Not too much things can trust . <| sep |> Actually it was Epstein flight log book that was used as evidence . <| sep |> I assume you mean no capacitive buttons ? The Google Pixel series , Sony Xperia X series and Huawei Honor 8 come to mind . <| sep |> I ' d like to point out that many serverlevel RAId controllers , such as HP SmartArray controllers store the Array definitions on the disks themselves , so that if the controller dies the job can be taken over by another SmartArray controller with the same interfaces . Some models have FLASH storage instead of batterybacked RAM for the Writeback cache . Drive sizes and all that . I ' d say that when you pass 600 GB HDD sizes , it ' s time to swap from RAID 5 to RAID 6 even if RAID 5 is otherwise considered ' good enough ' as rebuild time is getting too darn long . Also , when building a new , large array , or setting up a large SAN , it doesn ' t hurt to make certain the HDDs are from as many different production lots as possible . It REALLY sucks if they ' re all from the same ' sub par ' lot and all fails in rapid succession . Hot spare or not . is just as stupid a question as ' would you like to shoot yourself in the foot today ? '
