    I'm really confused about all the new hard drive connection types. As far as i can tell, IDE and ATA are the same, and EIDE is IDE with a differing data transfer format. And SATA is the on with the small cable.

    Do all of these types of disks work in RAID configs? Some say only IDE, while ive also read that SATA and be RAIDed
    If its not in Family Guy its not worth it.

    IDE is the 80-pin ribbon connection used for most drives (40-pin for older or slower devices). It is the same as PATA (Parallel ATA).

    SATA (Serial ATA) is the new hard drive standard. It is faster at 150 Mb/s max versus IDE's 133 Mb/sec, uses far more manageable thin cables with only a few pins, and is commonly used in new motherboards for RAID.

    RAID is not a connection but a technology that involves linking two or more drives together to form an array. RAID 0 allows for faster speeds, but if one of the drive fails, all your data is lost. RAID 1 is for redundancy, so if one drive fails, you simply replace it and it rebuilds itself. There are more permutations as well.

    If you are getting a new motherboard, get one that supports SATA. If you already have support for SATA, only get SATA drives for future compatibility.

    Also, the current version of SATA is v1. v2 will be 300 Mb/s, v3 will be 600 Mb/s.

    RAID can be used with any type of drive. A few years ago RAID was almost limited to high perfomance SCSI drives. But back when the newer processors and motherboards came out, they started offering RAID. Some (I'm hesitant to say most) of the newer Intel boards come with some sort of SATA RAID.

    You can do RAID with IDE, EIDE, ATA, SATA whatever... you just have to find a card or motherboard that can do it. I would recommend you not doing RAID unless you have SATA. This is simply because the performance would not be very good with slower IDE drives (in some cases it can seriously bog down the performance of the computer).

    RAID stands for Redundant Array of Independant Disks. The most common types of RAID are RAID 0, and RAID 1.

    RAID 0 is not a true RAID, since it offers no redundancy. RAID 0 requires a minimum of 2 drives. RAID 0 is based on performance. It stripes data across the two or more disks. So you can write and read things twice as fast (theoretically).

    RAID 1 offers the highest protection of data, because whatever is written to one drive gets written to the other. This way if the primary drive fails, all you have to do is replace it, run a few configuration programs, and you are back up and running, without any data loss. RAID 1 needs a minimum of 2 disks.

    Both of these can be run with more disks. There are also other types of RAID offering various types of redundancy. But all of these require more than 2 drives. It is also imoportant to mention that whenever you do RAID that all of the drives must be the same size. Like an 80 and a 40 GB drive in RAID 1 would not work. This is a good website, with lots of visual examples too. http://www.acnc.com/04_01_00.html

    Very cool, thanks for all the good info. I decided to buy an ASUS mobo with build in sata raid, and eventually im going to get some Wester Digital sata drives, but for now im strapped for cash. :ermm:
