Re: SSD Best practices



fixed

I wondered that too.
I thought that high usage logical access paths would be in main storage...
and then having the high usage physical data either in main storage or SSD would be the next target...


having said that...
we have seen benchmarks of SDD vs. HDD or having a mix.
But, has anyone done a benchmark of physical disk to main storage (SETOBJACC) versus setting the object to SDD?

if I would have, for example, 32GB main storage and 2TB of disk
What would be be better bang for the buck:

I could upgrade my main storage to 128GB or 256GB for the same price
I could get 512GB of SDD???

Third, is to use CHGLF to place most, if not all, of your logical files
onto SSD. Most applications use LFs to access the data, and this can
speed processing significantly while not requiring lots of space.

I'm really wondering how much benefit this would be. By implication,
the physical files would still be on the regular hard drives, and so
the system would still have to go to the regular hard drives to
retrieve the record data.
