Onboard raid adapters, which are they?
 

recently majority of motherboards on stores comes with onboard raid adapter, such as Intel motherboards and AMD motherboards.

the question is, i need to build systems with hardware raid (both raid1 and raid5), so are these onboard raid adapters classified as "software raid" or "hardware raid" solution?

cheers!

They are hardware raid but pretty low end, also they'll be for SATA not SCSI

cheers

Just to add something; from a youtube video that showed benchmarks of different raid setups on an internal and external raid cards; the summary was that it was discovered that a RAID 5 would perform much much better on a dedicated.

thanks for the response guys,
but then does that mean that if i buy one of these kinds of motherboards, say; an AMD or Intel and build it with raid1 (with windows7).

the question is,

1,
where does the raid1 (configuration) resides?
i mean will the raid be set up in the BIOS (prior to the OS installation), or will it be set up within the OS (after the OS is installed)?

2,
if one of the disk dies out can i be able to just replace it with a new disk, re-sync it with the existing good one and get going?
or will i have to re-install OS first and then rebuild the raid?

these are the areas i want to get very clear on, sorry i'm new to this.

The raid config will reside in the bios or in the raid controller nvram, the OS is unaware of the underlying disks, it just sees the raid volumes you've created as physical disks

cheers

thanks for the response - now understood!

but how about the second question?

thanks

You should just need to replace the disk. The RAID controller should sort out the syncing. The only control you would use is to set the re-build priority via the RAID setup, high and you would degrade the I/O data throughput which could be noticeable, Low and the rebuild would take longer but with less of an overhead.
I'm used to working with HP SmartArray controllers, I assume that Motherboard embedded ones should operate in a fairly similar fashion though I'd guess on a lower level - maybe can't set priority, adjust block size, etc.

Hope this helps! :)

Play Bonny! :hattip:
