Dell PERC H745 RAID Controller Adapter

Dell PERC H745 RAID Controller — 8GB Write Cache 12Gbps

The Dell PERC H745 controller is Dell’s high-performance PERC RAID adapter for PowerEdge servers. Its defining feature is an 8GB non-volatile write cache (NVRAM) — a battery-backed memory buffer that captures write I/O in cache before committing it to the physical drives. This cache transforms random write performance for workloads that generate high volumes of small random writes — database transaction logs, virtualisation metadata and email server storage that are highly sensitive to write latency. The 8GB cache capacity handles substantial I/O bursts before needing to flush to physical storage.

Beyond the write cache, the Dell PERC H745 controller provides full PERC-class RAID coverage from RAID 0 through RAID 60 with 12Gbps SAS and SATA connectivity. SAS drives deliver higher IOPS and lower latency than SATA drives. They are the preferred media for performance-critical PowerEdge deployments. SATA drives provide a cost-effective alternative for capacity-optimised configurations where storage density matters more than absolute performance. Full iDRAC management integration provides RAID health, rebuild status, predictive disk failure alerts and write cache status visibility through the iDRAC interface.

H745 vs H355 Selection

The H745 includes 8GB non-volatile write cache. The H355 does not. For write-intensive production workloads, the H745 provides substantially better write performance. For read-optimised workloads or capacity storage, the H355 is sufficient. Browse Dell server RAID controllers from the Briggi Tech components range.
