Adaptec RAID 1220SA 2255900-R SATAII PCI Express x1 RAID 0, 1, JBOD Controller Card, Single

Pros: I found this to be easy to install and easy to setup and configure the RAID Array and to setup monitoring. This is an entry level RAID card and preforms great for the price point paid for it.

Cons: The only con is that it takes a while to build the array given that I used new WDC 500GB hard drives. I would only say that if it was possible to proceed past the building of the array while it completes would be nice but this would only be available in the higher level RAID cards.

Pros: Bootable

Cons: Mirror RAID array w/ two WD6400AAKS went to degraded after two weeks, spent 4 hours rebuilding, only to have it go degraded the next day. Sent Adaptec a support question (still not answered). Then today the array failed. Unpluged from 1220SA and plugged into my motherboard SATA conectors and tested both drives (No errors) Booted computer with one drive, and started fine.

Other Thoughts: Frustrating

Pros: Worked as advertised. I was concerned because I was going to have to install the drivers while restoring an image, but it worked fine, no problems at all. Easy to install, easy setup, using it as a Boot array with XP/Raid 1. Fast throughput as well.

Cons: Takes a while to build the array, but that's a one-time thing, so no big deal to me.

Pros: I wrote a review and gave them four stars for low cost low performance. I think low cost is still true for pros.

Cons: However, the building process for 1.5TB mirror with 2x1.5TB drives stuck at 73%. The card reconized the 1.5TB drives as 1.37TB drives, 73% is about 1TB.

So that even the raid building process did not warn my the size limit when I started building, it failed 30 hours later at 73%.

Other Thoughts: I am not sure which RAID controller actually not have 1TB limit. I am sure all RAID card has a limit, but none of them put that in their spec. I am not sure why. Try to contact Adaptec support for resolution of this problem. Have not received any answer yet. If you like me trying to build a mirror raid with 1.5TB or 2TB drives, maybe you could share your success story on NewEgg, so that all Egg finders will learn from you.

Pros: Low cost, small card, works with 1.5T drives to create mirror.

Cons: When one bad sector found, it stopped building the raid! I have a few Adaptec and 3Ware raid cards, all hardware raid. This one has not processor on board. Although it can build raid on its own, it can not do it in background and when ran into bad sector on a hard drive, it stopped right away.

Other Thoughts: Dont' know how to handling error during host processor handling it. The name of this card is called "HostRaid Controller", not just raid. It depends on the host processor to work on the raid. To save your host CPU power, you may buy the most reliable drives. Which I did not think about it before purchased this. If you have critical data, you may consider spending more for a board with adapter processor that can handle bad blocks.

Pros: Simple, small board that looks robust.

Didn't work initially On a Dell PowerEdge T410 which resulted in a "PCIe Training Error" and halted the boot process. I put it into an Intel S5000 system and it didn't do anything.

NewEgg did a good job and replaced it as DOA, but the second one had the exact same problem. I contacted both Dell and Adaptec. Dell never responded and Adaptec said that the board probably isn't compatible with the motherboard.

Finally, I went into the BIOS to map out the PCI IRQ's and opened up IRQ 14 such that no other cards were using it. This got rid of the "PCIe Training Error" and the board was automatically recognized by Ubuntu 9.04-amd64.

Cons: Doesn't share IRQ's nicely.

Other Thoughts: Board uses the Silicon Image Sil3132 chip, so if you have problems with other boards using the same chip, try freeing up IRQ14 (or potentially another IRQ) and see if that solves your problem.

Pros: EZ to setup. works great!!

Cons: None

Pros: If you want a SATA adapter card that will support software RAID I guess it would work.

Cons: This card is NOT a hardware RAID controller. It is a hardware supported software RAID card, otherwise known as fakeraid. Adaptec HostRAID is just marketing speak for software based raid. If you want a real hardware raid card you will need to spend over $150.

Pros: Decent price, hardware RAID, good throughput.

Cons: None so far

Other Thoughts: Set up with two WD6400AAKS in RAID1. No performance hit in WinXP Home set as boot drive.
