been looking at hard drives and have seen most people recommend the seagate sata 2, however i am having trouble finding the sata 2, yet there are plenty of sata harddrives, is there much/any difference?
Cheers |

Theoretically, twice the throughput speed... 1.5 vs 3.0 Gbits/sec.
First-generation SATA interfaces, also known as SATA/150 or SATA 1, run at 1.5 gigabits per second (Gbit/s). Serial ATA uses 8B/10B encoding at the physical layer. This encoding scheme has an efficiency of 80%, resulting in an actual data transfer rate of 1.2 Gbit/s, or 150 megabytes per second (MB/s). The relative simplicity of a serial link and the use of LVDS allow both the use of longer drive cables and an easier transition path to higher speeds.
Soon after SATA's introduction, enhancements were made to the standard. A 3 Gb/s signalling rate was added to the PHY layer, offering up to twice the data throughput. To ensure seamless backward compatibility between older SATA and the newer faster SATA 3.0 Gb/s devices, the latter devices are required to support the original 1.5 Gb/s rate. In practice, some older SATA systems that do not support SATA speed negotiation require the peripheral drive's speed be manually hardlimited to 150 MB/s with the use of a jumper for a 300 MB/s drive. [1]
Like SATA 1.5 Gb/s, SATA 3.0 Gb/s uses 8B/10B encoding resulting in an actual data transfer rate of 2.4 Gb/s, or 300 MB/s.

I've got one of those Seagate Barracuda 7200.10's and they're great drives.
Highly recommended.
jae. |

So there's no benefit of having an SATA 3.0 (SATA II) vs an SATA 1.5 (SATA I)??
Also, is SATA II available in Korea? |

yes..there is. You get double the speed.
Yes. a nice 240Gig Seagate will run you about 85,000WON. Sata2 3gb/s |

320 gb seagate sata 2 in at yongsan for 95,000 won. a geforce 6800xt for 80,000 won ok deal or did i get ribbed. i was thinking of having a go installing myself, but i opened the side took one look and thought NO. any idea how much it should cost to get installed?
by the way cubanlord you are bloody amazing

What do you mean by that? lol. 
Anyways, many people go out and buy these monster video cards (as I did once before). Upon opening the case, they realize that the case is too small and there is no room. LOL. Ah, my first time installing a video card, I'll never forget. Ok...back to the topic...
It really isn't that hard. The 6800GT (I think that is what you meant by xt?) is a monster card (great card too! I have one in my wife's PC). You'll need a lot of room and an extra 6-pin power supply cable for the card. If the 6800GT (XT) is PCI-E, then make sure your motherboard has a PCI-E slot. If the card is an AGP card, make sure you have an AGP slot.
Then, just plug it in, screw it in place with the one screw that'll hold it to the casing, plug the power supply into the back of the card (make sure your power supply is at least 350watts for that card), finally turning the PC on.
Go to nvidia.com and download the latest drivers; install them then BAM! Your baby works.
That is a very good price for that card (especially if new).  |
