Always test these before you deploy them on servers.
Then you'll also find the people who have no understanding of how to protect data, or the bathtub curve of failure, getting thumbs down for their "warnings"

LOUD!!
I tried to copy 3TB of data over an external USB enclosure and it took about 17 hrs (tested with sabrent and fideco enclosures w/ a fan). No small size files or documents Average speed was about 30MB/s. Range 15-70MB/sec during transfer.
Also, my drive was very quite during the transfer process. I only hear it when it's reading/seeking data. 0 bad sectors on extended surface or SMART scan
EDIT:
Nvn. I think the problem was my source hard drive (WD my passport), which caused slow transfer speeds. WD black external gives me 100MB/s and USB 3.0 flash drive about 180MB/s
In summary - I was really hesitant to buy this drive. I hate refurbished stuff and I know Seagate doesn't have a good track record. But so far I'm satisfied with the purchase. I realize this is still like winning the hard drive lottery and it could crap out on me tonight. So I plan on only using it for disposable and already backed up files.
For someone looking into hard drive enclosures - I recommend this one by Fideco

The fan helps keep the hard drive cool (<30°C) and enclosure is really quite while writing. HDD itself makes noise while seeking or reading, but nothing to do with the enclosure. It uses an ASmedia chip which is supposed to be more reliable.
I tried this one made my Sabrent, but it didn't keep it as cool. Temps were in 40-43° range. Fan is in bottom and blows air in, not out, which is a stupid design choice. Enclosure also made a weird low "munching" noise when reading/ writing. Also, it uses a Jmicron chip, which can cause issues.

copy 4TB worth of data over then shutdown. turn PC on the next day and the drive is not accessible Frown
now I hear the click even when there is no HDD activity or even connect to PC at precise interval.
shake the drive and can hear something moving inside. probably the head is not park completely.
I like the drive and price so requesting for replacement and will see if the replacement is any good.

When you want add a drive or drives to an existing storage pool you can only add drives of larger capacity than the smallest drive already in the pool. In my case, with a 4-bay DS-423+, I was blocked from adding 2 of these drives to a pre-existing storage pool of 2 16TB drives.
The interesting thing is that you can combine different size drives if you build the storage pool initially with one of the smallest drives you intend to use. So it is not that you can't combine different size drives, but you must do it in increasing size order--so plan ahead. I wish I had known about this limitation when I first set up the NAS.
Also, it doesn't mean I can't use the drives, but it means I have to set up a separate storage pool which is a major disadvantage from a storage capacity standpoint.
