1tb blue OS drive?

I have read mixed reviews of these drives being not very good for os drives?, Does anyone have an issue with them?, from what I read as the drive fills it will get slower? can anyone confirm this?

Thanks

WDFAN_69,

All hard drives will perform slower as more information is added, sectors degrade, and data becomes fragmented. For general-purpose computing, the WD Blue line should meet most demands. However, for power-computing or demanding applications such as gaming or graphic rendering, then I would recommend a WD Black.
