Actually, "client" workloads (personal computers) aren't very parallel so the requests are served sequentially. As such, this won't help too much.

Most client machines don't have multiple drives mirrored either. I was thinking purely in a server setting when I made the comments, though I'll admit that I didn't specify.

A HD with two head systems still wouldn't match an SSD for random reads, but it'd be much better than one. Depending on the use it's seeing, it could even employ different algorithms depending on the use mode it's seeing to help speed things along. In addition, more cache might help it during a large sequential read, allowing the heads to leapfrog each other better. Like I said - engineering and programming nightmare, but an interesting thought experiment.

By the way, if I remember correctly multiple requests on flight were implemented on SATA standard for client drives, 10 years ago or so on (SCSI had them for quite a while). I'm not sure Windows XP uses these queues.

You're talking about how the system queues multiple data(read/write) requests with the drive, and the drive possibly delivering them out of order(because it's using an optimized path to collect all the data), right?

I assumed that capability from the start. The REAL trick to the system is that to date it's one read head per platter, thus one device serving all the data. With two head systems, the question comes up of how you optimally assign said demands between the two head systems to most efficiently move the data.

This is actually a very interesting proposal. While I imagine the engineering and programming would be a relative nightmare*, it would provide a number of options for hard drives.

While it wouldn't double performance in most cases, especially not sequential operations, for random operations it'd be almost as good as two drives. Maybe better if the access is typically really random and one head can 'field' mostly the outer disc calls while the other catches the inner disk ones.

*Just look at the difference between programming a single thread application and multi-threading!

One thing that isn't obvious though is that it's a 30Hz monitor. All the 60Hz ones, as far as I can tell, are still in $1000+ territory.

I should probably have put some disclaimers in my post about affordability and suitability. I'm not a refresh snob but I can't help but think that 30Hz is a bit slow for gaming, perhaps even video watching.

Long live Byte. Goodbye, Byte, Circuit Cellar, Pournelle, and so many other characters. Long live Ars Technica, Wired, GigaOm, and dozens of other sites like NetworkWorld, InfoWorld, The Register, and so forth. Print will never come back. You won't feel it in your hands until your foldable smartphone makes this comfy some day in the future-- to do again.

I loved reading Byte! starting from the beginning. Reading what hardware and software hackers, who followed hacker ethics not the criminals called hackers in the press today, were doing was terrific. My two favorite columns were Steve Ciarcia's Circuit Cellar, which is now a compleat magazine of it's own, and Jerry Pournelle's Chaos Manor.

His antipathy towards our most important civil right, the right to self defense, shows that Stevens was never fit to be admitted to the bar at all. The second amendment doesn't need fixing, it needs ENFORCEMENT.

The right to keep and bear arms isn't for the government to grant or withhold, and the second amendment doesn't even presume to do so. It acknowledges the right as pre-existing, it cites one important reason for preserving it, and forbids the government from infringing it.

The sick fuck principal and the sick fuck vice-principal at my middle school just loved to paddle kids until their asses were purple.

Never encountered that in school, but by 9th grade I already knew what kind of damage you could do to someone if you knew their name, address and SSN.

As children most cops and most judges were the bullies. For that matter, so were a lot of school administrators. They don't understand the problem, or that there even is a problem. I was suspended for finally hitting back in junior high school, and almost expelled when I did it a second time.

Do you have data to prove that? If so share it.

And, what if this kid commits a Columbine-esque revenge scenario?

Appropriately, the page with TFA has an ad encouraging me to "Win an AR-15 from Sebastian Ammo". Google is getting scary...

I have the same ad, and it's not from Google. The link is to another page on the same site. Now that page does have a Google ad, about slimming fat wallets.

As for the action taken by the school, one really has to wonder as to what kind of cretins make up the school administration. And what they could possibly have hoped to achieve by filing charges, other than a nasty (and well deserved) publicity backlash? Although for a society run by lawyers, that's perhaps what one would expect. Squeaky wheel gets a beating, and a teenager gets hauled in front of a judge on charges of "disorderly conduct" in a school. Seriously... Can any of the officials involved in this case look in the mirror and tell themselves that they are doing the Right Thing?

Agreed.
