測試環境
NAS: DS916+
DSM: DSM 6.2 beta
DISK: Toshiba DT01ACA300 3TB HDD*3 (RAID5), tray#1 ssd 未使用.(預留日後測試用)
DS916+ NAS 的設計:
DS916+ 採用 N3710 CPU, 內建 SATA III SATA3 Port*2, 此台為 4bay NAS, 另外增加的 SATA III Port 是利用 Marvell SATA controller 達成, 拆了機器及查了一下 data sheet, 箭頭處即為 2 port SATA controller signel, 連接至 NAS SATA 背板.
看了一下背板的線路, DS916+ 的設計上, Tray#1/#2 是接至 Marvell SATA Controller, 而 Tray#3/#4 才是接到 N3710 CPU 原生 SATA Port*2.
hdparm 小測
hdparm 為一個方便的硬碟測速程式, 可以大略曉得硬碟和NAS 之間的傳輸效能, 可當做參考.
如下, Toshiba 3TB 硬碟是接在 Tray#2/3/4, 這 DT01ACA300 HDD 之前也在 DS918+/DS418 實測過, 以 hdparm 測出來的傳輸效能大約在 190MB/s 左右. 在此 DS916+ 結果也差不多.
