Adaptec ASR-6805T 512MB SATA/SAS 8 Port RAID Controller

SKU CH-FDCA-Q4D8H

Eight-port SATA and SAS RAID controller with 512 MB cache and low-profile brackets

  • TypeController Card
  • Eight SATA and SAS ports expand storage capacity
  • 512 MB cache accelerates read and write performance
  • PCI Express interface delivers 6 Gb/s throughput per port
  • Low-profile bracket fits compact chassis designs
  • Hardware RAID offloads parity calculations from the host CPU

Eight-port SATA/SAS RAID controller

The Adaptec ASR-6805T is a RAID controller card that connects eight SATA or SAS drives through a PCI Express slot. It includes 512 MB of onboard cache and supports 6 Gb/s transfer rates per port. The card is suited for workstations or servers that need hardware RAID across multiple disks.

Low-profile bracket for dense builds

A low-profile bracket is supplied so the card fits in 2U or slim chassis where a full-height bracket cannot be used. The eight internal ports free external bays for other uses while keeping all drive connections inside the case. A compatible PCI Express slot is the only host requirement.

Sustained throughput with hardware RAID offload

Hardware RAID processing moves parity calculations off the system CPU, so sustained read and write loads stay steady during long rebuilds or heavy database work. The 512 MB cache absorbs write bursts and helps maintain consistent latency under continuous multi-drive activity.

Questions about this item

How does the 512MB cache handle sustained write workloads on the ASR-6805T?

The 512MB onboard cache buffers incoming writes and flushes them to the SATA or SAS drives at up to 6Gb/s per port, keeping throughput steady during long transfers.

What thermal or acoustic behaviour should I expect when the ASR-6805T runs continuously?

The card is passively cooled and draws power only from the PCI Express slot, so it adds minimal heat and no fan noise inside the chassis.

Which host interface must my motherboard provide for the ASR-6805T to operate?

A free PCI Express slot is required; the controller connects through that interface and does not need any additional host-side connectors.
