I also use the Intel RAID cards as well as the 3ware cards. Both preform very reliably for me. The newest Intel SATA card (SRCS16) appears to be a re-labelled LSI card and seems to work well using amr: amr0: <LSILogic MegaRAID> mem 0xf0000000-0xf000ffff irq 16 at device 1.0 on pci3 amr0: <LSILogic Intel(R) RAID Controller SRCS16> Firmware 713K, BIOS G401, 64MB RAM amrd0: <LSILogic MegaRAID logical drive> on amr0 amrd0: 476920MB (976732160 sectors) RAID 5 (optimal) Mounting root from ufs:/dev/amrd0s1a whereas the older Intel card uses the iir driver - no more unified driver for the Intel cards! =( As a general rule of thumb, you want to stay away from the SATA RAID built into the chipsets (like the ICH5R). These are only going to be good for entry level stuff like RAID 0 and 1 anyways. Support for these is in the works, but if you need a good card now, grab an Intel or a 3ware. They both do hardware XOR and are pretty reasonably priced. -Sam ----- Original Message ----- From: "Mark Picone" <wts666@iprimus.com.au> To: <freebsd-hardware@freebsd.org> Sent: Wednesday, November 17, 2004 12:20 AM Subject: Re: Looking for supported 32 or 64bit/66Mhz SATA Hardware RAID 5 Controller on 5.3-STABLE > Hey, > I had to research this a few months ago, and i found that intel sata > raid5 cards are the best > compared to the 3ware sata range in the way of stability and support > on freebsd, duno about > Promise, but make sure the card has an XOR processor on it to take > some load of the cpu, all > intel raid cards use the same driver which is handy. > > -Mark > > > Vulture wrote: > >>Hello All, >>I've seen some posts on this before with no results.
