Abstract :
This research is to find out which NAS performance is the best in handling file delivery
with RAID configuration, the methods needed in this test include transfer rate parameters,
CPU and Memory resource usage, and QoS which includes throughput, delay, and packet
loss by uploading and testing. download with variations in different file capacities. The
results showed that synology is better in the transfer rate parameters of both RAID
configurations, both upload and download, with the delivery of variations in file capacity
delivery with an average transfer rate of 116-118MBps, and xigmanas 97-118MBps. In the
resource usage parameter, the percentage of resource usage in both RAID configurations
with testing upload or download xigmanas is lower with CPU usage 22%, memory usage
1.4-1.5GB or 30%, compared to synology CPU 30-34%, with CPU usage memory 190-
201MB or about 42%. On the parameters of QoS throughput xigmanas 780-930Mbit/s, and
Synology >800Mbit/s (standard >75% very good) from both upload and download RAID
configurations. The average delay of both servers is 0.03ms (standard <150ms is very
good), and packetloss is 0 (standard 0% is very good) on both servers from upload and
download tests. QoS results from both servers are in very good category according to
TIPHON standards.
