eSATA (external SATA)
There seems to be some confusion in the NGs about eSATA.
The most prominant features of eSATA are the longer cable length (up to 2 meters), the cable's shielding, and the plug to accomodate the shielding. eSATA can be used with external adapters for both desktop PCs and laptops, and external enclosures are available that have their own power modules and cooling fans. Here are some links to representative info: Silicon Image white paper on eSATA: https://www.sata-io.org/docs/Externa...WP%2011-09.pdf SIIG product offerrings in eSATA: http://siig.com/productlist.asp?catid=80 SIIG PCIe/eSATA card: http://siig.com/product.asp?catid=7&pid=1018 eSATA back panel adapter brackets: http://www.firewire-1394.com/externa...-solutions.htm eSATA cables: http://www.firewire-1394.com/sata-cables-shielded.htm eSATA external enclosures by Kingwin: http://kingwin.com/jt35ebk.asp http://kingwin.com/jt35eubk.asp Use the model nos. and the usual search engines for current prices, i.e. NexTag.com, PriceWatch.com, PriceGrabber.com, Froogle.Google.com, etc. *TimDaniels* |

Because you're here, Rod. Here are some links to representative info: Representative, my ass. Your ass is irrelevent, Rod. Surely there is more than SIIG. Obviously you are spamming for SIIG. Very funny. Not so clever, though, Rod. eSATA back panel adapter brackets: http://www.firewire-1394.com/externa...-solutions.htm Well, those are obviously not eSATA. You have to extract your head and read the page, Rod. eSATA cables: http://www.firewire-1394.com/sata-cables-shielded.htm Of which only the last one is eSATA. Two of the three cable types involve eSATA, Rod. eSATA external enclosures by Kingwin: http://kingwin.com/jt35ebk.asp Unfortunately it doesn't say whether it has an eSATA to SATA bridge or not. "Interface: E-SATA Only" suggests that there is only an eSATA connector. Want to point us out to eSATA diskdrives? You are really dumb, Rod. *TimDaniels* |

Regular USB/Firewire enclosures require a bridge chip to translate between the interfaces. Since eSATA is native, I assume such a bridge chip would be needed? Is the only difference the connector? In which case the enclosure would just need a simple connection between the eSATA and SATA connector on the host/device side. Or, are there some other difference such as signalling level that need an IC to take care of? How is power usually supplied for 2.5" eSATA enclosures? I've seen some use USB power(probably a Y cable for more current) but since an unconfigured USB device can only draw 100mA, doesn't the enclosure have to enumerate before it gets the full 500mA? If so wouldn't another USB chip be needed? |

Regular USB/Firewire enclosures require a bridge chip to translate between the interfaces. Since eSATA is native, I assume such a bridge chip would be needed? Is the only difference the connector? According to the Silicon Image white paper on eSATA, the differences between SATA and eSATA a 1) the cable and its connectors, 2) the higher signal levels needed to accomodate the longer cable, and 3) the shielding and grounding requirements for the external enclosure and the hard disk drive. In which case the enclosure would just need a simple connection between the eSATA and SATA connector on the host/device side. Or, are there some other difference such as signalling level that need an IC to take care of? The white paper implies that with an eSATA cable of 1 meter or less, the SATA control chips should work. The brackets listed as "SATA Internal-to-External Bracket" should do the job in such a case: http://www.firewire-1394.com/externa...-solutions.htm The white paper also mentions SATA/eSATA signal level adapters on PCI cards for cable lengths up to 2 meters. These currently are made by SIIG and probably others. How is power usually supplied for 2.5" eSATA enclosures? As far as I can see, Kingwin doesn't make eSATA enclosures for 2.5" SATA hard drives. For 3.5" SATA hard drives, the Kingwin website lists a plug-in power "adapter", i.e. power supply module, for its eSATA enclosures. The eSATA enclosures for 3.5" hard drives are models: JT-35E-BK, JT-35EU-BK, KH-350SE-BK, and the KH-350SEU-BK. I've seen some use USB power(probably a Y cable for more current) but since an unconfigured USB device can only draw 100mA, doesn't the enclosure have to enumerate before it gets the full 500mA? If so wouldn't another USB chip be needed? I'd not use USB power for a 3.5" hard drive. I don't know about 2.5" hard drives powered by USB. For reliability of any external hard drive, I'd want a cooling fan and a dedicated power supply. *TimDaniels* |

Is the only difference the connector? According to the Silicon Image white paper on eSATA, the differences between SATA and eSATA a 1) the cable and its connectors, 2) the higher signal levels needed to accomodate the longer cable, and Right Timmy, so where are the drives with eSata signal drivers? 3) the shielding and grounding requirements for the external enclosure and the hard disk drive.

The eSATA enclosures for 3.5" hard drives are models: JT-35E-BK, JT-35EU-BK, KH-350SE-BK, and the KH-350SEU-BK. So Timmy, does it pay well to be a Kingwin shill? I've seen some use USB power(probably a Y cable for more current) but since an unconfigured USB device can only draw 100mA, doesn't the enclosure have to enumerate before it gets the full 500mA? If so wouldn't another USB chip be needed? I'd not use USB power for a 3.5" hard drive. No kidding: Like you could. I don't know about 2.5" hard drives powered by USB. There isn't much that you really know, is there, Timmy. Just some pretend loudmouth showoff kiddy. For reliability of any external hard drive, I'd want a cooling fan and a dedicated power supply. *TimDaniels* |

"Folkert Rienstra" , aks Rod Speed, croaked:
Right Timmy, so where are the drives with eSata signal drivers? So who needs 'em? You're too hung up on specs and published standards to move your bowels without a manual, Rod. *TimDaniels* |
