Comment Re:Our generation is lucky (Score 1) 183

I currently have a ~1.36 TB raid 5 array (4 x "500 GB" disks) because I ran out of space on the ~840 GB array (4 x "300 GB" disks). Unfortunately a flaw in the pci bus of that machine makes it incapable of taking a gigabit network card or a second raid card, so I had to copy the data over 100 mbps ethernet.

It wasn't a cheap upgrade, and the next one promises to be more expensive (when it becomes necessary), thanks to the fact that if the array exceeds 2 TB I'll need to buy a "64 bit" raid card.
Despite the fact that my current card advertises 48-bit LBA support, it doesn't actually seem to be capable of using more than 32-bits of that.

Mod parent informative. I would, but I'm out of points.

Many people don't understand power requirements, and if you're building your own pc you really should.

Also, if you get an 85% efficiency certified PSU, not only is that proof that it can actually manage its advertised output, but it is also at least 85% efficient at any power draw between 10% and 100% of its rating. High efficiency will save you a lot of money in the long run, and the build quality needed for that efficiency also means the PSU lasts much longer.

I have a 2.8GHz AMD dual-core, 4GB of ram, a GTX 285, three hdds and two optical drives in my pc. How big of a PSU do I need?

The same Tagan 480W PSU I've been using for ~ 5 years.

Just because your 500W psu didn't have enough power connectors doesn't mean 500W isn't enough. Just make sure you have one capable of sustaining its max output, instead of only being able to sustain half of what is on the box (and being able to do 1ms spikes of the power output they advertise). The 80% and 85% efficiency certifications are a great way to confirm this, as well as getting you an efficient PSU.

I can see PSU requirements being much higher for multiple graphics chips (the top end ones use 200W when going flat out), but do you really need multiple (for example) GTX 285s? I run all my games at max res, with HDR, AA, AF, and all the game's own options on max, and I can still put vsync on afterwards because the framerate's so high. And that's on one GTX 285.

There isn't one, really. I've heard good things about CFS.

An ideal SSD scheduler would need to perform read/write grouping, but only within the SSD blocks (with a read block and a write block being different sizes). Grouping across a block boundary is pointless for an SSD, you'd be better off letting the request at the top of the queue go. For a spinning disk, grouping is important all the time, thanks to it essentially being one continuous spiral track (close enough anyway).
