Is changing to AHCI can degrede performance of optical drives?




I am planning to buy SSD later this year. I have Biostar TA880G HD motherboard with AMD 880 chipset. Today, as SSD will need ACHI enabled, I changed sata type to AHCI in bios and now Imgburn see my drives like this:

I 17:33:32 ImgBurn Version started!
I 17:33:32 Initialising SPTI…
I 17:33:32 Searching for SCSI / ATAPI devices…
I 17:33:32 -> Drive 1 - Info: Optiarc DVD RW AD-5260S 1.00 (F:) (ATA)
I 17:33:32 -> Drive 2 - Info: HL-DT-ST BD-RE BH10LS30 1.00 (E:) (SATA)
I 17:33:32 Found 1 DVD±RW and 1 BD-RE!

Before this change, both of my drives was identified as ATA. I have no problems with TRT, just don’t want to start any burn until I know that this setup is OK.

Thanx a lot!!!



“IDE mode” is the most compatible. Especially with LG drives who are often very picky.
Modern AMD based motherboards should have the Bios option to set the operation mode of two Sata ports (usually port 5 and 6) to IDE independent of the other four.
This seems to be already the case, so you might move your LG drive to one of the ports that is still in IDE mode.



Thanx a lot!!! I will try this tomorrow, and I will let You know what I did.



I changed LG drive to Sata port 5, and Nec stays on Sata port 6. Now, both drives are ATA. Imgburn log:

I 10:52:51 ImgBurn Version started!
I 10:52:51 Initialising SPTI…
I 10:52:51 Searching for SCSI / ATAPI devices…
I 10:52:51 -> Drive 1 - Info: HL-DT-ST BD-RE BH10LS30 1.00 (E:) (ATA)
I 10:52:51 -> Drive 2 - Info: Optiarc DVD RW AD-5260S 1.00 (F:) (ATA)
I 10:52:51 Found 1 DVD±RW and 1 BD-RE!

Now, on this picture it is clearly that I have two “ATA” channels (motherboard is Sata only). So it seems that both drives are on same channel. Will it be smart to put them in separate channels? My guess is that port 4 will be ATA channel 1.

Thanx a lot!!!


Looks good now.
My guess is, that ports 1-4 are running in AHCI mode. You might check the manual of your motherboard to make sure.



Ok, thanx for the answer!

I checked manual, but there is no detailed info about this (IDE modes, there is just about bios settings). I will try to search for info about 880G chipset. I tested both drives, it seems OK.
