And yes, they're very cheap so that you have to do things like filemarks and data defect management in the driver. But- not bad for a drive that's < 500$. A comparable drive is at least a DLT 7000- that's still 7K$, right? And then you start getting into the STK and high end IBM or Ampex drives- 25K$ and higher. If I were the tape drive divisions of these companies, I'd be sweating a bit now. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
