Hardware RAID versus Software RAID

By fmcomputers1 ·
I need some one to help me please I would like to know if I can just go Software RAID and if this will be as good as Hardware RAID and if yes please let me why and if its not a good Idea please let me know

I personally would splurge on the hardware RAID. The issues with software RAID are that it takes CPU cycles to compute the RAID information (parity calculations if RAID5, or another write to the second drive if mirrored), thus degrading your performance. If just mirroring the drives, you may be ok with software RAID, but I still would prefer to go hardware. As for running RAID5, hardware is the only way to go IMHO.

I'm with CM5400 for the same reasons. Hardware RAID and if you can afford it SCSI controllers and drives.

I am in agreement with both responders. HW raid is much more stable than SW raid, and is much faster and uses less system resources.
SW raid can fail in most of the same places as HW RAID, plus a slew of other places. This can decrease the reliability. If cost is an issue, then a SW RAID solution may fit the bill, but be warned that the server will run slower, and you may generate errors more often.

Need advice implementing PC RAID 1

by brossyg In reply to

I have a Dell Precision 390 with a 975X Express chipset. The chipset has Intel's Matrix Storage Technology (RAID). I want to implement a simple 2 drive mirroring RAID 1 arrangement where I leave the boot drive (C) the way it is (non-RAID) and use the D drive together with a new drive to form a RAID 1 arrangement.

I assume that the 975X is essentially a hardware-assisted software RAID solution, but I cannot find any difinitive information on this. I will either use this RAID on the motherboard, or will buy a separate RAID controller (Adaptec 1220 SA ?), but I am trying to figure out what the hit to performance will be for either of these solutions. Are they both hardware-assisted software RAID? Will one perform better than the other? Will I notice a performance decrease with the motherboard RAID solution?


The only thing that the RAID 1 drives will be used for is a MS Access database (250 meg) that is read/write intensive).


Can anyone adivse?

Definetely hardware RAID. Much more eficient and in case of a HD crash and the operating system goes down, everything is lost. Depending on the hardware, it will let you recover from a failure. Just remember: RAID IS NOT BACKUP! Do not rely on RAID (any kind) to have your data safe.

Hardware vs Software

by ncherian In reply to Hardware RAID versus Soft ...

Just another question to add onto the original...

What about for RAID 0? There are not many calculations involved there right?

I am really considering it from a cost perspective (not security of data/failsafes).

What can Hardware RAID add to make it so much better than Software RAID for RAID 0?
