The Adaptec SATA II RAID 2420SA and 2820SA deliver industry-leading performance and RAID data protection. Plus, since they are RoHS compliant, system integrators can design and qualify server and storage solutions today that already meet the industry's Reduction of Hazardous Substance requirements.
Adaptec SATA II RAID Outperforms LSI, 3Ware, Promise
When you're looking for the best performance for your SATA or SATA II environments, look to Adaptec. We are committed to providing the best-performing RAID controllers in the industry. Unlike other RAID vendors who advertise unrealistic workload, Adaptec measurements demonstrate how your RAID controller will hold up under a real-world application environment.
In a series of recent performance benchmarks* the eight-port Adaptec Serial ATA II RAID 2820SA outperformed the LSI300-8X, Promise EX8300, and 3Ware 9550SX in a variety of the most common workloads generated by today's applications.
The Most Complete Data Protection
Adaptec RAID has been optimized to deliver the best overall performance. However, choosing the Adaptec SATA II RAID 2820SA or four-port Adaptec SATA II RAID 2420SA also gives you the Adaptec Advanced Data Protection Suite for the industry's most advanced data protection.
In addition to RAID 0, 1, 5, 10, and 50**, these controllers include RAID 1E, 5EE, 6, and 60** as well as Copyback Hot Spare and an optional upgrade to a Snapshot Backup feature.
