Hello.
Since we often with multiple computers s.einem Project work, I need an external hard drive enclosure, which I can install many plates ... and I will of several computers (ie state and notebook computers)! at the same time! can access it? So do not simply an external hard drive.
Do you have experience with NAS systems? Can I zb! At the same time! Of my MacbookPro via eSATA and stand with my computer via USB 2.0 to access the disk .... Or does it all then the network cable?
What kind of housing would you suggest?
Thanks and love greetings
Mleko

Simultaneous access is only through networking technology - and is even with the high quality NAS solutions with Gigabit LAN is too slow for decent video editing.

Attention, theory of everything:
The magic word is actually NAS. These are "Network Drives" and therefore run on Network Connections. Basically, you can a server synonymous with sufficient Plattenkapatität up.
It is important to note that the whole should be a practical and theroretische threshold. A DV stream has 25 Mbit / s. With 100 Mbit network cards you can, taking into account additional data and collisions with 2-3 simultaneous data streams expected. The number 4 is not reachable, because the data with increasing number of data collisions increases. Eventually the network will only have a collision with the company.
If you have two parallel running clips in a timeline, you would be the network port schnon busy.
Therefore, the NAS or the server in any case on a 1000 Mbit network card and it must have a matching switch also available. Ideally, the workstations are synonymous appropriate network cards, so that synonymous times a timeline with three or four one above the other video tracks can play ....
Under this assumption, you could two or three PCs with quite a NAS operate if there assembled parts (especially hard disks) are fast enough and the timelines in the project a degree of complexity not exceed.
A low-cost NAS box of this slide will probably not meet requirements ...

It is synonymous with NAS 2x Gbit connection. Can I imagine that there's more.

G-Tech building and good in the industry synonymous widespread devices.

The network speeds but are gray theory. In a "100-Mbit Network can be reached in practice, maybe 40 Mbps between two fast computers.
Some cheap NAS enclosures are even at about 4 Mbit limited - although with 100 MBit advertised. The borders s.Betrug, the unsuspecting buyer is so confident that it with a fast hard drive at least 100 MBit network out of the can, and this is the truth by a factor of twenty (!) Lower.
With Gigabit LAN is a bit more, but far from being synonymous with the most modern hard disks. In any case, so the network a bottleneck - and with cheap NAS enclosures anyway.
Whether or not speed is, of course depends on how and what to cut. DV streams are no longer necessarily the measure of all things.

Well - is mainly with the AppleProres (HQ) worked.
Will the fact that one example of a calculator on the eSata External accesses, and the other via USB? At the same time?
Antwort von tommyb:
No, generally. does not work that way.
What remains is really just a storage connectivity via LAN.
The cheapest way is as already mentioned a server - perhaps even in self including RAID 5th Other RAID modes are hardly worth the LAN bottleneck.
In each case, there are motherboards out of the price segment, the 100 + euro have dual Ethernet. Then you have a look at 2 Gbit, ie effective then perhaps 50% throughput. Depending of the size of the files is at a multiplex in the entire knee walk - 2 Gbit should all but in contrast to the other connection options ausreizen better.
The entire network must, however, in the Gigabit run. that is synonymous to the calculator to access should be at least 1 Gbit / s to create. 100 Mbit / s per calculator gives perhaps purely arithmetically 12MB, effective but not more than half of which is absolutely not sufficient for Pro Res
NAS enclosure with similar characteristics, such as a server in this case would be significantly more expensive.

for God's sake ... what a jungle ..
werd mich mal unsehen what s.besten fit for me.
many thanks for the reply!
