# 巡檢派工機器估算 --- ## 硬碟估算 * 檔案規格 * 1080P / 30fps / 1分鐘 ~= 120MB * 一張圖片可壓縮至1MB左右 * 一個錄音檔 / 1分鐘 ~= 0.5MB * 2TB硬碟 * 2000000 / 120 = 16666個影片檔 * 2000000 / 1 = 2000000個圖檔 * 2000000 / 0.5 = 4000000個錄音檔 * 每個issue最多放3個影片檔的話 -> 16666/3 = 5555個issues (Worst case) * 看每個月估計幾個issue, 來決定可以撐多久 --- ###### tags: `survey`
