Summary: I own two of these, version 2.1 and version 3.0. Version 2.1 definitely runs too hot but after 2 years of being on 24/7 it is still going strong. Version 3.0 runs cooler and the performance on both is outstanding.
Summary: This excellent Ethernet Switch fully lives up to any expectations related to its prestigious manufacturer. Metal body: heavy, solid, durable-looking. Setup time: zero. Problems/bugs: zero. All three PCs having Gigabit capability in my home network immediately recognized the new 1GB bandwidth limit.
Summary: Version v3 fixes the well known problems of v1 - noisy fan, no jumbo frame support. Also fixes v2.X issue of overheating. The SD2008 has gotten some justifiably bad reviews based on the earlier v1 & v2.x designs.
Summary: For a low cost switch this one works extremely well and is built very solidly. With the 10/100/1000 speed capability you can backup from one machine to the other (assuming you're running gig Ethernet NICs in the PCs), performance is great.
Summary: You can rely on Cisco. Once I plugged it in, it's been working like a charm. It does its job and that's all there is to it. This is not a complicated device; it's there to allow fast speed connection between your Gigabit Ethernet ports on your computers. And it does it well.
Summary: I guess some of the earlier versions of this switch had heat and noise issues. I bought mine in March 2009 and it's been working flawlessly. No noise at all and the case is barely warm to the touch. Just plug in the power supply and CAT5E cables and away you go! No brainer simple.
Summary: Signifiant changes have occurred over the life of this switch. Version 1 had an internal fan and was quite noisy, albeit cool running. Version 2 & 2.1 eliminated the fan. However capacitor C251, sitting next to an internal heatsink is prone to failure after 6 - 8 months, resulting in dropped packets...
Summary: Cisco should give this a new product code because the existing reviews are for the earlier model and they have fixed the problems. The model I received is fanless and works just fine. I have not had opportunity to check out the speed, but it seems to work just great.
Summary: I received the latest v3 revision of the Linksys SD2008 8-port Gigabit switch, it has no fan, therefore no fan noise, it's dead quiet. Other than the lights, you'd never know the thing was even powered on.
