i own an asus m2n68-am se2 motherboard which only has 2 sata ports.
other than buying a new motherboard, are there other options to add more sata ports onto my motherboard?
the mobo has two sata's and have mounted sata hdd, sata opt.drive and front panel esata.
i haven't utilized the esata on the front panel cuz there are no more free ports on the mobo.
in case i wanted to add another sata hdd, will be impossible.
a PCI-SATA drive would perform no better than PATA because PCIs current maximum bandwidth is 133MB/s which is equal to the top PATA speed but with worse latencies and additional overhead.
I do see it is your only choice to get more SATA ports besides replacing your rig but do consider the speed impact PCI will have over even SATA 150.
If possible I suggest a USB 3.0/2.x to SATA adapter so it would be useful for a longer time to come than a PCI card. They can be cheap enough and even USB 2.0 would be faster than a hard drive, SATA or PATA, connected through PCI.
