Memorex True 8Xn external DVD±R/RW Recorder - Page 1

NeroInfoTool gives us a quick look at the drive's specs. The drive uses a 2MB buffer memory and supports buffer underrun technology for both CD/DVD formats, RAW DAO 96 writing (CD) with firmware v1.G1 that was used for all our tests. Mount Rainier isn't supported.

DVDInfoPro gives us some additional details about the drive's abilities as well:

- The package

The retail box includes the external drive, one USB 2.0 cable, one firewire IEEE-1394a cable, the external power supply unit and one CD with Nero Express Software Suite offering: Nero Express 6, NeroVision Express 2, InCD, Nero BackItUp, Nero ShowTime, Nero Cover Designer, Nero Recode 2, Nero Media Player, PhotoShow Deluxe. Also included are a quick installation guide and software manual.



The external case has a unique look (see photo above), and plays with silver & black colors. On the front panel, there are the brand name next to the 8X logo, CD-RW, DVD-R/RW and DVD+RW logos, all on the loading tray, under which we have the activity led, emergency eject hole, phone jack, volume level control and the eject button.

The rear side has the analogue audio output connectors (Left-Right), two firewire IEEE 1394, one USB 2.0, the DC in and the power on/off switch.

On the drive's label located topside, is available the manufacturing date (February 2004) and the manufacturing line (Made in Malaysia). We can see that the drive is the NEC model ND-2500A.

After removing the bottom plate, we can see the basic layout of the drive's PCB. The main chipset is from NEC, and the entire board is the same as the board found in the NEC 2500A drive.
