Topic: Solid State Hard Drives Questions?

Questo argomento è obsoleto e potrebbe contenere informazioni obsolete o errate.

My next purchase will be a small form factor PC, with a 250 gB Solid State HD, and a 750 gB 7200 rpm HD.

Question: What's the best way to arrange the filing structure for these two drives?
Do I put just the operating system on the Solid State?
Do I install other major programs in that same HD such as VDJ and my main Karaoke program?
Gonna need some advice on the best way to get the most out of this Solid State HD?

OS and programs on the SSD

Data (music & videos) on the HDD

Simple as that!

It's a two edge sword actually...
From one hand SSD provide extreme speed. From the other hand they have a "limit" when it comes to their capacity for writing data (write endurance) on the disk.

You would want to use the SSD for the OS. Since the PC boots from there and the OS loads from there, the operations would be much more faster and it wouldn't be too much to say that you would be able to log on Windows in less than 2-3 seconds after boot!
The only draw-back is that the same OS that's now 10 times faster needs to write files on this drive all the time (pagefile for instance)
The continuous write of data on a SSD reduces it's life. However for a typical consumer user the expected lifetime of a good SSD is more than 50 years!

Now, apart theory:
Yes you should install your OS and VirtualDj on the SSD (and every other application you need).
Perhaps you could also copy over mp3 files on your SSD if you wish... SSDs have no limits when it comes to reading data. However I wouldn't suggest you to do so. The extra speed you'll gain for reading a 10MB mp3 file does not justify the space charge on the drive. On SSDs, the more free space they have, the more their lifetime expands, since they can re-allocate the data from the physical cell that has been worn out enough to another free cell which has not been worn out that much.

I hope all these make sense. I tried my best to explain it as best as I could with my limited English!
 
Yeah, I have two laptops with SSD drives and the load times in VDJ aren't significantly faster than they would be for a mechanical drive.

Booting in to Windows 7 from cold in 13 seconds is cool though!

Keith, would that be because you are loading your files from a mechanical HD where THEY are stored?

Actually I can answer this question for you:
NO!
VDJ needs some time to load a file on a deck not because the read speed of the HDD is "slow", but because it deploys the file to RAM and analyzes it.

Let's say that for a very big file VDJ needs 10 seconds to completely load the song.
From these 10 seconds, 1 second is needed for the file to be read from the HDD, another 2 or 3 seconds are needed to deploy the song into RAM (decompress it onto RAM) and finally the rest of the time is needed for Waveform generation/audio analysis.

Now even if the time to read the file from the HDD goes down to 0 secs (because of the super duper ultra fast mach 6 SSD :P) you would still need 9 seconds of time instead of 10!

Practically you would achieve better loading speeds only with faster RAM or faster CPU, with faster RAM been the most important!
 
No, all the files are on the SSD drives. One PC is 128gb and the other is 256gb.

True. The advise is to set your virtual memory on the build-in HDD instead of the SSD. That way you'll reduce the write-actions to the SSD.
 
Or just delete the pagefile altogether. The pagefile was great in the "old" days but it's not needed now. One of the first things I do on any new PC (with a decent amount of RAM) is disable the pagefile.

How do I do this; In Windows 7?
 
My Computer > Properties > Advanced system settings > Performance settings > Advanced

Then select Virtual memory > Change

You can then disable it for the SSD, enable it for the HDD or remove it altogether.
