your 240GB SSD has 223GB.

This isn't a rant about the space lost to formatting, it's more a PSA to point out how I fell prey to "well 240GB is close enough to 256GB" and then realized how little I really was getting.

Better to get a 256GB drive so you have 240GB after formatting. I'd have a bit more room to breath.

That is all
 
Also, many 240GB SSDs have the same amount of flash as 256GB ones, just with more set aside for over provisioning. Which is good both for performance and longevity of the drive. Honestly, if you're that close to filling the drive that an extra 10-15 GiB matters to you, get a 512GB drive instead. A 90% full SSD won't perform wonderfully no matter what.

And yet you chose to name the thread - your 240GB SSD has 223GB, effectively announcing the subject is formatted disk size.

Space was not "lost to formatting". It wasn't there to begin with.

240GB = 240,000,000,000 bytes
240,000,000,000 bytes / (1024^3) = 223.52 GiB.

I was aware of this calculation, but not of this. Thanks!

Hm.

Well, mine was $40 so it's hard to fuss too much I guess...

Not many, ALL of consumer 240GB drives have 256GiB (yes, GiB) of raw flash onboard.

Did you "overprovision" the SSD with 10% of capacity? That would either rob you up front, or take more.

With the thought that I spent way too much on this "hobby" this year, and the additional thought that I didn't need to, I put a 256GB Sammy 840 in the most recent system -- for a boot/system disk. I had a spare 60GB Mushkin Chronos SSD, and a spare WD "Blue" SATA-III. I also had a 3-PC license for Primo-Cache, with two installations still available.

So I added the WD HDD and cached it with the Mushkin. Installed all or most of my games so far on the latter. Works great.

Lost due to formatting?

It use to be there was a thread on here like this once every week and someone would again have to explain the difference between GB and GiB.

honestly I must say I am very surprised that I did not know this. I know many things, many great and powerful things that many wise men would kill for

this is a most distressing oversight

I'd rather have access to all 256GB and deal with shrinking later. That extra 16GB can go to use right now to give extra free space to the controller to work with for purposes of wear leveling when the drive gets more full.

hm maybe it does on the lower level.

yeah it probably does.

also, neat idea on primo-cache

goodness. It seems like just about everybody can be a lifer these days.
