The problem was a faulty SATA cable. I got a replacement and everything is now working flawlessly.

Just my 5c, may have nothing to do with, just a wild guess. I have attached an encrypted USB harddisc with no OS to my MacPro. Every time I reboot, I need to press ALT for the boot dialogue, otherwise my MacPro is stuck within a white screen. When I detach the USB harddisc and reboot, no problem. So how about just detaching all peripherals and try booting ...

The "store files on a separate disk" advice is for many reasons, one of which is getting an extra read/write head into the process. As SSDs have no latency, and bus speeds are many times faster* than they used to be, the main reasons are mostly no longer valid. It's still a good idea for other reasons, but on a Mac Pro an external Thunderbolt drive won't ...

This worked perfectly for me on 10.10.3 (MBP early 2011): sudo pmset -a hibernatefile /Volumes/OtherVolume/sleepimage I created a path on the 2nd SSD to complete the above command "/Volumes/HD2/var/vm/sleepimage". I have my lidwake turned off so that I have to hit the spacebar to turn the comp on. This might have "helped" with the timing of things, but I ...

I've asked myself this question numerous times but keep coming back to the idea that the MacPro3,1 (a.k.a. 2008) still has a bit of life left in it. What is good: You can install 32GB of RAM in this thing for approximately $400 (price is average between two options on Amazon and assumes replacing all memory slots). You can replace the GPU with something ...

Based on personal experience, the 08 Mac Pro is well worth squeezing that last bit of life out of. It will take 64GB RAM, as 8 x 16 - even though Apple say it will only take 8GB sticks. Best source, other than OWC [which I think is US only] is eBay. There are specialists who sell old Mac parts & RAM; & mostly list with specific models items will run ...

A MacPro can hold a lot of RAM and in addition to the 4 HD bays and two Optical drive bays (that can be used with hard drives) there are two more SATA ports on the motherboard that are accessible with a bit of elbow grease. RAM is fairly cheap these days and unless you need terabytes of storage SSDs are not that expensive either. An SSD will give you a ...

I had the same "waiting for disk to reappear". it was the Hard Disk cable. it's easy to replace, once you take the HD out. Cable cost around $40 on ebay.

Installing Yosemite converted your hard drive to a Core Storage logical volume, and CS was only introduced in Lion (Wikipedia), so it makes sense that Snow Leopard would have no idea what to do with it. Here's how you undo CoreStorage (source - this method worked for me). It should be non-destructive, but as always, take a backup first! Also, note that any ...

Difficult to answer but: Do you see the CPU maxing out on the current computer (in the Activity monitor). As for the storage, it is something you can add later in form of supper fast Thunderbolt drive. You did not mention it, but adding RAM will take load from the CPU.


0

Only you can make the determination if paying the extra is worth it to you! Personally I always max out the RAM, processor and storage as I've always been able to utilize it all. I too program in several languages and run many virtual machines, sometimes three or four at the same time. IMO one can never have too much RAM, too fast a processor or too much ...

My personal recommendation would be not to move the OS to external drive as you would have to carry it around just to make the computer run. I recommend: Move all the files that you only need slow access to but are GB-eating to iCloud or similar network location. (For example: iTunes Library, Photos, Movies…) Get a Thunderbolt drive for applications that ...

I've seen exactly the same problem, and solved it with iDefrag, the partitioning tool needs contiguous space, not just space. The only other option is to wipe the drive. There are other defrag tools but they're not as good. I think iDefrag is the best available option (assuming you're using a standard HDD, don't defrag solid state drives)

If you exceed 20 GB of RAM (I would say also, if you exceed 8 GB of RAM), you're doing something wrong with your code / algorithm. So try to optimize it to achieve better performance and if you can't optimize, go for high parallelism (cloud computing). Moreover you can use you HD space as swap space for temporary store information. I would opt out for SSD ...

I've had a 960GB JetDrive 720 since September 2014 and have been running Yosemite since release. I found that enabling trim on Yosemite caused instabilities, and the system would lock up very regularly. I was in regular contact with Transcend about this for a while. I like to think that the removal of trim from the JetDrive toolbox on Yosemite was down to my ...

A traditional USB flash stick will not cut it for your purposes. This is not a question of R/W speed. Regardless of the R/W speeds (I own an excellent 128GB PNY Turbo stick), the on-board controller (the microchip that serves as the brains behind the drive’s operation) is built for low-cycle I/O operations. If you plan to run virtualization software from an ...

I'll go for the MBP SSD replacement because it'll not void any Apple warranty (as written in this thread and the last link to Apple warranty). In my case I'm working with a Samsung SSD 850 Pro 256GB and an external WD HD 500GB 5200rpm for Windows VMs. I'm using VMware Fusion and I'm not experiencing any kind of slow down or lag spike.

I would go with MacBook Pro for the better CPU, GPU (iris vs HD), and screen resolution since you are going to work with photo and video editing.


0

Go for the MacBook Pro. It'll handle better video editing and photo editing software, and it's more powerful speaking about CPU. It's built for professional worker and who need performance. Another good point is that you will be able to upgrade RAM and SSD in the future, which is not true for the MacBook Air (they are soldered). I've got a MBP 13" mid ...

Boot holding the option key and select the SSD to boot. You can also use system preferences to set it as the default boot drive. Once the machine will restart (or power on from off) and boot to the SSD, use Disk Utility to erase the HDD and enjoy your new Mac.

I have a mid-2007 Macbook that I upgraded to Lion, 4GB RAM, and a 256GB SSD. I was referred to Other World Computing by an Apple tech, recognized by Apple as an authorized parts vendor. If you have not upgraded to Lion, go ahead and do it and will the max upgrade in OS. I think it cost me to about $150.00 for the RAM and SSD upgrade. I know that 3GB RAM is ...

You are the best person to answer that. Use the Activity monitor and take a look at RAM and HD current usage. That will tell you what you need most. Usually the more RAM the better, that in turn also removes some load from the HD, but a fasted SSD could help in the initial step of loading the app in to the RAM. So if you open and close lost of apps and ...

Yes, it will work as they are the same type SSD between those two models.

I currently use a maxed out 11" MacBook Air which gets 10+ hours out of browsing with Chrome, with music playing from iTunes or YouTube most of the time. It can handle GIMP and Photoshop, video editing (tested with iMovie) and development with Xcode, Eclipse, Komodo and Brackets. I have experienced no problems with running games on High graphics settings ...

SSD's have been found to be quite durable. That article goes into depth with respect to SSD issues, and they performed hardware tests upon several manufacture of SSD.

As johnfinn68 answered in this Apple Discussions post: To determine [the bus speed of HDD and SuperDrive slots], go to the apple icon, about this mac, more info,select Serial ATA, then look at the (on mine) Nvidia AHCI and see the Link Speed and Negotiated Link speed.

I've got a Samsung 840 Pro with the Inateck USB 3.0 enclosure with UASP support. Runs great. Make sure you get the enclosure with DC power in. Some says it's not needed, but I do notice a slight difference with the DC power in.

Apparently RAM I installed months ago didn't want to play nice with the new SDD. Switching back to the old ram got the computer to boot no problem. (Weird, because I previously had no issues with the RAM before upgrading the SDD)

You might want to try the software "disktester." It has a recondition function that apparently works with SSDs. I haven't yet tried it myself, but it looks pretty legit.

Had the same issue. The installation can be sped up by deleting files stored in /usr/local/bin. (by rm -rf /usr/local/bin in Terminal app) It went even faster for me by using a USB stick with OS X and erasing the disk before installation. For USB stick (need stick > 8GB) see: https://support.apple.com/kb/HT201372 After reboot press alt then select the USB ...

Yes, there's a way to install OS X on the SSD. It's called "install OS X on the Fusion Drive." The Fusion Drive automatically puts the most frequently-used files on the SSD. When there are vital system files that your hard drive needs to access in its every waking moment, there's really no reason why the Fusion Drive would ever demote it to the HDD.


1

Short answer is no. Fusion drive has its own algorithm to determine which individual file goes to which drive, based on frequency of access. It doesn't offer any interface to configure the location of files. Moreover, it doesn't even list out which file belongs to which drive. In fact, the only way to know where a file is, is to read the file while the user ...

Yes, it is possible to replace the optical drive with hard drive / SSD. You can follow this guide.
