What customers say about "Features"
Synology DS918+ 8TB Desktop NAS
  • It has ability to transcode videos on the fly, with very little CPU overhead.
  • The dashboard also features real time tracking of network traffic, CPU/RAM usage, users and storage health which is awesome.
  • The CPU you might think its slow, but it keeps up with my 8Core UNRAI Setup in regards to what i need it to do.
  • Of course a faster quad CPU also helps with more memory.
  • The unit ships with an Intel Celetron J3455 CPU which is speedy enough for Plex video encoding, file sharing, DNS, and more.
QNAP TS-453Be 8TB Desktop NAS Solution
  • It handles all with very low CPU & RAM utilization.
  • Packed with lots of options — RAID configurations, 2 Nics capable of trunking, apps to make it a cloud, a VPN server.
  • Currently I’m running a set of disks of mixed brands in a RAID 5 configuration and the performance is still quite good internally.
  • Has RAID5 with storage pools and thin provisioning, RAID scrubbing/maint scheduler.
  • Ram usage was at 80% and CPU usage was at 50/60% constantly with only one hhd installed.

  • With power supply monitor and USB backup you’re already out.
  • Easy to setup on my home network. Great connectivity.
  • Just two LAN ports (I'd prefer 4).
QNAP TS-453Be 8TB Desktop NAS Solution
  • Using this at home since it supports 4K HDMI and Plex hardware accelerated streaming.
  • Most of the softwares are user friendly. Good conectivity.
  • Great connect. Good storage. Good memory. Fast speed.
  • Trying to access USB attached external storage will crash your files system and make your external drive unusable.
