Server:  SBS2008 FE (64bit), Intel MB S3420GP, (New LSI 9211-4I w/ (4) new (ST2000NM0033) 2TB Drives in a RAID 10.

Device manager is calling out the LSI card as a 2004 Spitfire-stor card (LSI does not know why)

Performace is slow.  

Updated Bios on LSI Card and ensured latest 64 bit driver in place w/ LSI Tech Support

In resource monitor Disk  "highest activity monitor " is pegged most of the time.

Not sure what to do from here. Running out of ideas.

Slow is relative.  Please provide some specifics, like exact RAID config as defined by the controller, and filesystem settings/partitioning to start.

RAID 10 - 4 drives = logical drive of 3.635 TiB    Drive C: 250GB   Drive f: 2 TB  

WHat do you want to know about the filesystem settings?  Not sure what info to give.

What else for info can I get for anyone?

I assume you took defaults when making filesystems, correct?
on the RAID what is the chunk size  (look in configurable settings and see how many KB each I/O is on the disk)

But biggest thing you probably have wrong is that your controller is probably reading/writing 64KB at a time from each disk, where your NTFS settings are probably 2KB per io.

This will make I/O highly inefficient, and small block and random I/O such as in database will suffer.

Ideally, you want the controller to read same I/O sizes as NTFS. Anything different is inherently inefficient.  Way it is now, if you want to read/write only 2KB of data, your disks are doing 64KB at a time (or whatever settings are in theRAID

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

The original drives in a raid 10 failed. So a new controller and hard drives were installed.

Then the backup was restored.  

How do I determine what the drives read/write size is or is it only determined by ntfs?

I will check the raid controller.  Symantec system recovery formated the drive. and MS states that server 2008 defaults to 4kb

In the end, over a time it settled in and works quite well. I did not make any real changes.

Seagate also sent a disk to change the firmware but it was without guarrentee that the data would be ok. soI did not use.

Not sure how to close this. This thread should be deleted since it ended up resolving itself.

No real resolution and the other sanswers did not solve the issue either.
