And here’s an example where the output media is an SD card:
rbthomas@nuc8:/media/rbthomas/99602c92-f887-4578-b6bc-39c91d49c43c/rbthomas$ dd
if=/dev/zero of=tempfile bs=1M count=1024
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 0.48058 s, 2.2 GB/s
You need to add the clause “oflag=sync” on your dd commands. Without it the
MB/s numbers are really just measuring how fast you can fill up the RAM cache
(for write) or scoop up data from the RAM cache (in the case of read).
Here’s an example from one of my machines with a SATA-III SSD and

Also, if the problem is in the time it takes to write the hibernation
data, then those 2 minutes should mostly be spent

There's no such thing.
They're both sized depending on your particular needs.

As long as the filesystem is properly aligned on a 4KB boundary, I don't
think there'll be any noticeable difference. I highly doubt this

How did you do that?

If 12GB is reasonable (I have no idea, I don’t use “hibernate” myself) here are
figures to input to the calculation:
SSD sustained write transfer rate is between 30 MB/sec and 120 MB/sec.
Closer to 30 MB/sec (or even slower) if it’s a USB-3 thumb drive (even less
than that if USB-2); closer to

Thank you.
What are you using for bulk storage? Your system
has to copy ~12 gigabytes into it. Do the math--is
