Continuation of the original RAID is "Redundant arrays of Inexpensive Drives" but later called "Redundant arrays of Independent Drives" (Intel in the literature) and have used is "Redundant arrays of Independent Disks" (in Microsoft literature). Http://en.wikipedia.org/wiki/RAID to see in detail the definition RAID.
Principal difference
Before we have to know that the definition of RAID H / W and S / W is not just the hardware vs. software, but merely more than that. The principal does is as follows: Hardware RAID: is always a disk controller to which you can cable up the disk drives. RAID Software: is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware. Thus, clear differences in both methods and I can briefly simpulkan the advantages and kekurangannya as follows:
Comparison of RAID SOFTWARE and HARDWARE
1. RAID S / W price is cheaper because the feature is generally an internal OS. But this time have a lot of M / B are available and include RAID Card PCI RAID cukuo cheap
2. RAID S / W RAID while burdening the CPU H / W has its own controller.
3. RAID S / W generally slower. Note, if using RAID Server B & S / W but have a CPU with a high speed so it can be faster than a server with a RAID using the H / W.
4. The process of booting and shutdown a server with RAID S / W takes longer.
5. RAID H / W does not generally have problems with booting on RAID disk mirroring, while S / W possible the modifications require boot files or boot disk that can help to function properly. Experience shows me some of the server can not boot directly from the secondary drive (mirror) after the primary drive fail.
6. RAID S / W because it works with kernel O / S so easy to upgrade while in RAID H / W requires replacement hardware if upgrading the firmware is not possible.
7. RAID Configuration S / W is easier because it is a part of the OS. RAID configuration while the H / W must be done in 2 stages: the BIOS and Installing the S / W RAID support H / W's. But because the S / W RAID on the H / W designed specifically use the easier and more interactive.
8. RAID H / W generally have the ability to determine-spare disk, the disk backup if there is a damaged disk in a RAID, so no need to manually change the disk that is damaged.
For the success of a RAID system then I highly recommend to select the RAID H / W because the price that is affordable even available RAID H / W PCI card form if you do not want to change the M / B you. But if not possible then select the RAID S / W rather than not at all!
TEST comparison RAID H / W and S / W!
In the experiment with the Windows 2003 Server R2 on a server with Intel core2 Quad 2.8 GHz, 2 GB Memory, 500 GB HDD then take more than 12 hours to create a RAID 1 (mirroring) synchronization reach 100%.
While using RAID H / W Intel Matrix Storage only need 2 hours only! In addition, because RAID H / W is configured at the BIOS level of the process (synchronization) RAID disk during installation can be done so that the OS automatically sync directly!
