Hi all, I'm looking at upgrading my workstation by adding a couple SSDs as system disks. I'm going to keep my regular drives (reconfigure them) so that they are used for storage, backups etc. I've been reading some reviews on newegg.com and there are a lot of postings about the drives gone

War story In the '80s and '90s mainframes had storage, lots of it for the time. There was consistantly a problem with how to best use 'fast storage'. We found the best was 1) RAM - as much of it as you can afford 2) SSD - yes we had them then and they were expensive (and lost storage when

I ran virtual systems on mainframes back when. There was a neat thing they did then was to basically NOT do virtual memory on the 'client OS'. The 'client OS' could figure out it was being run as a virtual machine, and through special communications (called Diag back when) would tell the host OS

Sounds like you used VM370. With IBM VM370 using a OS/VS1 guest, there were several interesting options. I found that disabling paging on OS/VS1 gave me much better performance. Another thing was print OS/VS2 solved some of those issues and enhanced paging and swapping greatly. spooling.
