asustor AS5202T 首款 Dual 2.5GbE NAS 开箱分享 (下)
Asustor AS5202T 首款 Dual 2.5GbE NAS 开箱分享pctine 楼主 #1 2019-05-29 01:50以 AJA system test tool 小测一下传输效能. 前面提及为了反应实际应用环境, 这里是使用 Seagate Ironwolf 4TB NAS 盘*2, 做 raid1(mirror) raid type, 而并非使用 SSD, 我想即使 SSD 价格愈来愈亲民, 但较多数人还是在 2bay NAS 上使用硬盘来取得更大的储存空间.
写入约在 145MB/s, 读取 185MB/s, 这大致符合预期, 因为写入的速度瓶颈是在硬盘的写入速度, 而 ironwolf 4TB hdd 读写大约就在 150MB/s 上下, 但读取速度明显超出硬盘的实际效能, 此处是因为在 Asustor raid1 模式下, 它采用了 parallel read 的加速模式, 会同时自两颗硬盘并行读取, 所以读取速度提升上来了
而前面提到 AS5202T 单一网口速率是 2.5Gbps, 理想的传输效能约在 250MB/s 上下, 此处实测低于此数值, 瓶颈是在 hdd 本身, 如果采用 ssd 则速率会整体提升上来.
如果以 iperf3 實測, 可以看出 AS5202T 網速趨近於 2.5GbE 理想值.
