Frage von dickeraugust:
Hello everybody,
have been a week of the company fantec me a raid system (MR-35DU3) with 2 x 1TB WD hard drives fitted. everything's going great and fast. But now my question:
if I fall from this raid system and partitioning of the hdd, the raid system, the data on the new hdd esetzte reflect correct? or should I rather not partitioning and leave everything as it is?
I have never had a RAID array in use and therefore no experience with RAID systems for daily life.
Greetings

Hi Andy,
then you is not synonymous probably aware of what is Raid 0 and 1 and 5, etc.? You have yet to know how you have set up a raid ...
In summary:
RAID 0 distributes a partition to two or more hard disks. Also, all files are distributed on both hard disks. Purpose of all: fast reads because all hard disks read simultaneously. In the best case for two hard disks you have half the access time in Comparison to a.
Raid 1 mirroring means. Access times do not improve, but it is all the data twice. Raid 1 is therefore of security.
Raid 5 is, a plurality of hard disks is redundant. On the basis of a mathematical method, the data is saved so that a hard drive could fail without any data loss.
Then there are mixed forms.
In general, use is made of in the home for financial reasons Raid0. This one is faster, but the failure of a hard drive would automatically mean complete data loss. Therefore, one must take care to secure themselves, eg by external backup hard drive.
Besides the question of safety, it is a question of capacity.
Raid 0 is approximately the sum of individual capacities. Raid 1 is the size of a single hard drive. With Raid5 it depends on the configuration of. Take for example, 5 hard disks and has a capacity of 4 This is Raid 5 safe and fast at the same time.
On the issue of partitioning, if the drivers are installed and the RAID system is installed, it looks for the operating system as a single hard drive. So you simply partition arbitrarily. The requirements of the interface program should be considered here.
Antwort von Auf Achse:
Hello!
Raid 5 will appear with his redundancy than the cheapest in price - performance ratio. I had it configured, but the plates were in this configuration, the average operating too slowly with the simultaneous writing and reading. This has to do with the redundant disk. All detailed infos can be found on Wikipedia.
But why do you want to partition a raid Association again? The advantage of the raid is, amongst other products that you finally have a big plate!

Antwort von Hans-Joachim:
The raid was synonymous composite developed for speed and security, because of hard disks are 1.5 or 2 TB size is synonymous with no raid.
By the way, should be synonymous RAID5 system be much faster than a single disk. For example, in a system consisting of 4 or 5 hard disks to read the crowd is spread over several hard disks, each of which related to that individual a small amount of writing. The same effect occurs when reading.
I have just checked that Iomega offers RAID systems with 2 and 4 hard disks. A RAID 5 do, in my view with 2 hard disks no sense at all.
The indication in August of thick-called model number is a system with 2 hard disks. Whether there now created one or more partitions, hanging from many of things. Is it still as a separate (system) hard drive or the OS is with the raid? If the latter should necessarily be more partitions set up, one for BS and at least one othe for all data.
When installing the OS on the raid system I give only to consider how the backup is to look like the system partition. It is easier with such as a separate 500 GB hard drive for OS and a RAID 0 array for the rest
Antwort von thos-berlin:
With two hard disks can not build a RAID 5. So this is either RAID 0 (capacity and speed gains) or RAID 1 (disk mirroring security).
I would not partition one way or the raid.
My suggestion would be:
Operating system and software on a normal drive. The finished installation as an image on another disk secure. All successful make system changes (updates, software installations), a new image. (Tip: with the image continued to work then you can see immediately whether the image is OK Otherwise, lurks a nasty surprise later...
Effort 2-3 small hard disks.
The raid only for data use. In Raid 0 still a regular data backup is not recommended for Raid 1 (disk mirroring).
Antwort von LarsProgressiv:
Hi Thos,
I hope that was not meant as it was written:
[...] In Raid 0 is still a regular data backup is not recommended for Raid 1 (disk mirroring). I think not only one but more data security expansions always recommended no preference whether employing a RAID array or not.
Greetings
Lars
Antwort von thos-berlin:
Maybe put it rather unfortunate:
In Raid 0 Raid not the "security" has. Regular data backup is always safe, you will suffer the loss of any data loss. (Ideally more than one generation)
When you have a Raid 1 "eingabaute" through the mirror plate. Thus, the fuse is then installed the latest nortwendig when the first disk gives up the ghost. Then you have "time" to make the backup, or quickly replace the broken plate and make the recovery (or have) - or both.
Regardless of the systems used is of course a backup always be appropriate, several of backups are better.
It's all a question of entitlement, charges and benefits.
Antwort von Hans-Joachim:
Everything described before, but perhaps is twice better.
On the question, Raid 0 or 1:
Who is a RAID system with two hard disks purchased and installed, but should be dusted with the peg bag, if he makes it a Raid 1 system. It uses the speed advantage and selects Raid-0.
The security, the raid has 1, are brought out by a simple external hard drive. So you have both: more hard drive at full speed security drive failure.
Antwort von tommyb:
Well ... with a RAID 1 you have it much easier if a plate over. Then worked so long next s.System exchanged until the defective drive is and then the system is again secure.
In the event of a RAID 0 one first has a non-functioning system and must be back behind the play all that shit yet. But who has time for that patient and customer ...
Antwort von Hans-Joachim:
So of course not. There have been different sides of the recommendation to use operating system for its own hard drive and to store only the video projects on the RAID system. In this case, it goes to eg 2 x 1 GB.
This 2 GB, you can easily back up an external hard drive. Since there is no data loss when properly secured.
The operating system you can drag and drop an image on one of the other boards. The next was synonymous already recommended above. To keep you safe on the page.
