Actually the description of the item I suggested starts with "This adapter makes it possible to connect different IDE devices, for example hard discs, DVD- and CD-ROM drives to an SATA port on your mainboard", so we're probably speaking about the same thing.
The only difference with the item you suggest is that mine works both ways, so there is no need to get two separate adapters
I use round cables in my computer and I never had problems. Actually, I use 60cm cables, and even if they are out of specifications, these works very well for me. The main point IMO is to use good quality cables, either flat or round :bigsmile:
