StarTech.com USB 3.0 / eSATA 5-Bay Hot-Swap 2.5/3.5" SATA III Hard Drive Enclosure with UASP, 5-Bay SATA 6 Gbps Enclosure for HDD / SSD

I purchased this 5 bay eSATA / USB hot swap enclosure in October 2019 and now April 2020 the enclosure keep failing. It is not longer recognized by my NAS which I use for backups. I have to cycle the power in order for the NAS to recognize it again. During backups, the enclosure fails. I replaced the hard drives and still the problem exists.

I received this as a gift in december 2018. Since then the product worked flawlessly for a long period of time, until relatively recently. I started having issues when using it with a mac, and with nearly 2 TB of data across 5 HDD's all my drives became corrupted and wouldnt mount. Not understanding what was happening and being a fixer I tried everything I could think to get this back online, even going as far to hook up a different power supply. The dock will corrupt any mac drive that is connected for me, and in windows I get a read/write speed of 34MB/s both ways (USB 2.0 speed) I havent tried the esata I just prefer options and have only used USB 3.0. This unit has huge issues on a 3.1 port, will not consistently stay mounted, has a garbage read/write, the power cable failed, and Ive tried other USB cables without luck. A firmware update has not changed the behavior. Im not sure how the device went from issue free to borderline useless and a risk to my data in 6 months, but I refuse to even bother with a warranty. Startech makes good products and I trusted them but my unit has really made me feel like I might as well have thrown away $200+. Not looking for compensation, as Ill find a way to fix this myself. Just wish to make other buyers aware this thing may act up, and if it does dont bother troubleshooting just straight up return it. Overall build is solid otherwise. Its a product I was in love with until maybe a month ago.
