TDK-branded Matsushita Electric Industrial Co., Ltd. (Type II, Single Sided, with CPRM and caddy, marked “for VIDEO”) 2-3x DVD-RAM 4.7 burned with LG GSA-H62N CL01. MID: M01J3004, Made in Japan. Scanned with a Samsung SH-S203N SB02 at 3x.

‘Drag and Drop’ of files was used in Mac OS X 10.5.4 using the Finder (first use, no formatting required - seen as UDF 2.0 disc) to fill all 4368MB. I basically used it as a “floppy disc” and found appropriately sized files to fill it up to maximum capacity. Transfer of files lasted approximately 1:15min (est. 1MB/s). 90 DQ score all the way until 99%, as 99%-100% yielded a PIE spike of 1664 and a PIF spike of 208 which made the Disc Quality score 0. Included are graph-limited screenies of the Disc Quality tab (Max PIE=60 and Max PIF=5) as well as an Automatically adjusted graph to show the 1664/208 PIE/PIF spike at the end.

Expensive disc, but if it’ll last a lot longer than my DVD+/-RWs it’ll be worth it. The ease of use as an “optical floppy disc” is great for small files (important everyday documents and files), and since all my drives have DVD-RAM support it’ll come handy as a secondary/temporary backup solution for some data (even if it’s labeled as “for VIDEO” ). It still won’t beat the ease of use of USB Flash drives but I personally find it cool.
