[DUG] Solid State Drives

[Jason Coley]

I'd buy some more ram, at today's prices it is a good investment. And yes give the VM about 2Gb, I myself are now developing using a Mac 21" with 8Gb, and a VM using Parallels with Win7 x64 (4Gb ram) on a solid state drive.

I had a windows 7 system with 8Gb and the 64Gb solid state, and the new mac config is almost as fast.

I don't like the Mac OS, but I am learning XCode for a new project and I do like the Mac system, although I use a secondary screen and my MS Natural keyboard and Logitech mouse, mac keyboard and mouse were awful.

?Sort of similar config, except 32bit Windows 7 with 4GB Ram, and a VMware XP with D2007 and 1GB allocated.

I find the performance of the VMWare virtual PC the worst aspect of it - the XP virtual machine is really prone to triggering intense disk writes - which looks like Windows XP starting swapping in the virtual PC, and resuming and suspending the virtual PC gives about 3 minutes of solid disk activity that 
kills the PC until finished.   It almost looks like the virtual hard disk 
file is getting rewritten, and this triggers some kind of issue in the Windows 7 - the Windows 7 Resource Monitor shows the disk writes look to be to do with the VM hard disk file and the Windows 7 system volume information.

Anyone have any tips how this can be tuned better?

Most of the time its not Windows 7 running out of memory, as I keep an eye on this.

Also have to say that both the VM and Windows 7 have D2007 installed and the performance of D2007 under Windows 7 native is much better - eg in the VM there is often a delay on hitting  F9 before any compilation starts 
happening.   Should I be allocating more than 1GB, even though most of the 
time D2007 does not seem to use more than 200-300MB memory ?

for the last 2 years I've been using Vista 64 bit Quad Core with 8GB Ram, and Normal reasonably fast HDD's I run Delphi inside a VMware machine running XP 32bit, with 1.5GB ram allocated.

doing a full build of my main app is 953000 lines or so and takes 80seconds or so..


Just got a new machine with windows 7, running the Same virtual machine. but the Win 7 is using only solid state drives. 100GB and 220GB

Doing a full build is only 11 seconds..

Worth the money? Very much so.. Time savings over a day is quite large with the overall improvements
