CDRInfo heeft zojuist een review gepost van de nieuwe Yamaha CRW2100E, een IDE cd-rewriter met een erg relaxte snelheid van 16/10/40. De 16x write en 10x rewrite snelheden zijn wel wat misleidend omdat er geschreven wordt dmv de CAV methode. Dit heeft als gevolg dat er niet met constante snelheid gefikt wordt, maar de snelheid na verloop van tijd pas maximaal is. Uit de testen bleek dat dit bij CD-R's niet zo'n grote impact had; de gemiddelde brandsnelheid was daar 15,67 speed. Helaas waren de CD-RW (10x CAV) erg teleurstellend te noemen, vergelijkbare 10x herschrijvers waren tot wel 30% sneller. Een bijkomend nadeel van de CRW2100E is het ontbreken van een anti-bufferunderrun techniek waardoor de 8MB buffer het enige vangnet is. In meeste gevallen bleek dit echter voldoende, mits de gebruiker niet al te heftig gaat multitasken tijdens het brandproces. Hieronder heb je wat stukken uit de test:
Verdict of CDR Results:
The Yamaha CRW2100E performed very well in most of our CDR Tests. The drive supports 16x-writing speed, which even thought is not full 16x (15.67x average), works very good. The 8mb buffer and the proper software will generally protect you from buffer underruns. Don't expect miracles. With normal use (Internet Surfing, Word, Excel) the drive will wring at 16x without any problems. Problems will appear when you start opening many applications. If they also use the HD very much you will probably get a coaster. The drive doesn't seem to support DAO-RAW even Yamaha insists on the opposite. Last the drive supports overburning and goes only up to 89mins as most the other drives do.Verdict of CDR-W Results:
The Yamaha CRW2100E is not the best choice for RW writing. Even though the drive supports the new HS RW writing mode, it misses to support the higher (10x) writing speed of it. The competition supports 10x writing and CRW2100E cannot have any chance against it. Even in the packet-writing test, which Yamaha supposed to support 10x, the speed is not competitive. It is actually 4x and increases to 10x at the end of the disc. That is probably why the results (4.96x writing) were very bad. The competition is nearly 30% faster.The Yamaha CRW2100E is a very interesting drive from many aspects. It is the first drive that supports 16x writing speed and 40x reading speed. Those two features are the best weapons against the hard competition from other manufacturers. However there are some features, which don't help the drive to claim the title of the best recorder around. The lack of 10x writing speed and of any anti-coaster technology is what really you will miss from the drive. There is also a issue with DAO-RAW writing mode but we will leave it out since by the time we write those lines it is unclear if the drive supports or not it... We feel that the SCSI model (CRW2100S) probably would fit better to our needs and will work better with low end powered computers.
