Azz... solo 750 cicli P/E per la versione con memorioe TLC? :/
 
P.S: Eccellente lavoro, come sempre :)
 
 

 Azz... solo 750 cicli P/E per la versione con memorioe TLC? :/
 
non e' ancora confermato, ma si parla di 750 cicli su diversi siti
 
secondo me potrebbero anche essere di meno in quanto
il degrado e' tanto piu' alto quanto il carico di lavoro, un conto
e' usarle su dispositivi quali tablet, smartphone (ecc..) , un'altro
e' con ultrabook, notebook e desktop ..
 
non dimentichiamoci che anche il processo produttivo e'
diverso, non sappiamo molto dei 21nm Samsung (vale anche
per le MLC degli 840 Pro), ovviamente l'ottimo comportamento
dei 27nm lascia ben sperare, ma non e' una regola scritta
 
spero che facciano subito dei test pratici di longevita',
idem per altri prodotti con le Toshiba/SanDisk 19nm
o le prossime Intel/Micron 20nm
 
due curiosita', attualmente OCZ impiega delle memorie
20nm negli Agility 3 120GB (con p/n che termina con .20),
mentre ho notato che esiste il Vertex 4 512GB M , dove
la "M" indica l'utilizzo di memorie Micron ONFI sincrone 25nm
(costa meno del modello con memorie Intel)
 
grazie per l'incoraggiamento, Lorenz, nei mesi passati ho
comunque aggiornato l'archivio con i prezzi, ma non li ho
pubblicati .. se a qualcuno interessa (per statistica)
li posso pubblicare o caricare da qualche parte

non e' la prima recensione, ma e' esaustiva spiegando
in modo dettagliato le differenze tra SLC; MLC e TLC
 
a pag. 2 il riepilogo cicli P/E e tempo di lettura, programmazione
e cancellazione delle Flash NAND (valori approssimati)
 
SLC (1 bit per cella) 100000 P/E read/prog 25/200us erase 2ms
MLC (2 bit per cella) 3000 P/E read/prog 50/600us erase 3ms
TLC (3 bit per cella) 1000 P/E read/prog 75/900us erase 4ms
 
estratto da pag.3 :
 
"The difference between SLC, MLC, and TLC is pretty simple: SLC has the
fewest voltage states and hence it can tolerate bigger changes in voltages.
With TLC, there are eight different states and hence a lot less voltage room
to play with. While the exact voltages used are unknown, you basically have
to divide the same voltage into eight sections instead of four or two like
the graphs above show, which means the voltages don't have room to change as
much. The reason why a NAND block has to be retired is that erasing it
starts to take too long, which impacts performance (and eventually a NAND
block simply becomes nonfunctional, e.g. the voltage states for 010 and 011
begin to overlap)."
 
"There is also more and more ECC needed as the NAND wears out because the
possibility for errors is greater. With TLC, that's once again a bigger
problem because there are three bits to correct instead of one or two. While
today's ECC engines are fairly powerful, at some point it will be easier to
just retire the block than to keep correcting errors."
 
a pag. 4 si discute sulla longevita' , teoricamente con 10GB
di dati scritti al giorno ed un alto write amplification,
si passa da 10 anni (MLC) a 3,5 anni (TLC) per il modello da 128GB
e da 21 anni a 7 anni per il modello da 256GB
 
da stabilire quanto incidera' in pratica ..

Grazie per il link...in effetti chi si prende un modello da 128GB e lo 
dovesse usare intensamente, alla fine non gli durerebbe molto rispetto 
ad un SSD con memorie MLC.
