RAID ? Can You Use A Independent HD For Your System Disk With RAID Array For Data?
Thanks. Disadvantages Write data transactions are slower than RAID 5 due to the additional parity data that have to be calculated. Software RAID can also comprise virtual RAID solutions offered by vendors such as Dot Hill to deliver powerful host-based virtual RAID adapters. RAID-systems can be used with a number of interfaces, including SCSI, IDE, SATA or FC (fiber channel.) There are systems that use SATA disks internally, but that have a FireWire or have a peek here
Another benefit of RAID 5 is that it allows many NAS and server drives to be "hot-swappable" meaning in case a drive in the array fails, that drive can be swapped If you reside outside of the United States, you consent to having your personal data transferred to and processed in the United States. The user thus has to search about restoring a computer, which to my opinion requires just as must research than the time spent on understanding back-ups. Join the community here.

Avoid RAID-5 or -6 via software though (big processing overhead) and DON'T FORGET to BACKUP EVERYTHING before experimenting. There are also other, non-standard RAID levels. Most operating systems—including Windows—also give users the ability to configure what’s known as software RAID. Raid 50 My thought is that for additional back-up security, I could even switch out one of the removable/replaceable drives in WD "MyBook Thunderbolt Duo 4TB Dual-Drive with RAID" the on a weekly
But in situations where you cannot tolerate downtime, this will keep you running until you can make repairs. What Is Raid Technology Windows 8 introduced Storage Spaces. This technology is based on tensors and promises to put all other RAID to shame.

That same backup on a good raid with zfs is very unlikely to ever go bad. http://hcsprogramming.com/raid-1/two-raid-0-and-one-non-raid-drive.php The Dobro was always causing problems so backups often didn't happen.

Reply Pete Marovich says: March 19, 2016 at 1:12 pm Seems reasonable to me. This makes the drives the same age, and subject to the same operating conditions and amount of wear. Now when talking about your RAID1, you say "If one of the 3 TB drive crash, you will still have your data on the other one." Yes that is true, UNLESS http://hcsprogramming.com/raid-1/raid-1-array.php If the 3 TB drive (this is actually now a 6TB drive) crashes I get a new one and back up the system again.
Reply Pete Marovich says: October 15, 2015 at 8:51 pm You apparently did not read the post closely. Raid 10 Somehow, I had lost the data from it. By using multiple disks (at least 2) at the same time, this offers superior I/O performance.
I have 4 drives, 2TB each, total 8TB.
In general, a RAID-enabled system uses two or more hard disks to improve the performance or provide some level of fault tolerance for a machine—typically a NAS or server. The terms 1-disk or 2-disk redundancy refers to the number of drives that can fail with the array remaining usable. Link Ali Khan September 17, 2015, 11:31 pm I have a Dell power edge server 2u, with 4 SAS hard drives. Raid 5 Vs Raid 10 I am PC so if that is the case I will need to explore some more).
If two hard drives die in a RAID 6 configuration, you'll still have all your data. If your time machine backup software fails or corrupts during the backup, both sets of data will be corrupted. Jul 28, 2007 Guys, Is it possible to use a separate hard disk for your OS and programs with data storage on a RAID Array consisting of two (or more) identical this contact form I've had a Drobo, it was a nightmare, finally turning into a brick.
When using RAID, you can either use "hardware RAID" or "software RAID." With hardware RAID, a hardware device in your computer does all the RAID work. RAID 10 (RAID 1+0): Combining RAID 1 and RAID 0, this level is often referred to as RAID 10, which offers higher performance than RAID 1 but at a much higher With 4 disks, you will only loose 1/4 of your HD space. Aftab Alam says: April 5, 2016 at 7:42 am What an excellent explanation of RAID…..
No redundancy ( no mirror, no parity ). Any solution you can suggest? says: September 7, 2011 at 9:16 pm One additional ques: I assume RAID 5 is the same as RAID 4+1? What does the second scratch disk contain?
It gave me the pause I needed to do some research first!
