Review: Use with Plex Server - I purchased two of these to be used with a Plex server running on a Mac Mini, one for the main server and one for offsite backup. I populated both of them with WD RED NAS drives and everything is working great. I am getting around 200 mb/s per second on each drive. Considering the WD website says that the drives are rated at 180 mb/s, these speeds are better than I had hoped. It was extremely easy to setup as well and the Mac recognized the device without any drivers needed. I popped in the first hard drive and named/formatted. Once done I did the next. I did this for all four drives. I just popped in the next drive while the device was still on. I did this so that the drive names on the main server and backup would not only be the same, but in the same spot in the device. I am not sure how you would know which drive was in which slot if you simply threw all the drives in and plugged it in. This approach would be fine for most people, but I need the backup setup the same as the main so I can swap drives when necessary. My experience so far has been great. Drives showed up instantly, no issues with naming/formatting, speeds are where they should be, and no fussing with drivers/software. The drives also seem to sleep while not in use, which I like from a power saving perspective. This is a 24/7 server and having the drives go to sleep is an added benefit if they are not in use. I have had no issues with them waking up as soon as needed. The device is mostly silent. You can hear a slight noise when the fans kick on, but no complaints on the sound. The build quality is nice as the device is made of metal, except that the trays that hold the drives are plastic. Would have been nice if these were metal, but if pushed in properly they should hold up fine. The box also came with stickers for labeling the drives and additional feet in case they come off. This isn't a big deal, but I found it to be an extra nicety.
Review: So far so good! Works right out of the box. Does not use any proprietary file system or encryption. - Disclaimer: I've only used this for two days. I was hesitant to get this at first. I saw on another brand (QNAP) that it stated "The files and data stored on drives moved to/from a NAS (or another device) will not be recognized." and I wasn't sure if that was specific to them or if it was that way all around. For my purposes, I wanted my drive to be able to be read in pretty much any system. If this broke or was damaged or stopped working, I wanted to be able to put my drives into something else and be able to read them - I didn't want the data to be only able to be read in this box. And this was the case! I have plugged three hard disks in, each one containing data, and it read each of them just fine. Plugging disks is as simple as popping them in the tray, popping the two plastic side pieces in (no screws needed, though you could use them instead of the plastic side pieces, if desired), and pushing it in the bay. That's it. Disks go in easy enough, but they are latched in there, and though they are easy enough to unlatch, they are firm enough that I don't see it possible to "accidentally" unlatch them. The bays are numbered 1-4 on the bottom. My suggestion is to name the enclosure (BackUp, Media, etc.) and then name each drive after their position in the enclosure (Backup_1 or Media_3) etc. This way you can easily tell in Explorer which drive is which, if you were wanting to remove one. I actually ordered a second one. The first one will be used as my primary storage device, plugged into my router (it has a USB port for an external drive). The second will be used as a backup of that. I currently have a variety of drives in it - from a new 18TB to a smaller 8TB, to a really tiny and old 500GB drive I had laying around. It read all of them just fine. The 500GB had much slower write speeds, obviously, but the two larger (and newer) drives were capable of 100-200MB/S speeds. I am very happy with this and I'm glad I bought it. I think I would have liked the option to be able to turn individual drives off, but it's not that big of a deal. So far that's my only complaint, and it's not really much of a complaint!

## Questions & Answers

**Q: Do all the drives need to be the same make and size.? is this a raid controller? or a 4 drive nas?**
A: The hard drives don't need to be the same make and size. This is a direct attached storage device, not a NAS.

**Q: The pictures show a raid sticker on the front of the enclosure. but this does not natively support raid, the slots are singles. is that misleading?**
A: Thank you for the question. The pictures will be updated.

**Q: so i know the fans that come built in are 80x80x25 but what interface do they use ie 3pin or 4pin or soldered to the pcb**
A: It is a 3 pin fan, but it's not your standard 3 pin connector.   Don't expect to buy a standard fan (ex. Noctua) and have it work with this enclosure.

**Q: Is there a certain hard drive (nas, computer, etc) that should be use or will any hard drive work?**
A: The hard drives without any raid info can be recognized by the D4-300. For new hard drive, you can refer to this HDD compatibility list for help: https://www.terra-master.com/us/compatibility/

### ⭐ Review
*by L***S on April 22, 2024*

As stated in the title, if you even breathe in the direction of the cable and the cable going into the USB port on the terramaster moves a little, it drops the connection. Unbelievable, very disappointed.
