Areca PCIe Gen 4 M.2 NVMe Hardware RAID Adapter

ARC-1886-6n2i: 6x M.2 Slots + 2x SATA Ports

Ultrafast Transfer Speed

ARC-1886-6n2i PCIe Gen 4.0 M.2 NVMe Hardware RAID adapter is built to deliver unprecedented performance, using only carefully, best-in-class components. These include the dual core Broadcom SAS3916, PCIe Gen 4.0 tri-mode ROC, 8GB DDR4-2666 SDRAM with ECC protection

Powerful Broadcom Tri-Mode ROC Engine

At the heart of ARC-1886-6n2i is the incredibly powerful Broadcom SAS3916 dual-core ARM A15 tri-mode ROC, giving efforless performance as desirable. It delivers storage interface PCIe Gen 4 NVMe, 12Gb/s SAS, 6Gb/s SATA and the security of data protection. Damage in a software RAID is considered as the consumption of massie computation and memory bandwidth on the host. The ARC-1886-6n2i hardware RAID releives the parity generation burden from the host and maximizes application processing performance.

Speed up to 8GB DDR4-2666 SDRAM

With a massive 8GB of DDR4-2666 SDRAM, the ARC-1886-6n2i gives you super-smooth multitasking during the period of high overload in 4K environment. ARC-1886-6n2i firmware can configure how much cache SDRAM dedicated for read, and how much for write. If your server application has significatly more reads than writes or more writes than reads, you might need to chage this setting to adjust the read/write cache ratio for improving performance. Big cache is the perfect choice for a 4K/8K application drive, making your professional apps work as fas as possible.
