Aspire V3-574G: relatively slow HDD in the place of optical driver (UDMA/MWDMA)

Hello again,

 

My system is running with an SSD in the place of original HDD, and the same HDD (Toshiba 1TB) in the place of the optical driver. It's working fine but it seems that HDD is a bit slow.

Looking at the DMA type using Aida64, there is a strange thing: sometimes it's working in UDMA 5 mode (OK !) and sometimes it is switched to MWDMA 2 !!??

SSD is sometimes in UDMA 6 and sometimes in UDMA 5.

Weird, no ?

 

I think it's a question of harware and as the bios is very limited I imagine there is nothing to do.

Anyone ?

Thanks
