OImaster Techkoo 4x2.5'' SATA HDD/SSD Mobile Rack, HotSwap Backplane Cage for 5.25-Inch Bay

Good communication from seller and good turn around for delivery (3-4 weeks roughly) considering Covid. The enclosure fits tight into my case but once its in its set. Although the housing and caddie trays for the 2.5 hdds are strong enough they are a tad plasticy and id imagine if you swapped out drives every day its going to break. Having said this I have removed many drives during testing and its holding up ok after 2 weeks, take care and be gentle when inserting the caddy and then push the clip into the slot fully in and you should be fine.I removed the smaller fan completely and put a slim noctua 120mm fan on the top of the enclosure (top bay is free so used 2nd spare 3.5 bay on pc) this way I get a much bigger air flow and much better silence for cooling my 2.5 hard drives, I just hinged them with cable ties.Given the price and its fairly strong enclosure I would recommend this to anyone it beats rest on price and performance.

A very good way to extend storage in a much more convenient way than mounting HDD's internally. Using a few relatively cheap 7200 RPM 2.5" drives you have an instant and easily accessible storage pool or RAID array.The trays do look a little flimsy until you add a drive when they do stiffen up. The final latching is positive and holds the drives connections in solidly.The SATA connectors need to be the non-latched types which is not a problem as you are unlikely to shift the rack and knock or pull out the connecters.The cooling fan seems to work well, the drives in my Teckoo rack are all running at around 25 C, the system HDD's are all hotter averaging 33 C.Overall very pleased with the device, does exactly what is says and at a very competitive price.
