What about reading several large media files concurrently?

That will be translated into a few sequential reads by the os & NCQ. No non-raid device gets any kind of speed boosts from concurrent reads -- ssd's just don't suffer as much from them.

SSDs are in a RAID0-like setup internally as it is.

The first generation of the Intel SSD's contained halogens so Apple couldn't use them. The new ones are halogen-free, so it might be they show up in future revisions of the MBP.

That's retarded. Stop kissing up to Greenpeace and give me my SSD, Apple. :(

Yeah, really! They should provide options to ship with the best SSD options available, even if it has to come at a premium price.

They need to let the market decide.

If you only access large media files (due to the very nature of media files, you want to read them sequentially from the beginning to the end) and your hard drive is not too fragmented, it is a reasonable assumption that you will mostly access the hard drive sequentially. However, if you need a large hard drive for a database and not as a media storage, obviously random access is just as important as sequential acces…

Why?

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

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 in other applications.

I can't wait for the day where my mass storage can have that kind of speed! (and it looks like it's closer than ever now)

Jeff Atwood is wrong on the internet... again! Tell me you're surprised. There are too many mistakes in the post to bother correcting. Just read the anandtech.com article if you want accurate info. For accurate price info you should know that the second generation 160 GB X-25Ms originally listed for $450 but shot up in price due to excessive demand. It's only in stock at stores that price gouge and MIA everywhere els…

The term "price gouge" is counterproductively pejorative. Being able to get it for some price is an improvement over not being able to get it at all, which, as you point out, is the alternative.

Ok, so what idiom should I use instead? I can't think of anything.

Is this the market-economics version of political correctness?

Why the downvote? What's wrong with the idea of giving consumers a choice on how 'green' they want to be? [Don't get me started on the whole 'green' bullshit.]

There are too many mistakes in the post to bother correcting. For those of us not as current on SSDs as you are, actually correcting his mistakes might be useful.

I learned everything I know from Anand:

In other, somewhat related, news - has anyone noticed there are 256GB usb sticks around (namely, Kingston has one)? Sure, they are expensive - but come on, 256GB! I wonder what are read/write speeds of those monsters. I have 16GB stick and it takes a mini eternity to copy stuff onto it.
