Trim Not Enabled According to HDS?

[WinningWith7]

I have a Samsung SSD 850 PRO 256G which i reccently connected to a Syba SATA III 4 Port PCI-e x2 Controller Card and I installed the latest drivers and re-installs Intel RST because it crashed after adding the PCI card. I noticed in the PCI card boot sequence it said "PassThru AHCI"

According to Hard Disk Sentinal my TRIM is not enabled, perhaps because of the Marvel controller, but i was under the impression that TRIM/GC etc was done on the controller/SSD level and the drives performance is only at 80%

According to Samsung Magician I am getting close to double the speed when connected to the card vs my native sate 2 ports and it says

Is it dangerous to use the SSD on this PCI card like by causing crashes or wearing out the driver far sooner? Should i just connect normal hard drives to it?

Thanks

Hi Winningwith7,

have a look at this tutorial, does show you how to enable TRIM, and further info

- TRIM
Type this cmd
fsutil behavior query DisableDeleteNotify

It will give you one of two results, either a 0 or a 1. A zero indicates that TRIM is enabled correctly, a one means that it is not. If you have a TRIM-compatible SSD, but find that Windows 7 hasn't enabled the command, you can easily do so by running this command:

fsutil behavior set DisableDeleteNotify 0
