This hard drive tray is a perfect replacement tray for the TS-459 and TS-869 Pro QNAP devices

Arrived promptly, part works just as advertised.

TS-569 Pro perfect fit

I'm using these in a QNAP TS-563 because the factory drive trays didn't have adequate ventilation.

These trays come with 2 keys, 2 different sets of screws and a clear plastic like coating where the drive mounts to reduced seeking noise and to shield the drives from shorting out.

Overall these drive trays are very well

Perfect and as described.

These keys with the tray were $15 and had free shipping

Very glad I didn't lose another drive in the set, as it's now rebuilt and in good health

RAID 5 worked and saved all my data (for the critics out there, I do run a backup to a USB external drive for all the irreplaceable data - family photos etc, but it would be a pain to restore everything from the backup unless it was absolutely necessary)
