A1247 Apple RAID card compatibility

This would seem a straight forward question but one that as yet I have found an answer for.

I have an A1247 RAID card which was originally purchased for an 8 core Mac Pro (Early 2008).

I would now like to fit the card to a 12 core Mac Pro (Mid 2010), but cannot find any information as to whether the card is compatible or not.

Can anyone help?

Thanks

MacPro, Mac OS X (10.6.6)

I'm researching of upgrade my Mac Pro 3.1 (2008) as it has slow SATA-II connection and now it works very slow on OS X 10.11.6. So, I looked for buying RAID card. But understand that it is SATA-II compatible, not SATA-III.


Also, I don't understand difference between hardware RAID and software raid included in OS X. I have speed up with soft-RAID 0.


Returning to your question.

It is surely uncompatible. And I think it is because of two reasons:

  1. It is SATA-II (but Mac Pro 2010 has SATA-III).
  2. It has the iPass cable. Someway it maybe incompatible with newest Mac Pro's.

The Apple RAID cards are only needed for RAID 5. Their batteries have been troublesome. You should not be looking to the Apple RAID card to speed up your Mac. it will not solve the problem of slowness and will give you a world of different problems.


The first step to speed up a Mac running 10.11 is to be sure you have more than 4GB of RAM, which in the case of 10.11 does improve overall performance. For Mac Pro 2006 through 2008 1,1 2,1 and 3,1 which use FBDIMMs, filling all slots with properly working pairs of modules switches the RAM to double-wide, and returns about a 17 percent speedup in RAM access (which is good, but not game-changing).


The second easy thing to look at is getting an SSD for the Boot drive. The minutia of whether you have SATA II or SATA III does NOT make a tangible difference in operation day-to-day. Just putting an ordinary SSD in a SATA II drive bay as your Boot drive will speed up your Mac in every way. If you can also move to a Boot drive plus additional Data drive organization, that will make a modest additional improvement, as fewer tasks compete for the boot drive.


User Tip: Creating a lean, fast Boot Drive

Sometimes posting an EtreCheck report will highlight something that is not right in the setup of your Mac. Readers will be happy to go over it looking for known troubles. It is not definitive, but can sometimes point out issues you may not have seen.

There is not actually a directory whose name is HOME. That term is a shortcut for the directory that appears in the Finder with the little house Icon. Technically:


/Users/<your_user_short_name>


Moving that directory off the boot drive can speed things up by reducing contention for the Boot Drive. If you are already storing most data on another drive, that is exactly what those articles intend to accomplish automatically, once you change the HOME folder location.

No classic Mac Pro has SATA III drive connections, they all have SATA II including the 2010 and 2012 models. As mentioned by others here the fastest upgrade is a PCIe card with a PCIe SSD drive. It is however possible to upgrade the main drive bays to SATA III if you wish although they will still not be as fast as a PCIe SSD.


To do this the steps depend on which model classic Mac Pro you have, as you have a 2008 aka. MacPro3,1 it is actually easier and cheaper. In your case all you need is a PCIe SATA III card and a cable. You unplug the existing miniSAS cable from the Mac Pro logic board, use an extension cable and then connect it to a suitable PCIe SATA III card.

It is also possible in the 2010 and 2012 models but they require new special drive sleds as well increasing the cost.


Note: A traditional hard disk even if a SATA III drive will not see a noticeable improvement - they are simply too slow, a SATA III SSD drive will however see a big improvement.


PS. The Apple RAID cards are SATA II only and also limited to a maximum drive size of I believe 2.7TB. The card for a 2008 is different to a card for a 2010/12 Mac Pro.
