Fusion drive and logic?!

hi all, im going to have a new i mac i7 27 inch and bought it with a fusion drive. i saw some articles that claim fusion drive isnt good for logic work??
please let me know if its true and if I now have to start worry
thanks.. and hope it was good decision to buy the fusion drive.

As a single internal drive, no... a 7200rpm drive won't help...
You need a seperate drive for your OS X and another drive for your samples...
If you were thinking about patitioning the internal 3TB drive.. Partitioning such a large drive actually slows down the performance of the drive... and trying to run everything off an unpartitioned single drive is not a good idea either... though better than using partitions.
Personally, I'd get the smaller internal ITB HD for OS X and Applications etc.. and then use the $150 saved to get a fast 7200RPM FW800 (using a Thunderbolt to FW800 adaptor) /USB3 (Though be aware often FW800 drives often perform better than USB3 drives because of the overheads USB3 places on the system) or Thunderbolt external HD and use that for your samples/projects.

Imac 27 3.4GHz Quad-core Intel Core i7,with 1TB Fusion Drive and logic

hi all, i just upgraded my old imac and now im going to have the 27 inch 3.4GHz Quad-core Intel Core i7,with 1TB Fusion Drive
how will logic is going to work? is it much better than my old i3 21.5 imac? i didnt like to work with my old imac, was very laggy.
thanks
Arad.

Anything purchased after mid-July has EFI (like BIOS in PCs) that only likes Lion. Maybe some up through mid-August could possibly run SL, but anyhing sold last week is Lion-only.
A very lucky few accidentally receive a SL-system when they buy new, but very few.

HT5446 If I buy a mac mini with a fusion drive and add windows using boot camp, can I make the SSD function be dedicated to the windows partition?

If I buy a mac mini with a fusion drive and add windows using boot camp, can I make the SSD function be dedicated to the windows partition?

Additional information from Linc's post. Basically, only one additional partition can be added to a Fusion Drive and it resides on the HDD.
Do computers that come with a Fusion Drive support Boot Camp?
Yes. Use the Boot Camp Assistant to create a Windows partition and install Boot Camp. The Windows partition will exist on the hard disk drive, not the Flash drive, and is not part of Fusion Drive Logical Volume Group. 3TB Fusion Drive configurations need to update to OS X Mountain Lion v10.8.3 or later to install Windows 8. See iMac (27-inch, Late 2012): Boot Camp alert with 3T hard drive for more information.

I am planning to buy an iMac 21.5 inch with Fusion drive and 16 GB RAM while i visit USA for a conference. My country of origin is India. Once i am back to India, will my iMac be covered by the Apple's Protection Plan?

I am planning to buy an iMac 21.5 inch with Fusion drive and 16 GB RAM while i visit USA for a conference. My country of origin is India and the option of configuring to my need is not avaialble here in India. My concern is once i am back to India, will my iMac be covered by the Apple's Protection Plan if something goes wrong here in India?
I recently came across some posts regarding International warranty related issues for iPhone and iPad....hence this crossed my mind...
Waiting for response from the support group members...

Thanks Ralph
This essentially means that if my iMac develops some problem (both software and hardware) in my country (India), it will be completeley attended (even the whole system requires replacement) by the AASP in India...is that what you say?

Hard drive crashed on my MacBook pro and had to replace drive and logic board. When I connect my iPhone and try to sync I get a dialog box stating iPhone is synced with another iTunes library, erase and sync? How do I sync with iTunes without erasing?

Hard drive crashed and had to replace drive and logic board on my MacBook pro. After Install tried to sync with my iPhone and a dialog box pops up stating "this iPhone synced with another iTunes library, erase and sync?". I checked the manually manage music and videos box because I don't want all my wife's pics and music on my iPhone. How do I Sync without erasing what I have on my iPhone???

It's not crap at all.
It's not that simple. For example, I've 3500 songs on my MacBook but don't want them all on my phone, so I have to manually select each song again???
There has to be a solution.
Why not simply make a playlist with the songs you want on the iPhone?
and maintain a current backup of your computer.

Fusion Drive and sleepimage

Hello,
if you buy a new Mac with a Fusion Drive, where does OS X put the sleep image? On the SSD or the HD?
By "sleep image", I mean the file that holds the RAM while the Mac is in hibernation mode. It normally resides in /private/var/vm and is named "sleepimage".
Markus

I would guess the SSD, if only because it will allow the Mac to go to sleep faster.
Also the few articles I've seen about Fusion is that all writes go first to the SSD, then some time later Mac OS X may decide to migrate the data to the HDD. But since the Mac is now a sleep, there is no later. And if the Mac needs to use the Sleep image when it is woken up, the Mac would recover faster if the SleepImage was on the SSD.
All of the above is total speculation. I do not have a Fusion Drive, and I have not read anything about where the SleepImage is stored when you have a Fusion Drive.
ArsTechnica.com has a very good article about the Fusion Drive.

Fusion drive and external data drives

How does Fusion drive behave if you have data on an external device? I just odered a new Mini and I'm a Logic user with hundreds of GB worth of data on an external RAID 5 exclosure. Will files stored on the RAID be copied to the Fusion Drive when accessed frequently, or will that functionality be strictly for the boot volume?
Thanks!

You can definitely create a Fusion Drive using an external drive to add capacity, and in fact it can be a great thing to do as the SSD will eliminate most of the latency involved.
The SSD will contain whatever the most frequently used blocks are, and these will moved from your HDD(s) onto the SSD to provide the performance improvement. This means you could potentially end up with any number of your working files on the SSD depending upon how often you use them (or have been using them recently). This is important to keep in mind; the SSD in a Fusion Drive is not the cache as a cache-disk, meaning that if the SSD fails you will lose data and have to rebuild your Fusion Drive from backups.
This will essentially eliminate the redundancy advantage of RAID-5, as while you can replace any HDDs that fail as normal, an SSD failure will render the volume unusable.
I'm actually currently interested in whether a RAID-1 of SSDs can be used within a Fusion Drive, as it could allow the SSD part of the Fusion Drive to be given redundancy too, in which case the setup would be safe as it'd be 2x SSDs in RAID-1 + HDDs in RAID-5, giving you one to two disks worth of redundancy. However I suspect it won't work, as I believe Fusion Drive just queries each disk to determine if it is an SSD, and of course an Apple RAID won't identify itself as such.

Fusion drive and backup/restore issues

Hi,
since I installed a fusion drive on my early 2008 iMac, consisting of an internal 256GB SSD and an (external FW800) 320GB hard disk, I occassionally run into trouble when system updates are pending. In the past, at worst the time machine backup couldn't be restored and I had to reformat and reinstall the system from scratch - which is not really comfortable!
Currently, running Mountain Lion, when I try to select the startup disk, it complains that Boot-Caches on the Boot-Helper-Partition cannot be created. Nevertheless the system starts fine (and runs fast ;-).
Before upgrading to Mavericks, I would like to know
- if someone else ran into similar problems with fusion drives, when updating/upgrading system software.
- Is it normal that a Time Machine backup cannot be (completely) restore a Fusion drive?
Yes, I know that having the harddisk part of a fusion drive externally is not recommended/supported by Apple - and my Mac is nearly 6 years old, but that would not explain why system updates/restores nearly always fail and sometimes the Time Machine backup drive has a broken file system (needed reformatting)! And I always checked the disks with Disk Utility prior to updating...
Any comments are appreciated.

You can file feedback here. The more who file the more the faster the issues may be fixed.
Also you shoud look on the CCC forums.

DIY Fusion Drive and RAID 5

Hi everyone!
I have spent several hours by reading various forums but haven’t found any definitive answers.
I have a 12 Core Mac Pro with the following setup: one 1TB SATA hard drive that carries the system and applications. For the files and storage there are three 2TB SATA drives in RAID 5 controlled by Apple RAID card. I am going to install a 512 GB Samsung 840 Pro SSD drive in the optical bay and have initially planned to use it just for the system and applications, but am curious if the following is possible.
1) Is it possible to combine the RAID 5 array with the SSD and create a Fusion drive?
2) If yes, will it retain all the features of the RAID 5?
3) Should TRIM be enabled?
Thank you in advance!

TRIM directly addresses the shortcomings of having only garbage collection available. SSD controller manufacturers and designers (including SandForce, the controller manufacturer for OWC's SSDs), recommends that TRIM be used with their products. So does Samsung.
For example, here's a 2011 article from OWC describing how you don't need TRIM on their SSDs and how it can in fact hurt performance or reliability.
That article has been discussed here on MacInTouch before. In my opinion it's bad advice, and inaccurate in some of its assertions. It also ignores the recommendation made by SandForce to use TRIM with their SSD controllers. But even if one were to take that article at face value, applying that advice to SSDs other than OWC's makes little sense.
The reason I'm advising against TRIM is simply that it's yet another driver-level modification of the OS, and these always carry potential risk (as all the folks with WD hard drives who lost data can attest to).
Apples and oranges comparison, for a variety of reasons. The short of it is that TRIM is supported natively in all recent versions of OS X. The tools used to enable it for third party SSDs do not add a new kernel extension; they change the setting to allow Apple's native TRIM implementation to be used with SSDs other than those factory installed by Apple.
This shows that the 840s do work slightly better with TRIM than without, but the differences are (in my opinion) trivial, a 9% increase at best.
One of the major reasons for the skepticism that exists about TRIM is that so many people, the authors of both articles you linked to included, don't understand it.
TRIM is not, strictly speaking, a performance-enhancement technology -- though it is plainly obvious that most people think it is.
Though it can, in many circumstances, improve performance, there are also circumstances under which it will provide little or no noticeable benefit. Not coincidentally, a new SSD tested fresh out of the factory packaging is unlikely to show much (if any) benefit. Or rather, TRIM is providing a real benefit for new SSDs, but that benefit doesn't become measurable in terms of benchmark performance testing until every memory cell in the SSD -- including many gigabytes of cells hidden from visibility by the SSD controller -- have been written to at least once. Writing 128 GB of files to an SSD with a nominal capacity of 128 GB won't do it, as there are several gigabytes (exact number varies depending on the model) still unwritten.
Under real-world use conditions, having TRIM disabled means eventually having noticeable write performance degradation due to write amplification. It is far greater than "9%" -- it can be a 50% or greater drop in write performance, depending on various factors. Defining "eventually" is difficult because it depends on how the SSD is used. But given enough time and write cycles, it can happen to all SSDs used without TRIM, no matter how sophisticated their garbage collection algorithms are.
Under those same real-world use conditions, having TRIM enabled means that the SSD should almost never reach a state of having noticeable write performance degradation, as it should almost never get into a state where write amplification is happening.
I will concede that it is possible to design a lab test in such a way as to defeat the benefits provided by TRIM, but such tests do not reflect any real-world usage scenario I can imagine. Furthermore, those same contrived tests would put an un-TRIMmed drive into an equally-addled state even more quickly.
I would suggest reading through the rather lengthy previous discussions about TRIM. Here are a couple of my past posts that are most relevant to the current discussion:
A description of what TRIM is here.
I addressed some of OWC Larry's comments about TRIM use with OWC/SandForce SSDs here.

Hard drive and logic board failure

Hi everyone,
we have been suffering from 4 dead hard drives and one logic board failure in 20-inch intel iMacs (~2007) recently and last month the logic board and hard drive of a 2010 27-inch iMac (just out of warranty) just died.
Are there any known issues with the iMacs that Apple fixes even outside the warranty?

Frank: I have a 5 month old 27" iMac and the logic board on it just died as well as I was getting all kinds of kerner errors. I have Apple Care and although the cost to replace the product was $800 I am not going to have to pay anything. I did talk to someone else who also had a logic board go bad on him but I doubt that you will be able to get it fixed without having to fork over $$$

Replaced Hard drive and logic board on ipod 5.5g...still get sad ipod HELP!

I've tried searching around the forums to see if anyone has had this similar problem AFTER replacing the hard drive in their ipods. Of course there are tons of people with similar issues, and the responses are always "replace the hard drive", so I'm going to see if there are any other possible issues out there that I could look into. So here's my situation specifically.
I have an ipod video 80 gig, and it seemed as if the hard drive pooped the bed on day 366 (only a slight exaggeration) after purchase, putting me right outside of my warranty. The apple store wouldn't do anything without charging me the cost of a new ipod to repair it. So, it had been sitting in my desk drawer for almost a year when I finally got around to replacing, and upgrading, the hard drive. I found a 120 gig drive on ebay, which after an email confirming my model, the seller said should work as a replacement. After installing the hard drive, I got the same exact problem that I had before. It would say to "wait. low battery", then the apple logo would show up with no back light, and then it would go right to the sad ipod face. I left it charging for a couple of hours, and it would just keep cycling through those three screens, until dying eventually after unplugging it. If I hook it up to my computer, nothing happens besides the ipod trying to charge. When I try to force it into disk mode, it seems like the ipod will reset to the apple logo screen, but it goes right back to doing the same little dance. I tried opening it and checking the cables a couple of times, and the last time, I broke the little cable clamp that holds the lcd ribbon. So...I ended up buying a replacement logic board. I installed that, hoping the logic board may have been the problem all along, and as soon as I plugged it in...same old crap. Now, in a last ditch effort, I've ordered a new hdd ribbon to see if that remedies the problem.
I realize that I should have perhaps waited a week until it comes, to see if that fixes it. But to be honest, I can't see anything wrong with the hard drive cable that I have right now, so I remain doubtful that it's going to fix anything. What I'm wondering, is if anyone has any idea if there is something that I may have overlooked, or if I might be barking up the wrong tree? Is it possible that the hard drive that I ordered was broken when I installed it? The seller (who seems to be a reputable seller on ebay, with lots of positive feedback) said that they test all of there hard drives before selling/shipping, and that there is no way that they shipped me a broken one. They also seemed convinced that the hard drive would work with my model. Is there anything other than the hard drive, or logic board that could cause this type of problem? Is the hard drive ribbon the only other possibility? Is there something software wise that I can do?
Please. Any feedback or help would be greatly appreciated. I've spent more on this thing than I could have paid for a used, but working one, and I'm about to lose it.
Thanks!

UPDATE:
Ive installed the new hdd ribbon. It seems to have gotten me a little closer to solving my problem. I am now able to get into disk mode, and if I reset it, I can get to a screen telling me to connect my ipod to itunes and restore it. However, after the restore process, it says it's resetting the ipod, and then it goes right back to telling me that it needs to be restored. I've been trying to search all the forums on the "restore loop". It seems like a lot of people have had luck changing the drive letter. My problem is, that I can't get into the disk management window. When I try to click on it, I get the "program is not responding" and the window freezes until I close it. Again, I'm using windows Vista 64.
Any help would be GREATLY appreciated. I'll just try to keep trying, and keep looking around in the mean time.

Disabling Fusion Drive and Installing Windows on SSD of Late 2012 iMac

Hi, everyone. After a two-year wait, I'm ready to buy my first iMac (was waiting for USB 3.0). Before I get into my questions, I'll give you an overview of where I'm coming from so we can keep the discussion focused.
My Usage
I'm buying an Apple computer because it is the best-looking, quietist, and most powerful all-in-one computer I can find right now, but Windows is still my preferred operating system. I've used OS X before – it looks great and I'm sure it works great for a large number of people, but it's not for me. Windows works well and efficiently for me and I have thousands of dollars of design software for Windows. I'm not interested in a virtualization solution because of my performance needs. However, I do want to keep the OS X installation, if possible, for website testing and to play around with to learn the operating system better.
What I Want
I was attempting to buy the Late 2012 iMac last weekend, but it appears the BootCamp specifications and the Fusion Drive are currently limiting my usage needs. I'm configuring the top model iMac with the i7-3770 processor, 24GB RAM (8 default + 16 from Crucial), GTX 680MX, and the 3TB Fusion Drive. I don't actually want to use the Fusion Drive, though. I want Windows 7 64-bit and OS X 10.8 installed on the 128GB SSD and to use the 3TB hard drive as storage for my music, videos, photos, and documents.
My Questions
1. I've found a bunch of posts regarding installing Windows on the Fusion Drive, but they all seem to be about putting Windows on the slower 3TB hard drive portion and/or about trying to keep the Fusion setup after installing Windows. Does anyone have a walk-through for a new Mac user on how to break the Fusion Drive configuration and install Windows 7 and preferably OS X on just the SSD?
2. I've seen a bunch of posts debating about whether Windows can be installed natively using EFI to bypass the BootCamp limitations. Is this possible? The 21.5" version is running EFI version 2.0, so I can only assume the 27" would too, but it's not been added on the Apple website yet (http://support.apple.com/kb/HT1237). From what I understand, Windows requires at least version 2.0 to run in EFI mode. Also, if I am able to get this method to work, will I still be able to install the Windows drivers from the OS X installation USB (or do they even come with USB drives anymore?)?
3. If I have to use BootCamp, I assume I will have to split the 3TB drive into 1TB and 2TB partitions for BootCamp to see it (so Windows can see it). So I'd have Windows 7 and OS X on the SSD, and two storage partitions on the 3TB HDD that would show up as two drives for my files that both operating systems could access. Is this assumption correct?
4. I've seen posts about OS X automatically trying to rebuild the Fusion Drive. Let's say I'm able to get Windows installed on the SSD. Will OS X, or future updates to it, ruin my Windows installation? I would hate to do all this work and then have an Apple update corrupt everything.
I know this is a long post, but I don't want to spend over $3,000 until I can be sure I can make it work for me. Thanks to anyone who can help!
iMac, Windows 7

First, an advice: Boot Camp isn't compatible with 3 TB hard disks and Fusion Drive. For 3 TB hard disks, there's a workaround, but it doesn't work on a 3 TB Fusion Drive, so you won't be able to install Windows until Apple fixes this, so my advice is to wait until Apple launches OS X 10.8.3 or buy the iMac with a 1 or 2 TB hard disk and an external disk.
1. The SSD is used automatically by OS X to store the applications and data you most use, but Windows can't use it, and there's no workaround for this.
2. You can try to install Windows 8 in EFI mode, but I don't guarantee that it works. I tried it on my iMac and I started getting BSODs after some startups. Also, Macs don't use UEFI 2.0 (Macs use EFI 1.x), so you can't use Windows 8 advanced features such as Secure Boot. For Windows 7, you can't install it in EFI mode (it requires UEFI 2.0 or later)
3. Fusion Drive only allows you to have two volumes, and with Boot Camp, you can only have two volumes on your computer: one for OS X and the other one for Windows. That's because Boot Camp emulates a BIOS to make Windows run (although it isn't neccesary in Windows 8, if Apple would want).
4. First, you can't install Windows on the SSD. Then, OS X shouldn't ruin Windows because each operating system have got its space

3TB fusion drive and bootcamp

Hi everyone, I know there have be multiple posts on this, however I have a late 2013 iMac with OS X 10.9. I know Apple states support for bootcamp with a 3TB fusion drive from 10.8.3 fowards, however I wish to install Windows 8.1 pro from a full DVD using an external disk drive. All is good for partitioning and then when the mac reboots, it shows an apple (usual boot screen) and the a while after, it shows a "cannot do" sign that looks like (\).
Can anyone please tell me what I have done wrong or how to prevent this?
Thanks

Hi Chris:
I am afraid I can't help you, but I hope you can help me. I have been trying to install Win 7 using Boot camp assistant on my new iMac 27 (OS X 10.9) 1 TB HD and I haven't been able to get past the formatting. After 15 hours I still have a white screen, no Apple logo, or any indication that anything is running.
How long did it take you to format your 3 TB drive and what screen did you see when it was formatting? Did you also get a blank white screen?
Thanks.

Powerbooks, hard drives and Logic

Can anyone advise how to get more out of logic and my G4 1.67 powerbook with 1.5gig ram. I'm thinking to get an external drive - possibly a sata drive via cardbus. I'm sure I'd get better performance track countwise but I'm wondering if theres a way to improve performance of vitual instruments and logic generally by way of settings that utilise the drive. This possible? Any other tips welcome.

I have a travelling system that consists of a Mac 1.67 Ghz powerbook with 1.5 gb ram, a MOTU Ultralite and a 100 gb G Tech mini drive fw800 7200rpm.
I can get 1 instance of stylus rmx, 1 instance of trilogy, 1 string exs, a couple of pianos and a couple of synths like arturia minimoog or cs-80. Running 2 space reverbs and a couple of waves compressors.
With all of these running it is a little slow at times. But if you can't make a record with the above plugs then you're never going too.....
Ultralite kicks *** by the way!! I have a pro tools rig and a fireface 800 rig at home, and its up there as far as the quality of input.
Go and buy a g tech drive..they're around £220+vat which is quite expensive but worth every penny
Best of luck

Can I configure Mac Mini with Fusion drive AND a secondary internal 1tb HD?

I am about to order an new Mac Mini, and would like to have the speed of the new fusion drive, but would also like to have the option of adding a secondary internal 1TB hard drive.
I know I can add an external HD, but I really like the increased speed, and access times of an internal HD.
Secondly, since I am about to make this purchase, I am curious if there is any word on the street about any dramatic upgrades or changes to the Mini due to come out at the June conference, or in the fall?
Thanks for the input.
Mark

The only clue you really have about possible upgrades, is to look at the product cycle in the past.
The average product cycle for the Mac Mini is 381 days, the last upgrade was 209 days ago, so it's not very likely we'll see a major update in june.
you can look at product cycles of mac mini (and apple products in general) on this page:

keep in mind this is a website based on rumors, only Apple knows.
