這是先測試 NAS 內部實際的磁碟效能, 日後會再實測透過網卡傳輸, 依上述數據, 若採用 10GbE 網卡, 其效能約 1000MB/s, 表示若採用 SSDx4, 建立 RAID5, 已可完全滿足 10GbE 傳輸所需達到滿速, 當然如果加入更多的 Disk 組成RAID, 在效能上會再往上提升.

將 DS1621+ 上四顆 SATA SSD 組成的 RAID set, 直接移到 DS1621xs+ NAS 上,
將原本舊 NAS 上的硬碟, 直接移到新購 NAS 上, 保留原本所有的目錄檔案及帳號權限設定等, 這樣的移轉不管是因為 NAS 故障或是購買新機, 是很多人常在做的, Synology NAS 在做系統遷移上做的相當好, 而且這樣移轉所需時間也相當短, 不用十分鐘就全部完成了. 系統可以馬上重新上線.

可以看出 Synology DS1621xs+ 在讀取的效能上, 確實優於 DS1621+, 相對也對的起它的價格, 比 Synology DS1621+ 三年保固多了二年, DS1621xs+ 提供五年保固, 另外還提供次個工作日換修交換機服務.
有關 Synology SRS 換修服務可以參考官網.

DS1621+ 的前一代為 DS1618+ NAS, 也是自己家裡所使用的機型, 這幾年來使用的經驗一直很好, 它也認真的 全年不停機了好多年.
今天以相同的 RAID set 移至 DS1618+ 測試了一下. (Synology SSDx4 RAID5)

整體的效能表現, 可以發覺次一代的 DS1621+ 確實增強了非常多.

這台和DS1819+加購E10M20-T1=$35500 (8bay+2M2+10G)
和DS1621+加購E10G18-T1=31500 (6bay+2M2+10G)
兩台比較起來建議買哪台
建議購買 DS1621+, 這台效能比 DS1819+ 好很多, 但 6 bay vs 8 bay, 除非你的容量需求在 6bay NAS 上面無法滿足, 再考慮 DS1819+,
但另外一點 E10M20-T1 是為了前一代 NAS 所設計的 10G+SSD cache 複合卡, 以後的新機如 DS1621+ 大多會內建 M.2 socket, 表示 E10M20-T1 卡日後是無法在新機使用. 也無用武之地.
