Review 5405 Adaptec Adapter
(5 out of 5) by MW on Sep 9, 2008 (Winter Park, FL United States)Very easy to install and setup on Asus P5KC workstation.
CD Rom for Driver did not read,and could not make driver disk.In Vista Installation,Vista found driver after looking down into the AM64 file folder, no need to make a driver disk. I installed in "middle"
PCIx slot, which made a difference for other installers.
Came with cable kit, clear instructions for installation,
and fast and reliable.

Fast Is An Understatement
(5 out of 5) by George on Jan 11, 2009I recently built a file server and was going back and forth about whether or not I wanted to use the motherboard's on-board RAID or get this card instead. I ended up deciding to purchase this controller card instead of using the on-board, and I am very glad I did.
If you're not familiar with dedicated RAID controllers, the first thing to understand is that they're not like the on-board solutions; there's a reason this costs more than your motherboard. On-board RAID solutions are typically just a chip with I/O logic for the array, and pass on the processing duty to the CPU. If you're just setting up a RAID 0 array this isn't as much of an issue since it's not that intensive.
However, the problem with this is that any system glitch can possibly result in read/write errors on the array since the system itself is managing it.
What a high-end RAID controller such as this Adaptec 5405 though, the controller card has an on-board processor that manages the array itself, drastically improving reliability and in almost every case, performance.
I connected two 1.5TB Seagate ST31500341AS drives and created a RAID 1 array for my data storage. I installed Vista Home Premium x64 on a separate 750GB Seagate which I connected directly to the motherboard.
After creating the array I copied most of my data from my desktop (Vista Ultimate x64) to the array over my 1Gbps network (see the images for a screen shot of the transfer). The transfer speed is incredible, the sustained write speed to the RAID 1 array stayed within 89-94MB/s.
I should note that I have a high end gigabit network switch (HP ProCurve 1800-G) and you're not likely to get consistently fast transfers over a cheaper (think sub ~$100) gigabit switch. Before starting this transfer I logged into the switch to enable jumbo frames, and in each machine I set the jumbo packet value to 9014bytes (the network switch must support this; I believe most do but you should verify your switch does before changing this value).
