Your drive isn't EG... I don't remember exactly the different model numbers, but I'm sure they were all EcoGreen. The lower power consumption was the reason to choose these specific drives (different capacities and F2/F3 series tried), with acceptable performance loss - I thought. But it turned out that EcoGreen and NCQ as well as RAIDZ demands dont' fit together... -Harry --------------enigFB6FD41B87E3F0B2C422F57D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk86tPAACgkQLDqVQ9VXb8iYGwCcCTDHkqyjWW4g8/U0H9xFHFfY Mi8AnibROD/RwWoJWEiWaXBPcJpFCZxF =Ahf8 -----END PGP SIGNATURE----- --------------enigFB6FD41B87E3F0B2C422F57D--
