Question about Raid Performance
-
Assuming RAID1 because you don't seem like the YOLO type, I can't imagine your performance would jump by using hardware.
You'd use hardware when bench techs are involved or you need hardware capabilities not provided through mdadm.
-
Also worth noting this card is older, Server 2008 is the last Windows OS that is supported by this card within their own marketing details. (It could be updated, but I didn't bother checking further).

h310
It is a precision system, so he is probably not running a server OS. Or is he?
-
@wrx7m Its my workstation. I won't be pushing the machine most likely. Just consider it a theoretical question. If the machine was going to be pushed to its limits, would using this card make sense?
-
@wrx7m No, not Windows server anyway.

Yeah this is their business line, so it likely isn't meant to be used as a server. Not that that matters though.

No, because the CPU on this Chip is older than the CPU you have in the unit. Your performance would likely suffer.
-
@DustinB3403 ok that makes sense, thanks!
-
Now if you, @jmoore wanted to make this system scream. Set it up as RAID0.
And just have a good backup solution in place.
-
@DustinB3403 Thats what I have now on Fedora.Yes its very fast.

You currently have an mdadm RAID0 and want to install hardware to try and make it a faster RAID0?
-
@DustinB3403 lol umm yeah, I have never used hardware raid before so just wanted to see if I was missing anything.

You're missing some bench tech features. Things that, you with this particular case do not matter in the least.
Since you can't pull a drive without opening the case,
needingwanting blind and hot swap are moot points to even consider. -
@DustinB3403 Yeah your right, I don't care about those things. Its just my workstation. I have stuff backed up to san and I have an updated image ready to deploy for my system in case something breaks.
-
What are you using for your backup solution?
-
@DustinB3403 I don't have a backup solution per se. I save files directly to my network share and I have a complete system image saved on the network as well. I update the system image about once a month. I don't have any important data on my machine. I use browsers based things and email. I test apps for issues reported by users.
-
@jmoore that would certainly work. No need to make things more complex if there is no benefit.
-
@DustinB3403 Cool, thanks for the input!

@jmoore said in Question about Raid Performance:
I got an extra perc h310 card and wondered if I would get better performance using that instead of mdadm.
Not even close. MD RAID will destroy any RAID card. Especially a super low end one with low cache and known implementation problems drastically impacting performance.

RAID 1 or 10 performance can be cut by more than half, in fact!
