I have a "modern computer" (dual core, 2.4GHz, Win 10) running a project that I estimate will take 52 hours.
What world-changing data am I processing? None. Just doing a process as old as any type of disk drive - formatting a new device.
Only in this case it's a "2TB" MicroSD card for a Dell 3180 - the 11" display, almost-a-tablet Win 10 laptop. It's their education offering from several years ago and has a 64GB SSD (probably EMMC) that's soldered in and not easily replaced and NO SATA slot - although there is a solder pad configuration for a SATA connector.
Because there is so little space on the "C:" drive, I'll be using the MicroSD as primary drive for all types of storage. When I started the format yesterday (originally exFAT with 128Kb blocks, will be NTFS with 4Kb blocks) the write speed was about 10MBs. Divide 2TB by that speed and then divide that number by 3600 to convert seconds to hours and I got 51.8888 hours.
Good that I have a place that little laptop can sit plugged in and running hard for two+ days ;-)
Why bother with that kind of format change? I have a lot of reference files that are plain text and most of them less then 5KB. Lots of wasted space if a 5KB files takes up more than 25 times that much space on the disk, plus solid state drives (whether SSD or MicroSD or whatever) need to be kept at a usage level of less than 50% because any change to a file means the entire file is re-written and the solid state memory elements see a lot of write activity - and those writes have a finite limit. Only using half the drive's capacity ensures the usage is evenly spread across the drive. Will the drive be a little slower than if it had 128KB blocks? Possibly. However, the inherent limiting factor is the dual core, two thread processor so the difference in the drive speed probably won't be noticed.
What would most Win 10 users have done if the format progress bar didn't change in 10 minutes?
