TL-D800C 8 Bay Desktop JBOD Storage Enclosure with USB 3.2 Gen 2 Type-C Connectivity

QNAP did it with their TL-D800C. I just want the most obvious thing! I want some drive bays slapped on a fast USB plug. I don't want backup software, RAID, or anything. I use ZFS which is far better than RAID. And even software RAID is better now than hardware RAID. How hard can that be? Apparently nigh impossible! I tried Sabrient's and Yottamaster's, both total garbage. Sabrient's had no less than 10 soft power switches, which must be tickled after every reboot...I mean, nobody wants to run anything unattended, and everyone wants a lot of extra fiddling to power up, right? 🙄 Hello Captain Obvious! If I didn't want a drive powered on I wouldn't put the drive in! Obviously there was zero thought put into actual user experience. Yottamaster -- also a total failure. At least they didn't add a bunch of stupid power switches, but the drives kept getting checksum errors, retries, and dropping out. I have 8 drives, of various brands, various ages and sizes, all of which worked perfectly after I returned the Yottamster and put them in this QNAP unit. It was two units, so not a matter of a single defect. It was totally impossible to use and corrupted data. Apparently Yottamaster is terrible at testing. Oh, and the drive sleds often got stuck in the cheap chassis. Just throwing junk together hoping people won't return it. So thank you, QNAP! These actually work reliably. 10 Gb USB, screwless insertion, no soft power switches, decent price point, good (and quiet) fans, hot-swappable, no drivers. No extra junk to bypass like RAID logic or soft power switches. Works perfectly on FreeBSD 14 with ZFS.

When I bought this, I assumed it had built-in JBOD array capability like the TL-400. It does not. This just serves 8 disks independently over USB. So, in order to use this as an array, you have to use software RAID of some sort. This is my fault for not researching more before buying, but anyone else looking at this should be aware. Regardless, I was able to get all 8 disks to set up as a pool in Unraid using btrfs with different sized drives. I just needed to setup the profile to "single" to get all space allocated. I'm using this as a backup, so I don't need redundancy capability. Write transfer speed bounces somewhere between 150-300 MB/s, which I'm guessing is limited by the drive speeds I put in the array. All drives are mechanical 7200 RPM. USB is on a 3.2 gen 2 port on my server. I really only have two nitpicks with this unit. My old TL-400 worked with a USB-C to USB-C 3.2 cable. This unit will not function with one. You have to use a USB-C to USB-A 3.2 cable. My other gripe is to show the drives are spun down, the light above it flashes fast. This is the same behavior when the drive is actively reading/writing. So, it's difficult to tell if the drive is active or spun down. If the drive is spun up but idle, the light is solid. Beyond that, this box seems to run fine. Automatic fan is quiet and seems to do good enough job.

If you've been trying to find a way to attach a bunch of disks via USB to turn a machine into a NAS, this is the best product in this category and I've tried so many. TERRAMASTER, Yottamaster, Sabrent, OWC, you name it -- this thing is the only product I've found that checks all the checkboxes and is reliable even in the 8-bay size. From a perspective of using this with Proxmox or TrueNAS or Unraid: This is just a generic DAS. It shows up as 2 USB 3.2 generic hubs when it's empty. Each time when you insert a disk, a ASMedia UAS device corresponding to that disk shows up with USB ID 174c:55aa. It works just fine without any Linux UAS quirks. It also supports hot plug / hot un-plug on a per drive basis without disturbing any of the other bays. I've tried disks as big as 24TB and had no issues. You don't really need to run any of the Windows/Ubuntu/Linux tools -- it shipped with the latest firmware and just works out of the box. It also passes through each drive's model/SN correctly, as well as SMART stats via just smartctl. I left the fans at the Auto setting on the rear switch and it was pretty quiet. Of course with 28TB spinning drives you really don't want it in your face, the hard drive seek noise dominates any hint of fan noise from the enclosure. The DAS powers on and off automatically after a power failure. I know all of this doesn't sound like a lot, but trust me, over the course of 2 years I've bought 10 different cheaper DASes from other brands that claim to do these things. They all had deal breaking flaws. They either intermittently had data corruption (ZFS checksum errors), hangs, randomly lost the partition table for the drive until a power cycle, disks disappear off USB, or had an annoying power button per drive bay and no ability to automatically power everything on after power failure. It's refreshing to finally see something that works.

Un equipo eficiente y un precio accesible para la capacidad que tiene y compatibilidad para conectarse con casi cualquier NAS de ir tenga conexión de USB tipo A

Good product, We use it frequently and it works correctly.

こちらの電源を入れっぱなしにしていると、PCの立ち上がり時にすべてのHDDにアクセスしにいくので、起動にすごく時間がかかるようになります。 PCを起動してからこのケースの電源をいれる必要があります。 対応しているHDD容量は18TBまでです。

ドライブをよく入れ替えて使うのでHDDケースとして使おうとMacSTUDIOにつないで使用してます。導入初日、数時間ごとにHDDがアンマウントされまう事案がありましたが、カスタマーサポートに連絡したらすぐに返事をいただき、即解決しました。ファンが大きいので低速回転で音が静かだし、電源内臓なので机上がすっきりします。 不満はユーティリティソフトの「QNAP JBOD Manager」のMacOS用がないことですね、ぜひ作って欲しいです。 追記：付属のUSBType-A→Type-Cのケーブルで接続する分には問題ないのですが、少しでも速い転送速度にしたくてType-C→Type-Cのケーブルで接続したんですが、数時間におきにHDDが順次アンマウントされるのです。相性の問題かと思って転送速度が高いUSB4対応ケーブルでAnkerとVCOMを3種類試しましたがいずれも結果は同じでした。Type-C→Type-C接続に対応してほしいです。

Tested with Windows 10, it works great, no issue at all. It give the SMART status of the drives which not very common with external enclosures. Big plus since you can tell before a drive dies and have a chance to salvage data before it's too late. My main con is that the QNAP software does not show what "letters" are on the disks so it takes more steps to know which is which when trying to find a specific disk to remove.
