Areca’s new PCI Express SATA II RAID controllers
. The new Areca SATA II RAID controllers are available in three models—ARC-1230ML, ARC-1260ML and ARC-1280ML with 12, 16 and 24 SATA II ports respectively. These Areca SATA II RAID controllers will also support mini SAS connectors by allocating four SATA II ports too. There’s also an ARC-1280 model that lacks the mini SAS capabilities.
The PCI Express x8 based Areca SATA II RAID controllers are based on Intel’s 81341 I/O processor clocked at 800 MHz. One 240-pin DIMM slot is available as a cache and comes with 256MB of DDR2-533 ECC. Memory can be upgraded to 2GB with another DDR2 memory module. Non-ECC memory modules are supported as well.
RAID levels 0, 1, 1E, 3, 5, 6 or JBOD are supported. Native command queuing is also supported. The Areca SATA II RAID controllers also support staggered spin-up and spin down when hard drives are not in use. An Ethernet port is also available for management purposes too.
Availability is unknown as the Areca website still states the controllers as “Coming Soon.” Pricing should be fairly high as expected of server-class SATA II RAID controllers.

I have actually used an Areca ARC-1170 (24 Port PCI-X to SATA II) for almost a year now on a 5U server with 24 hot swappable 250GB drives. I have 22 Drives configured in Raid6 and 2 hot spares for a total of 5TB. This is my backup server which uses stagging, keeping backups on disk for up to a month for rapid access. It also dumps the backups to tape for off site storage. I love the Areca controllers, they are fast and reliable. I replaced two 12-port 3ware cards with the Areca controller and is one of the best decisions/investments I have ever made.
Even though the system was originally purchased with old SATA 150 drives, the performance is very good with the Areca controller. Here are some Bonnie++ benchmarks I ran:
