What about reading several large media files concurrently?

Why? Personally, I can only watch one TV show at a time...

Sure, but if you're making a TV show or the like, it's not unusual to be compositing multiple video streams. TV companies have massively expensive hardware for this of course, but this will be a real boon for anyone who makes a living with multimedia.

I have an OCZ SSD in my desktop machine and I can agree with you, the biggest noticeable difference to me is in moving and deleting large files. I can't remember the last time I had to wait on a file to do the whole moving/copying/deleting dialog.

I almost grabbed an OCZ, but I'd seen enough reports in their forum of odd problems with Macs that I decided to stick with the Intel. When I bought the G2, it was reasonably competitive with the other drives - I think the pricing on competitive drives has come down quite a bit since then, but the G2 is fast and stable - I have no complaints.

I hear ya, and yeah I've seen the issues related to the Macs on the forums, though I think they've come a long ways in the recent months.

On that note, the OCZ forums are awesome, that company deserves heaps of praise for it's communication with the community. Developers are constantly releasing beta firmware and pre-release (fresh builds) there.

If shopping for an SSD at least consider the OCZ Vertex. I've been running one in my Santa Rosa MBP for 7 months with no issues and excellent performance. See ( http://blog.gtuhl.com/2009/03/26/ocz-vertex-ssd-in-a-17-sant... ) for install and before/after xbench runs.

I have an OCZ Vertex in my MBP. Great performance, but has definitely gotten slower over time. The folks at OCZ have just released the non-beta 1.4 firmware release that has better garbage collection.

The day I got my 15" MacBook Pro it was obvious the hard drive is what was limiting the performance. I have done a lot of experimenting with RAM disks since I have it maxed out at 4GB. For example, intense BitTorrent downloading (and uploading) on a RAM disk frees my hard disk from the constant reads and writes so I can have high speed downloads (and verification of d/led data) and still do disk intensive activities…

Don't use RAM disks -- it's not 1987, you have a grownup operating system with VM and everything.

As long as you have atimes disabled, the only thing RAM disks will speed up is writes -- recent FS operations are cached in memory automatically (and never paged to disk), so reading a 'warm' file doesn't hit the disk at all.

If you really need such a thing, tmpfs is vastly superior -- it operates directly at the VM page level, instead of idiotically mallocing a ton of address space up front (though I don't think anything like it is available for OS X).

Those complaints about the cost are hilarious. Either the person making them is a kid, or they have no "on-board" memory between their ears at all. The first 5 Gig HD I bought was a cheapo Maxtor at Staples and it set me back $500 about 10 years ago.

...how is this relevant to the fact that filling a server with SSDs is still much more expensive than with conventional HDs?

Because you can expect that cost to plummet substantially in a fairly short timeframe, based on past history. Bang for the buck on storage media improves by about an order of magnitude every 5 years.

If you'd like to see exactly how a macbook pro with an Intel X25-M feels like, I made a video to give you an idea: http://vimeo.com/7057850

A similar video with a OCZ Vertex SSD.

Executive summary: it doesn't have to be an Intel drive, just stay away from drives based on those old JMicron chipsets.

Ok, so what idiom should I use instead? I can't think of anything. Is this the market-economics version of political correctness?

The phrase you're looking for is "market clearing price" or just "market price". See also Obama's elementary explanation of why lowering gas taxes doesn't lower gas prices when gas is in limited supply: the market clearing price is still the price at which the amount of gas that people want at that price equals the supply of gas. Setting the price lower than this will result in shortages. It doesn't matter whether ga…

The phrase you're looking for is "market clearing price" or just "market price".

Those are definitely not the phrases I'm looking for. They don't contain enough information. I hope I can unwrap this without being too confusing.

First, you're preaching to the choir here. I'm pro-market-prices. I don't think there's anything unfair about the practice of price gouging. I support it 100%.

The issue here is you, and the others, aren't playing Gordon Gekko: "Gouging is good". You're playing Margaret "society doesn't exist" Thatcher: "When supply is constrained then prices go up. That's just the market at work. There isn't even such a thing a price gouging. Stop hallucinating."

Do I really need to spell out why and how it's different than a market-fluctuation? I got into it a little bit in a neighboring message, but I didn't go into the manufacturer/retailer dynamic. I think just the fact that it makes so many people irrationally angry is evidence enough that there's something unique about it.

Thought experiment: if gas prices doubled overnight would anyone get upset at gas station owners? Exactly. That's why it's not price gouging.

All I'm doing is defending the concept's existence and saying that because it exists I need a way to refer to it. If "gouging" is too pejorative then give me another word that actually captures all the relevant non-value-judgement-related meaning and is not just a sleight of hand attempt to pretend there's no there there. Because there is.

Just say the price went up due to unexpectedly high demand. I did say that. The issue is that I need 2 names: a name for the stores charging $450 (and are out of stock) and another name for the stores charging $600+. I chose "gouging" and "non-gouging". Concise, and everyone who read it understood what I meant to say. I'm not seeing any real alternatives being offered, except to replace clear, concise, universally un…

> I chose "gouging" and "non-gouging". Why the nice name for a supplier who doesn't, you know, supply? Discount camera stores are infamous for advertising things at great prices to get you in the store but being out of stock. It's a crappy way to do biz and should have a crappy name; "non-gouging" doesn't qualify.

Again with the criticize-without-offering-alternative.

Right, that's called bait and switch. No relation to price gouging.

using "price gouging" adds nothing to the statement that prices are high except a sense of outrage Of course it does. It says: 1. the subject is a retail product with a standard price , as opposed to a market product where the price is determined by bids and asks. 2. the price is temporarily higher than the standard price due to some sort of unforeseen disruption . 3. the price will return to the standard price when…

Not to get into a prescriptivism debate but "Price gouging" has a specific meaning, not just "charging a lot of money": > Price gouging is a term for a seller pricing much higher than is considered reasonable or fair. or > pricing above the market price when no alternative retailer is available

Not to get into a prescriptivism debate but "Price gouging" has a specific meaning, not just "charging a lot of money"

That's my point, actually.

Price gouging is a term for a seller pricing much higher than is considered reasonable or fair.

I'm only interested in the non-value-judgement related meaning. "Reasonable" and "fair" are meaningless.

What other people are saying is "you can't use that word because it's loaded with value judgement." I'm saying "OK, give me an alternative that captures the meaning without the value judgement. And is concise, clear, expressive, and widely understood."

pricing above the market price when no alternative retailer is available

This, also, is meaningless.

Something's not price gouging when people get upset? Or maybe you weren't paying any attention to sentiment when gas prices were soaring a few years back? People hated gas station owners, and there certainly were accusations of "gouging".
