While we're on the subject ... I'll never get anywhere close to using 250GB. My current C drive is only about 30 gigs, and my current D drive for all my data that's backed up nightly is barely 1 gig. Is there a benefit to not using all of the SSD when I partition it (theoretically it should last longer shouldn't it?) or just split the drive into 2 equal partitions using all the drive?
A buddy of mine is the same way. I almost fell over when he asked for help migrating his data and I was able to put all his critical data on my Mushkin 32GB thumb drive!!!
Here's a snapshot of my workstation here at the Condo that I'm on right now.
I NEVER have enough room for my PORN!!!! I have around 31 TB of disk space and it's almost full!!
ROFLMAO!!!
Now to your SSD question, you will not need to leave any room for manual Over Provisioning. The name brand drives are shipping with the Over Provisioning already on them from what I've seen.
BUT....if you really don't need all the room on the drive then you could go ahead and allow 10% of your SSD unallocated for Over Provisioning. (I only left 8% for over provisioning since I wanted the space.)
From the NUMEROUS tests I've read through it will improve speed and longevity on paper. But in "MY" real world experience, "I" noticed NO DIFFERENCE is SPEED!!
Also, I found several tests that were done on SSD's that TORTURE tested 240GB MLC drives (One was the Samsung EVO.) 24/7 with heavy write and erase cycles.
The Evo was one of the longest lasting drives and according to the data collected the drive had done a workload equivalent to around 13.5 years of the average work load for a Desktop drive.
So, "I" personally have no FEAR of transferring data back and forth to a SSD for fear of shortening it's life. Most Mechanical drives, even Enterprise drives, should be changed out every 3 to 5 years just to be safe.
I have some OLD Crappy OCZ Vertex I and II drives still in use just for shits and giggles. I mean my Thumb drive are BIGGER than the 30GB and 60GB OCZ SSD's I have still running and that's been a little over 5 years now. They are working fine with no issues whatsoever other than their size and speed.
I now just use them to throw 1 or 2 BD movies on to stream around the home Network. lol
One last little "tip" about the SSD as your OS drive in Windows 7.....DO NOT allow your computer to SLEEP in device manager nor allow it to put the SSD in stand-by mode!! Let it put your Monitors to sleep but NOT your computer or OS drive!!
Yes, Yes....I know.....the NEWER SSD's should FINE. But I do NOT trust them!! LOL
Better safe than sorry in "my" book.
I remember going INSANE trying to figure out why my computer would lock up after going to sleep or stand-by mode when I first got the OCZ SSD's.
Just telling Device Manager to NEVER put the computer to sleep solved it.
Oh, and my OTHER Windows 7 Ultimate little QUIRK is that if I let the Task Bar Hide "and" let my monitors sleep the OS will sometimes lock-up.
So, I can EITHER let my monitors SLEEP "or" let the Task Bar Hide....but I can't have BOTH going on or I get random lock-ups. My Monitors sleep and my task bar does NOT hide anymore.
lol
Not that "you" will have to worry about it, but Win 7 likes to have like 8 to 10% of a drive's capacity FREE or it will give you the angry RED lines you see in my snapshot.
