I have an SSD that is about three years old.  It has 8.5.3 and X3e on it.
Should I get an new SSD and load Windows 7 and Platinum on it?
It is not so much a sonar issue, as to whether it makes sense to get a newer SSD at this point?
I suppose I could always put in the old SSD if needed.
 
Just a thought.  Not sure if it is worth doing.  
 

Always install applications on the same drive as the OS.

I agree.  But that is not my question.  As long as I am loading Platinum - would it be ideal to update the SSD drive at this time that the Windows OS and Platinum are on?
The SSD is about 3 years old.
 
Just thought someone may have experience with this.
 

Platinum is really only a couple of hundred MB for the install as you already have all the stuff from x3e. If it's not a space issue I'd stick with what you have now and maybe use another SSD for samples. I don't think age of SSDs is an issue just the number of writes they've done.

If you do change to a new SSD then maybe it's worth imaging the drive you have now and just transfer the whole thing to the new drive. Unless you want or need a clean slate to start with and don't intend to use previous Sonar versions ever again. Don't forget though that X2 has VVocal and there might be some other things in the earlier versions. Just check before you go ahead.

Thanks.  I suspect my older SSD drive has slowed down over the last several years.  Perhaps because of writing little files on it over the years (I don't store to it, but using the internet or other activities can put items on the C drive.)
 
Also, it seems that the newer SSDs are probably just better.  What a pain though, to have to re-register Windows and other sample programs (Vienna, etc.)  Maybe the clone idea takes care of that.

Deswind : A new SSD samsung 850 pro on a clean updated Os... then installing the new update's is the best way to go standalone.. then you have the option on boot to select !
 
Keep you SSD firmware updated. befor you install !

If you are asking from a performance point of view, Google the model number of your old SSD and look at the max read/write transfer rate compared to a new disk.  Most modern SSDs will do read/write speed of 450 MB/s or faster.  Some older drives have much slower write speeds.
 
Also, check for the latest firmware on your SSD.  Some had major bugs in their early F/W revisions.
 
To be honest, I think you will find that new SSDs are bigger, cheaper and faster than when you bought your old one 3 years ago.  I would go for a new one.

Thanks - I do not look forward to reloading all the programs - BUT - when I am done - I am assuming I will be much happier.  I just need to dive in.  The Samsung Evo 850 seems the way to go.  Is 240 gb enough for an operating system, Sonar and just the operating systems of soft synths - or does the 500 GB provide a little extra operating performance?

240 is fine I prefer the Pro's ..as I said chk the firmware 1st befor installing.... and just look see at your old ssd support see what they did !
 
You wont beat a clean build !

If you feel that your currently installed OS is nice and clean and trouble free, you could always use "Paragon Migrate OS to SSD".  This takes care of the TRIM settings and partition alignment so that the SSD performs as it should as if the OS had been installed on the SSD originally. I've used this $20 tool and it's well worth the small outlay.  My current Sonar rig was converted from platter to SSD using it and I'm very happy with the result.
 
On the other hand, if your PC is a bit messy and clunky, a fresh install is always nice.
 
240 GB is enough for a dedicated DAW for the OS, Sonar installation and a number of softsynths.  But next time I will go 500 for the extra head-room.  My dedicated DAW's boot SSD is about 75% full at this point.
