Typical read/write speeds for Apple Raid card
I have 3 1TB Samsung F3 Spinpoint drives that I am using in Bays 2-4, coupled with Apple's Raid card. Before striping the drives in a raid configuration, I used Disk Utility to write zeroes to each of the disks individually, which took about 3 hours each (this works out to about 100 MB/s, which makes sense to me). However, the third drive, in Bay 2, took much longer than normal to zero (over 12 hours), so I suspected a defective drive. When I striped them using the Raid Utility program, I was able to create a volume and proceeded to test it using QuickBench. Extended Read tests in the 20-100 MB range were only about 30 MB/s. Is this normal? Shortly thereafter, my Raid Utility program encountered an error with the hard drive in Bay 4, which wasn't the same disk I had problems formatting. I took out that drive, removed the volume and raid, and set up Raid Stripe 0 with 2 disks. I am still encountering Extended Reads of about 30 MB/s, no matter if I have cache enabled or not. Any help would be appreciated. Thanks!
I suppose I could select a block size other than 32 kB when I set up the raid, but I wanted to save time to see if any posters have other suggestions.
I know that the windows version of the drive makers utilities are recommended for surface scanning and mapping.
In the case of weak sectors, this is about all you can do.
I may be wrong, but I think Apple has a clause in their manual so that people will buy hard drives from them instead of 3rd party manufacturers.
I am sure that is part of it.
There is also the onboard ROM of the hard drive.
Problem with Apple supplied cards of any kind, is that they have a history of ROM manipulation.
Whether it be crippling (as compared to 3rd party equivalent), or keys to limit performance or compatibility, it is always a question.
I know I am not the only one who has bought their own hard drives for a Mac Pro RAID setup.
I'm sure you are not, and was just "crossing t's and dotting i's" in asking....
BTW, I have 132 MB/s Read, 121 MB/s Write for 2MB-10MB blocks, avg 128 MB/s and 110 MB/s for 10MB-100MB blocks on a 2 drive RAID with WD drives in a 100MHz FSB system.

I'm looking for the read/write speeds for my Mac's.
I'm looking for read/write speeds for my Macs, but I can't find consistent data. Does anyone know the speeds or know where I can look? I have three computers:
iMac late 2013 Fusion/3TB i7
iMac late 2009 1TB i7
Macbook Air 256GB i5
Thanks,I think the feature is called Voice Over, and I think it's now compatible with Reader:

New drives help for APPLE RAID Card RAID Redo
Hi,
I've been happily using an Apple 3,1 MacPro with Apple RAID Card installed and connected to 4-500 GB Apple OEM drives. I'd like to redo my setup and replace the Apple drives with bigger drives. Someone said I could only use up to 2 TB drives - is this correct?
Has anyone done this or anything like it using Seagate Drives that are not Apple OEM. Will that work OK or will the Apple RAID Card want to see Apple OEM drives? Apple sells 2TB Seagates, but they cost a lot compared to non-OEM drives, but will cheaper generic Seagate Barracuddas work OK in every way?
Also, after accomplishing this upgrade, I'd like to upgrade this machine to the latest Lion and possibly even Moutain Lion System Software. Any issues perceived?
To reiterate, I'd like to increase my storage to the max in my Early 2008 MacPro3,1 which has the Apple RAID Card utilizing a RAID5. This is spec'd at "4 - 3.0 Gbps Serial ATA (SATA) controllers" but no mention is made of what the MAX Size drives that will be addressed by the RAID Card.
Thanks, and so long for now, TOMI thought it was an oxymoron to be using Apple RAID card, and to be happy.
It does not support drives larger than 2.2TB
Seagate's just seem to be more trouble. Any enterprise drive should do.
If you really really need RAID5 then maybe this card is useful, otherwise, no.,
There is much less than 300MB/sec x 4 in bandwith, they are shared and not independent, but the total is more like 800MB/sec maximum. Less overhead and other factors comes in more like 700MB/sec total max. \
SSDs have come a long way.
Use a PCIe cards to manage 2 x SSDs of 500GB up to 1TB
Use Disk Utility or SoftRAID 4 to manage 2-4 drive mirror or stripe arrays
10.8.4 has a bug that interferes with using 3TB and larger drives, just introduced bug.
This is the FIRST time there have been limits on drive size. And Apple RAID card. Seems the card is not getting updated firmware to address the need for larger drives. For those using SAS it is also a viable candidate.
SSD on its own to hold the system. 4 x 2TB WD Black for data and media storage. 4 x SSDs for scratch and graphic catalogues and media... all depends what your goal and use and type of programs.
No you do not need to use Apple's.
I cannot vouche for or seen someone doing so but I would hope that WD RED series would be suitable. -
What is the Read/Write speed for a 250gb Serial ATA hard drive?
Hello. I've been having some problems via my Mac (Kernel panic at start up) and is thinking wether or not it is the hard drive.
Does anyone know what the Write speed is for the specified hard drive. I'm currently getting about 5 mbps and that feels a bit slow
I'm on a Macbook Pro mid 2009 model.
Thanks in advance
Ashley.I haven't got the logs. I had to reinstall everything in order to get it to start up (Couldn't find ACPI?)
And I'm only asking because it seems like my laptop HD is running slow. Is it normally about 5mbps for a 5400rpm HDD? -
Read/Write Permissions for FAT32 SD card.
Hi all, after a lot of searching in similar threads I have found no answers to my question.
I have a MobileLite usb drive that takes various sizes of SD cards. I have inserted into it a 256MB regular sized SD card (that which you would find in cameras). I plugged it in to add a file to a folder I had labeled "apps" and the file was clicked and dragged into the folder on the SD card no problem. I disconnected it (safely) and then reconnected it to add another file. Now it is saying that the SD card is read only.
1) The switch on the SD card is NOT set to lock so I know thats not the problem.
2) I backed up all the files onto my desktop, and then went into Disk Utility to see if I could reformat it, but it wont let me.
3) Under "get info" there are no options to change the read/write permissions.
It is to my understanding that FAT32 should be native for both PC and MAC so I dont know whats going on here. Further more, its troubling me that I was able to write onto the SD card, and after unplugging and plugging back in, I now only have read access.
Any takes to this problem? Thanks!You see that's the thing, I'm not using it for a picture camera. The camera prob wouldnt read the card anyway. I'm using it as a storage device for my Nintendo Wii, I have files that I put on there to use as channels for my Wii Home Screen.

What are read/write speeds for Fusion drive?
Has anyone published tests on them? I know Apple is saying they are up to 3.5 times faster for some uses, but have any geeky tests been done? Thanks.
Hi, I'm not finding much, but today's news here has a bit...

Is there a firmware update for the Apple RAID Card [early 2009 Xserve] that will take it beyond the E-1.3.2.0 version and allow it to see 4TB drives?
I have a few of these RAID cards in a couple servers, and then I have an earlier version of the RAID card in a few different servers.
The earlier servers are running non-apple 1.5 TB drives. It will be interesting to learn if this firmware update will indeed allow me to boost the capacity by installing non-apple drives, as the firmware previously has not.
Ohh I'm excited to update and try! This will greatly help out if it does! -
Suggestions for removing Apple RAID Card?
After a year of dealing with problematic Apple RAID cards, and replacement batteries – we are ready to move on, without the RAID card.
We have not yet used it as a RAID – all drives operate discretely, non-RAIDed.
We propose to remove the RAID card to eliminate that point of common failure. Has anyone else faced this, done this? Any suggestions, warnings?
TIA for your kind attention.Hi Michael,
What issues are you having? I had an issue with a faulty battery on a new xserve but once that was swapped out it's been as good as gold. If the drives you have installed have not been raided then you could buy the SATA backplane for the Xserve and swap it out.. Takes about 10 mins to do.
All the best

Are my read/write speeds up to snuff? MacPro Octo 2.26
What are typical and good read/write speeds I can expect on my MacPro Octo 2.26 10GB Ram.
According to iStat, on a simple copy, I get about 65-70 MB/s read from a WD 640 caviar black internal bay, and 65-70 MB/s write to a WD 640 caviar black internal bay. Are there any apple docs that explain what we can expect, how to enhance? You can skip RAID talk, this is just basic stock computer and best operating procedures I'm speaking of. Thanks!
The OS is on a WD 74 Raptor drive.Drives keep evolving.
It depends on what you copy, and what matters, or, where if any place is there a bottleneck?
Newer 10K VR drives maybe, boot drive is important.
SSDs definitely boost system.
Isolating I/O between drives (system, scratch, media, etc) really helps so all the work and I/O is spread out.
Newer 1TB and above drives with 500GB platters and higher density, too.
Best differs from video editing, to mild editing of files, to very heavy work in CS4.
Also, keeping your drives to 50% free space, or what I do for some drives is short-stroke so I really only use one outer partition to work with and use the rest for junk and inactive archive/backup and storage.
iStat - never used it and definitely not for benchmarking drives. -
Apple Raid Card panic on Mac Pro Early 2008 after installing SSD as an enhanced JBOD.
I recently installed a SSD drive in my Mac Pro to replace an aging, original boot drive. I have an Apple raid card with 3 other hds attached - all in an enhanced JBOD configuration. After installing the SSD from OWC (3G Electra SATA II Compatible) everything appeared to work fine. But after 36 hours I received a apple raid card kernel panic alert. See below for diagnostic crash log. OWC support says that their drive should work fine - now I am not so sure. Anyone out there with suggestions/solutions is most welcomed.

What's the difference in Apple RAID card battery error messages?
I have a Mac Pro with 2 quad core Intel Harpertown CPUs at 3.2GHz, and an Apple RAID card. RAID Utility shows that the battery failed but in my research, nobody explains the difference between "Battery failed (code 0x#0 = 17)" (which is what I have) and "Battery failed (code 0x#0 = 18)" or ""Battery failed (other than expired)" (the latter two are what everybody talks about) and what the code numbers mean. Speaking to a local AASP, they recommend that I just wait for a couple of days to see if it's doing the automatic 72-hour reconditioning operation since my Mac Pro is attached to a pretty hefty UPS (2200VA with nothing else attached) and power failures where I live are rare plus the write cache has been disabled so the RAID card is basically doing write-throughs at the moment. But curiosity about the various, different error codes and messages is getting the better of me. Thanks in advance.
Also, what's worrying me (since RAID Utility is so vague) is this entry I found under "Hardware RAID" in System Profiler:
Status:
Charging: No
Conditioning: No
Connected: Yes
Discharging: No
Sufficient Charge: NoAs an update to this, once I replaced the RAID card battery (which was an absolute nightmare--the writer of the instructions at Apple obviously had never done it for real nor seen it done since they omit a lot of important things), the problem went away. But I'm still intrigued about what the error codes mean.

Apple RAID card II - will it work in single CPU Mac Pro 4,1?
Will the Apple RAID card work in a quad core 2009 Mac Pro? I'm refurbing a used Mac Pro I got at a great price and just wondering if I can put in this card (which was "thrown in" with a used 8 core I also bought) with the idea of doing a RAID 10 to experiment with getting top disk read/write performance. I know most do not like the Apple RAID card II but it might be a cost effective way to max out performance on the single CPU, quad core Mac Pro. Ultimately I want to falsh the firmware to 5,1 and upgrade the CPU to a W3690 hex core. I plan to use this box for photography, light video and possibly sound editing. If my plan will result in high benchmarks and provide some fault tolerance I'm comfortable with using the card. I have heard from other users that the new card is much better than the first version and that it actually works pretty well. Any insights appreciated.
Heck!
Im about to win an eBay auction for a blue Apple RAID card together with a pair or SAS 300gb cheetah 15.5k discs for 75 bucks *happy*. Would have been healthy fast upgrade for small investment I thought?!
Guess it probably would have been if the thing worked!?
Why doesnt it work? iPass cable or something like that?
Suppose I still want to go the SAS route with those drives for performance. Any other cards not too expensive that will enable SAS in the Pro?
I use my MP 4,1 as a photo edit workstation but I also keep it on 24/7 for home server, web server, nas, backup etc. So i like to use items that are made for round the clock usage.
Or i just get inexpensive SATA drives and SoftRAID them. So RAID 0+1 is no problem in software RAID?
Thank you guy for quick informed response -

Almost every time I shut the machine down (which I try to do as rarely as possible), it keeps losing Drive 3, the spare.
(See RAID Utility event log snippet below.)
[I wish I could understand why this Apple RAID card keeps losing the spare across power-cycles/reboots, but I digress.]
So I just adopted it as the spare and it spawns the rebuild and many hours later, everything's fine again.
... until the last time I rebooted (Jan. 2nd).
After the usual "I lost the spare" message upon login, it began the rebuild.
But this time, about 11 1/2 hours later the rebuild stopped and RAID Utility reported "Drive carrier 00:03 removed".
Bay 3 is now missing in the Controller view.
I powered off the system last night, and left it off overnight. Today I took all the drives out, blew the dust off and reseated them.
Same thing. Drive 3 is still missing, and now the rebuild task aborted.
The drive bay location shouldn't matter, right? Can I swap the Bay 3 drive with the Bay 4 drive?
I figure one of two things would happen:
(1) It will report Bay 3 as being there but Bay 4 as being missing, same situation as is now. Meaning the problem is in the Bay 3 spare drive.
(2) It will report Bay 3 as being missing (despite a 'good' drive being present) and Bay 4 will be the (unattached) spare, and the RAID set will be unviable. Meaning the problem is with the drive bay itself, not whatever drive is plugged into it.
If "Drive carrier removed" is trying to tell me the disk is bad, why do I not see any log messages about it? I suppose a spare that never gets used could go bad from lack of use, but ... no messages at all?
Hesitant to plunk down $160 on a new spare disk if the present one isn't actually dead ...

RS1 RAID 5 1,2,4 5.23TB 0.00MB Rebuild: 0% complete
I was talking about this.
This looks like a RAID 5 setup without the parity to me. I would said it basically a RAID 0.
Also you metioned "I guess that previous spare must really have gone 'bad', despite having never been used! "
I wiped everything out, I selected the 3 disks and clicked on "Create RAID Set" with RAID5 selected and the "Use unassigned drives as spares" option checked. The 3rd disk has always been marked as the spare ever since then. You do not have a choice to create a "RAID5 setup without the parity". If I wanted a RAID0 I would have chosen a RAID0! raidutil now says

Every time the system would 'lose' Drive 3 on boot, I would just keep rebooting until it was 'found', and then manually re-assign the now-'floating' drive as the spare - and the RAID would rebuild.
There was never a problem until the day that prompted this post - when it would not find Drive 3 no matter what I did. I turned the Mac Pro off for several hours until the drives had all cooled down and it still did not find the drive. I left the machine on but unmounted the degraded volume until I got the new replacement drive.
I really don't understand what you are getting at. It's like you are trying to tell me I set it up as a 4-drive RAID5 with no parity(!) and that I was in grave danger because one of the disks was gone. The actual RAID contents (spread across Drives 1, 2 and 4) were never in danger, unless a 2nd disk had failed while the spare was not seen by the Apple RAID card. I wasn't too worried about that happening. -
Apple Raid Card: Raid-1 volume degrading
Hello,
I have 2 Raid-1 volumes running on a late 2009 mac pro with an Apple raid card. The second Raid volume has degraded now 3 times in the last 2 1/2 weeks. Raid utility is saying that the drive is damaged but when I shutdown, pull the drive out of the bay and push it back in and then restart it says that the drive is good. After assigning it as a spare the Volume rebuilds and lasts about a week until the same thing starts all over again. Perhaps the drive is somehow damaged but it seems more like a connection problem. If this is a familar issue to anyone and someone has a suggestion it would be greatly appreciated.Maybe you need to do a full surface scan for bad or weak failing sectors.
Next time it drops out (or whenever you decide to remove it manually).
Use Disk Utility to Initialize with Write Zeroes option. This takes several hours.
If it completes without any error messages at all, it should then be good to use.
If Bad Blocks are found, they will generally be spared out by this process, and the drive can be good to use for a while, but is likely to fail within 6 months. You should consider moving it to light-duty or occasional use, such as backups.
Sometimes the Initialization will fail. If the drive is still under warranty, return it to the manufacturer for a refund/replacement. Original Apple drives have a one-year warranty, same as your Mac. Manufacturer warranties are often (but not always) 3 years or more. -
Apple RAID Card - Battery failed (code 0x#0 = 18)
Hello,
Upon start up of the computer I get a message that says "The Apple RAID Card installed in your system requires your attention".
When I open up the RAID Utility I have messages like -
Battery failed (code 0x#0 = 18)
Write cache disabled due to insufficient Battery Charge
Can anyone explain what this means and what I should now do?
Do I need a new Battery and does this mean my RAID 5 isn't saving data correctly?
Thanks in advance for any assistance.
KrisHello
I have the same problem too:
Battery failed (code 0x#0 = 18)
or in my case, I am german: Die Batterie funktioniert nicht (Code 0x#0 = 18)
It happened the first time after one year and I replaced the battery. One year later it happened again and I replaced the battery. And one more year later again. This time I decided not to replace the battery.
I booted the system from the recovery media and started the the raid utility from there and it said: battery charging.
So I returned to my "normal" partition and it said: battery charging.
A few days later: Battery failed (code 0x#0 = 18)
I repeaded this several times, always with the same result.
I was quite sure that all the trouble resulted from a firmware bug.
So I did shut down my Mac, and removed my raid card. On the raid card I disconnected the battery and waited a few minutes and reconnected it. I reassembled all and started my Mac.
It is running now for more than a month without any further errors.
