Do additional drives need to be trimmed separately?

Question

Solid State Drives

The operating system (windows) is on an SSD (120GB) and of course trim is enabled.
Additionally, it costs:
1. regular hdd (1TB) for files
2. second ssd (500GB). I plan to transfer everything to it
3. I connect an external SSD (500GB) via usb3 adapter. I connect the same disk to the Mac through the same adapter

USB-sata adapter


Questions:
1. Do you need trim only on the main disk or additional disks too?
2. the fact that trim is used by the main disk, does it affect the hdd, which is next to it?
3. Does the second ssd also use trim, or does it need to be configured separately somehow?
4. what about the SSD that is connected through an adapter?

3-4. The discs are new and I don't want to kill them out of stupidity.

Answer 1

No.

The discs are new and I don't want to kill them out of stupidity.

TRIM has no effect on this.
TRIM is a set of commands in the data-to-disk transfer interface. With the help of these commands, the file system tells the disk which files have been deleted, and accordingly, they no longer need to be stored, and the space they occupy can be freed up.
You need to understand that this is just information, a notification for the disk. It does not cause any changes to the disk.
Just reports information that the disk can use in the next garbage collection.
In all modern operating systems, in particular windows 8, 10, it is enabled by default, and you do not need to enable it additionally.
The main thing is to look at the disk connection interface. TRIM only works over AHCI or NVMe.
If your drive is connected via the IDE interface, it will not work. This point is relevant only for relatively old motherboards.
Actually, what is the use of TRIM -
If it does not work, then the disk will constantly be filled with data to the eyeballs, almost 100%.
You have deleted a large file - and the SSD will continue to store it because it does not know about it.
As a result, there will always be little free space on the disk for recording. And with each recording, the disk will first have to clear the space, and then write it down.
The result is slow disk operation.
If TRIM works, the disk will know about the files that you have deleted, and at the first opportunity it will clear the space they occupy.
The result - the disk will work as quickly as possible.
