The problem early on, and i might be dumbing this down a bunch or completely wrong, but they used to have a problem after having been wrote too and erased a bunch.
The onboard 'chips' that controlled where the data was stored would work in a pattern like this:
(left to right, left is the start)
00000000000000000000000000000
00000000000000000000000000000
00000000000000000000000000000
00000000000000000000000000000
So say 0's are the current info stored on the drive well then you delete a video that you had or a game, you get:
00000000000000000000000xxxxxx
xxxxxxxxxxxx00000000000000000
00000000000000000000000000000
00000000000000000000000000000
So a week later you delete a bunch of old games you don't play:
00000000000000000000000xxxxx
xxxxxxxxxxx0000000000-----------
------------------------------------------
------------------------000000000000
Then Starcraft II comes out, and it decides to write some of it here, and some of it there:
0000000000000000000000xxxxxx
xxxxxxxxxxx000000000SSSSSSSS
SSSSSSSSSSSSSSSSSSSSSSSSSSSS
SSSSS----------------000000000000
And now you've reached that point where you want to install FFXIV (god why i don't fucking know, because it's horrible) so you install it and:
000000000000000000000xxxxxxx
xxxxxxxxxxFFFFFFFFFFSSSSSSSS
SSSSSSSSSSSSSSSSSSSSSSSSSSSS
SSSSSFFFFFFFFFF0000000000000
FFFFFFFFFFFFFFFFFFFFFFFFFFFF
etc...
So basically, it would get "fragmented" and after awhile it would take the drive longer to find the data it needed than if it were on a spining platter, because it would only read/write in one direction.
This was how I understood it, and from what i've seen recently, the controllers on some of the newer drives will actually "clean up" afterthemselves, when it comes to writing/deleting new data.
Those two that TGM suggested should be on point, OCZ usually dosen't put out inferior chips/storage devices (memory,usb,SSD's)
