Mac Specs By Capability Mac Storage Upgrade Compatibility Guide. Storage info — details on speed, dimensions, and hard drive and SSD interface specifics — for all G3 and later Macs are organized below by category. Some Macs have a hard drive or SSD that can be upgraded easily, others have storage that 'unofficially' can be upgraded with. For whatever reason, Apple hasn’t allowed you to enable TRIM (one of the best ways to maximize the life of your solid state drive) on third-part SSD drives. Now, you finally can, no third-party.
- TRIM can be considered a more efficient way of handling “garbage” and was introduced shortly after SSDs became available. The TRIM command allows the operating system to inform the SSD about regions where the data marked for deletion are stored, and after trimming the SSD won’t preserve the contents of the block when it writes new data to a page.
- The #1 SSD performance utility to enable Trim for your Mac. Enhance your Mac performance, monitor health and much more with the all-new Trim Enabler 4.
- If you bought a Mac with an SSD installed from the factory, then TRIM is enabled by default and you’re all set—nothing to worry about. If, on the other hand, you later added a third-party SSD to your system, then TRIM will be disabled by default. If you aren’t sure, the best thing to do is double-check. Step 1: Check TRIM.
Summary
Depending on your needs, you may need to enable or disable TRIM on your SSD. To check whether TRIM is on and enable/disable TRIM in Windows 10, you can use the related command lines or the freeware - EaseUS Data Recovery Wizard. Carry out the way best suited to your needs.
Quick steps how to check if trim is enabled:
- Step 1. Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin).
- Step 2. Type the command and press Enter: fsutil behavior query DisableDeleteNotify

What Is TRIM on SSD
TRIM on SSD (Solid-State Drive) is an ATA (Advanced Technology Attachment) command that enables the computer operating system to tell the SSD to erase data blocks when they are no longer in use. The TRIM command allows the SSD's controller to manage the storage space available more efficiently and greatly improve the speed of writing data to your SSD. Thus, the use of TRIM can improve the performance of your SSD and extend its lifespan.
When Do You Need to Enable or Disable TRIM on SSD
By default, TRIM is enabled on SSDs. But it happens that you accidentally disabled it via some third-party tool. To keep the peak performance of your SSD, you will need to check whether TRIM is enabled and then enable it again if it's not.
Although the use of TRIM ensures the high performance of your SSD, it eliminates the possibility of data recovery on your device because it completely erases the data blocks when you perform 'delete' operations. That's the reason why so many users want to disable TRIM to make their data recoverable.
Whether you want to check if TRIM is enabled, enable TRIM or disable TRIM, you will find the way to do it from the details below.
How to Enable or Disable TRIM on SSD in Windows 10
You can check and manage the TRIM function on your SSD with the help of Command Prompt or a third-party tool. Via Command Prompt, you need to enter the proper TRIM commands to check, enable or disable TRIM. While with the third-party software to be introduced, you can see directly whether TRIM is on from the software interface and enable or disable TRIM by toggling the button. Choose the way you prefer to apply.
Method 1. Manage TRIM on SSD via Command Prompt
If you are not sure about whether TRIM is in use, you can check if TRIM is enabled first.
To check if TRIM is on:
Step 1. Click the 'Start' button on your computer and type cmd.
Step 2. Right-click 'Command Prompt' and choose 'Run as administrator'.
Step 3. Enter the following command:
If the query result is DisableDeleteNotify = 0, the TRIM support is enabled on your SSD. If the output is DisableDeleteNotify = 1, TRIM is disabled currently on your device.
To enable TRIM on SSD with Command Prompt:
Step 1. Click the 'Start' button on your computer and type cmd.
Step 2. Right-click 'Command Prompt' and choose 'Run as administrator'.
Step 3. Enter the following command:
To disable TRIM on SSD with Command Prompt, replace '0' with '1' instead.
Method 2. Manage TRIM on SSD with EaseUS Software
If you want a more intuitive way to get things done, you can use the free data recovery software - EaseUS Data Recovery Wizard. Although EaseUS Data Recovery Wizard is developed for data recovery, you can also apply it to check if TRIM is enabled or to enable/disable TRIM on your SSD.
Step 1. Launch EaseUS Data Recovery Wizard. If you have an external SSD, connect it to your computer in advance.
Step 2. Click 'Can't find location' in the top-right corner.
Step 3. Now you can see whether TRIM is enabled on your SSD from the interface. To enable TRIM on your SSD, toggle the TRIM button right. To disable TRIM, toggle the button left instead.
The Bottom Line
Enabling TRIM ensures the excellent performance of SSDs. But once you get your data lost on your SSD with TRIM on, you will lose it forever. Disabling TRIM degrades your SSD performance. However, it gives chances for data recovery when you accidentally deleted files from your device. Each choice has its own advantages and disadvantages, you can determine whether to turn it on based on your priority.
Some SSD drives are crashing in Yosemite do to an issue with something called ‘TRIM’. Thankfully if you followed the method in my article entitled “How to speed up your mac with a Solid State SSD Drive” you will not have this problem. But if you have used an SSD that needs TRIM, read on to find out about the problem and how to fix it.
What is TRIM?
Trim is a command your computer gives to your SSD hard disk to tell it to delete a very small amount of data.
If you think of data as papers in a filing cabinet, to remove an empty page (if you were an old hard drive) you would need to take out an entire folder of papers, then find and remove one page, and then put back the entire folder. This is because spinning hard disks deal with huge chunks of data called blocks, which are like a folder, and they can’t deal with anything smaller than a block of data. They spin so fast and the blocks are so big that doing an entire folder at a time is the fastest way to do it.
With an SSD drive they are different and so it’s much faster to do it 1 page at a time. In fact it’s slow to deal with writing large chunks of data. TRIM is a command that allows an SSD drive to remove (delete) 1 page at a time instead of a whole folder at a time.
TRIM and no TRIM SSD’s
In order for TRIM to work the SSD must have ‘TRIM’ support, and the computer must have ‘TRIM’ support.
Some SDD’s are enabled to work with TRIM. Others have chosen to deal with deleting data in a different way. They have their own ‘filing’ system. So the computer says ‘delete this page’ and the SSD does it automatically. It’s a bit like having your own personal secretary to do your filing. For those SSD’s it’s actually better to keep TRIM turned off and leaving it all to the secretary, so to speak.
For example this is what OWC say about TRIM:
If you have an OWC SSD, though, you don’t need TRIM. The SandForce controller in our SSDs takes care of this “garbage collection  In fact, enabling TRIM could actually hurt the performance and reliability of your OWC SSD, rather than help it.
Apple and TRIM
Apple have not allowed TRIM support unless you have an Apple installed SSD Drive. That means if you want to install your own SSD into a mac, you have 2 options.
(1) Install an SSD that doesn’t need TRIM.
Here are some SSD’s that work better without TRIM:
– any SSD with a Sandforce controller.
– All OWC Mercury Drives. (read this)
– Crucial M4
– Samsung 840
(2) Use an SSD that needs TRIM but run a hack that turns on trim support in OS X.
Here are 2 such hacks:

Disaster in Yosemite!
Many people chose option 2, to use an SSD with TRIM and run the hack, but in Yosemite all TRIM enablers/hacks were disabled by Apple. Anyone who did this now found their SSD would not boot in Yosemite. Nasty move by Apple. This was a disaster! (Thankfully, in my SSD article I recommended to use drives that did not need a TRIM enabler.)
The Fix
#1 PREVENTION is the best cure: use a drive that doesn’t need TRIM.
#2 If you have a TRIM drive already, and use the TRIM hack, the writers of the TRIM enablers are trying to get around this.
Trim Support Mac
#3 If you don’t yet have Yosemite, grab a non-TRIM SSD and copy your data across to it before you upgrade to Yosemite.
