Ugreen NASync DXP4800Plus 4-bay NAS Review

Crystalmark is a useful benchmark to measure the theoretical performance levels of various storage devices. We are using version 8.

Using the default CrystalDiskMark 8 benchmark via 10GbE the fastest 4K QD1 T1 speeds came in RAID 6 with a read figure of 40.45MB/s and writes at 36.76MB/s. At 2.5GbE the fastest read speed was with disks in a RAID 10 array at 18.05MB/s while the fastest write figure of 18.18MB/s came with the drives in a RAID 5 array.

Turning to the 4K QD32 T1 test the best performance came with the drives in a RAID 5 array with reads of 450MB/s and writes at 278MB/s. The NAS didn't handle this test too well when the disks were in a RAID 6 array with reads down at 243MB/s and writes even slower at 207MB/s. As with the QD1 T1 test at 10GbE, RAID 10 provided the fastest performance (275M/s reads, 233MB/s writes) at 2.5GbE.
