Regarding Backup. No Firewire 800 is not the fastest.
What you really want is eSATA. Buy almost any external eSATA RAID enclosure like this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817707156 and put in any SATA disks of your choice for the most cost effective solution. If your computer is not equipped with an eSATA output and you have a spare SATA connection on the motherboard a simple SATA to eSATA bracket like this one. http://www.newegg.com/Product/Product.aspx?Item=N82E16812226006
Do not forget to get an eSATA to eSATA cable.
Do you know how much faster that is in comparison to a Firewire 800. Does it basically blow Firewire 800 out the door?
I found my answer
- USB 1.1 – 15 Mbps
- FireWire (1394a) – 400 Mbps
- USB 2.0 – 480 Mbps
- FireWire 800 (1394b) – 800 Mpbs
- SATA 1.5 – 1.5 Gbps
- SATA 3.0 – 3.0 Gbps
Those are maximum bandwidths specified by the various technologies. Actual transfer rates never get that fast in the real world.
If this were me, I'd put the media on a RAID 3 drive, which offers both speed and data security while editing. Once the project was finished, I'd archive to either Blu-ray data disks or a hard drive I could put on a shelf.
Would you still get a eSATA over the firewire 800?
I only use internal drives. Especially for RAID 3, I think you'd need to.
I am looking for external solutions for a few reason.
Were I in the unfortunate position of having to use an external drive, then yes eSATA is the best way to go. I'm just not sure if you can get one in a RAID 3 config, though. You'd have to shop around. (And if you do find one, it probably won't be cheap.)
A crude rule of thumb on effective average transfer rates:
1. USB2.0: between 20-25 Mbps
2. Firewire 400: between 30-35 Mbps
3. Firewire 800: between 50-60 Mbps
4. eSATA: between 80-110 Mbps
eSATA is the only sensible option for external storage.
Raiding USB or firewire is a complete waste of effort and not worth the extra investment if you find an external enclosure with raid capabilities. The raid capabilities in those enclosures are absolutely worthless, CPU hogs, draining resources and have no hardware support. Stay far away from them.
What makes sense is raiding eSATA drives if you have a good controller.
External drives not of the type eSATA are mainly for backup, not for editing.
