In the old days when boot times were quick

When things work correctly with systemd boot seems quicker than it has been 
for a long time, especially with SSD.  Most of the Linux workstations I run 
have boot times comparable to MS-DOS.

If things go wrong with systemd then things can get very slow (90 second 
timeouts).  But that's a solvable problem.

You should be able to rescan the SCSI bus.  It's been a while since I used 
SCSI, but that functionality seemed to work well last time I tried it.

Good SSDs have been just over $100 for a few years now.  It used to be that 
120G SSDs were about $120 each, now 512G is getting cheap.

Thanks Russell,

I should look at an SSD for my system drive  I have a couple of new drives for my RAID.

At any rate, I rebooted enjoyed 2 x single malt and I scanned the image, and now I shall hit the sack.

Many thanks

Andrew
