Re: What about Fractal Design Tesla PSU?

So how is this PSU?
I read here that the internally it's "almost" the same as Nexus NX-5000.
I'm considering getting it because it's the closest thing to my budget - exceeds it by almost 10 € already, but the second closest thing (said Nexus) is another 15...

Yes i've read up about partition alignment for use in XP however, none in the case of using Windows 2000.

A few months is more like it. If not less. There's a lot of space for improving bandwidth.

Yes, but when updating the firmware you lose all data. And if you get a bad 1199 IRC firmware when building a new PC, tough luck. So IMO the update must be done on a different machine, not a new build. Just make a partition image and store it temporarily on another drive. And most people know sb. w...

Depends on the controller, doesn't it?
I thought you would use an ordinary on-board SATA controller, with a max bandwith of 300 MB/sec. About the "unnecessary", I am sorry, that was a bit harsh indeed.
That's "theoretical 300 MB/s per drive", not for all drives together.

Power loss is not a problem. Vertex has a battery (or most likely:capacitor) that keeps memory for the time needed to write it to flash.
