Expand the memory of your NAS or computer with the QNAP TR-004. Because you put up to 4 SATA hard disks in the drawers of the TR-004, you are not bound to the number of slots on your QNAP NAS. This way you create up to 48 TB more storage space or a RAID setup of your choice. That is quite a few files and backups. You can also easily connect this expansion enclosure to your laptop or desktop via usb 3.0 type c. External storage space is particularly useful for laptops, because it does not fit large disks. Choose whether you want to use HDDs or SSDs and whether they are 2.5 or 3.5 inches.
