Re: SSD vs HDD

It has been proven time and time again that SSD is significantly faster.
Joel Spolsky from Fog Creek mentioned that all of his developers are on SSD
now and compile times have been reduced drastically because of it.

The only problem is that the cost is still much higher. I have been hearing
that people are using SSD for OS and applications and data is stored on a
HDD.

Lukas is right though, both should have been unjournalled for apples to
apples comparison.

Running some tests in Rochester MN on HDD (Hard Disk Drives) versus SSD
(Solid State Drives). On eight 280GB drives (405CD) INV901C ran for 4
hours and 58 minutes. On a three drive Raid 5 parity set composed of
SSD's it only ran for 1 hour and 57 minutes.

I think that's significant.

CST600C dropped from 78 minutes down to 30 minutes.

The files on HDD were journaled. The data on the SSD was not because we
had our journals and receivers back on *SYSASP and it didn't link them up
when we restored the library on the SSDs.
