eSata vs USB 3 for external SSD

[tris179]

Hi,

I have been offered to change my laptop at work currently using a Dell 6330, and have been offered a Dell 7440, I love the form factor of these new machines, but it's missing eSata, which I currently use to connect an external SSD to use with workstation as I can also use it on my home machine.

I understand moving from eSata to USB3 for external connectivity could be slower, but is this something that will be greatly noticeable with using it just for VM's? I am more concerned with the loss of I/O rather than max throughput.

Any advice would be great?

Thanks

if your using windows 8 and have a USAP dock/enclosure and native intel usb3 port then go with usb3 if not esata

USB 3 throughput is pretty good, but in my experience the latency is higher than esata. This may impact the performance of your VMs, but then again might be offset to a degree by the low latency of the SSD.
