Garbage Collection Algorithms Coming For SSDs
MojoKid writes "A common concern with the current crop of Solid State Drives is the performance penalty associated with block-rewriting. Flash memory is comprised
of cells that usually contain 4KB pages that are arranged in blocks of 512KB. When a cell is unused, data can be written to it relatively quickly. But if a cell already contains some data, even if it fills only a single page in the block, the entire block must be re-written. This means that whatever data is already present in the block must be read, then it must be combined or replaced, and the entire block is then re-written. This process takes much longer than simply writing data straight to an empty block. This isn't a concern on fresh, new SSDs, but over time, as files are written, moved, deleted, or replaced, many blocks are a left holding what is essentially orphaned or garbage data, and their long-term performance degrades because of it. To mitigate this problem, virtually all SSD manufacturers have incorporated, or soon will incorporate, garbage collection schemes into their SSD firmware which actively seek out and remove the garbage data. OCZ, in combination with Indilinx, is poised to release new firmware for their entire line-up of Vertex Series SSDs that performs active garbage collection while the drives are idle, in order to restore performance to like-new condition, even on a severely 'dirtied' drive."

See my subject-line above, & the url I just posted, where I await your reply... that ought to be good for another large laugh, lol!
"Surely you're suggesting this in jest? - by ion.simon.c (1183967) on Saturday August 08, @12:27AM (#28993767)
No, but YOU must have, what with this statement from you there:
"2) You're talking to APK. He exists to write wall-of-text comments. His depth of knowledge is *really* shallow, so don't expect a good conversation out of him." - by ion.simon.c (1183967) on Thursday August 06, @08:09PM (#28980845)
In regards to that statement from you I just quoted... well, again: See my subject-line above, & the url I put into this reply... see you there, coward.
LOL, ever see the film "The Watchmen"? IF NOT?? Then, do see it...
I simply state that, because... Well - Since you make me laugh, often quite hugely, in your trolling of myself here?? ALL I can think of, is @ the start of that film, when "the Comedian" (you, in this case, since you make me laugh so much), gets his behind handed to him, by Ozymandias...
Because the list I produce there in that url above? Clearly shows I have such works + that I have done fairly well in this science of computing, whereas by way of comparison?? You have nothing like that list to YOUR credit...
(SO - Despite your stating I have a "shallow level of know-how" in this art & science... WELL - just based on the partial list of things I have been fortunate enough to have been graced with, by OTHERS?? Opinions, clearly vary, and, outnumber yours (as well as being from RESPECTED publications, books/magazines/newspapers/forums articles & more, that are FAR MORE CREDIBLE than yourself))
BOTTOM-LINE: Most of all? It's no "crime" to have done well, & to be able to put it out, vs. attackers like yourself, trolls, that have never done anything they can evidence to that effect, that helps others - I do so, to merely defend myself vs. your false allegations directed MY way (& that one above is NOT a "1st" from you either...).
(One would think that someone who has done well, & can evidence that easily, has a deeper level of knowledge in a science than one who clearly, does not... such as yourself. You never seem to learn, so, it's time for "another lesson" to be taught to you, & as usual, you ONLY BRING THIS ON YOURSELF, in attacking myself!)
APK
P.S.=> You came into the url I posted above, implying things about me that are negative & untrue (per your own words quoted above NO LESS)... now, it's "time to face the music" there, & "eat your words", ONCE AGAIN (what is this now? The 2nd or 3rd time you have tried this on me, always to your own dismay no less?)
Have some "intestinal fortitude", & back up your b.s. there then - so, once more, per my subject-line above?
Why are you running from that reply of mine to you, complete with the quote of your own lame accusations/implications you stated in regards to myself?? Perhaps because my reply will show you for what you are???
I think, no rather KNOW, so... &, so will anyone else reading there! apk

Ahem: "Beg to Differ" - There is nothing "crazy" about facts that disprove b.s. in trolling attacks on myself (Especially facts that easily & clearly disprove the quote of Ion.SIMIAN.c's own frothing b.s. that came spewing out of his pie-hole - which strangely resemble your reply here (thus, you are nothing more than another of his multiple "sock puppet" accounts ion.SIMIAN.c uses to bother others in his trolling others on this website)).
By the by: GOOD CHOICE OF A NAME FOR THIS "SOCK PUPPET" ACCOUNT OF YOURS, ion.SIMIAN.c - as you always bring your own destruction upon yourself, so it makes sense!
And, no - it's NOT "ok" for ion.SIMIAN.c to attack & troll others, without some "remuneration"... so, let him, defend himself (not via sock puppet either, as we all know YOUR tactics on this account, ion.SIMIAN.c ...)

Anyone is free to read my last reply, inclusive of ion.SIMIAN.c's trolling attack on myself, & my rebuttal reply which is loaded with easily verified concrete visible facts, which clearly disprove his trolling b.s., easily... "TOO easy" - & I will allow others (no, not "sock puppets", like you) to judge for themselves.
(Plus, I think it is BEST that ion.SIMIAN.c defend himself... instead of "you", sock-puppet, and, in the very thread in question where he attacked me!)

Thank you, too bad I cannot say the same to you "Random Destruction" (another one of Ion.SIMIAN.c's multiple 'sock puppet' accounts he uses to troll others, clearly)... apk
