SandForce claims to have tracked down the major bug in the firmware on their latest controller with the help of OCZ and have supposedly fixed it, but OCZ's SSD guy Tony warns that not everyone may see their problems fixed with the latest firmware, though a number of users have found stability with it.
As for the old SATAII drives using a SandForce controller, a number of users are claiming they have died on them in less than a year.
You could go with a
Crucial M4 64GB $110 (SATAIII) or
SAMSUNG 470 64GB $120 (SATAII) or for $5 more the new
SAMSUNG 830 64GB $130 (SATAIII).
Those will probably be the more stable options, based on what you are looking for.
Otherwise just go with a SandForce controlled drive.
SATAII:
OCZ Agility 2 60GB for
$105
OCZ Vertex 2 60GB for
$105
Corsair Force Series F60 60GB for
$105
OCZ Agility 2 80GB for
$125 ($105 after MIR)
OCZ Vertex 2 80GB for
$135
Corsair Force Series F80 80GB for
$130
SATAIII:
OCZ Agility 3 60GB for
$107 ($87 after MIR)
OCZ Vertex 3 60GB for
$125 ($115 after MIR)
Corsair Force Series 3 60GB for
$110
Corsair Force Series GT 60GB for
$120
Even though your listed board only supports SATAII, the SandForce SF-2281 controller, regardless of it's bugs, does scale well, and if you decide to go with one of the new SATAIII drives using a SandForce controller I would go for either the
Corsair Force Series GT 60GB or the
OCZ Vertex 3 60GB.
It's a shame the Corsair Force Series 3 120GB is out of stock, for $15 more you could have purchased it for $140 and then after MIR it would have only been $110.
I actually purchased a Corsair Force Series 3 120GB this summer for my X58 system, even on SATAII the drive was fast, but it did suffer from the random drop outs the SF-2281 has become known for. I just purchased an OCZ Agility 3 120GB last weekend, this is my second day with it.
