Retail Price:RM1,888.00

The Shape of Serious Storage
Fujitsu's DynaMO 640SE external magneto-optical drive delivers on today's requirements for dependable data storage. Peak performance, high capacity and disk reliability give you everything you need to run applications, back-up entire systems, and archive large files. The DynaMO 640SE's fast SCSI-2 interface supports data transfer rates up to 3.9 MB per second, equivalent to a 26X CD-ROM! Using an Over Write (OW) MO disk can improve write performance by 50% over standard MO disks. MO disks are ideal for graphic, CAD/CAM, desktop publishing and other demanding applications that generate large files. Very low latency and seek times enable the DynaMO 640SE to be almost as responsive as a hard disk drive, yet offer the flexibility of removable media, giving you unlimited storage capacity.

Rely on Fujitsu MO disks
Your valuable data represents a sizeable investment. If you're serious about keeping your investment safe there's no practical substitute for the superior reliability of MO disks. They're rugged enough to withstand hostile environmental conditions, such as moisture, dust, shock, vibration, magnetic fields and X-rays. MO disks protect your data better than ordinary magnetic media. Whether you're transporting, backing-up or archiving, you can depend on DynaMO and MO media.

Wide Range of Disk Capacities
The DynaMO 640SE can read and write to every capacity of ISO compatible media including, 540MB, 230MB and 128MB. Backward compatibility means that your investment in previous capacities is protected as well. No other removable storage solution offers as many options. Whatever shape your storage needs come in DynaMO offers the flexibility and security to meet them.
