Need a LP4 to SATA adapter or y-splitter?

[Vigo]

I have one direct SATA power line (and only one) coming from my psu to my single SATA drive but I plan on getting another SATA drive. The WD I have (and will buy since I'm going to set up a RAID configuration) has a regular atx psu connector as well as the SATA.

Should I just plug-in (it), the second, or both drives using the standard atx molex connector, or should I get a y-splitter (or adapter) to convert one of the atx molex connections into an SATA connector (or two) so both drives will be plugged in through the SATA power connector?

Whats the difference? I could understand a difference between the dedicated SATA line and the regular atx line... but why would I need to use an LP4 4 pin to SATA adapter, as opposed to just plugging the hard drive in through the LP4 connection on the back?

I don't even think theres a difference between the SATA and LP4 connections. Would using the LP4 connectors be exactly the same as using LP4 to SATA connectors (aside from appearance)?

the sata power connectors are differant for the pourpose of hot swapping.
you can use eather method you want to use.

You can use either connector - but not both! The only advantage to using the SATA connector is you can safely hotswap the drive.

Sounds good. Thanks.
