my arita disks fail verify at 50% at 4x speed, cant test 2.4x as my 224b doesnt support that low burning, orderd me some verbatims
I've had a look through all six firmwares using MediaCodeSpeedEdit (MCSE), all six firmwares have the same entries in their media code tables (with a new "MKM-0a3" replacing MKM-003 in the iXtreme versions) with only one exception: the iHAS-324 and iHAS524 "know about" one additional DVD-RAM disc that the others don't.
Whether the writing strategies differ between the drives though, I don't know. In case you fancy crossflashing to a different version and trying that out, the firmware details are:-
iHAS-124 B AL0S 2011/08/11 10:09
iHAS-224 B GL0A 2011/05/12 13:37
iHAS-324 B AL1B 2011/09/06 15:01
iHAS-424 B GL1A 2011/05/12 13:28
iHAS-524 B AL2A 2011/09/14 14:47
iHAS-624 B GL29 2011/05/10 09:24
If you don't mind losing LabelFlash I'd recommend crossflashing (read the guides) to an iHAS-524B which appears to be the newest of the lot.

You need an Xbox 360 Benq/Liteon drive to rip with new 0800 fw installed on it, - as per release nfo, to rip xbox 360 games.
Or a Philips DROM6316,
