TRIM

Why is my Mac Air so slow?

Macbook Air

Episode 1636

Mark from Tustin, CA

Mark's Mac Air is slowing down and he wants to know if there's an app like SpinRite that can run them. Leo says that sold state drives (SSDs) use TRIM, or wear leveling to keep your SSD in good shape.  It doesn't need to be defragged directly. But it will trigger the controller to run the TRIM utility. Search for TRIM in macOS. But it should happen automatically. If your OS is older though, you may need a third-party app to do it. 

TRIMFORCE Enable is the command you can use in the terminal. That could speed it up.

Sean from Pennsylvania

Sean has a nine year old desktop loaded with software. Will he be able to get updates to Windows XP to end of life? Leo says there's a good chance of that. He just won't get anything through SP2.

How can I make my SSD run fast again?

Vertex 2 Solid State Drive by OCZ

Episode 1335

Paul from Del Mar, CA

Paul wants to know how to get his SSD to run as fast as it did when he first got it. Leo says that SSDs can slow down a little over time and there's a command called TRIM, which can fix it if his OS supports it. It's like garbage collection. If he runs a defrag on the SSD, it will force the drive to TRIM. Leo recommends he do this very rarely though, because it can affect the even wearing of the drive. Will it make it that much faster? Not really. It might help a little, but he'll have to decide if it's worth the trouble.

Why is my SSD running slowly?

OCZ SSD

Episode 1312

Michael from Fountain, CO

Michael bought an OCZ SSD to speed up his computer, and it's much faster than the SanDisk SSD. Leo says that's because of trim. SSDs don't have to be defragged, but with trim, they can accomplish something called "wear leveling." That way the SSD won't wear out prematurely due to an overused sector. It also allows it to be consistently faster. Without trim, SSDs tend to slow down over time. The good news is that trim is built into the OS now. He doesn't need AHCI, native command queuing, or hot swapping.

How can I use TRIM with OS X Yosemite?

SSD

Episode 1130

Dave from Buena Park, CA

Dave upgraded his MacBook Pro with a Samsung SSD and it was running TRIM. But OS X Yosemite has a new security requirement called Kext Signing, and it only allows drivers that are approved by Apple. Leo says he can download TRIM Enabler, but he does have to disable kext signing to use it. And that's dangerous because it could open the door for malware. TRIM is built into Yosemite, but it only works with Apple Hardware.

How can I speed up my Android phone?

Episode 1066

Sindar from Maryland

Sindar is having trouble with his Samsung Galaxy Note II running slow. Leo says that it's always a good idea to delete everything, and do a factory reset to see if that helps. Also, the more apps he has, the less storage he'll have available, and it will slow down more. The older a smartphone gets, the more worn the SSD gets, and the slower it becomes. That's why modern Android phones use a utilty called "Trim." It also may help to go with Android 4.3, because that provides Trim support.

Why is my data being written to my SSD and not the hard drive?

Episode 1031

Lisa from Downey, CA

Lisa get a new Dell computer with a 256GB SSD and a 2TB hard drive. Lately, it's been slowing down and she discovered that all the data has been written to the SSD and not the hard drive. Leo says that Lisa should make her spinning drive the "D" drive and then direct Windows to put all her data onto that D drive. She can move all her data over to it and then remove it from her C drive.

She'll need to right-click on my documents, click on "properties," then "location," then tell Windows where she wants the data to go. In this case, that will be the "D" drive.
