Old Mac Pro

Mac OS X is inherently a Multi-User system, even when there is only one User account. All User files are stored in a predictable place.

/Users

- your-user-short-name

-- Desktop

-- Documents

-- Downloads

-- Movies

-- Music

-- Pictures

-- Public

- your wife's account

- your dog's account

- your other other account

The green WD incorporates energy saving features. Those can cause problems since the sometimes when the drive goes to sleep when not being used it fails to wakeup.

The Mac can Boot and Run from almost any attached drive, including External drives. There is no "special bay" or "special name" for the Boot Drive. You could easily have six bootable drives attached to your Mac and have no controversy over which one to boot from. Shuffling multiple bootable drives into different slots or moving them back and forth between External enclosures would have NO EFFECT on your Mac's ability to Boot up properly.

The Boot Drive is the one last specified in:

System Preferences > Startup Disk

But won't an internal boot drive in one of the SATA tray's be a whole lot better/faster than one on an external USB or FireWire connection?

Also since he's doing video he would benefit a lot by taking advantage of doing putting in multiple drives inside and setting them up as a RAID array - very much faster for doing video in a RAID compared to just about anything else. Can hardly ask for a nicer machine to do RAID in than one of these big Mac Pro desktop systems.

Maybe Lorenzo could post an image of System Information showing the disk layout of his Mac Pro (click on the Serial-ATA and USB parameters and do two screen shots). Also a screen shot of an Activity Monitor screen would give an ability to see what's taking up all his RAM (click on the Memory column so that it's sorted from most memory used at the top).

dot.com-

You are quite right about an Internal drive being faster.

I was trying to emphasize that the Mac was completely flexible in where the System comes from, and there was no "standard place" that was reserved. and that "extra"systems can sit in the machine without the slightest confusion.

I did not intend to advocate for using an External drive for anything in particular. In general, External Drives are not faster.

If you think you need 3TB then I would go with this 4TB, and some users opt to partition to force it to use the higher IO outer tracks.

You can do the same with multiple drives to achieve more. The new 6TB drive can deliver 220MB/sec, using 2-3 such drives will max out the bandwidth of the four internal drive bays.

Boot your system from the Samsung XP940 on a PCIe adapter (no driver, no firmware, no overhead, full OS X booting). And what you save in not using a controller (it does use a $24 adapter) get 256 or 512GB M.2 SSD. 1000MB/sec vs 125-220 for standard hdd (best case), twice as fast as SATA III 6G controllers (500MB/sec). Great for graphics or where speed helps. Great place for Aperture or Lightroom or even iPhoto library as well as system.

Super-charge your system.

Green will park the head, use variable or slower rpms, go to sleep at inappropriate times. Fine sometimes for backups.

I have no idea what you tried to do and what you cloned (system? data? a drive with both?)

you want to separate data and system onto different drives.

you wanted ? to combine two drives as an array (can't install to an array and would not help or be needed) for your projects.

Ideal boot drive is an SSD but we aren't there yet.

Most people use Option to temporarily boot from the "new" clone and test it out to insure it works before going into System Prefs : Startup Disk control panel and then making the new drive the default.

Then pull the old drive, that will be your safety net and backup.

Only do one thing at a time, have backup, move to the next change. Don't worry about Lion until you have whatever else working first.

Diagram?

#0: System - 250GB Samsung SSD

#1: Data A - 2TB projects and video edits

#2: Data B - 2TB output from video project

#3: Backup drive - small 100GB partition of spare system / 3TB TimeMachine backup

External USB1: Backup and spare TimeMachine drive

etc

Getting Mavericks on a 2,1 is something I have not done but lots have.

2006/2007 Mac Pro (1,1/2,1) and OS X Yosemite ( 1 2 3 4 5 6 ... Last Page)

I would if you have the $$ ($300) go for the 256GB blade SSD.

That will work wonders with system performance, whether system and apps and booting (seamless), or for anything that benefits from 1000MB/sec read, 900MB/sec write

Should not have any problem with Lightspeed

The Mac Pro 1,1 and 2,1 from 2006 and 2007 are limited to 10.7.5 as their latest Mac OS X.

If you are a developer or think like one, there are some unsupported hacks that can allow you to run later versions.

Otherwise, the best way to move forward is to buy a new(er) Mac Pro. I suggest you skip the 2008 model and look at 2009 (Mac Pro 4,1) or later.

Lower price on a 2009 2.93
