List of real SATA RAID Cards for Linux

Source: hxc.hu, pawel_231, 372519

I am looking for a real RAID card for my Linux server, which will act as a RAID 1 for two SATA drives. It turns out that many of the cheap RAID cards are “fake raid”, and their manufacturers are trying to hide this fact.

So I decided to do a quick research on the internet about available RAID cards for Linux 🙂

What is a “fakeraid” card?

A fakeraid card means that it is essentially a 2 or 4 port SATA card with additional hardware and BIOS code. In order for the operating system to use the RAID feature of the card, a driver has to be installed, which will do all or part of the RAID logic on the mainboard’s CPU. This means that what you get is actually a software RAID, and not a true hardware solution.

So if you have a fakeraid card on your Linux box, you better off using Linux’s built in software based RAID feature.

Since there is not once place on the net that has a list of true RAID cards, I decided to put my own list here. Please feel free to send information about additional cards.

One thought on “List of real SATA RAID Cards for Linux

  1. Fifo

    I have 2 HP AMD Opteron DL servers with this RAID Cards: HP SmartRaid P400 and HP Smartraid P410.
    This cards are real RAID and I can install a Debian/Ubuntu distributions without problems.
    In others aspects, I just have problems of lower performance in IO. But it’s work and actualy are in production systems.

    Thanks for this list of raid cards. I want replace this cards for newer version for SSD Disks and it’s dificult found information of this type.
