LaCie drives fail like other drives – they heat up past their tolerance for too long and then they die. The Porsche and D2 drives feed into that trend with poor cooling characteristics.
Plus I bring this up again for fun – 3.5″ drives are not the most robust of the lot anyway. The current crop of 2.5″ drives can survive more jolting – 250Gs versus just over 60Gs of operating shock for 3.5″ HDD. For me, that makes them more attractive (but expensive) for travelling.

I’m glad to hear that transfers were fairly quick with 5400rpm drives – they definitely are cheaper. Someone earlier had posted that the faster the drive, the quicker the download but I have no direct experience either way….
The 2.5″ vs. 3.5″ drive debate really came down to durability. The current crop of 2.5″ drives can survive more vibration – 250Gs versus just over 60Gs of operating shock for 3.5″ HDD. That seems to make them more attractive while travelling.

(at the bottom of the page)Did you use the P2 Store to avoid downloading straight from the camera or was there another reason? That does sound like the best way to go, I’m just trying to completely understand the logistics of it.

We use two of the Terrablock 12D over 2Gb FC thru a switch for 8 PCs and a Mac.
It is pretty simple to administer and whenever I do have a question on it, I can get an engineer on the phone. The system is low-maintenance and basically a huge disk that you partition and share among your clients. Unlike some of the other lower-cost SANs, you can run two uncompressed HD clients on it. For compressed video, you can have up to 20 clients.

Rather than a P2 Store, how about a firewire dock that can accept individual 2.5″ notebook drives (like a Wiebetech DRIVEDOCK+)? If you could ensure a postive lockdown for the drives and used Wiebetech’s metal backplates to safeguard the drive’s electronics, this would be a cheap and unlimited download solution. All questions of how big a drive capacity you can use would come down to — how many P2 cards can you download before you get a “too many folders/files”-like error? Anyone know?

Also give the Terrablock from Facilis Technology a look.
http://www.facilistech.comThey use 4gig FC for HD and have very good tech help. We are running 2 Terrablock 12D servers with 8Tb of storage supporting 8 SD cilents over a switch. You can connect a few clients (4-6 maybe?) without the switch.
$9K is a low number to be starting a Fibre Channel network. However, if you start with one of the larger RAIDs, you get more performance in the long run.

Six DV clients is not a lot of bandwidth for a SAN. Our Terrablock server shows no slowdown for 5-6 clients and support up to 12 dual-stream clients at DV resolutions.

Sorry – yes, 19.6 Terrabytes. We just use local drive(s) for dissolves and any effects that won’t be shared. It keeps the volumes cleaner. We run the Terrablock with offline suites at the moment so single drives are fast enough. We are adding the Online suite plus five more offline rooms later this month.
