If you look at the ATTO STRs and cache transfer rates[1] the ARC-1120 (PCI-X) is up against the bus limit. theoretically the 1120/1220 could do up to 2400MB/s (8 drives * SATA-II transfer limit of 300MB/s). The results of the Areca ARC-1120 in the RAID 0 tests cleary show this adapter does not have any trouble with ATTO's tiny dataset. Floating high above the crowd, the ARC-1120 has a perfect view on the struggles of the other adapters. Exceeding 750MB/s, the transfer rates from the Areca ARC-1120 are almost equal to the effective bandwidth of the 133MHz PCI-X bus. [1] [1] http://tweakers.net/reviews/557/18 The only difference between the ARC-11xx and the ARC-12xx's Intel XScale processor is the IOP333 on the ARC-12xx* has a PCI Express to PCI-X Bridge... Both chips are otherwise identical and both chips use PCI-X133 internally. Also it appears the IOP333's internal bus operates at 333MHz while the IOP331 operates at 266MHz but I can't confirm this, it's possible older IOP331's worked at 266MHz but new ones are 333MHz now. ftp://download.intel.com/design/iio/prodbref/25341301.pdf ftp://download.intel.com/design/iio/prodbref/30658301.pdf *The ARC-1210 uses a IOP332. I decided to go PCI-Express. The deciding factor was that PCIe slots on my motherboard have a direct connection to the Intel 5000p MCH (north bridge) whereas PCI-X slot are connected to the Intel ESB2 (south bridge) using a PCI-X to PCIe 8x bridge... The choice was very easy to make after I notice this. -- BSD Podcasts @: http://bsdtalk.blogspot.com/ http://freebsdforall.blogspot.com/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
