The time needed to prepare a USB Pen Drive and to use it on a thin client depends on many factors, being the most important:
In the table below you can find some information obtained using a medium quality USB 2 Pen Drive. The smaller the image file, the less the time to prepare the USB Pen Drive. The faster the USB Pen Drive writing speed, the less the time to prepare the USB Pen Drive.
| O.S. and Thin Client model |
Image Size | Time to prepare the USB Pen Drive using the Toolkit and a factory image saved on the PC (see How to create Recovery USB Key for Windows Embedded) |
Time to prepare the USB Pen Drive cloning a device on itself (see Cloning a Windows Embedded device using a USB Key) |
Time to restore the image on the thin client |
More time needed by O.S. to prepare itself (Windows reseal) |
|---|---|---|---|---|---|
| WES7 (C9700) | 8 GB | about 10 min. | about 18 min. | about 14 min. | about 6 min. (using PRAIM factory image) about 7 min. (using a cloned image) |
| WES8 (U9084) | 16 GB | about 19 min. | about 36 min. | about 17 min. | about 5 min. (using PRAIM factory image) about 8 min. (using a cloned image) |
| Windows 10 IoT (N9012) |
64 GB with 50 GB free space | about 8 min. | about 36 min. | about 15 min. | about 14 min (using PRAIM factory image)about 10 min. (using a cloned image) |
How you can see doubling the image file size will:
Probably a half size image file will half the time needed to write it on the USB Pen Drive.
For WES7 and WES8, the Windows reseal phase is shorter if the PRAIM factory image is used; that is because using a cloned image requires an extra reboot of the thin client. For Windows 10 IoT instead, this phase will require many reboots and this will take longer.
