### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Not able to test yet...
  

*by M***Y on Reviewed in the United Kingdom on 11 December 2020*

you would think between buying a qnap and a drive bay you would be provided the screws to mount the drive bay to the nas, that's not the case, both the qnap and this qnap bay product include screws for 2.5", however the bay mounts using 3.5 flathead screws which are not provided, and 99% of pc's / chasis come with non-flathead 3.5 or 2.5 which can't be used in the qnap (they won't fit), so... I have to order screws and just stare at the bay until they arrive... small things make a big difference...I'll update the review once screws arrive and i can actually use it in the qnap nas.

### ⭐ 1.0 out of 5 stars







  
  
    Disappointing
  

*by B***E on Reviewed in the United Kingdom on 4 September 2020*

Despite this coming from the US and being quoted 3 weeks for delivery, it actually arrived in less than a week. However, that is the only positive news. Having bought this to put 2 WD RED SSDs in RAID1 (and save a slot in the 453D in the process), the minute I slotted the caddy into the 453D, it instantly switched off. Not shutdown - off. Tried a different bay - same problem. Removed the disks (to rule out the fact that one of the SSDs may have now developed a fault) and tried again - same problem. Tried an SSD on its own - fine. Tried a HDD on its own - also fine. Disappointing.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Simple to add to QNAP NAS... but
  

*by M***H on Reviewed in the United Kingdom on 3 February 2022*

It does not come with the larger countersunk screws to mount it in the NAS!  Plenty of screws provided for mounting the 2.5" drives though.Aside from the mounting issue, it's not a bad unit and is immediately recognised and easily configured in QTS 5.
