OMG! Whose warped imagination came up with that! ;-)

Do a search of his postings and you'll see. All over Usenet, when the
issues alluded to above come around, he's there to preach.

Yep. Saw him here, then a couple of months later he popped into a local
(Huntsville, Alabama) newsgroup with the same messages. You forgot the
word "gr0und" BTW.

Well, that's his thing. Usually that word is absent in the original post
and he pops in to provide it.

Would this guy be an advocate of whole-house ummm, s***e pr0tection, by any
chance? If so, I think I remember him from about 3-5 years ago...wow.

The same.

But in all honesty, I am also a fan of "whole house s***e pr0tection", and
agree with him, at least on a technical level, that it is the way to go.

But, I'm no where near being in his league of fanaticism.

Yeah, that about sums it up. Like, "ok guy, we beleive you, but calm down!"
:-P

What mystified me was when he branched off into whole other levels of
topics he clearly did not have an understanding of. The odd thing was
that his central tenet wasn't wrong (though over the top), but he
presented it so wacky!

I added Light*ing protection AND WHSP when the house down the street was
burned down by a strike. North Texas is higlhy susceptible to mass
strikes and I had just bought my house months before. $3500 well spent.

There's a reason it's a "hybrid" drive. Flash memory ain't quite up to
the task on it's own yet. One day . . . .

It will also only work in a notebook, where performance is usually traded
for speed. Flash memory that handles current performance hard drive
transfer speeds (20-40MB/sec) is *expensive*, and there is nothing that
can match the 40-60MB/sec of high-performance drives.

The new "perpindicular" HD's sound interesting though. Expect sizes
well above 500 GB next year.

But we *still* won't be able to use them in our TiVos. Unless TiVo makes
some massive changes to the MFS file system, the 300-350GB range is the
most it can handle on a single drive.

No question. This is definitely "future-tech" as far as very
cost-sensitive applications go.

Really? What is the limiting factorin the MFS file system? I know the
LBA48 addressing scales up a lot.

Flash memory may be only 20-40 MB/sec, but it absolutely kills hard drives in
random access response time. If the flash section can provide data just long
enough for the hard drive to finish seeking, overall performance goes way up.

It doesn't help the constant large transfer scenario of a Tivo, but most
general purpose hard drive activity can benefit.
