VMultra bundles USB hub, DVD drive, SD slot and 500GB HDD to form ultimate laptop peripheral — Engadget

My Comments

Previously, I have written some articles on the USB-connected expansion modules that can extend the functionality of those Ultrabooks and similar ultraportable computers. Here, I was

This included my reviewing a Sony VAIO Z Series premium ultraportable that was equipped with one of these modules that had an integrated slot-load Blu-Ray player.

But what amazes me about this particular VMultra expansion module is that it is effectively acting as a “storage hub” with an SD card reader, DVD burner and a 500Gb hard disk, thus adding at least three extra drive letters or disk icons to your computer. This also is effectively adding on an external hard disk to the computer for use in keeping “main office” work on the desk while you have “portable” work in the computer. Expect this unit to be equipped with a USB 3.0 host interface as well as a multi-port USB hub that most likely continuously self-powered so you can also charge those gadgets off it.

This could become the start of the expansion module that is more about a virtual system unit for an ultraportable, being equipped with onboard secondary storage, DisplayLink video functionality, audio functionality and the like to be kept as an “at home” or “at office” option.

I have covered the concept of expansion modules a.k.a docking stations that connect to laptops via USB 3.0, Thunderbolt or other similar connectivity as a must-have accessory. This is to allow people who use smaller or less-equipped laptops like Ultrabooks to use other equipment like optical drives or larger displays at their normal workspaces yet be able to maintain the portability of these machines. I cited this kind of device when I reviewed the Sony VAIO Z Series ultraportable which came with one of these modules that housed a slot-load Blu-Ray optical drive.

Lenovo issued one of these USB 3.0 modules as the ThinkPad USB 3.0 Dock. This unit had a Gigabit Ethernet connection as well as an external sound module and self-powered USB 3.0 hub for five devices.

Now ASUS have issued an improved USB 3.0 variant of a USB docking station that they previously released. The previous iteration had USB 2.0 connectivity therefore having access to 10/100 Ethernet, VGA and DVI video as well as an audio module and USB self-powered-hub connectivity for four devices. The video is supplied to the module using the DisplayLink video-over-USB technology to transfer the video to the VGA and DVI ports.

Now this improved version satisfies the current expectations by being equipped with a Gigabit Ethernet port as well as an HDMI port for current displays. This has the audio module and the USB 3.0 hub but uses the latest iteration of the DisplayLink technology to exploit the high throughput of USB 3.0 for high-resolution displays and stereo or surround-sound audio via HDMI. It is infact the first USB 3.0 docking station or expansion module that I have heard of that implements this DisplayLink setup.

Personally, I would like to see this device and the previous version equipped with an SP/DIF optical output using the same 3.5mm optical-electrical jack that Sony used with some of their CD Walkmans in the mid-90s to facilitate digital CD-MiniDisc recording with their MD Walkmans. Here this connection could be used provide a high-quality PCM stereo or bitstream surround digital signal to amplifiers that have built-in digital-analogue conversion circuitry.

As long as these are kept to common standards, it could then be feasible to supply the expansion modules to work with extra peripherals at one’s main work locations.

Lenovo now makes available a USB 3.0 desktop expansion module for your Ultrabook

Lenovo ThinkPad USB 3.0 dock lends its ports to your deprived laptop via DisplayLink, available May 15th for $180 — Engadget

My Comments

I have previously talked about on this site about the concept of standards-common expansion modules for use with laptops, especially Ultrabooks. These devices, also known as docking stations, would have connections for peripherals that you would typically used at your desk like larger displays, Ethernet network connections or work-specific peripherals.

Infoact one of these devices was part of an ultraportable laptop that I had reviewed, namely the Sony VAIO Z Series unit; and this one included a slot-load optical-disc drive that reads Blu-Ray Discs.

Now Lenovo have presented the ThinkPad USB 3.0 Dock, which connects to the host laptop using a USB 3.0 connection, already common on most laptops including higher-priced Ultrabooks. But it exploits the higher data throughput of USB 3.0 to allow for more than what one would typically expect from these devices.

For example, the expansion module is a network adaptor for Cat5 Gigabit Ethernet networks and an external sound module as well as a self-powered USB 3.0 hub for five peripherals. The self-powered USB hub also has the advantage of supplying power to USB peripherals independently of the host computer so that you could charge up smartphones and other gadgets or use it as a power supply for USB-driven gadgets.

But it uses DisplayLink technology to use the USB 3.0 connection to drive external displays while using the host computer’s graphics subsystem. This can encourage us to use the large displays with these laptops without needing to connecting them to the computer itself.

What I would like about this expansion module and any expansion modules designed along this line is that it isn’t dependent on the laptop being a Lenovo ThinkPad model at all, let alone a Lenovo unit. Compared to the Sony solution which exploited a proprietary “Light Path” setup over USB 3.0, this could be used with computers that use any USB 3.0 port.

This is more so as the next generation of Ultrabooks come with USB 3.0 ports integrated in to them but may have two or three of these ports as well as fewer connections for other wired peripherals. Infact the more of these devices that exist, the better it would be for people who use “work-home” laptops or 13” ultraportabls as travel/desk computers/
