Designed for professionals seeking high-speed, secure, and expandable direct-attached storage, it supports up to four 2.5" or 3.5" SATA drives and integrates seamlessly with Windows, macOS, Linux, and QNAP NAS systems.

## Description

Usb 3.0 and hardware RAID

Review: Was easy to set up, and configure - Got this at a good discounted price, and love it's design and functionality. Took a bit to get used to Web interface to set it up and configure initially, but caught on real quick. Running four drives, configured as (2) Raid 1's. So two Raids running side by side. Have it hooked up to my main Asustor NAS system, which sees the QNAP as two External Raid One's. With my Asustor NAS, mapping is easy, so uploading/download files between the QNAP Raids and my Desktop Computer drives has been easy, and file transfer speeds are adequate. Also like how the QNAP drives sleep when my NAS is inactive or off. Very Happy with this purchase. The easily removable drive bays are a plus and well designed, I like that they can lock, and the whole system appears high quality in design.
Review: Won't boot new drives w/o firmware update with old drive, not rack mountable without rails. - *Edited a week of troubleshooting later* Purchased new WD Red Pro 26TB drives (on their compatible list), unit still would not boot. Long story short: I had to dig out an old compatible drive 10TB to get the device to boot and then update firmware using their QNAP RAID Manager software in order for it to recognize newer drives. THE DEVICE WILL NOT BOOT TO ALLOW FIRMWARE UPDATE WITHOUT AN OLDER DRIVE INSTALLED. Horrible design. However, once it was updated, it functioned well. Just a very shortsighted design if you don't have older drives laying around to use to boot it in order to update it. Further, THIS IS NOT RACK MOUNTABLE UNLESS YOU HAVE RAILS. The included mounting ears only have one hole on each side, it is not rack mountable on it's own (I mean, you could, but with the weight of four drives you don't want to). What a crappy design. PERFORMANCE: Fine for an archive, WORTHLESS for multiple users/multitasking user. When doing one thing at a time, not bad. RAID 5 w/ 4x WD Red Pro's I'm writing around 200Mb/s, slightly less than their claimed performance but not bad. However, initiate a second task (opening another file while a transfer is going, try transferring to two different folders, even merely checking file properties on something else on the array) and it slams down to 10-15Mb/s until it can only worry about one thing again. This thing has pathetic multitasking performance. *Original Review* Unit is not compatible with WD Red Pro 22TB drives (but compatible with 16, 18, 20 and 24TB drives) - will not boot with a 22TB of the same family. Tech support, while polite and attempting to help, was in the end useless, defaulting back to "Choose drives from our compatibility list" - Well, how does your device not have compatibility with WD Red's? Completely mind boggling and has cost me a lot of lost money.

### ⭐⭐⭐⭐⭐ This has been great
*by K***N on November 24, 2024*

Works as expected with a raspberry pi 4. Wish it came with the appropriate rack rails. Beware this will delete existing data on the installed drives when you switch the config dip switch and press the set button. I'm using it in individual disk mode and haven't used the built in hardware raid.
