"Stick with your 10/100 switch and do not buy this!"
Pros
its 10/100/1000!
Cons
Super fast computers will be losing their mapped drives randomly.
Fast computer by that I mean for example: DELL 960 or better.
Slow computers seem not to have many issues with this switch as its within the time alloted to hand out an IP.
Summary
Do not buy this switch for mission critical objectives!
