The Ricoh Mp7125a with just link (Ricoh’s name for burn proof) this is a good reliable performer, a well-built unit supplied with Nero 5 writing software. After 6 months of daily use I have yet to have a buffer underun, for a price of just under £100 this machine is well worth considering. I actually paid about £30 more than this when I bought mine. As with other Ricoh CD-RW drives, maintains a maximum read speed of 32x for CD-R and CD-RW media, as well as for CD-ROM. Because CD-RW media has a lower reflectivity than CD-ROM or CD-R media, amplification circuits are more susceptible to noise. This fact causes difficulties with high-speed CD-RW reading, and currently most CD-ROM drives, even 40x drives, can only read CD-RW media at about 20x at best. However, Ricoh have succeeded in minimizing circuit noise in their drives by using a hologram optical system and low-noise preamp, making it possible for CD-RW media to be read at high-speed in the same way as CD-ROM media. Buffer underrun errors caused by data transfer lag have been a constant problem with CD-RW drives. The JustLink system, independently developed by Ricoh, automatically prevents buffer underrun errors by predicting them before they happen. JustLink, first introduced with the Ricoh MP7125A drive, provides writing stability in the following situations where buffer underrun errors could occur easily with a conventional drive. With high-speed writing. When some other operation is being performed on the computer during writing. When writing CD-RW drive from a CD-ROM drive. When writing the data on the network directly Conclusion: A very good drive for this kind of price.
