...well,- Unless RaidCore is trying to peddle their VST Pro software,...aka as Fulcrum proprietary based ? which BTW you said no to, I don't see any advantages here. Why?, ZFS is free ! And, where are the Drives for Solaris, or the xBSD's , or even MacOSX !!!?-and still no, becuase their newer 54xx series doesn't support the other 'ix OS's. Nope, unfortunately, not much to see here.so, based on the above, Adaptec 5805,... or Areca,... blows this.-Rikster
Factors like spindle speed, density, latency etc. effects drive performance as much or more than bandwidth. A 300GB 2.5 15K SAS drive will smoke a 1TB 7200 SATA drive simply because it has about twice the IOPS. The bandwidth is meaningless if you can't get the data on and off the disk at the speed of the bus. Furthermore, except for the WD Velociraptor 10K+ spindle speed drives are non-existent in SATA but are prevalent in SAS. So from an interface standpoint they are very close but SAS drives are really intended for entirely different markets and applications and budgets I might add.
