too lazy to explain, but meh wants!

lol, great idea... except the defrag part... that's pretty dumb

Dude it went SO FAST

true... but more then speed needs to be considered when looking at SSDs

Solid State media has a lifetime determined by the number of writes to each sector of the drive before the drive cannot store data anymore. New SSDs actually write the entire span of the disk before repeating; to spread the wear evenly over the disk sections.

Defragmenting rearranges the blocks of data on a hard drive so that the file blocks are read in sequence, boosting seek time. Some defragment software arranges the more used programs on the faster edge of the platter as well so that those programs can be accessed quicker. All this is done to increase seek times for any given file and in turn boost read speed.

With solid state media, defragmenting causes unneeded writes to a disk making its life shorter, and would not increase efficency as SSD's have an almost instant seek time which is the very thing that defragmenting lowers.

But don't let that fool you, I am still impressed by the set up all in all, I love SSDs

yeah the speed is insane, one day....one day I tell you!

hm, too bad I don't have the link anymore, but I've read that fragmentation has even a higher effect on SSD drives, there was a benchmark showing that a 200mb/s (read speed) SSD went down to 80mb/s because of fragmentation. some drives of the latest generation even have an on-board defrag feature that runs when the HDD idles (Corsair extreme series if I remember it right)....

I shouldn't have watched that .... now I have to sell my soul and maybe an arm and get that >_>

*drools*

@cats you should think of a smiler project but maybe testing password speed cracking ability? see if u can get some free samples from the SSD companies lol

rainbow tables where already "fast" on SSD right?

how fast would bruteforcing go with this :/

Why on earth would this in any way affect brute-forcing?

6tb of memory? that should really help pushing the limit.

hmm... worth considering. I have an old SSD in storage, I'll run a defrager on it and post the findings.

on a 2 year old 120MB SSD running windows XP on an NTFS partition.

fragmentation was 8%

before and after defragmentation read speeds were 80mb/s

on the upshot, it shows how far read speeds have come in the SSD market lol
