Swapping Drive To Another RAID Controller

Interesting tidbit you may or may not know. (I am sure you do.)
While the H310 DOES support single drives non-RAID), the H710 does NOT. You can use a single drive by creating a single member RAID0 array.
Not that you wouldn't always use RAID in a server. Just thought that was interesting.
Good to know with my predilection for software raid, in that specific usage case an H310 will be just fine should I need another HBA.

After being a member here at ML, I have sworn off the H310.
Going to sell mine on eBay rapido!

That's actually standard.

It's perfectly good if you don't want any hardware RAID from the controller

The results on my new EDGE SSD (from xByte) Raid 1 array:
-
MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s]
-
KB = 1000 bytes, KiB = 1024 bytes
Sequential Read (Q= 32,T= 1) : 1185.227 MB/s
Sequential Write (Q= 32,T= 1) : 488.470 MB/s

This is good, right?

Another H710 question...
There are two areas I have questions on.
One is Read Policy.
The SATA array is set to "No Read Ahead"
The SSD array is set to "Adaptive Read Ahead"One is Write Policy.
The SATA array is set to "Write Through"
The SSD array is set to "Write Back"Are these settings determined by the type of disk?
-
I'm not sure if it detects and changes based on that or not.

Is it possible those settings were set by the H310 and just migrated to the H710?
What SHOULD the settings be? What do they even mean?

If you swapped the disks from one to the other, absolutely. Did you have to recreate the RAID arrays?
