TapeXpress T490e
Reliable, field-proven tape path design and components High appeal to library system integrators Percentage-of-tape-remaining display High-performance, 3 MB/second data transfer standard Fast/Wide SCSI option Flash PROM’s, easy firmware upgrades
One Drive Serves A Full Range Of Half-Inch Tape Drive Needs
Now full 18/36-track read and write performance is available in a single tape drive for lower performance and mid-range systems. Whether you use 3480/3490 18-track for interchange, or 3490E 36-track for high-performance backup, the compact versatile T490E is ideal for PCs or workstations in office environments.
Designed For High-Performance Data Transfer
The T490E drive offers a sustained data transfer rate of 3 MB/second, using the standard Fast SCSI-2 interface configuration. The drive’s outstanding performance characteristics, coupled with its exclusive 18-track write capabilities, enable the T490E to uniquely and powerfully serve the needs of tape library integrators.
Interchange Needs Are Also Met
The T490E drive allows 18-track users to capitalize on their existing interchange investment, while also enjoying the benefits of 36-track performance and capacity.
Connectivity With major Backup And HSM Packages
The T490E drive easily connects to numerous hardware platforms, and is supported by many popular backup and HSM software packages.
Built Upon Success
Built upon Overland’s very successful TapeXpress products, the T490E tape drive offers 3 MB/second performance (20 MB/second burst max.) in a proven product design. The T490E is ideally suited for both single cartridge interchange and for times when fast backup of critical files is imperative. Its compact design makes it equally useful in a desktop application or stored unobtrusively in a busy data center. Taking advantage of system connectivity already designed into the TapeXpress product line, the T490E drive easily connects to numerous hardware platforms, and is supported by many popular backup and HSM software packages.
