When do i need a raid controller

Many of our industrial and embedded clients utilize RAID arrays in their projects in order to protect important data and enhance the operational speed of equipment that depends on information being read from and written to hard disks.

While there are many forms of RAID involving differing numbers of disks and various combinations of features, the vast majority of the questions we receive involve the three simplest modes. Of course, a dedicated controller will likely come packaged with more advanced features and capabilities to allow for more intricate control of array settings. Even with the enhanced on-board capabilities of modern systems, there are still a number of instances where a dedicated controller is a sound investment.

The most obvious situation stems from the fact that not all motherboard support on-board RAID. If you need to set up data redundancy or stiping on a legacy system, installing a RAID card is a simple procedure that can have you up and running quickly. We occasionally work with clients who are interested in implementing more complex array setups involving multiple hard drives in various configurations. When executing the other forms of RAID additional modes may stripe data at the bit or byte level paired with duplication we often recommend a dedicated controller to ensure proper implementation and allow for more exact control over array setup and maintenance.

Every redundant array application will have its own variables and requirements. The best way to determine if the included RAID functionality of a system will be sufficient for your needs is to speak with one of our technical sales experts.

Be mindful of hard errors which are the reason that RAID no longer lives up to its original promise. If one of the drives fails, then during the rebuild if you get an error — the entire array will die.

Deep Blue Distinguished. Sep 6, 42 0 18, 0. Or it was automatically detected and no RAID drivers were needed? Any advice, opinions, idea or replys will be greatly appreciated and many thanks in advance. Oct 9, 48, 2, , 9, Deep Blue :. Sorry for all the questions, I'm a huge noob when it comes to these stuff.

Many thanks in advance. Jul 1, 1, 2 20, Jul 7, 3, 0 23, Backup often. Dereck47 Splendid. Jan 20, 3, 0 22, Raid-0 writes alternating stripes user defined like 16k up to k stripes of data rotating among the raid-0 member hard drives. In theory, you can then read each of the hard drives in parallel to improve sequential performance.

Raid-0 has been over hyped as a performance enhancer. Sequential benchmarks do look wonderful, but the real world does not seem to deliver the indicated performance benefits for most desktop users. It depends on reading a stripe of data simultaneously from each raid-0 member, and that is rarely what we do.

The OS does mostly small random reads and writes, so raid-0 is of little use there. There are some apps that will benefit. They are characterized by reading large files in a sequential manner. Dec 13, 0 18, Sorry but I have to post I run my games in a 16KB stripe raid 0 array with 2 samsung 1TB hard drives and I must say, games load incredibly quick.

Some games also write and read files from the hard drive on the fly, so the extra performance will be worth it. If your scared of losing data, back it up. Aside from booting the comp or starting programs, sometimes when I don't use my computer the HDD sometimes runs by itself assuming it's defragging and indexing files, does RAID 0 also help speed those up too?

Since I usually prefer to wait for my computer to finish indexing the HDD or what ever it's doing everytime my computer has been idle for a while, the waiting for it finish is kinda boring and made me wonder would RAID 0 speed it up.

RAID 0 is not raid, it is deliberate damage to your computer.
