Pure Storage FlashArray systems are all solid-state systems, providing NVMeoF-RoCE (called DirectFlash Fabric), FC, and iSCSI block storage access and file access with SMB and NFS. All data is both deduplicated and compressed prior to being written. Pure Storage claims there is no performance penalty for deduplicating and compressing data in-line, which enables an effective capacity ranging between 73 TB and 3.3 PB for their //X products and up to 5.2 PB for their //C product.
With FlashArray //X, Pure Storage has updated their second-generation //m systems that continue to utilize purpose-built controller hardware and a custom NVRAM module. The system has dual controllers with either SAS attached SSDs or DirectFlash modules internal to the controllers attached via PCIe and add-on device enclosures using NVMeoF-RoCE for attaching. In 2019, Pure Storage introduced the FlashArray//C system as a high-capacity flash array utilizing QLC flash.
