It's point-to-point 10w or less though?

Nope! Only use PoE from the switch to the hard drives, use the switch power supply to power the hard drives.
PoE switch prices haven't fallen very much.... Managed switch have barely moved in price in the last 5 years!

If you have a file server, you still could only have one PSU... many switches are 12v or 5v. An ATX PSU would be more efficient that a power brick. Larger PoE switches have their own internal PSU but they will still cost more than a simple server build.

While you have fewer failure points.... you have one single point of failure now: the PoE switch.

PoE is not really that useful for same box systems....

This actually shouldn't be that hard to implement. Just encodes Data over ethernet to SATA and vice versa. But what about RAID? thinking.gif Would I still need a pricey NAS?

Still don't trust seagate.
Very unreliable.

It's actually more complex that that though....

They have to abstract the SATA protocol... add security... ensure point-to-point HDD... controller support... API design/implementation. It's the details that will kill you.

Except they are as reliable as the other two HDD companies within a few percentage points.

Interesting, still I wonder about speed, even with a Gigabit router, that is going to be way slower than SATA 3 (6 Gbit/sec) and soon SATA 3.2 (or SATA Express) which is 16 Gbit/sec. I mean we are talking slower than even the massively outdated SATA 1.0 (1.5 Gbit/sec).

Or am I just missing something so obvious I'm going to feel like an idiot when someone points it out ... speed wise?

No, they're not. They had a bad run of drives...Just like WD has had, just like Samsung has had, just like IBM/Hitachi had. The recent Seagate drives I've owned have been some of the best drives I've ever had, and I've still got 3 7200.7 80GB IDE drives from about 2004 that work perfectly.
My WD Black is also great, however it's not worth the price premium over the Seagate drives (Similar speed, much louder and more expensive) IMO unless of course, the 5 year warranty comes into play.

While true, I think Seagate has had the worst luck in terms of having bad product lines.

WD Blacks are tanks though, Reason why I have 3. Though they are around 4-5 years old now. tongue.gif
Still solid as ever

1GbE is good for around 120B/s. The best consumer HDDs peak at around 200MB/s sequential. Note the italics.... most disk operations are more random and over the average.
