Think of a Port Multiplier as a USB hub.  It is possible to plug a Sata PM into a single host SATA port and a achieve up to a 1:15 relationship ie: 1 physical host SATA port supporting 15 SATA hard disks, hence my comment about the 1:1 relationship being a little misleading.

Please note that many SATA ports do NOT support SATA PM, and frankly the documentation of those that do is mostly extremely lacking.

In most instances there is no hub as such, the PM sits on the backplane of the SATA expansion chasis that you buy.

The goal of SATA PM was to provide easy, cost effective expansion of SATA storage.  The limit being, that the host port is still only 1.5/3Gb/s, so obviously it can be easily oversubscribed.  Given your application oversubscription may well not be an issue.

Doctor

This information is misleading with repect to SATA Port Multiplier.  Particularly where you make the statement one drive, one port.  More detailed explanation in the context of this questions is required.

For a goddam technical magazine, please get this sh*t straight.  What the hell does cell phone data standards have to do with WiFi - 802.11 standards!!!

ATTs upgrade plan will do nothing for you WiFi.

1. The AntiVirus review

This was interesting, but I feel that it didn't address one of the key issues of the current generation Maximum PC recommendation.  Specifically with Core i7 the benchmark on application has moved from 32 bit standard to 64 bit standard.  Which of these platforms provides a 100% functional native 64 bit Security Suite?

 2. The PDF quality

Can you please please please decrease the compression and increase the quality of the images you embed in the PDF file.  Currently many of them are have completely unreadable graphics.  The difference between a 8mb PDF or a 16mb PDF is lost in todays world.

thanks

Interesting that Micrsoft Research has been looking at this.

 In fact it is already a techniiqe in operation in Cisco's Telepresence teleconferencing suites.

Interesting thoughts.

 The challenge I see with a Universal/Open Wireless approach as the primary delivery vehicle is the different class of service that it offers to users.

 Looking down the road at the new class of services that are coming online on the internet - things like telepresence, two-way HDTV service, broadcast HD IPTV - they are all enormous consumers of bandwidth.  As the price of employee travel rises - this will be the type of service people will want at home.  For those of us with Cable or FTTH/N - not an issue.

When is any current wireless solution going to offer anything close to this level of bandwidth?  Anyone stuck at the other end of a wireless universal approach is going to be a second class citizen for a very long time.
