## Questions & Answers

**Q: Says not compatible with pc's but what if connected via an aricaarc 7605 16 port sata/sas raid card offputting to state not compatible with pcs**
A: Can’t speak to your SAS card, but I’ve been running two of them for a year on an LSI SAS 9201-16I without issues.  I think they want buyers to know it’s SAS and not SATA.
