Re: Is the eSATA in the T510 powered or non-powered?

[ Edited ]

I use the eSATA port on my T510 to connect a Vantec NexStar 3.5-in external drive.  The eSATA port cannot provide the power it needs, so it has its own. It might be able to support a 2.5-in drive with an added USB port via Y cable. 

 

As for a 4 pin Firewire, it is there to connect a digital camera which has its own power - nothing more.

 

And, I also have a eSATA (2 ports) PCExpress card that can be used, and it is powered, but not sufficient for a 3.5-in HDD.  2.5-in OK.

FYI,

 

There are two types of eSATA ports on ThinkPad notebooks.  Standard eSATA and eSATAp.  eSATAp is known as a combo port because it is designed to also be a USB port.

 

eSATAp cables do exist.  I have one.  It allows you to take a standard 2.5" SSD or HDD and connect it directly to the cable without the need for an enclosure and power supply.  This is accomplished via the sides of the USB connection in the eSATAp port on the ThinkPad. The real beauty is you get full SATA speeds.

 

See http://en.wikipedia.org/wiki/ESATAp

 

See http://www.newegg.com/Product/Product.aspx?Item=N82E16812270245 for the cable I bought.  The maker URL is http://www.byteccusa.com/product/SATA/USATA-136/USATA-136.htm.

  • Interesting!  My T510 port is the combo one.  This cable looks interesting for the direct HDD connection sans case.
