The only reason for buying this particular card is because you have an old Mac Pro from 2006 until around 2010, and you would like to use RAID-5. Unfortunately OS X (unlike Linux) does not support software RAID-5, so hardware RAID is one of your only options. These RAID cards are quite old at this point, and the A1228 rechargeable battery is probably long dead. If you want the card to work, you'll need to refurbish the battery, which can be done one of two ways. You can either 1. attempt to buy a new A1228 battery which is going to set you back twice the going rate of the card (over $100), or 2. crack open the battery case and attempt to replace the battery cell yourself. The second option is not very expensive ($15-$20), however will likely require you to order a battery from China which is going to take some time. It's also going to require you to solder in the new battery, so you need to be comfortable doing basic electronics work. The card also only supports SATA-2, which tops out 3Gbps. This is fine for most hard drives, however if you are using SSD drives and want speed, you should look elsewhere. The onboard drive connector on the Mac Pro is also SATA-2 which means you're not going to get any kind of speed bump by using this particular card over what's already in your machine. The Mac Pro does have expansion slots on it, so you could consider looking at other, faster (SATA-3) RAID cards. For a quality one you're probably going to quickly exceed the value of the entire Mac Pro, so that may also not be worth it.Read full review

I was skeptical about the RAID feature for a Mac Pro at first, but it was worth it if adding more HDD into the computer. This accessory allowed all 4 HDD act as one. The most important factor is make sure all your HDDs are equal in GBs. If you have a 500GB to 2TB in your Mac Pro with the RAID card, it would only use the smallest GBs throughout the other HDDs. Just make sure of that factor. Also, max out your RAM which really makes it operate smoothly (no turn beach ball effect) and the Mac Pro will be great!!!
