Synology DS1522+ 25+ Review: Real

I wanted to expand my Synology SHR raid by adding 1 new drive. I followed their instructions; but 2 days after installing the device, I noticed in the GUI that I was at less than 20% finished checking parity.

近幾日把汰換下來的Synology 918+給老家用， 也順便把老家的舊Nas原有的10T*3 Raid 5放進918+， 以上都順利的完成了 ~~ 雙11剛好撿到一顆便宜的10T硬碟，就把它放到918+內， 想說把Raid 5轉成 Raid 6，也可以多容錯一顆， 結果按下開始轉換的時候，我嚇到了...

Recently I decided to put together my first NAS. In planning it out I decided to go with RAID 6 for the parity drives but was very concerned about the performance. All the RAID calculators online showed that RAID 6 would get a decent Read gain, but no Wri

If I were to start all over and set these drives in RAID-6, how much performance do you think I would get? My dd command line benchmarks show that the volume throughput is about 670 MB/sec currently.
