    Hitachi 7200rpm 80GB SATA II - 7K80

    Correct, this is the burst-troughput when readign from the drives cache - wihich does not make a very noticable difference to SATA1 or PATA in real-world situations.

    Hitachi 7200rpm 80GB SATA II - 7K80

    This is a question for me too - i have several 7k80 (PATA and SATA2) in use for server-applications that don't need much space and power. Although the overall-speed of the 7k80 seems not to be up to date. So what is the cheapest high-density one-platter-design ? The only SATA2-drives (should use the latest technology?) below 60 EURO in my region are : ~52 EURO Hitachi Deskstar 7K80 80GB SATA II (HDS728080PLA380) ~57 EURO Maxtor DiamondMax 10 80GB SATA II (6V080E0) ~58 EURO Samsung SpinPoint P80SD 80GB SATA II (HD080HJ) ~60 EURO Seagate Barracuda 7200.9 80GB SATA II (ST3808110AS) But which one is delivering the highest density, thus the most power
  3. nForce4 does RAID5 Anyway, why dont you run your fileserver with Ubuntu Breezy Server-Distribution ? This will provide you the incredible EVMS with Linux SoftRAID (Level 0,1,5,6) and LVM, perfect felxibility and decent performance at no cost

    400GB SATAs for a cheap RAID 5

    Recently on the fair "Systems" in Munich the storage-systems-manufacturer insured to me they have the best experiences with Hitachi and Seagate. Even though their latest products are equiped with WD YR

    I like this one the most, it fits all your needs - the legendary Cherry G80-3000 Available with soft, linear or klicky (IBM-like) pressure point and several different additional features and layouts. It's very very robust, will almost last for ever

    Nested Linux software RAID arrays

    WTF? Ubuntu is equiped with EVMS ? This is surprising for a Distribution aimed to desktop-usage. But this could be the way for you. The other Tool that is able to resize RAID5 is called "raidreconf" which should work almost as reliable than EVMS but without modification of the kernel so you can easily use a self-breed 2.6.13-kernel.

    If only ONE drive fails you have a degraded array - in other words : You have simply MORE drives in the array so the possibility of a double-failure is much higher ! And Linux-SoftRAID-expansion ? There is one tool that seems to work, but this is very very experimental and time-consuming. You simply need a full backup i think. Uhm... and EVMS ? Doesn't this monster need a bunch of nasty kernel-patches ? You even dont need this GUI (is it much more?), mdadm can do the job too. Compiling a custom kernel is no big deal, especially on Debian it is quite easy : Install "krenel-package" and "build-essential", unpack the sources, configure it and type "make-kpkg kernel_image" and you get fine deb-Packets ;-) First take a look there :

    No this should IMHO not be a problem. I would create one Linux-RAID-Autodetect-Partition on each drive and create it about 2GB smaller than the drive itself so hat you have no trouble if a replacement-drive is smaller. The latest Kernel 2.6.13 contains some important fixes for the md-System so use it ! Also you should set its tick-rate down to 100Hz (250HZ ist default now) an d disable all preemtion-features to prevent this old system from to much interrupts. The favourite FS for this type of usage (large files, not to much overhead, maybe quotas) is XFS for sure. Your CPU should be fast enough but the probably very slow PCI-bus of this system will be a problem.
