Re: Z77 Extreme6 motherboard mounted eSATA connector has problems, drive disconnects

From the Z77 Extreme6 Online Manual
Code:
If the eSATA3 port on the rear I/O has been
connected, the internal SATA3_A2 will not funtion.

As does my ASRock 990FX Extreme4 manual. Yet my Gigabyte UD5 manual makes no recommendation as to E-Sata 6Gb/s cable length.

Cable length is indeed spec'd at 2m, maximum length, and again assuming a shielded cable of suitable quality and construction is used while external influences are minimized. Inside our case the cabling is "shielded' by the case itself. Move that cable outside the case as E-Sata does and it now becomes subject to the many external influences/interferences our homes and many "must have' devices emit. What my home exhibits for influences/interference or lack thereof is no way representative of what yours may or may not exhibit, thus I believe why the 1m length is declared in the manuals. If you will, one of those manufacturer "Cover your a**" statements.
In essence, outside the case the cable becomes an antenna for EMI and RFI. Controllers do not like dealing with EMI and RFI interrupted, degraded, and or corrupted data streams. The shorter the cable the less chance for it to occur in the first place.
hehe, and the strange part is they, when mounted on the motherboard proper, are tied to a single PCI-e lane rated at 5Gb/s. Slot mounted add-on cards, with the exception of PCI-e x1 cards, aren't limited.
