article published on 18 August, 2008
The Serial ATA International Organization (SATA-IO) today released to its members the physical layer (PHY) portion for its third generation storage interface, which will be defined in the upcoming SATA Revision 3.0 specification. The new specification for the popular Serial ATA storage interface will double the maximum transfer speed from three to six gigabits per second (Gbps).

Problem..
All though serial ATA has it's advantages one of it's disadvantages is that if you computer came with a serial ATA card built into your motherboard like most hp dell and compaq computers do you cannot upgrade to the latest revisions of Serial ATA which makes you a loser in the long run they really need to make a Serial ATA card that is upgradable by a firmware update so users can take advantage of the new technology making it cheaper for users.

thats what PCI-PCI-e cards are for but......are HDDs themselfs keeping up with the new interface speeds?
when will see a jump from spinning mag drives to something more like Flash cards?

I don't see a problem necesarily. If the transfer speed is increased and the cost is relatively the same and it's backwards compatible with all older connections, what do you lose? I would start buying them knowing that if and when I do upgrade my mobo, I will have higher transfer speeds. Or maybe buy a cheap PCI-e card.

Most HP systems are upgradeable via a FW update. Go look at their website. You can find the FW under the "software and driver downloads" area of the site. Most of their embedded SATA controllers suck anyways, hardly any functionality what so ever.
anyways..
They don't even have any drives out right now that can read and write at those speeds, that I know of. Also, SAS has already been doing this for months now. I believe LSI has a controller that can handle all this I/O.

Not to mention a firmware upgrade won't do diddly if it is a physical limitation of the interface onboard. Firmware upgrades can help but if the components of the interface are not made to work with that spec then what do you expect from a firmware flash. I mean USB 1.1 and 2.0 (and eventually 3.0) all have the same port type but you cannot flash that to go faster because the hardware is different.

It's slow but it's happening. The new SSD's (Solid State Drives/flash based HDD) are slowly becoming more widely accessible. The problem is that they're way too expensive. $1000 for a 64GB SSD is the cheapest where I live.
Anyway, it's a good thing I'm still waiting until next summer to upgrade my whole computer. I'm expecting PCI-e 3.0, USB 3.0, and SATA 3.0 to all be standards in mobo's by next summer. By then it'll have been 5 years since I last upgraded, and damn will it feel fresh!

"flash" are as low as 350, so you are looking at 5-6$ a GB currently, still far from 150$ for 750GB, just looked up SSD...20ish$ a GB...ouchy!

Sorry but they are way too slow 100MB/s read and 80MB/s write for SSD and Zippy's flash card is even worst. Once they come up with the perfect super conductor that operates at room temps then we will see some progress. Don't hold your breat but they are working on it.

Love to see the new spec is getting finalized I suppose SAS is close too, great news for servers.

Mr-Movies
They are also insanely small GB wise compared to a HDD, both will have to triple twice and halve in price twice before it becomes something worth while as a HDD replacement.

FreqNasty, many of my computer's tasks are hard disk bound. My HDs are not as fast as the theroritical max but then they never are. I do suspect doubling the max speed will double the actual speeds of disks you buy.
Just because the disks use the same cables does not mean you will be able to run these disks on an older system by upgrading the BIOS. That would be nice since I just upgraded my system (mobo ect) but I am not that lucky.
