  • Using multiple drives to optomize speed??

    I think I had read somewhere that installing the OS (Win XP in my case) on it's own drive could improve performance. I have two 36gb raptors that I would like to make use of, but they are kinda small to be everyday drives. However, I wondered if using these drives in a stipped array just for windows and using my two 200GB drives in a mirrored array as storage for mp3s, vids and images and stuff would be benificial. Basically, I'm really trying to fit these raptors into my install somehow.
    Its not the cards you're dealt, its how you play the hand!

    I been looking for that all over the net, but I can't find it.
    Please help.

    I think you want the opposite mate - mirrored raptors as your boot drive should boost performance and boot time, while I can't se any reasons for mirroring your 200gb's other than redundancy if one of them fails..

      36Gb isnt enough for your OS ???

      I have a 30Gb 2.5'' for my tinyXP + a 300Gb 3.5' for my data. I keep a backup of my data in my home PC since its the same music and video etc...So no need of RAID.

      I don't know if it would speed up the comp it self but it is definitly easier that way, cause your OS is alone on a disk and can be reimage without touchin the DATA. So make an image of the OS disk...in case(ghost or acronis).

      I Just reinstall my 30Gb last night from scratch with TinyXP. What a lovely XP version. Nothin useless, everything is ajust for best performance. I installed all the usefull apps, winamp, winrar, adobe reader, flash. Guess what...1,8GB hahah THATS NICE!!! and with the Boot.ini mods to fast the boot time IT takes 10-15 sec to get to WINDOWS....unbeleivable. Only missing RR, GPS apps etc.... + boot on my frontend, et voilą!

        if you wnat speed you should put your 2 raptors in raid 1. Making them 1 60 gig HD. raid 1 will put half ur data on each drive and should load from both drives at once. This will theoretically increase load speeds by 100%.

        Works pretty nicely imo

        If not go with a linux build and you will have alot faster boot times and a moe optimised system.

          No, RAID 1 is Mirrored RAID, two drives are combined into one "physical" volume which consists of identical data on both drives. Usable capacity should be the smallest drive in the mirrored RAID set. If one drive fails you will still retain the data on the other, and have the ability to rebuild the RAID onto another drive.

          RAID 0 is Striped RAID, this is the one that stores information on multiple drives allowing you to drastically increase read/write operation for the RAID volume. Usable capacity is the size of the smallest drive in the set multiplied by the number of drives in the set.

          Raptors are known to run really hot, its something you might want to think about when you're putting one (or more?) in a car pc..

            What about the power draw of all those hard drives? Do you have that covered?

                I run Raid 0 using two 150GB hitachi notebook drives, it does increase performance particularly boot time, cold boot to front end 30-40 seconds(also using minlogon). I need to experiment a bit with changing stripe size but been a little lazy to do so.

                I also ran my setup in non raid config boot time took nearly twice as long. Keep in mind running raid will also introduce its own unique issues

                  this is interesting i thought abou this as well, putting 2x 2.5 drives in raid 0, but i was thinking of looking for single disk low power and low heat 7200 drives.... does something like that exist

                    If you want a low power drive, you want a laptop drive (2.5 inch), plain ans simple. They make 7200rpm laptop drives.
                    Overall, hard drives don't put out a lot of heat compared to other PC components, namely CPU & 3D GPU. They are more likely to react to ambient heat than heat up themselves.

                      heat is one thing but power consumption is another i know that a lot of people are worried in laptops from 5400 going to 7200 hd

                      since most of carPC's have on board video then heat wont be too much of a factor and using a mobile or low power cpu as well, im using the x2 be2350 45w with a massive heat pipe heat sink that will be enouogh cooling for the whole car pc its a 120mm fan on it, its hte cnps8700 on a microATX board

                        What about those new solid state Drives (for just the OS and other boot components)??? there faster Read and Wright times... and BOOT ALOT FASTER!!!

                          of course but a 120+ gb hd is much cheaper then even a 8-16gb solid state HD and you want the new good and fast ones the sata(2) not the pata66 or whatever they were

                            A good solid state drive like the Mtron will boot faster then pretty much any sata drive's configured in raid 0 available.

                            I know I switched to a Mtron SSD and was previously using 2 sata drives in raid 0. Also the single drive is easier to config no experimenting with strip size

                              toms hardware had good stats, were regular HD's are faster and the "good" fast SSHD's are quite expensive and not worth it really in a car IMO, and at the end you still need a normal HD for your storage and data, but as SSHD's get cheaper im sure that will be the best solution to carPC's but atm its too expensive for 1 component, and you should probably invest in faster mobo/cpu/ram/video etc... before such expensive storage media
