That's one more confirmation of corruption issue we discussed in this threa= d. "Cons: Corrupts data when reading from two drives at once (!) Other Thoughts: I bought this to add 2 SATA ports to my desktop. The cheap software-based PCIe --> 2x SATA cards seem to be based on SIL3132 or JMB363 chipsets (this is a SIL3132), but this was more highly rated so I went with it. My intention was to add two individual hard drives to my system, with no RAID involved. Things seemed fine at first, until I used TeraCopy, which do= es a CRC after file copy operations. It revealed occasional mismatches when copying files to either drive. Then I noticed MD5 hashes of files on the drives, taken sequentially, differing without any changes to the files' contents. The final straw was that reading from each of the two separate drives simultaneously would result in silent read errors, to the point whe= re the file would be heavily corrupted but the OS didn't care. I stopped usi= ng the controller and bought a 3ware one instead, and it's been working flawlessly. I don't know if this is a problem specific to this controller= or its chipset, but I would not recommend it." http://www.newegg.com/Product/Product.aspx?Item=3DN82E16815124027 --=20 With respect, Roman --Sig_/IVae.Ua7vPM/LK=CXPze=8I Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAk2n0IYACgkQTLKSvz+PZwgOFgCdGbRKF8CN7gfMEPgVK+/VKzGn 4mYAn1c0PTxvxwoYlcyq1DV1NUsSyigy =Gqhg -----END PGP SIGNATURE----- --Sig_/IVae.Ua7vPM/LK=CXPze=8I--
