ReadyNAS Ultra 6 Plus questions

Hello !

I am looking for more informations concerning the ReadyNAS Ultra 6/Plus.

Context : I plan to buy this NAS + 2 x 3To WD Red

  • I plan to start with two 3To WD Red, then up to four 3To drives, then to replace all six drives with 4To WD Red when available. Is this scenario possible ?
  • I own samsung TVs. Will I be able to stream HD mkv files ?

    Thank you for your answers !

    • I have an Ultra 6 plus.
      It is great, but I wish I had bought a Pro 6, it's marginally more expensive, but faster and has 2 more years warranty.
      You can progress up the storage ladder as you have planned, however you must think about how you will backup your data.
      There are some volume expansion limits you may encounter:
      You cannot expand more than 8 tb beyond initial volume size, in your case with your 3 tb disks you will encounter this if you have single redundancy when you add your fifth 3tb disk and/or when you start adding 4tb disks.
      You cannot expand beyond 16 tb, this you will encounter if you use 6 4tb disks with single redundancy.
      Both limits can be overcome with a factory default, but his will require you to restore from a backup.

      Dual redundancy is recommended with large capacity disks as there is a not insignificant risk of a second disk failure during resync after replacing a disk.

      Streaming is no problem over standard Ethernet, multiple hd streams can be maintained by the ultra 6 plus and pro 6.
      You will of course need a media player of some sort. I use Dune HD Smart D1 which is superb with uncompressed HD video including bluray. MKV should be no problem if you have he right player and network.

      BluRay video is compressed using H.264 High Profile or VC1; actually you will not find much uncompressed HD video out there. Uncompressed 1080p @ 24 frames per second takes over a gigabit/second of bandwidth, and a typical movie would require about 1 TB of space.
