TRIM on external usb SSD

Eigil Krogh Sorensen 76 Reputation points

Microsoft Windows Version 22H2 (OS Build 22593.1)

I have attached a Crucial. CT1024MX200SSD1 SSD via usb.

Settings says this about the drive:
System > Storage > Disks & volumes > Crucial_ CT1024MX200SSD1
Name Crucial. CT1024MX200SSD1
Disk ID 3
Manufacturer Crucial-
Model CT1024MX200SSD1
Serial number
Media HDD
Bus type USB
Location Bus number 0, Target ID 0, LUN 0
Capacity 931 GB
Type Basic
Advanced Disk Properties

Thus Windows 11 treats the drive ad a HDD.

In the PC there is another Crucial_ SSD:
System > Storage > Disks & volumes > CT2000MX500SSD1
Name CT2000MX500SSD1
Disk ID 1
Model CT2000MX500SSD1
Serial number
Media SSD
Bus type RAID
Location Bus number 0, Target ID 3, LUN 0
Capacity 1,81 TB
Type Basic
Advanced Disk Properties

As can be seen Windows 11 treats that SSD as a SSD.

How do I enable TRIM on the Crucial. CT1024MX200SSD1 SSD connected via usb ?

    Hi EigilKroghSorensen-9377,

    TRIM ia a command not supported via USB. If Windows "Defragment and Optimize" detects your enclosure as SSD, you can use its OPTIMIZE function or resort to third-party software to force-trim manually or on schedule.

    Another option is to make a batch file with "defrag X: /L /U /V" (X is the letter of your SSD) and use it manually, or set up a schedule in Windows Scheduler.

    To create a .bat file, paste the defrag X: /L /U /V command into Notepad, hit 'File'->'Save As" and save it as trim.bat
    You can then use this file manually or set up on a schedule.

    On my systems, Windows 11 recognizes one USB SSD as an SSD and will perform the Trim function on it but will not perform the Trim function on a second USB connected SSD drive. Attempting to execute defrag X: /L /U /V returns an error that the function is not compatible with the drive.

    Windows only supports Trim for UAS (USB Attached SCSI) device.

    Use newer as possible as USB-SATA converter.
