LEMO connector that carries eSATA and power on the same cord. To connect to a system via eSATA, one would have to create a custom LEMO to SATA cable with the proper pin-out. Not sure if RED is going to make a wiring diagram available or if they will even provide such a cable. I'm sure that someone will do it.

As for drive speed, both USB2 and FW400 are plenty fast enough for the current model RED DRIVE. There will be no speed gains by going to eSATA. The RED RAM is a bit faster though -- I think, or at least faster transfer times have been mentioned as a benefit. But we're not sure how fast.. I highly doubt that a current model RED RAM will be able to saturate a SATA connection or even strain a 100MB/s FW800 interface.
 
Jeff for those of us who are pretty computer ignorant does what you say above mean that firewire 800 will download the mag. in about 1/3 of real time? (27MB second recording rate 100 MB second firewire 800 out to portable raid)
 
I do things the easy way. Copying from a FW800 striped RAID [it's old and slow... but so are 2.5" drives] to my Quad G5's internal drive took 7:00 for 20GB. That's 112 minutes total, so just under 2 hours.

That doesn't address any of the other RED DRIVE specifics, though... formatting, file structure, etc. We really just don't know.
 
If you just wanted a cheap windows dub station, is it as simple as adding a 2xFW800 Express card adapter, REDDRIVE in one, out to backup FW Drive or FW Raid? Or is there a speed hit somewhere which makes this a waste of time?

Or does the whole Win Xp S2 make FW800 a no go on Win laptops? (Vista?)

Any external hardware RAID0 configured drive like the 500GB LaCie can take a higher throughput than FW800 delivers, I am using them for this reason,and the REDRIVE is a RAID0.

Anyway if the cable adapter option is possile that'll be fine.

I'm pretty sure FW800 works ok on WinXP, so I too am hoping this ExpressCard style dubbing will be a viable option for laptops, as it's what I plan to use on set to create quick backups for the client.

I am working mobile with a Sony Vaio AR11S (200GB internal RAID0), and it takes my SATA2 drives via Express Card, works flawlessly and fast with XP Pro SP2 (there is definitley no use for Vista in pro domains), FW400 and 800 are supported by XP, I use a LaCie adaptor card for this.

What I am up to with the SATA2 option for REDDRIVEs is using them for this setup as well as for a workstation, where I use a SATA2 patchbay to link any external drive directly into an 4TB RAID0 configuration.
