Should library be on its own drive?

Quick question since I just bought a G-Tech G-Speed Q drive; I am thinking about putting all my media(video, photos, music, etc) in one place so I can stop hooking up 10 different hard drives in a mess of wires each time I have a project to do. Is it ok to put my Aperture library on an external drive(G-Speed Q) with other media or does it cause archiving issues since I do a lot of touch ups on photos, etc?
Thanks,
Brian

The Library can be anywhere connected to your computer. Apple recommends against putting it on a NAS. I've run large Libraries over FW400 with only minor performance degradation.
So that's "can".
What's recommended is to put the Library on the drive with the fastest throughput on your system. Anything else will be slower.
Also recommended -- but this requires a bit of learning -- is to convert your Images' Masters from Managed to Referenced. Referenced Masters can be stored on slower drives with much less of a performance hit than you'll suffer putting your Library on a slower drive.
Since Referenced Masters are usually on a different drive than the Library (the standard set-up is to put the Library on your system drive and your Referenced Masters on an external drive), it is possible to open your Library in Aperture with your Referenced Masters off-line. (Aperture automatically brings them on-line whenever the volume on which they reside is available.) Images with off-line Masters cannot be adjusted, printed, or exported at full-size. You will still be able to edit the Images' metadata, however, and will have access to the large thumbnails Aperture keeps (they are called "Previews").
This system works very well for many, and especially for those with portable computers and/or small system drives.
You should read this page in the User Manual. As it says:
"Aperture lets you choose how you organize your photos on disk."

Having Aperture library on its own drive?

I'm wondering if it would be advantageous to move the Aperture library to its own drive. I currently have 2 different internal RAID 0 volumes. One of them is comprised of two WD Raptor drives and is my boot drive and contains my applications and Aperture library. The other drive contains (some of) the referenced files and my data. Given that I am a heavy Aperture user (350,000 referenced images in a 150gb library) I'm wondering if I wouldn't be better off having the library be the only thing on the Raptors. I'm guessing that with a library this big, disk fragmentation could be a major bottleneck, plus I would also gain some speed advantages by having my volume only be 50% full (instead of 75%).
Do you think I am making this overcomplicated for a small speed advantage, or I might I see significant gains?
thanks,
Dave

Hi both,
Firstly i typo'ed the RAID number (sorry but sounds like you realized).
Subjective / empirical results from my own tests with my needs in mind:
I've noticed small performance improvements moving from FW400 to eSATA externals but frankly with 8Mpix/24Mb files sizes for the RAW's it's not been a significant contribution to decision criteria for me. Moving from USB 2 to FW400 was significant, esp. for launching Aperture, importing and exporting. During editing/adjustments, FW400 was quite acceptable.
As for RAM, moving from 2.5Gb to 4.5Gb gained me some when I was also running PS CS3 and other apps. (Mail, Safari, MS Office 2004/Rosetta etc.). At 4.5Gb, I rarely run into much virtual memory paging. My suggestion is to launch Activity Monitor and just see how you are using RAM for your workload. More RAM will achieve nothing at all if no paging to disk is taking place.
Aperture is reasonably multi-threaded but import to some extent and export primarily are the best examples of where the extra cores add value. Once into image manipulation, my 4-cores tick along at idle for the most part and sadly I Activity Monitor doesn't show GPU performance. Maybe the X1900 G5 card is maxed out (likely) but I don't know. I did a test with 2 x graphics cards under Aperture v1.1 but it showed no improvement whatsoever. Unknown whether Aperture v2.x will multi-thread gpu calls but I think not .... possibly core image limitation in Leopard.

Should my operating system be on its own drive?

Hi,
I've heard some people say OS needs its own drive, but people on this forum are known to have said OS and programs together are okay.
So my question is, is it better to separate OS and programs, or are the benefits very slim?
Thanks!
Mr D

Photon,
I have run multi-SSD RAID 0 arrays on various workstations and servers since 2011. No, it is certainly not "mainstream" theory, yes, you loose the ability for SSD vendor utilities to do cool SSD stuff (utilities from Samsung, Intel, etc.), and lastly are SSD RAID 0 arrays fast, yes, they are fast indeed!
My workhouse x58 build from 2011 uses a 5x 64GB Crucial C300 array on a Areca controller for the OS/boot drive (1500 MB/s reads, 500 MB/s writes). And my new 8-core 2014 build uses a 8x 128GB Crucial M550 array partitioned with 250GB for OS/programs and the rest for scratch, swap, and a bit of work area (also on an Areca controller with 28 channels, 2800 MB/s reads and 2300 MB/s writes). Is this for everybody, I would not say "no", I would say "heck no"! Do realize that when you have a 28-port SAS/SATA controller (I have lots of hard drives too), that having lots of small SSDs can provide good bang-for-the-buck vs. single or dual large SSDs (512GB or 1TB SSDs are pricey). Price wise, the 8x Crucial drives cost me just under what a single 1TB Samsung 850 Pro is selling for today - expensive, but not so crazy considering the cost for an 8-core build and 64GB of RAM.
Finally, does a RAID 0 OS/programs drive help Premiere Pro performance?(this is an Adobe Premiere forum section) No, not really. Does it help some other applications, absolutely. Do all programs open quickly, yup. Does putting Adobe bridge "scratch" files on a big SSD RAID help, yes indeed! I am not using Lightroom, but suspect that is another application that would likely benefit from a large SSD array.
The best performing SSDs to do a RAID 0 with are the Intel 730 series drives, but those drives are still pretty pricey. The higher end Crucial drives (now being re-branded to Micron) really scale well with RAIDs. I've read good and bad things about using the 850 Pro drives for a RAID.

When should a subclass have its own fields and when should it use its super

When should a subclass have its own fields and when should it use its superclass' fields?
Hi, thank you for reading this post!
Let me use a specific example to ask my question.
public class BankAccount {
     private double accountBalance;
     public double getBalance() {
          return this.accountBalance;
public class SavingsAccount extends BankAccount {
     private double accountBalance;
     public double getBalance() {
          return this.accountBalance;
}In the bank account example, both BankAccount and SavingsAccount will have a method getBalance(). Therefore, they
both require a account balance field. My question is since getBalance() for both classes will perform the exact same
operation, when should I omit declaring the getBalance() method and the accountBalance field in the subclass, and
when should I include them?
My own thought is when we never have to instantiate a superclass object (e.g. an abstract class), then we place
common fields in the abstract superclass and have subclasses access these fields via protected getter/setters to
access the superclass' fields. This is the principle of reuse.
But when you do need to instantiate a superclass and the superclass does need to maintain its own fields, then
I would need to duplicate the accountBalance field and getBalance() method in the subclass.
Is my thinking correct or incorrect?
Thank you in advance for your help!
Eric

If SavingsAccount inherit BankAccount.getBalance()...getBalance() would return BankAccount's accountBalance. This is NOT the correct result we want.Actually, I think it's precisely what you want.
We want getBalance() to return BankAccount's accountBalance when we use a BankAccount object, and SavingsAccount's accountBalance when we use a SavingsAccount object.I seriously doubt that. I think you're confusing a BankAccount with a Customer, who can have more than one account.
In every system I've ever seen, a SavingsAccount IS-A BankAccount - that is to say, it's a genuine subtype. Now, it may well contain other fields ('interest'?) that a normal account wouldn't, but 'balance' ain't one of them.

Should OS be in its own partition on a 40G drive?

After fighting with constant kernel panics in strange places (i.e., quitting Safari, booting Finder) I've decided to do an erase and install from the original panther disc and do the upgrades back 10.4.11 to see if that solves the problems.
I've never partitioned my HD, but I'm wondering if there is a reason to put the system in its own partition. If so, how much of the 40G do I dedicate to it?
I am the only user, so I want everything at the shared level and only my music and work files on my user space.

As Malcolm says, don't partition. You have a relatively small drive and partitioning will cramp OSX which needs a lot of free disk space to run optimally. The only reason I can see to put OSX on its own partition is if you want to have multiple copies on a computer. The other reason to partition is for convenience in making backups but that's going beyond your immediate question.

Should Wireless be in its own MPLS VRF?

Hi,
I already have an answer I like on this one, "YES!".
Unfortunately I don't live in Mike-land while I'm at work. I need some reference architectures or authoritative security guides that explain why this is a best-practice, (at least where MPLS VRF's are available for use).
My short list of reasons is:
- More refined segementation
- Easier standardization practices and associated documentation for tier I/IIs support staffs
- Easier to trouble-shoot when route tables are differentiated, (wireless VRF's and wired VRF's)
- Easier to observe and isolate traffic, (at firewall or router) in case of security breach
...I could go on.
Any good documentation on this out there? I can't find much.
Any help appreciated,
M.

Installing Windows XP to its own drive - and install question

Am I able to install Windows on half of a formatted 500GB hard drive or do I have to install on entire drive?
I have already partitioned the drive with 2 partitions and want to install Windows on one of the partitions.
When Windows starts during installation, asked what drive I want to use (not the same screen where you choose the BootCamp partition - before that) and offers choices to delete partition or create one.
I have done this before - can't seem to remember what to do.
Thanks,
Don

Hi Don,
for the BootCamp Assistant to be able to partition an internal harddisk, it has to find the drive to be filled with one single volume using the 'Mac OS Extended (Journaled)' file system and the GPT (GUID Partition Table) as partition scheme.
If already partitioned with Disk Utility for example, the BootCamp Assistant usually refuses to 'touch' that harddisk.
Personally I would go with the 50:50 approach. At least that's what I have on my third HD.
I never tried XP only on a HD with my Mac Pro.
Later Windows versions like Vista and Windows 7 work very well as single installs.
But XP relys heavy on the EFI-to-BIOS emulation Apple uses for BootCamp.
And besides what's the point to have a big unused/unneeded amount of diskspace assigned to XP, when you can use the second partition on that HD for some OSX useage.

Stefan

Does Time machine need its own drive exclusively?

Hello,
I want to buy a thunderbolt duo drive from Western digital or use in my MBA. Is it possible to use this drive for time machine purpose as well as normal external drive for itunes and jpegs?
Does this work or does time machine an external drive exclusively?
Thanx in advance

Time Machine will eventually take up all the free space on the partition it's backing up to. In addition, having your backups on the same drive as the original data won't help when that drive fails.

How do you assign an InDesign server instance to its own drive?

I am working on optimizing the performance of our InDesign server and read about the possibility of assigning drives to the individual instances in the performance guide. Is there a configuration file or command-line argument for configuring the working drive for each server instance?

I am not sure about that. Do you mean that all I have to do is provide the interface <cc:attribute name="value" type="lvl1.lvl2.someClass"/> and when I run the method, the returned result will be written into the expression provided in "value"?

CD/DVD drive open on its own - Equium L40

Hi,
I have a Equium L40-10X laptop bought recently from Pc World. It's been working fine until recently my cd/dvd drive popped open on its own. I closed it and then about 10 minutes later it did it again. This happens every so often. After a bit of research I found out it could have been a spyware issue. Scanned, and removed all traces etc. Problem appeared to be gone, but alas, the drive once again popped open.
Recently the drive is not reading discs as well. It seems to work when it wants for any time between 10 seconds and an hour at a time. The things got a mind of its own....and when it's not working, the button to open the drive doesn??t seem to work. I have to use a paperclip to open the drive.
Either I have a haunted laptop or there's something wrong.
Has anyone had any experience of anything like this before or have any advice on what to do?
Thanks, Jon.

Hi mate
I didnt notice something like this before but I presume its a mechanical problem.
Dont think 3rd party software (program, spyware, virus, etc) could cause this issue.
Additionally you have said that the drive is not reading discs as well.
In such case I would recommend contacting the ASP in your country and to ask for the drive check and if necessary for an ODD drive replacement.
If the warranty is valid the replacement should be done for free.
Best regards

Splitting event into its own library

My main iPhoto library is growing to the point where it will barely fit on a DVD.
I'd like to split out the larger of the two events in this library into its own library.
I do have iPhoto Library Manager...
I'd like to know how to do this as I really should get around to making my periodic DVD backups.

Yeah, I did just that - but as for the actual move, I was momentarily stumped until I realized I just had to click and drag the event in question into the new library.
Done and done, now am "starting over" by moving all the pics previously tagged with keywords into new events.
I said it before and I'll say it again - I simply do not know why I was so hesitant to use iPhoto in the first place! It's far better than my old "folder tree" system.
Thanks for the big hint.

Thanks Kirk and Thomas....I did appear to have a kernel panic.   The contents of the panic are shown below.   I used disc permissions repair on the internal and external drives and all seem to be ok.     iPhoto is completely rebuilt and all is well there.    I use Time Machine and a dedicated hard drive for its contents.   Been using Macs since my original computer....a brand new Mac II.....this is a new experience.

Aperture library seems to grow on its own

I imported a large number of photos into the Aperture library from an external drive I used to back them up from my PC. I decided to do this instead of referencing them from the external drive. It was about 85G worth of data. When I was done it seemed in Finder that it took up approximately the same space - which made sense. On import Aperture chose its own collection of folders and projects - which is OK - but now that I am reorganizing the library seems to be growing even though I believe I am moving files - not copying them. It was a date structure because that is how it was in windows and I am breaking away from that so there are folders for years, but in each I am making projects for events or subject (then adding projects and folders in those as needed) - by moving them out of their original month project/folder. So I have a folder 2010 and if I highlight it I can see all of my photos from 2010. Under 2010 are projects and if I highlight them, the appropriate photos are shown. I assumed this was correct, but I now believe I have duplicates of all or most photos as when I look in finder properties my Aperture library is now 138.45 GB.
Any ideas on what I might have done? Any ideas how to correct this? I cannot see the photo files in finder as I could in Explorer on the PC, so I do not know which files may be duplicates or how to correct this.
Thanks -

Assuming you have the back up drive still full of the images, you can simply create a new library by depressing the 'Option' key while launching Aperture > Create New.. button. This would allow you to start over.
You could then import the images and wait a while (this might be a couple of hours depending on the amount of images) for Aperture to build all the previews. Once that is done, you can run the 'Get Info' command on the library package and see what the final size is.
As for moving vs. copying, see this part of the user guide:
http://documentation.apple.com/en/aperture/usermanual/#chapter=5%26section=14
Aperture uses previews to show you the image data with all current instructions applied to it so you can work with the image. These take up space and result in a larger amount of space because they are in addition to the original files (which are not touched other than to be read by the program to build - or render - the preview you will be working with).
You can control the size of the preview that is built by going to 'Aperture menu > Preferences... > Preview section'. Selecting a resolution size and quality will affect the overall space used by all the previews in Aperture. The default values are: Half Size and Quality = 8. The resolution listed that has an asterisk by it is your monitors resolution (if you have a corresponding monitor size with the list).
Note - I use 1920 x 1920 (my monitor resolution) and Quality = 8, since I can easily change the drives in my machine and therefore space is less of a consideration than say a notebook or iMac.
Deselecting 'New projects automatically generate previews' option in the same section will prevent Aperture from doing so and can keep the size of the library down. You can generate previews manually in the 'Photos > Update Preview (while holding down the 'Option' key ) - turns to 'Generate Preview'.
Thumbnails (which are 1024 x 1024) are always generated and cannot be controlled, but some people are happy to use these for general browsing and just generate a preview when they need it.
Aperture does use space, so you just need to decide how much you want to dedicate to it. The referenced image library scheme keeping the masters on an external drive and the library on the internal drive is used by many to work with space limitations.
Note - you can still view the contents of the Aperture library by Control+Click (right-click) on library package > Show Package Contents command. Beware though, as changing any files in the package can corrupt the library. Just viewing the files in Finder without any changes is okay if you are confident in that type of work on a computer.
Final note - as an example, with a 4 MB JPEG master file in my library, the preview is 733 KB at the settings I use (or about 18% of the original). This means that I could have 5 versions of the same image (plus the original master file) in the library. If I used just OS X and Photoshop, I would only get the original and one copy for the same price in space.

Should a family share an apple id, or does each phone need its own apple id?

Hello coachscott,
Thanks for using Apple Support Communities.
For more information on this, take a look at:

Can I share my Apple ID with someone else?
You shouldn't share your Apple ID account information with other people. Each person should have their own Apple ID.
Best of luck,
Mario

Should library be on its own drive?
