How much faster are SATA hard drive than 'regular' hard drives. I imagine hard drive speed is demonstrated in the speed of opening applications and large files. Is this mostly where you see performance difference between the two? Thanks for all comments and help in advance. Patrice |

Refer to http://pcburn.com/article-Linux_SATA_vs_IDE_Performance-pg6.php As per this test, performance was not noticebaly good. |

These days, the interfaces on drives are much faster than the physical medium can provide to (or consume from) them. i.e: If the heads inside the drive can only handle 50megabit/s of data, it doesn't matter if the interface can do 100 or 150megabits, you'll still only get 50mb/s worth of data. Think of it as the equivalent of having an 8 lane superhighway with semi-trailer loads of data going back and forth, and then having to unload and have a horse drawn cart drag the data over a dirt path for the last mile. That being said, SATA (serial ATA) interfaces are capable of higher speeds than the older PATA (parallel ATA) models. However, interface speed is not the only metric, as platter size, number of platters, rotational speed, head seek time, cache, chipset, and chipset firmware all affect speeds. |

When it comes to speed, the difference between PATA (the old ones) and SATA is relatively small. However, SATA offer many other benefits like longer cables, hot-swappable drives (you can plug them in and out while the PC is on), they usually ship with large buffers (8 to 16MB) and many motherboards come with and SATA RAID controller by default which, if you have to very similar drives, can allow you to increase their aggregate speed (RAID-0) or help minimize data loss when one of them fails (RAID-1). Check out the Hitachi drives, they're usually the fastest :) |

There are two major versions of SATA. SATA 150 and SATA II, SATA 150 was the first version of SATA to come out, compaired to the performance to a IDE is almost neglible(IDE is 133 M/s SATA 150 is 150 M/s). If the Spindle speed on the SATA drive is however 10k RPM(WD Raptor SATA Drive), then it would be faster, and better performing. The newer SATA II has a data transfer rate of 300 M/s, allowing more data to be sent between the hardrive and system. However, speed of the spindle is still what affects performance in the long run. |

Let's not forget the bus bandwidth bottleneck as well. :) |

On a PRACTICAL basis, the difference in the interface apparently won't matter that much. I have some geek friends who were recently discussing that even using solid state hard drives, that Windows XP didn't load noticably faster. With the large cache sizes, and as the other folks have stated (marcbb-ga's explanation was a great analogy), so much of the speed impact being physical attributes of the disk (like rotational speed) -- you might be better off focusing on issues like warranty, reputation, user feedback, etc. when purchasing a drive. You need SATA, as I understand it, to set up a RAID setting -- but if you just want to use the hard drive stand-alone, then an IDE ATA drive with a big buffer and the best cost per gig, along with a good reputation, a long warranty, and good user feedback from a site like Newegg.com is going to be a very reasonable strategy for a typical Windows user. |

So the next question should be: What performance increases could you expect by using 2 SATA drives in a RAID 0 configuration? Let?s assume the drives are SATA I and those operate at 7200rpm. |
