I upgraded several Macbooks with Samsung SSDs. But they were EVO 840. Here is what I noted for myself: SDD had to be plugged instead of the original HDD. Plugging in instead of DVD gives issues. The connector is very hard to plug and unplug to Samsung SSDs. It is much easier with Apple HDD. So you have to press firm to plug in the SSD. To unplug, gently ...

Honestly, it is a waste not to have an SSD as an internal drive in a MacBook (or any computer in general), you will understand it once you have one. Of course, the speed of your internal drive has absolutely nothing to do with that of external ones. The latter is only governed by the respective bus speed they are connected to.

Using internal SSD will make your system faster overall, including access to peripherals. With that said, you might or might not notice the access speed change to external HDD. That would depend how busy the resources was/is. System will still use the RAM as means to communicate between the disks. Assuming you have no bottleneck there, next possible slow ...

In your case probably a upgrade to SATA 3 SSD (internal) would do the most. AFIK your model supports it, and you will get up to 6 Gb/s R/W speeds and combined with RAM upgrade would get you what you want. Adding a external drive to expand the storage if needed, the one would use the Thunderbolt SSD. Find out if your Model supports the SATA 3 SSD before ...

https://github.com/Temptin/Documents/blob/master/Yosemite_Patchless_TRIM.md Brings forward the method of enabling TRIM using 'trimforce' in the command line. It does EXACTLY what Apple's official TRIM enabler will do with 10.0.4, without disabling Kext. Does Trim enabler give anything more for $10? I might be missing something.

Sadly for you, lots goes on in storage. Apple has several caching and thinning features that will proactively reclaim space when you run low. Unfortunately, you'll likely need to maintain more like 15 GB of free space if you wish to surf on the wave Apple has set for you. To solve this, you'll need to be specific about how you are measuring free space and ...

diskutil cs revert turns off the Core Storage volume manager for that volume. The Yosemite installer turns it on in case it's needed later (mostly for FileVault), but if you don't actually need it (e.g. for FileVault a Fusion disk) it doesn't do anything useful. If you aren't using FileVault or a Fusion disk, what Core Storage mostly does is confuse Disk ...

128Gb is plenty, with the condition it it is only plenty if you do not have much media (pictures, music, video). I have set up plenty of company laptops with 128Gb SSD drives, none are in any danger of running out of space. If you have media, and can offload it to an external drive , then you are still fine. iTunes and Photos both allow the media library to ...

I think no, as reported here in this guide for replacing the SSD only the SSD or Fusion Drive version has the M.2 slot: Use this guide to replace the SSD stick in an SSD only, or Fusion Drive model of the Mac Mini Late 2014. By the way you can easily figure out this opening the enclosure on the bottom following the guide linked before.

You have to format the SSD without using it as your primary disk. If you're able to run Mac with the old disk, connect the SSD via external enclosure and format it (or make a clone of the running HDD). After this swap the disks, boot form installer and install OS on SSD.

Fundamentally the SMART data of your 2013 Macbook Air SSD is normal comparing it with my Apple SSD SD0128F (inside a Fusion drive). Probably some attribute names (namely Unexpected Power Loss Count and Program Fail Count Chip) provided by your SMART app are false: Using two different SMART utilities here, the ID# 174 has the attribute name Host_Reads_MiB ...

Posting this from my working OS! The problem was with selecting encryption when formatting the drive. I reformatted without, painstakingly downloaded Lion again and all seems to be working fine now.

That means that the computer can't find a boot image. Power off and then boot with option held down. If any bootable volumes are connected, you can choose them. If no bootable volumes are connected, make one (internet recovery or use another Mac) and then connect it.

There is no software utility to check if a cable is defective. your symptoms are odd and could point to an issue with NVRAM that booting into the boot selector allows you to force EFI to pick a boot device manually. I would zap the PRAM (boot holding COMMAND, OPTION, P, R) and let it bong three times. Failing that try resetting the SMC (power off the Mac, ...

As a followup, I updated my 2011 MacBook Pro (not my Mac Pro) using an aftermarket SSD in December of 2014. Drive Selection Balancing budget vs performance vs reputation, I chose a Crucial M500 480GB — not a known high-performer, but with a decent reputation for reliability. I’m not sure the power loss protection capacitors are needed in a laptop, but I ...

So, I installed OS X EL Capitan, (10.11) and i started to transfer a 9Gigs app (xCode) to install it, and I had NO freeze, so it is Yosemite, and fixed in OS X El Capitan :) It was only a quick test but On Yosemite doing this froze the system every minute. If I get one freeze during the next days I'l Edit this post. If not I resolve it. Anyway, thank you ...

As stated above, this is a known bug issue. However, booting to the recovery partition (CMD + R while booting up) or by holding down Option to boot to a USB recovery drive (for those of us with home-brew FusionDrives who haven't gotten around to setting up a Recovery partition again), the process seems to complete without issue.

I do not why, but the Telegram App could be the cause since it is flooding your Console log with problems. The second one is the Fantastical app. I recommend you either fix those apps or disable them. U P D A T E Thank your for the logs. As said you have many 3d party apps that are not behaving and creating a lost of errors. For example the Fantastical ...

Yes. Some applications won't allow you to install them on drives that don't contain an OS X installation, however there are often ways to do it manually post-installation if that is the configuration you wish. Some applications will indeed do some writing to the internal SSD, since presumably that's where OS X is installed. The Library folders for example ...

1) Yes. Some applications may require that there be an operating system present on the the external drive, however. 2/3) Entirely depend upon whether you are booting from the external SSD (in which case an OS must be installed). If so, then all R/W operations will occur on the external drive. No I/O activity will occur on the internal drive unless you ...
