Titolo: Spesa al bancone dei cd

Ciao a tutti !
Stasera sono andato a fare la spesa di cd in un nuovo negozio che era
un po' piu' fornito degli altri a cui sono abituato.
Questo e' il risultato, aspetto vostri commenti:

il negozio è molto caro, addirittura ha i traxdata da 90 a 1,2 euro...a 
RO si trovano a 0,65 fai un po' tu. 
Saluti

si, anche Tomalak, il 30 % di questo ng è di Rovigo! 

RO si trovano a 0,65 fai un po' tu. 
Sai qual e' il dramma? che e' uno dei piu' economici! si trovano cd a
meno, ma sono tutti di o bulk o comunque di qualita' scarsissima....
Tra quelli che ho elencato quale mi conviene prendere?

Ma va?
Magari ci conosciamo pure...
Ciao,

RO si trovano a 0,65 fai un po' tu. 
Ieri sera al Mediaworld di Milano-Rubattino erano a 0,69 (ribassati da
1,19 iniziali, se non sbaglio)
SNAFU

 Questo e' il risultato, aspetto vostri commenti:
Boh...
Io all'Auchan ho preso i Verbatim DataLife 40x 700MB...
0.49 Euro l'uno...
Non sono i DataLifePlus... ma non mi hanno MAI dato problemi, ad essere
sincero...
Ciaooo

i superazo

 sincero...
Sembrano proprio i cd che sono stati giudicati scarsi da test condotti 
dalla rivista tedesca PCWelt:
----------------------------------------------------------
High 32-40x speed media delivers unacceptable quality!
Created: 13/Jun/2002
Last updated: 30/Jun/2002
A German website PC-Welt.de has done extensive testing with latest high 
speed 32-40x certified media. The conclusion is that current high speed 
media delivers unacceptable error rates. The tests have been done with 
latest Lite-On and Plextor drives. 
The content and test results of this article are copyright PCWelt.de. 
Translation and summarizing was kindly provided by CiTay
Verbatim CD-R 700 MB 32x:
Error rates skyrocket after the first half of the disc at 32x. Lowering 
the speed to 20x or 16x doesn't help much. Especially prone to this are 
the Plextor and Benq 40x drives. Lite-On 40x works a bit better with 
this disc. Average BLER is 26.43 errors/second. High. Good CD-Rs like the 
Teac 24 have 0.77 errors/sec here. Maximum was a surprising 196 
errors/sec: immensely high! The hardware CD-R tester asserted both E22 
and E32 (uncorrectable) errors - very bad! Atip (Absolute Time in 
Pregroove): 97m 34s 22f 
Verbatim CD-R 700 MB 40x:
These Mitsubishi Chemicals CD-Rs are supposed to be for high recording 
speeds. Then Benq-burner, however, accepts only 32x speed, and with high 
error rates. Plextor and Lite-On 40x burners managed to burn with 40x, 
but with exorbitant error rates (the Lite-On was a bit better). Average 
BLER is 59.91 errors/sec, this is too high for reliable data archiving. 
Maximum BLER is 433.17 errors/second: Way, way above spec... it's not 
funny anymore! The hardware analyzer detected E22-Errors, at least there 
were no E32-errors. Still, quality rating can only be 'very poor'. Atip 
(Absolute Time in Pregroove): 97m 34s 23f 
Philips CD-R 80 40x:
It seems that Philips doesn't test their media. In the Benq 40x burner, 
the error rates were always above spec, same with the Plextor 40x. Data 
loss is likely. The Lite-On managed to do analyzable runs at 40x and 32x. 
BLER is 143 errors/sec average, 363.67 errors/sec maximum: A more than 
poor performance! To make things worse, the analyzer drive detected E22 
and E32-errors. This CD-R is basically garbage. Atip (Absolute Time in 
Pregroove): 97m 15s 17f 
Fujifilm CD-R 1-40x:
A CD-R with varying results. The 40x-max Benq burner decided to use 16x 
speed maximum, but with acceptable error rates. The Lite-On 40x burner 
wanted to use 32x, and this was a good decision, error rates are 
bearable. Only the Plextor goes all out and uses full 40x-speed for this 
CD-R: Bad move. Although the average BLER of 9.92 errors/sec is still 
okay, the maximum BLER of 103.17 errors/sec is out of question! 
Furthermore, there were E22 and E32-errors with the Plextor at 40x. 
Conclusion: This CD-R is unusable at 40x, the speed with the Plextor 
should be lowered manually by any means. Atip (Absolute Time in 
Pregroove): 97m 26s 45f 
Imation CD-R 32x 700 MB
Instable: This CMC Magnetics CD-R doesn't deliver. With the Plextor, Benq 
and Lite-On 40x-max burners, error rates are more than critical at 32x 
speed. The Lite-On burner managed to achieve half-decent results at 24x 
speed. The analyzer measured an average block error rate (BLER) of 30.02 
errors per second, quite much. But the maximum BLER of 171.17 errors/sec 
is dangerous for data integrity. Furthermore, there were E22 and E32 
errors. Conclusion: Don't use this CD-R for important data. Atip 
(Absolute Time in Pregroove): 97m 26s 66f 
Teac CD-R 700 MB 24x
Results of a good CD-R, to enable a comparison: 
This CD-R has an average BLER of only 0.77 errors/second and a maximum 
BLER of 14.83 errors/second. No E22 or E32 errors could be detected by 
our analyzer drive. Recommendable. ATIP (Absolute Time in Pregroove): 97m 
27s 56
