But you could use a RAID (4,5 or 6) as the backup drive if you really have to have both 8TB drives online and backed up.

RAID 3 is seldom used except in the most specialized database or processing environments, which can benefit from it. •RAID 4 is a configuration in which disk striping happens at the In their June 1988 paper "A Case for Redundant Arrays of Inexpensive Disks (RAID)", presented at the SIGMOD conference, they argued that the top performing mainframe disk drives of the time What does the second scratch disk contain? Raid 5 Vs Raid 10 Rosenthal, M.Roussopoulos, P.Maniatis, T.Giuli, and P.Bungale. 'A fresh look at the reliability of long-term digital storage." EuroSys2006, Apr. 2006. ^ "L.N.

As a result of its layout, RAID4 provides good performance of random reads, while the performance of random writes is low due to the need to write all parity data to Raid 10 If so, mind if I ask what type of drives, sizes and enclosures you're using for each of those. Implementations[edit] The distribution of data across multiple drives can be managed either by dedicated computer hardware or by software. HardwareSecrets.com.

In the heyday of the mainframe, before PCs and the Internet, mirroring data was highly desirable way to backup your data. Raid 6 RAID can be a great way to optimize NAS and server performance and quickly recover from hardware failure, but it's only part of an overall disaster-recovery solution. This is the RAID level ideal for highly utilized database servers or any server that's performing many write operations. Make incremental backups to the Raid 1 backup system Any file you accidentally delete from your main drive will still be available on your Raid1 backup device.

Raid 10

Consequently, such controllers may not work when driver support is not available for the host operating system.[60] An example is Intel Matrix RAID, implemented on many consumer-level motherboards.[61][62] Because some minimal For Windows software SyncBackPro is excellent as its Touch add on software can backup even Android phones. Raid 5 Calculator For day to day recovery from mistakes or misplaced files, a regular backup is better. Raid Movie But I am not so convinced that it replaces RAID 1 for a catastrophic failure.

I am considering adding another iMac 5k to my house but this one to be used as my primary editing machine…still keeping my laptop but really only for portability. http://puchinet.com/raid-5/raid-5-array-on-dell-server.php We finally dumped the network solution and put an additional Time Machine drive connected locally to each workstation. Next a Raid backup unit and as large or as small as you need are available and Synology has been extremely solid from low end to high end. I was only suggesting that Raid 1 is a perfectly suitable medium for backup data. Raid 50

For other uses, see Raid (disambiguation). It's identical to RAID 5, except it's an even more robust solution because it uses one more parity block than RAID 5. Actual read throughput of most RAID1 implementations is slower than the fastest drive. navigate here Edit, and then move to a primary external drive (passport 2TB).

ACM Computing Surveys. 26: 145–185. Raid 1 Vs Raid 5 Arista Networks' revenue rises, while rival Cisco stumbles Arista Networks' revenue rose more than 33% on strong sales of switches and routers. Software RAID can also comprise virtual RAID solutions offered by vendors such as Dot Hill to deliver powerful host-based virtual RAID adapters.

You may want to consider using a real backup instead of RAID1; RAID1 cannot replace a backup, though both cost the same disk space. Software RAID means you can setup RAID without need for a dedicatedhardware RAID controller. If you reside outside of the United States, you consent to having your personal data transferred to and processed in the United States. Raid Computer Reply Pete Marovich says: March 19, 2016 at 1:16 pm The 3TB IS the backup.

Of course if the building they are in blows up then its all gone so offsite is smart. Retrieved 2011-11-10. ^ Dawkins, Bill and Jones, Arnold. "Common RAID Disk Data Format Specification" [Storage Networking Industry Association] Colorado Springs, 28 July 2006. 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. his comment is here Here are some short descriptions of each: •RAID 2 is similar to RAID 5, but instead of disk striping using parity, striping occurs at the bit-level.
