I am looking at getting an HP ML30 Gen 9 and on reading up on the documentation it appears that the storage controller can be set to AHCI rather than RAID mode.


The HP documentation says the following:


 All drives grouped into the same drive array must meet the following criteria:


 They must be either all SAS or all SATA.

 They must be either all hard drives or all solid-state drives.

 Drives should be the same capacity to provide the greatest storage space efficiency when drivesare grouped together into the same drive array.


My question is: does the above apply when the storage controller is in AHCI mode as I would like if possible to run the following:


2x1tb SATA hard disks

2x160gb SSD disks


These would all be mounted in the drive cage.


I do not wish to mirror the above disks or anything like that.  I want a simple JBOD.


Apologies in advance if I have asked an obvious question but I did take a look through the other postings and could not get a definite answer.

The criteria listed is just for drive arrays setup on the RAID controller. It does not apply to AHCI.

Cheers, thanks for clarifying.  Time to go and buy the thing.
