for the cheapest raid card and the cheapest hard drives? what were you expecting?

it was the write cache! now writing at 40mb/sec reading at 60mb/sec

Hi thanks for your comment - the machine is a core-duo (E6600) with an ASUS P5W Deluxe motherboard. It uses two WD drives (7200rpm) in Raid0 on the onboard controller for C drive... I will check if the cached writes are on I would rather not switch to raid10 as the array already has about 5.6tb...

the array sits as drive E on a vista64 machine (using a 7200rpm RAID0 C drive) if I copy a large file from C to E, it transfers at about 10-12mb/sec if I copy from E to C the speed is more like 60mb/sec!

Hi any help is appreciated: 8x Samsung Spinpoint F3 1.5TB on LSI MegaRAID SAS 8208ELP RAID5 Real world rrite speeds about 10mb/sec! and reads about 60mb/sec HD Tune shows a different picture: can anyone tell me why write speed are so slow?? thanks

unclear - i just assumed win xp 32-bit would have trouble with a 12TB logical drive, so i had a low threshold for moving on to server 2003 64-bit, which i am trying out currently!

just to give you an update: in the end I got an LSI MegaRAID SAS 8208ELP card i'm just about to set up Win Server 2003 (64-bit) and build my RAID5 array on that... I actually tried using the card with a Win XP 32 bit system but the newly-initialised RAID5 drive was just not visible at all...

perhaps I've been lucky but WD drives have always behaved themselves with me... As for hardware Vs software raid - most of the hardware controllers have quoted MTBF of hundreds of years - sure, they can still go wrong but software raid requires more components to remain failure-free

has anyone used the adaptec ASR-4800SAS cards? I can get one (including the sas-sata cables) for about half the price of the perc 5i .... thanks

thanks those PERC cards look interesting - I see there are additional batteries / memory modules etc - are they necessary? I would prefer just a card that doesnt need upgrading! lol

hi I have 8x samsung F2 1.5TB drives (eco-greens), and I want to build a hardware raid array (operating on Raid5 or Raid6) - for my new media server (running win xp pro) which already has a 2x WD boot disk (raid0) on a ASUS P5W DH deluxe motherboard having looked at a well-known auction site -...
