QNAP TR-004 4 Bay Desktop NAS Expansion - Optional Use as a Direct-Attached Storage Device

Product Information

For myself i just power off my external tl-d400s. My nas is setup for 24/7 that never spins down, because my usage patterns would probly trigger spinups/downs too frequently, so my case it's probly not worth it. also i'm not aware if whether my own device can keep the tl-d400s in a spindown state when it's not even doing anything, so i just use the power off just to be sure. Note that I get read speeds ~150MB/s still under this configuration. A couple interesting tidbits. First, when I connect the unit directly to a Windows PC, I am able to write at ~100MB/s! What's very interesting is that at first, I would get slow write speeds ~40MB/s on the Windows PC. I enabled write caching in Windows for the device (I guess it defaulted off because it's external storage) and then I got the 100MB/s speeds I quoted above. It's like write cache is disabled on the NAS - however, I verified that in Control Panel -> System -> Hardware -> General tab, Enable Write Cache (EXT4 delay allocation) is enabled. I've also tried with and without Control Panel -> Network & File Services -> Win/Mac/NFS -> Microsoft Networking -> Advanced Options -> Enable Asynchronous I/O enabled. I also tried disabling the "Enable Write Cache." It seems like the combination that gives the best performance for the internal RAID is for Enable Write Cache to be enabled and Enable Asynchronous I/O to be disabled (which I believe is default config out of the box). Me too got the TR-004 with 4 x Ironwolf Pro (4TB) disks in a Raid 5 config (and the TVS-872xt) over 10gb Ethernet connection to my M1 MBP with pretty much the same speeds that you present here!

I haven't seen a solution in this thread, and I have the same issue since I have had the TR-004 in September. My configuration and use case are as follows: There are three drives in the TS-332X in RAID-5 but writes to those work great - ~300MB/s from PC to NAS. It seems only the TR-004 is affected. Drives can only be migrated from one TR-004U to another TR-004U. The files and data stored on drives moved to/from a NAS (or another device) will not be recognized. I then pulled a drive from the array, and got three very loud beeps and the status light blinking red.Second, when I perform a write operation against the drive, while I perform a read operation, the speed of the read drops to ~40MB/s while the write is around ~30-40MB/s. Seems like a pretty severe penalty that shouldn't be the case. The TR-004U can only be used as an individual storage pool or volume on the NAS. Its storage pool/volume cannot be combined into the connected NAS. NAS applications cannot be installed on the TR-004U.

When connected to a Windows 10 and configured in RAID 5 (formatted as HFS): read/write at 190MB/s - 200MB/s The TR-004 provides an alternative method for users to expand their NAS storage capacity. By connecting the TR-004 to their NAS and using the Storage & Snapshots Manager, users can easily configure and manage their storage expansion. The TR-004 supports a variety of QNAP NAS storage and file management functions, allowing users to build storage pools, find files with Qsirch and organize files with Qfiling. Function
