Summary: Intel's 320 Series SSD is best compared to the last generation Sandforce SF-1200 drives. The drive offers slightly better performance at a similar price point, but this is not enough to compete with Sandforce's latest SF-2200 controller. One reason is the old Intel SSD controller, another is the lack of support for the new SATA 6 Gbps interface.
Pros: 5 year warranty, Free SSD Migration software available from Intel's website, Supports TRIM, Nice looking, rugged metal case
Cons: Reliability issues, Only average performance, No support for SATA 6 Gbps, High price
Conclusion: The successor to Intel's popular and powerful X25-M, the 300GB SSD 320 Series solid-state drive is a strong performer with some useful features—but its support for slower SATA II makes it seem a little old-fashioned in 2011.
Pros: Increased security features. Inexpensive compared with other recent drives.
Summary: Overall the Intel 320 is an easy drive to recommend. It may lack the headline grabbing sequential transfer rates of the 510 series, but in other respects the drive is a match for its more illustrious and expensive stable mate. As with other Marvell based drives, the 510 series scales with capacity, so the 250GB version of that drive is considerably faster.
Pros: - Amazing small file read performance, - Useful bundle of accessories, - Great software toolbox, - Peerless compatibility and reliability
Cons: - Performance of the latest SandForce drives is far higher
