HDD Storage System

Hi folks, I've recently had an external HDD die on me losing a lot of info. I'm now looking to obtain an external or internal system that will store our data & other stuff which automatically backs itself up but also has the facility that if a drive dies another drive has mirrored the data & then I can just swap over a drive.
What's out there in terms of kit available, so I thought I'd ask the experts!!

I'll join in on this one; I'm thinking of about network storage, needing about 500G maximum, so a 1TB RAID would be fine.

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.
Camera settings documents are held by Daniel Browning and at the EBU
My book, 'Circles of Confusion' is available here.
Also EBU Tech.3335 tells how to test cameras, and R.118 tells how to use the results.

i recently bought a drobo. It takes 4 sata drives and can cope with one drive completely failing without losing data. Then you just replace that drive and it sorts itself out again.

They are expensive but require no maintenence. With four 1 gig drives I get three gig of storage and the other 1 is used for redundancy.

I use software RAID

This doesn't really answer your question, but let me share what I do. I buy four SATA drives, pop them in a AMS VENUS T4S ($180), and plug them into e-SATA on the computer. I use software RAID-5 on Windows XP and enjoy 2,640 mbps reads, but writes are pretty slow at 240 mbps. Up to nine terabytes so far. When a drive dies or Windows crashes, it has to verify the array, which slows the array down for several hours as it scans 3 TB. Not automatic, so I wouldn't recommend it.

I use an external eSATA Thecus box from Worldspan, backing up as a scheduled task using Acronis on the first shutdown each day. My box has two drives, but they are available to take more. The box also has a USB2 port, but this is nowhere near as fast as eSATA. The box has internal hardware RAID, which I have set as RAID 1. This makes the array independent of the system Windows, so it is not affected by system problems.

I also love the idea of thr Drobo, but do ensure that you get the new, more expensive Firewire one, rather than the old USB2 one.

Chaps, thanks for the ideas I like the Drobo & the Thecsus. I'm looking into these & will advise which one I choose to meet our requirements
Thanks

i bought the firewire one from scan. was thinking of getting it from states but shipping and tax made it the same price.

Due to lots of other issues I didn't get round to sorting out a HDD, however now time available I'm abaout to buy what I thought I needed until..........
I have been advised to look at the Buffalo Terastation, but to cover me for present SD work & future HD work I would like to know from you guys as to whether this has got a suitable data rate to enable transferring the footage to & from the unit?

Guys, had my network chap round last week to discuss way forward with storage & back up. I think I have settled for the Buffalo Terastation Pro as it can work on a Gigabit Ethernet network, cover more than 1 computer & has inbuilt back up facility. I'm thinking of having this set up as the main HDD as it has 4 drives in there, so the risk of 1 HDD failing which has the data on it is alleviated as the other drives will be accessed to use it!
One question I have is what is the data rate I need to have to enable video footage to be transferred to & from it real time for SD & HD?
I hope I have got this question correct so that you guys understand what I'm asking!!

I think you might struggle with data rates across a gigabit network for HD video, if you want to edit and play video. Fibre optic SAN is normally used.

Hi
Its possible to do compressed HD over a seperate dedicated gigabit network, but there's a lot of specific network voodoo to be set up - link aggregation and Jumbo frames - and more than one edit station requires an expensive managed Switch.
Even with all that lot it will probably need management software to ensure a reliable data stream...

But its a lot cheaper than a full fibre SAN.

Its a costly business...

We looked into many possible solutions for a separate server/raid solution for our 2 main edit suites (Each has about 2T online), but even for realistic 'small' one (starting with say 2 to 4T) to allow us to handle 'proper' HD such as HDCAM via fibre then there is a 5 figure price tag. We worked out we would have very little change from £20k. Too big a commitment for us in this years budget! :(

For my Apple laptop I use a time capsule... brilliant... fully automated grandfather,father,son backups with no intervention required. £199 for 500Mb and £329 for 1T. It also works as a wireless router and print-server. I think it will work with PC's using XP too... worth a look.

Just to push this back up. Have a look at Windows Homeserver, difficult to get hte s/w if you aren't an ms developer/partner but it really is quite cool..........
