Sign in to your XDA account If you've been working with PCs for some time, there's a pretty good chance you have some older HDDs or SSDs just lying around. Now, you can always just use them as is, or level up your storage by building it into a DAS. Right now, you can grab this TerraMaster 4-bay model for just $161. What's a DAS? Well, this might all sound interesting, but you might be saying to yourself that you have no idea what a DAS (Direct-Attached Storage) is. The DAS is a storage enclosure that allows multiple drives to be installed. So, if you have a few lying around, you can combine them to make accessing and saving your data easier. This TerraMaster D4-320 model features four bays and provides compatibility with HDDs and SSDs. So, feel free to mix and match with any combination: 3.5-inch SATA HDD, 2.5-inch SATA HDD, or 2.5-inch SATA SSD. You can even put these drives into a RAID configuration if needed. The installation process of the drive is also tool-less, making it easier to swap out or add drives when needed. You also get a USB-C port on the rear, making it compatible with computers and other devices. If you want to elevate the experience, plug the DAS into a compatible router to get convenient network storage. Although a NAS offers more versatility, a DAS can be a great solution if you just need access to your files. You can even pair a DAS with a NAS later on. If this sounds like something you're looking for, grab the TerraMaster DAS for $161 while you can.
