1 out of 5 eggsBad Card

Pros: I have nothing good to say about this card

Cons: Loud fan which failed within 5 months
Bad website - no drivers listed
randomly drops hard drives
some HDD's not detected at all
Newegg seems to be the only place that sold this device

Other Thoughts: I had this card installed in my Home server for 8 months. Using it solely as an HBA for JBOD. RAID function was not used at all.

The cooling fan failed on this card within 6 months. Driver support is terrible on product website BUT I did receive updated drivers through email support albeit slow.

Company replaced the entire card with a brand new one but for a fee.

Will most likely never buy Koutech components again.
