[kwlug-disc] Multi-bay docks ... 1 at a time??? [Was: Re: Linux-compatible eSATA expansion cards]

[unsolicited]

How is the 'snappiness' of a desktop vm run off the dock vs internal drive?

For that speed (given that I see about the same time frames, myself, 
over my network) ... seems one may as well be copying over the network - 
'special' additional hardware purchase (e.g. dock/drive) not seeming to 
gain you much vis a vis tower / natively connected SATA III drive. And 
SATA express is here. [Granted, other advantages to your dock for your 
laptop - e.g. local backups.]

Really makes me wonder what it would do Sata / how significant the USB 
overhead is. And what an SSD would do.

In my wanderings I came across mentions of developer team development 
environment vms. Makes some amount of sense. Same reasoning lends the 
idea of one's 'desktop on a stick'. One's communications / PIM in one 
vm, development environment in another, etc. Hmmm. Institutes hardware 
redundancy yet returns to YAMTM (Yet Another Machine To Maintain) - if 
one has sufficiently fast hardware everywhere one might sit.

VNC might seem obvious, but screens size vary per desk (scrolling back 
and forth gets old really fast), and 'sound' isn't necessarily 
everywhere (if only for alert warbles). I gather this is why vbox 
'includes' rdp not rfb - rdp encapsulating sound, etc., while vnc does 
not. Hmmm. No wonder web apps / the cloud is becoming more and more 
popular. And tablets (portability). Or browsers with a few hundred tabs 
on the go. (-:
