Plasmon UDO30I external SCSI Drive - Page 5

Conclusion

UDO uses its own phase change recording process, offering one of the most robust storage methods and ensuring data integrity at the most fundamental level. Target markets for UDO technology include banking, telecoms, insurance e.t.c where the need for high reliability in storage is high (our tests could not confirm whether this device is indeed highly reliable, since that would only show up with long term useage/testing).

The results reflect low overall performance with the drive. SCSI Mechanic 3 gave us sequential read transfer of about 6.45MB/s and 9.8MB/s write transfer. Analyze Disk measured average read access time of 61.7ms and average write access time of 87.65ms placing the drive in the low performance devices category.

When copying, to keep performance high, the manufacturerer recommends copying up to 1000 to 1200 files per directory at a time. Also, the user must be sure that there are no other UDF (DVD) file systems installed as they interfere with the UDO driver software.

Desktop UDO drives are priced at approximately $3,200 USD. The price is rather high for end users, but Plasmon is aiming at the Proffesional market, where reliability is important.
