Fast drive for niche applications, suitable for high security requirements

The drive is fast, in fact. It is particularly in the Amazon described by the manufacturer or niche (applications where fast drive access time saving). I had bought it as a storage giants and wanted to take my dataset it. I quickly realized: for it is not suitable. The cluster is set to RAID 0 and thus not the security giant. Reconfiguring to RAID 1 is not possible. A second cluster of the same variety should serve as back-up drive (Time Machine) are used.

Now we come to the first major problem. These drives run on the Firewire bus system despite its own power supply with a large data throughput are not stable, they separate from the computer and this means due Raid 0 lengthy repair of data capture to data total loss. The first attempt at a solution was the interconnection of the two clusters for RAID 0 + 1 multi-project (RAID 01 with four plates [2 clusters] using the software Raid of OSX Mavericks).

Second problem: Good thought, but within a short time a huge problem: getting off of individual clusters on the Firewire bus led each to almost four days of recovery sessions: unacceptable! Especially because in the period of recovery so at any time may occur a second fault on the intact cluster, and that increases the risk of data loss total.

First solution and third problem: The hard drives on the Firewire must independently switched on and can be switched off, thus remains only a FireWire repeater / hub. I chose with my 3 Firewire disks / clusters to Delock 4 port IEEE 1394b FireWire Hub / Repeater. The independence of the storage media of one another was thus ensured. The problem with getting off the individual G-Technology Cluster remained.

The final solution for the time being: The stroke had to be provided with its own power supply (for he is also set). What are the minimum requirement for these power for stable operation, I can here not specify, because my solution was a pretty special: I use a battery backed up supply from old shortwave radio time, and now the RAID 0 + 1 system works from the two clusters initially properly.

Certain considerations should do just before buying in order to avoid the experienced disaster.

Conclusion:
- These clusters are clusters for fast video and image processing and the like. But here you are with this enormous capacity of 6 TB in the professional class.
- For pure non-mirrored data storage and backup media as they are unsuitable.
- In Firewire composite there is a risk that for any reason whatsoever "release" this cluster. Cascading on Firewirebus is completely unreliable. Here only operated over a reliably supplied FireWire Hub / Repeater.
- Who has two of these clusters, can produce a relatively safe system state over a FireWire repeater / hub with sufficient own power supply.
- For pure Daisychaining the Firewire bus, the cluster is unsuitable.

Was my mistake and I publish this review with the hope of others who have similar problems on Firewire help.

1 star trigger for the cluster with respect to the unreliability is justified.
