Did you say that the DVRs have 2 controllers?Discrete for different jobs?Why 2?
Well, there are a few: incompatibility in negotiation protocol; support only lower speed (1.5 Gbps) - check the particular chip's spec; additional cost, additional signal's processing what is totally unnecessary in case of connecting SATA drive to eSATA connector on your DVR; the additional component's heating; decrease reliability as there are more components;etc ...
Usually two SATA as integral part om main chip (7038/7401 or 7400).
I think there is probably one controller chip that is capable of controlling two SATA channels, which is typical for SATA controller.
So we're talking about a hypothetical issue caused by unnecessary/redundant components? I thought it was the HR's internal controller that was limited to 1.5?
I was just thinking about this and I think I answered my own question about whether there's a controller in the dock - for a dock to offer ESATA and USB(which they all seem to), I think it would be a requirement for the dock to include a ESATA controller, because if it was just a simple ESATA pass-through there would be no mechanism for the USB interface to access the drive.
There you GO!!! A logical conclusion that everyone can understand. Thanx.
I'd pointed a few times - there is no separate SATA controller(s) chip inside of HR2x.
No such requirement for eSATA boxes.
So you are saying that there are 2 SATA controllers that are an integral part of the main chip,rather than separate, in an HR2x DVR.If that's the case,does the controller in an eSATA enclosure function when hooked to an HR2X?
Yes, it is functioning inside of the enclosure while it's totally unnecessary if you connecting it to DVR thru eSATA.
Received the TT BlacX and WD20EVDS today.
Had it up and running in 15 minutes (that includes the reboot time for the HR24, drive format, info download, customizing my favorites settings, and resetting up all my series recordings.)
So far, it's running like a perfectly calibrated Swiss watch!
Sincere thanks to everyone who assisted me.

Ah. Another happy customer.
I think you should start receiving royalties from your happy customers!
I would questioning who is first post a proposal to use BlacX ? ...
My wife would just spend it. I can't keep up with her no matter how I try. Now she's planning a party with vendors such as Tupperware and that ilk. So I end up painting and cleaning and so far she's spent close to two grand on this party. Hope no one shows up.
Be nice if Thermaltake would send me another docking station. She couldn't spend that. :lol:
Well, you know how to do searches on the forum, right? Take your own advice and search for an answer. I think I know.
Sure, why not ?

Huh. Had no idea these things had been around that long. Makes you wonder if there is something better out there.
Those of you using the Thermaltake BlacX eSATA USB Docking Station with the WD 2TB WD20EVDS, would you update the thread on how this is working out for you? I'm going to order a drive and enclosure/docking station very soon.
The Thermaltake docking station would seem to be an ideal solution to heat problems since a lot of the drive is not enclosed. Of course that also worries me since it is exposed.
Not exactly your question but I thought I'd shared "generic" docking station results. I use an Antec enclosure on one DVR (bedroom) and a docking station from Monoprice on the other (living room). The docking station is compact and simple, however there is little noise insulation, especially when placed on a shelf of a cabinet with an open area below (can you say resonance chamber?) I've used old mouse pads to provide a sound/vibration break beneath the dock and that is acceptable in my application. You will hear the drive activity if you listen for it. Like I said, it's fine in my application but YMMV
I've got three TTs and they all work quietly, without vibration. As I write this, I have a TT with a 1.5TB Seagate attached to a 20-700, both sitting on a wooden shelf about two feet from my head, and I can't hear anything from the docking station at all. The day before the last NR hit, I did hear some noises from another TT docking station attached to a 24-200 with a 2TB EVDS HDD in it. Since the NR, it has been quite quiet. My third TT is on a glass shelf attached to a 24-500 and I've never heard a peep from it.
In short, I'm quite happy with the TT docking stations. I've never tried another brand of docking station. I've had a few MX-1s and did have some sound issues and had one that just didn't work. At the time I bought them, the MX-1s were the best enclosures we could find and I had no idea what a docking station was. My opinion has changed. I prefer the TT docking stations.
About the HDD being exposed, apparently no live parts are exposed and there's very little danger of knocking them over, they're quite stable.
If you want a recommendation about an HDD, I'd recommend the WD EVDS series. Don't get an EARS. The EVDS runs cooler than the Seagates and are quieter.
Thanks to both of you for you comments. I am getting the 2 TB WD20EVDS and the Thermaltake BlacX eSATA USB Docking Station. I'll be using the thread that intructs how to copy data from one drive to another. Wish me luck.
