I have recently ordered an LSI Logic MegaRAID SATA 150-4 (PCI RAID
Card). The card does use true hardware RAID so the computer will
recognise it as a simple SCSI device.
I am planning on running 3 WD Raptor (36.7G, 10000 rpm, 5.2 ms seek,
2.99 ms Latency, 8MB Cache, SATA 150) drives as RAID0 ... with regular
backups
The problem is that I have received contradictory information. The card
can run on either 32 or 64 bit PCI mode. I have been told two different
things:
1) If you run a RAID card on a 32 bit 33Mhz PCI port the maximum
theoretical speed would be 132Mb (32-bit/8*33Mhz)
2) The max. theoretical speed does not apply to true hardware RAID
cards as they would run over the SCSI bus (recognised as standard SCSI
disks).
Which of these comments are actually true?
Also,
Is it worth running 3 Raptors over PCI?
