Actually, you should be able to squeeze maximum performance from the drive with a plain U2W (80MB/s) adapter. U160 is way overkill for a single drive, and U320 would be even more so. According to the data sheet, the fastest hard drive IBM currently seems to be shipping has a sustained data rate of 36.6-52.8MB/s: http://www.storage.ibm.com/hdd/ultra/36z15data.htm Other manufacturers can't be far off. -- Christian "naddy" Weisgerber naddy@mips.inka.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
