How much usable space is on this SSD?

CrownedEmperor312 · Mar 30, 2015

Hi,
How much usable space is on this SSD (http://www.newegg.ca/Product/Product.aspx?Item=N82E16820148820&cm_re=crucial_ssd-_-20-148-820-_-Product) I am currently using up 245 GB of space on the HDD I'm using now. Would there be enough room to clone my HDD to the SSD?
Thanks

Generally, for cloning to a 250/256GB SSD, you need the used space to be under 200GB.
For instance, the Samsung migration software will throw up an error if there is more than that.

But for your case, you can probably easily find 50-60GB of stuff (media/music/etc) that can be moved elsewhere.
And in normal operation, you don't want to go over 200GB used space on that drive. You have to leave 10-15% free anyway.

That's OK, I can just uninstall a couple games to get under the 200 GB mark. Would 195 used GB on my HDD be too much to clone to an SSD? So for the 256 GB SSD, I am really getting less than 200 GB of usable space?

About 240GB (well, a little under), after formatting

195GB is right at the top end of actual, usable, space. You need to leave free space for the TRIM function to work.
So, you won't be able to install much else on it.

A drive advertised at "250GB" actually reports as 232GB. But you still need to be well below that for actual use.

here's a trick that almost nobody seems to know:

right-click on your C:\ drive, select Properties, and you'll see a pie shape. you'll see numbers for Used and Free space, and Capacity. so far so good. the trick is to NOT look at the number on the right (example 204GB), but to look at the number on the left (example 219,817,234,900 bytes). THAT number on the left tells you it's (basically) 220GB, the exact same Gigabytes that are used on the packages of SSD drives and HDD drives. your 3TB hard drive would have a capacity number of 3,003,234,674,324 bytes or something like that, along with a number like 2.72TB

technically, the number on the left with all the commas is the actual number in MB, GB, TB, and so on. actual true Gigabytes and Terabytes.
the number on the right is actually in MiB, GiB, TiB, and so on. but for assinine reasons the letter i is skipped over, because it's more fun to really confuse people saying "oh, some capacity is lost due to formatting" (which is utter *)

What does MiB, GiB and TiB mean?

read n learn! it's the "buggered up" Megabyte, forced into multiples of 1024 instead of 1000
