Hi all -

 

Generic question - is there a reason to prefer a RAID HBA running in IT mode rather than a plain old SATA controller card assuming that we're using SATA disks?

 

Specifically - I have a Vantec UGT-ST655 that seems to be working fine, but people keep telling me that there are some unseen problems to be aware of and that I should return it and get an LSI HBA flashed to IT mode.  Is there an advantage, in general?

 

Thanks in advance!

Hi, not really.

One advantage would be that HBAs generally support more drives. But otherwise a good SATA controller should work as well.

Can't vouch for that model as the manufacturer does not indicate what controller is used. From the images, it does not seem to use a port multiplier.

 

It might be visible in your diagnostics though.

Thanks

Thanks very much - a little sleuthing and differentiating the various interfaces that are installed, it seems as if this one is:

 

04:00.0 SATA controller [0106]: JMicron Technology Corp. JMB58x AHCI SATA controller [197b:0585]
    Subsystem: JMicron Technology Corp. JMB58x AHCI SATA controller [197b:0000]
    Kernel driver in use: ahci
    Kernel modules: ahci

 

so on the list of recommended controllers, I gather.

 

 

Best regards,

Neil
