I purchased this enclosure to replace a 3-year-old Sabrent DS-4SSD enclosure that's connected to a Raspberry Pi which I'm using as a NAS. The Sabrent was still working great, but the fan was getting loud and not blowing much air any more; it wasn't that quiet to begin with, actually. Though that enclosure was trayless, that might be the only advantage over this one. This one is very well built. It's lightweight but still feels very solid. The fan is silent as advertised, and the installation is trivial. I'd highly recommend this enclosure to anyone in the market. In addition, the customer service is second-to-none! Every email I've sent to them, and I've had several questions before andafter purchase, has gotten an answer within a few hours.
Perhaps the only downside to this enclosure, as others who have also wanted to disable the sleep function have already noted, is the lack of clarity in doing so. For clarity, here are my instructions:
1. When you visit the Yottamaster downloads page, there are two downloads that look like they could do the job. They both might, but the one I ended up using after being instructed by Yottamaster customer service was the rar file, not the zip file: Sleep Time Setting - Firmware Update for FS4C3 FS5C3.rar. You may need 7Zip or similar to open this if your version of Windows doesn't yet have native rar support.
2. This package actually requires installation; you can't just update the firmware without installing the application. So, run the setup program inside the rar file.
3. You'll also need the firmware, the .bin file, inside the rar file. I copied it to my desktop for easy retrieval later.
4. Very important: you must have a drive in the enclosure before you update the firmware. Otherwise, Windows won't detect it, nor will the firmware application. Customer service suggested I back up the drive before doing this, too, just to be safe. Once the drive is installed, connect the enclosure to power and to your computer's USB port. Make sure you connect the cable to the "main" port and not the "hub" port on the enclosure.
5. Now, open the application that you installed, VL715MPTool. A little pop-up should come up showing that the enclosure is connected. If it doesn't, it didn't detect your enclosure.
6. In the tool bar, click on settings.
7. In the settings window, click on open file in the firmware section. Navigate to the .bin file that you extracted from the .rar archive, and click open.
8. Back in the settings window, click OK.
9. Now, click the run or auto-run button. If you don't see the run button in the toolbar, you can find it in the functions menu off of the menu bar. Or you can just use the shortcut key: ctrl+a.
10. If all went well, the pop-up window should show that one update was attempted and one update passed. You can now close the application and begin using your Yottamaster enclosure without the drives going into sleep state.
