they are all using SATA cable and power lines now
from what you are saying "四针电源" seems you are using IDE cables. Then you will need special adaptor.
There are many SATA=IDE or IDE=SATA modules sold for $2 on eBay.
If you are all using 扁平电缆, you are using SATA, there is no difference between 2.5"HDD, 2.5" SSD or 3.5" HDD.
