When ReadyNAS vs ReadyDATA

• Benefit: Block-level replication technology

• Words to listen for: DR, BC, offsite backup, any reference to large files, like backups, virtualization, video/media

Replication

• Benefit: Unlike Linux-based storage, iSCSI data (LUNs) can be replicated

• Words to listen for: SAN, virtualization, database, ExchangeiSCSI

• Benefit: SSD caching improves key performance measures compared to SATA-only storage

• Words to listen for: IOPS, latency, response timePerformance

• Benefit: Built-in compression + deduplication for capacity savings and thin provisioning for iSCSI applications

• Words to listen for: backup, dedupe, long-term retention, archivingEfficiency

• Benefit: ReadyDATA guarantees data will never be corrupted, while Linux-based storage cannot do the same

• Words to listen for: disk scrubbing, silent data corruptionData Integrity

• Benefit: Replication to ReadyDATA 5200 enables highly-scalability storage solutions and instant expansion allows for worry-free upgrades

• Words to listen for: compliance, retention policy, capacity planningScalability
