which SSD size needed

I have a newly installed system with 46,000,000 bytes (some 43 GB in Windows terms). Before i reisntalled it it was some 55 GB in size (it fluctuates daily). but i hope to keep it clean and lean to not go over 55,000,000 bytes(some 51 GB windows size). I don't plan to install large additional software (have Revit etc.). but also think with updates etc, the programs get larger and windows updates add space too.

Would a 64 GB SSD be large enough? I mean will I need to have spare space, and if yes how much? (I'm aware the SSD internally has spare NAND for cleaning etc., I mean do I need and how much additional spare space that is seen by the OS?). Like HDDS always need more for defragmentation. but with SSd i wonder if the spare NAND (that is not visible to the OS) already covers that.

I'm kind of eying the 64 GB Crucial SSD 300C. but if 64 GB is not big enough for the next 2-3 years, I go with the Intel 80 GB (but would wait on that one for the new generation). but regardless of timing and price, I still need to make a decision how much % more capacity I need than the OS+ installations likely will be.

Personally: if my current install had 43 gigs, I would be nervous about going with a 64 gig SSD.

You can delete the hibernation file to save a little--I think that file is equal to the amount of RAM?

I think a 43 gig install is larger than most. Mine is about 22 and has never been above 24. I'd be wondering why it was that large, but maybe you absolutely have to have all of it.

Have you rooted around looking for deletable stuff, temp files, etc?

I have 64 bit, Autodesk Revit, Autodesk AutoCAD etc. And thsoe are the applications that take forever to start and require the SSd the most. i have subscription and with every eyar they get bigger too, i guess.

43 gb is pretty huge. If I were you I would just use the 64 gig ssd only for windows and program files, turn off system restore and hibernation, regularly clean temp files including the "Software Distribution" folder under C:\windows\, keep data on another drive and image the system to another drive.

Updates shouldnt add significantly to occupied space. But i would look closely at my installed apps. Can you give us an idea of what programs you have installed, may be post a screenie of the Add/ remove programs window?

Do you have a Windows.old folder??

If so, it is a candidate for deletion.

what really makes it big is that everything possible is 64 bit, The CAD programs have several GB, Office 2010, Trane Trace, Microsoft Expression Studio. the rest are the small ones (microsoft security essentials, CD burner etc.,browser etc.) since I newly installed, I really don't have bloatware (and i always make complete install with formatting). I think i disable hibernation but will look when I'm at home. Besides disabling, do i need to do more to gain that space? i allocated around 6 GB for restore points and likely want to keep restore functions. I could try to reduce my virtual memory (have 8 GB), but some applications need that regardless of how much RAM you have.

when i was a student i used Maple and Matlab.. but don't think I ever need that again.

i formatted before installing. but will look anyway.

so, i was playing with moving the virtual memory to put it on another partition, which screwed up my system. Since my image with Macrium didn't work I'm re-installing. this gives me the opportunity to watch the size.

I installed the full 64-bit Professional version, installed ccleaner, Defraggler and Firefox. right now I'm installing all W7 updates. Nothing esle so far. I did not see a " windows.old" folder, I also had formatted when the W7 disk asked me.

the virgin setting for restore points is 6.25 GB max. For virtual memory it is "automatically manage..." and currently allocated says 7932 MB. (Have 8 GB of RAM).

According to Defraggler It currently uses 22.8 GB (24,532,705,280 bytes), which matches what the explorer tells me. From googling it sounds like it should be more in the 10-15 GB range. any ideas what i could change? I don't think I want to reduce restore points too much. I'm planning on reducing virtual memory to a set amount of 1 GB or so (since some software really need them regardless of RAM). any other ideas?

Assuming virtual memory and restore points use space, it doesn't sound too much, though.
