If I were to describe the 52x TrueX in one word, it would be "faster." The 52x TrueX seems to do everything that the 40x TrueX drive did, only faster. In appearance, the two drives are identical, save for the "Powered by ZEN" graphic being printed on the front panel, versus a decal. Once again, careful system planning is a must if you want to get the most performance out of the EIDE drive.
The same overclocked Celeron system was used for the 52x TrueX testing. Real-world file copies were even faster than the 40x TrueX, with the 553,008 KB Brood War file copying over in a minute and 17 seconds. This comes out to 7 MB/sec, or the equivalent of a 48x speed. I also performed the same test with a CD-R copy of the same disc which matched the time within a second or two.
