Correct. > Hardware RAID cards typically have relatively huge chips with > heatsinks, This isn't a very good description. There are non RAID HBAs that have large heatsinks as well. ASIC package (chip) size is irrelevant. This is a result of the lithography feature size (65nm/40nm/32nm) not the complexity of the logic. > battery-backed onboard ram, and cost $300+ new. Real hardware RAID HBAs do have DRAM on board, anywhere from 128MB to 2GB. Most RAID cards ship without the battery module. It's optional. And your price point is high. Adaptec's entry RAID cards are very reasonable. Newegg has 5 models from $199-245. All have 128MB DRAM and support RAID1/10/1E but not 5/6. So I'd say "$200+" is more accurate. Most that support parity arrays are typically $300+. > Go ahead and use software raid instead. If you're sticking with that Sil3114 card then yes, use Linux md/RAID (mdadm). Performance, compatibility, troubleshooting, etc will all be better than fakeRAID. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
