Ugreen NASync DXP4800Plus 4-bay NAS Review

To test real-life file/folder performance we use a number of different file/folder combinations to test the read and write performance of the NAS device. Using the FastCopy utility to get an MB/s and time taken for each transfer, the data is written from and read back to a 2TB Seagate FireCuda 510 NVMe SSD.

• Windows 10 backup – 118GB.
• Data file – 100GB.
• BluRay Movie – 42GB.
• Windows 11 iso – 5.4GB.
• File folder – 50GB – 28,523 files.
• Steam folder – 222GB (8 games: Alien Isolation, Battlefield 4, BioShock Infinite, Crysis 3, Grand Theft Auto V, Shadow Of Mordor, Skyrim, The Witcher3 Wild Hunt).
• Movie demos 8K – 21GB – (11 demos).
• Raw Movie Clips 4K – 16GB – (9 MP4V files).
• Movie folder – 12GB – 15 files – (8 @ .MKV, 4 @ .MOV, 3 @ MP4).
• Photo Folder – 10GB – 304 files – (171 @ .RAW, 105 @ JPG, 21 @ .CR2, 5 @ .DNG).
• Audio Folder – 10GB – 1,483 files – (1479 @ MP3, 4 @ .FLAC files).
• Single large image – 5GB – 1.5bn pixel photo.
• 3D Printer File Folder – 4.25GB – (166 files – 105 @ .STL, 38 @ .FBX, 11 @ .blend, 5 @ .lwo, 4 @ .OBJ, 3@ .3ds).
• AutoCAD File Folder – 1.5GB (80 files – 60 @ .DWG and 20 @.DXF).

The fastest write transfer we saw from the DXP4800Plus when dealing with the larger files was 606MB/s using a 10GbE connection with the drives in a RAID 0 array, dealing with the 5GB photo. With a 2.5GbE connection, the fastest write speed was 540MB/s for the Windows 11 iso transfer. When it came to reads the 5GB photo transfer was again in top spot with three of the arrays (RAID 0, RAID5 and RAID10) all over the 1GB/s mark.

When it came to writing smaller files, the fastest we saw using a 10GbE connection was the 3D Print folder (RAID 0) at 564MB/s. The second best was the 543MB/s from the AutoCAD folder transfer with the drives in a RAID 6 array. With a 2.5GbE connection, the faster writes (275MB/s) came from the Steam folder transfer using either RAID 0 or 5

As with writes the fastest read speed was from the 3D Print Folder (10GbE), this time at RAID 10, 900MB/s. In fact, there is only a 35MB/s spread between the arrays for this transfer from the slowest 865MB/s (RAID 0) to the RAID 10 figure.
