Speed of Working Between Two Internal Hard Drives

I have two identical internal hard drives, the hard drive in slot-A is the boot drive and contains all my applications, the drive in slot-B contains all my work files (Photoshop and Illustrator files, Word and Excel, digitized video, etc).
My question is, how much lag time is there with me working in an application on drive-A with the files from drive-B; if any? Is it better to have the work files on the same drive, such as if I moved them all over to drive-A?
Thanks.

Going off the advice of the much more experienced guys like Hatter on this forum, the way you have it set up currently is much faster. They even have instructions for moving the user files onto the B drive. I haven't tried that yet, but my iTunes and iPhoto data files are there, and it really seems to help. Many posts on details for doing that in this forum, but I'll defer so as not to take a chance of forgetting some important step.

If you want to just disable the Server aspect, this should work for both Lion and Mountain Lion...

Managing two internal hard drives in a Macbook Pro

Upon reaching the storage limit of my internal 7200RPM 750GB SSHD, I replaced the optical drive with a 5400RPM 1TB SSHD.
The Macbook Pro in question is the top end early 2011 15" model running Yosemite.
The 750GB drive is where the user folder, applications, etc are stored.
The 1TB is where I store my music, photos and movies along with some other miscellaneous things.
I have noticed a significant decrease in battery performance since installing the second drive. I was expecting some decrease but not to the extent that I have experienced.
Itunes, Lightroom and FCPX all seem to work well with the second SSHD.
What are your experiences with two internal hard drives in your Macbook Pro?
How do you manage two internal hard drives?
Aside from replacing the SSHDs with SSDs, what are your thoughts and experiences with running RAID arrays?
Any performance tips that you can share for getting the most out of my setup (circumstantial and installing SSDs are out of the question for now)?

Start over. Partition the new drive and install Lion. Activate FileVault. Then restore from your backup.

How to manage two internal hard drives

I just got my new iMac 27" with two internal hard drives (256gb SSD and 1Tb). When I migrated from my old computer it moved everything to the SSD drive. Are there some instructions somewhere to manage this and move things to the proper drive and have the info show up in my PLACES section in finder?

When you get the 27"iMac with the SSD, OS X comes installed on the SSD; so the migration assistant would naturally move applications to the SSD, including the contents of your user folder.
If you want to copy or move files/folders to the 1TB SATA drive you can do this any time in the Finder. Just don't move the +/Applications, /Library, /System+ or /Users folders
Can't tell from your post what you want showing in Places, but you can put any folder in the Places section of the Finder - just drag the folder there and it will show up in Places. The items in Places are just references - you can add or delete them at any time; it doesn't affect the actual location of the folder(s).

I currently have a mbp with two internal hard drives ( took super drive out) which for a video editor like myself is a dream I can edit video anywhere, my question can I order a new mbp with 2 internal flash drives?

I currently have a mbp 2.3 gighuz intel core 7 16 gig of ram with two internal hard drives ( took super drive out) which for a video editor like myself is a dream I can edit video anywhere, my question can I order a new mbp with 2 internal flash drives?

I wouldn't think so because the newer ones with Retina displays don't have an internal SuperDrive that can be replaced. Therefore the newer logic boards wouldn't have the two SATA/SATA Express connections on the logic board.
At least that was the case as of 2012. I've seen newer ones and they also don't have a SuperDrive.

Problems getting static NAT to work between two internal lans

Hi, I'm trying the old problem of routing between two internal LANs. This on cli 8.6(1)2. I have three interfaces/LANs; outside is to the internet, inside is the rack in the datacentre and office is a dedicated ethernet link to our office. What I want to do is allow all (for now) traffic betrween office and inside. There's a million hits on this on the 'net but I can't get it to work. Packet trace shows packets accepted from office to inside but blocked from inside to office. Both static nats are set up identically. Here's the output of show nat after packet traces in both directions. It clearly shows that inside to office isn't hitting the nat policy. I enclose what I think are the relevant bits of my config. Full config less passwords + crypto attached.
Manual NAT Policies (Section 1)
1 (office) to (inside) source static inside-office inside-office   destination static inside-ld5 inside-ld5 no-proxy-arp route-lookup
    translate_hits = 0, untranslate_hits = 3
2 (inside) to (office) source static inside-ld5 inside-ld5   destination static inside-office inside-office no-proxy-arp route-lookup
    translate_hits = 0, untranslate_hits = 0
interface GigabitEthernet0/0

same-security-traffic permit intra-interface
nat (office,inside) source static inside-office inside-office destination static inside-ld5 inside-ld5 no-proxy-arp route-lookup
nat (inside,office) source static inside-ld5 inside-ld5 destination static inside-office inside-office no-proxy-arp route-lookup

Hi Kevin,
because your interfaces inside and office are in same security level and you have enabled same-security-traffic permit inter-interface, traffic should simply flow between this interfaces. So i think you don't need NAT between this two subnets if there is not other reason to do so.
Then you just configure ACL which will permit traffic you want between this LANs. In this case both netwroks are directly conneted so routing should work(instead of NAT).
Best Regards,
Jan

Will Time Machine back up two internal hard drives on the same computer?

Hi,
I'm running a Quicksilver G4 - the last of the dual booters - and I have two hard drives installed. One is an 80Gb carrying the OS, apps, and iMovie projects and photos.
The original 60Gb drive is still in there, and has the old OS9 and all my work on there, and my iTunes library.
I currently back up to a MyBook 500Gb firewire external drive. It's partioned into 3 sections. One for long term storage, not backed up. The other two hard drives are backed up completely in the other two partitions, using Retrospect.
Can I use Time Machine two back up these two drives, and what do I need to do to the partions?
I thought it best to ask first.

Thanks Ewan,
What I'd like to do is to abandon Retrospect and use Time Machine only for both the internal drives. The remaining part of the external drive just used for storage and not backing up, I'd like to leave how it is, I just drag and drop there.
On my partions, I've allowed 80Gb and 60Gb partitions, the same size as the drives, though neither drive is more than half full.
When you say I can change the disk volume for backup, do you mean that I have to give Time machine a seperate instruction and schedule for backup? That wouldn't be a problem.

S.M.A.R.T status failing on two internal hard drives at the same time.

Thanks for reading.
I have a Quicksilver, 733 mHz machine with 1g ram... the PROBLEM is that I have two identical 60 GB internal Maxtor HD's that have run wonderfully for many years... they just decided to tell Disk Utility that "this drive has reported a fatal hardware error to disk utility". And the S.M.A.R.T status is reported as failing- on BOTH drives. That is why I don't believe this... suffice to say, I backed up everything.
The only change that has occurred recently, is an upgrade to OS 10.4.10. In its current status, I cannont run first aid or reformat (which is what I was trying to do in the first place).
Any suggestions?

Alright, this thread is getting confusing! I am up and running again, though I am unable to start up at all on my main 17 inch apple studio display (old crt monitor). I switched to another old CRt (non-mac, and needs own external power) and it is starting up fine- faster than before actually. I went ahead and disconnected the disk without the operating system, and it didn't fix it, I then disconnected the disk with the operating system and this didn't fix it. I then reconnected both drives, took out the RAM and rebooted. Then shut down and restarted while clearing the PRAM. This didn't fix it. I then rebooted off of the restore/install disk and ran disk utility. It doesn't report any error messages and I am trying to run the repair. I will post the outcome.

I have a Mac Pro tower with two internal Hard Discs, each one 2TB. I purchased a 3TB Time Capsule. But it does not allow me to back up because it says there is not enough back up space available. Between the two HDs there are 3.3TBs. Can I daisy chain TC?

I have a Mac Pro tower (OSX version 10.6.3) with two internal Hard Drives, each one 2TB.
I purchased a 3TB Time Capsule. But cannot back up because it tells me there is not enough space.
I have more than 3Tbs to store to the new TC.
Can I daisy chain two TCs to store the 4TBs?
How can I back up only the internal HD that is already full, without backing up the other one?
How can I do back up using Time Machine to back up the 3.5Tbs?
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?

Can I daisy chain two TCs to store the 4TBs?
No, you cannot link to produce a single large partition.
But you can have two separate backup jobs.. and use each partition. That is hard on TM but you can easily get a different backup software for it.
How can I back up only the internal HD that is already full, without backing up the other one?
In TM you do a different setup and exclude the other drive.
But it is better to use an alternative software IMHO.
How can I do back up using Time Machine to back up the 3.5Tbs?
You would need to use a network drive of more than 4TB .. it would also take forever. This is just wrong way to do it. Although you can buy a NAS that will work with Time Machine and load it with disks 16TB is possible.. if you can get a second mortgage.. the fragile nature of TM on 3rd party devices.. would leave me in cold sweat if anything went wrong.
TM is excellent at keeping incremental backups of files that keep changing.. as such you should use TM to backup your OS disk and main user directory.. exclude all files and directories that never change. Back them up separately.
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?
Yes, that is a much better idea. You want to store photos safely and you want to store them in multiple places. If you have multiple TB of photos, dedicate a couple of disks to the backup. ie have at least two copies.. not in backup format.. in straight copy format if possible.. so you can keep one of the disks offsite.
I would be using your MacPro internal disk access, to place the disk onto sata bus and do the copy disk to disk direct. Or even buy esata card.. or sata to esata converter cable so you can use esata box. That will beat any other transfer speed except thunderbolt for which you would need third mortgage. (The MORT in mortgage is significant).
The great jurist Sir Edward Coke, who lived from 1552 to 1634, has explained why the term mortgage comes from the Old French words mort, "dead," and gage, "pledge." It seemed to him that it had to do with the doubtfulness of whether or not the mortgagor will pay the debt.

How do I transfer my iTunes music from one internal hard drive to another internal hard drive without having to locate every song?

So I have two internal hard drives in my laptop but the hard drive that my music is on is running out of space. I want to transfer my music from the smaller hard drive to the larger hard drive so my computer can run faster. If I do this I'm afraid I'm going to have to locate every song within the iTunes library. Is there a way around it so I won't have to go in my files and locate every song? Any help would be greatly appreciated!

Instead of moving the entire iTunes folder you can copy it, then do the Shift-launch trick to select the .itl file from its new location. If it works, then go back and delete the original location.
But maybe clarify your configuration ... specifically, is your "iTunes Library.itl" file currently on the same drive that your music files are stored on? Or, do you keep your .itl file on a separate drive than the native files? If the .itl file is on a separate drive right now, then moving or copying the music files over to be on the same drive can result in iTunes not knowing where your native files went. You can get around that using the Consolidate utility in iTunes, but that is not necessary if the .itl file lives with the music files.

TC not backing up both of my internal hard drives.

So I am having a frustrating issue with my TC setup. I have a mac mini that has two internal hard drives each one being 500 GB. My TC drive is 1 TB. When I go to time machine preferences and click options I do not have any of my internal drives in the exclude lists. In fact it says that the estimated size of full backup is 733.31 GB which seems to imply that TC would be backing up both internal drives to my one external TC drive.
The problem is when I enter time machine and click on my second internal hard drive all the files are greyed out. I can see them all there but can't do anthing with them because they are grey. This is not the case for the main system drive.
I refered to this thread https://discussions.apple.com/thread/2022065?threadID=2022065&tstart=0 and checked in the disk utility to see if all the drives were in the proper format. Indeed all my drives are formatted as Mac OS Extended (Journaled). At this point I have no idea why all the files in my second internal hard drive are greyed out when I enter TC. I would greatly appreciate any help with this issue.

Did you change something in the setup after the TM had been running for a while.. is it running Lion server still?
Look at E2 and E3 in Pondini. http://pondini.org/TM/Troubleshooting.html
Some of these kinds of things are really complex.
Are you running the widget as that might show what is happening. See A1 reference above.
Is enough of the TC hard disk used up to suggest the backups have been working.. ie if the estimated backup size is 733GB is at least that much disk space used. If not it could be that TM has already not got enough space to back up the second drive.. although it should spit out an error message.
I would strongly recommend you buy CCC or some other decent backup software, and create a full clone of the boot drive and full backup of the second drive .. you can plug in a 1TB USB drive.. and save it all. Then if something goes wrong you have the server up and running again immediately. (You may have already done this, in which case please excuse the comments).

Prevent internal hard drive from being unmounted?

I have an XServe with two internal hard drives. The second hard drive is just for data storage. I have a work colleague who needs to get on this server periodically, using Apple Remote Desktop, to connect via afp to a second server in order to copy data over. When he is finished, he disconnects the mounted afp volume.
If possible, I'd like to configure the internal drives on this server so they can't be unmounted from the Finder by mistake. (Right-Clicking, etc)
Is there a way to accomplish this?

changed Finder preference to not show hard drives on the desktop. a work around but resolves my issue.

How to move your library files from one internal hard drive to another

I have two internal hard drives on my computer, one 500GB SSD for games and other programs that require fast access, and one 2TB for more bulky items, like videos, music and back ups.
The problem is that my SSD is pretty much full because my iTunes library location defaults to the "my music" folder which is located on the SSD, I would like to move the location of the iTunes library files to my 2TB hard drive in order to free up some space on my SSD (about 100GB).
I have tried to set the destination of the library via the preferences in the extras tab but that just seems to copy the files rather than move them, so it still needs them on my solid state in order to play them.
Please if there is a solution to this problem could you tell me
Cheers

Close iTunes.
Move the ENTIRE iTunes folder from the current drive to it's new location.
While holding SHIFT launch iTunes.
Continue holding until iTunes prompts to create a new library or locate an existing library.
Select the option to locate and point iTunes to the new location of the iTunes folder.
