IBM FlashSystem 5600
Current-generation 1U NVMe FlashSystem for smaller mixed workloads, compact OLTP, IBM Power attachment, edge deployments, and buyers who need a serious array without jumping to the 7600 tier.
FlashSystem 5600 is the compact current-generation choice in IBM's 2026 FlashSystem line. It is the first model many buyers should evaluate when they need low-latency block storage, FCM data services, and IBM Power attachment without sizing into a larger enterprise frame.
Use the 5600 as the starting point for smaller mixed workloads, 20 TB to 80 TB effective-capacity conversations, compact IBM i estates, and branch or edge environments where a 1U footprint matters.

Frequently Asked
Which IBM FlashSystem should I buy?
Start with workload, usable capacity, latency target, host count, replication, and recovery requirements. FlashSystem 5600 is the compact current-generation starting point, 7600 fits larger mixed workloads and 7300-class refreshes, 9600 is the flagship path for critical consolidated workloads, and C200 fits backup, archive, and capacity-optimized use cases.
Is IBM FlashSystem 5300 still relevant?
Yes, for installed-base, reseller-inventory, datasheet, and refresh research. The AS400/Midland warehouse shows FlashSystem 5300 as the strongest model-specific FlashSystem query. For a new current-generation quote, compare the 5300 question against FlashSystem 5600.
