I got this drive about a month ago from 'dglet'. I tested the drive and it's free of bad sectors and offers a good sustained transfer rate of about 200MB/s maybe a tad more on the outer edge of the platters. It can copy a large file to itself at a rate of nearly 60MB/s (60MB/s write + 60MB/s read) when the drive is empty, therefore on the outer edge of the platters. When nearly full (only 100GB free) it's about half that speed, 30MB/s of copying a large file to itself. Very good for a mechanical drive. But random access performance isn't that good. HD tune pro measures the average access time to be 17.5ms! That is very high for a 7200RPM desktop drive. That is in fact worse than most 5400RPM greenpower desktop drives. For instance, the 5 platter 6TB Caviar Green 5400RPM drive has a better access time of about 16ms, so what's the point of 7200RPM besides better sequential transfer rates.. My 2TB Caviar Black 7200RPM drive is 12ms. The seeking noise isn't that quiet but isn't super loud either. Expected it to be quieter with a slower average access time. The real CON about this drive is the firmware, version CC48, aggressively parks the heads to save energy. Within about 20 seconds of being idle, it'll park. But then when the drive gets a read or write request, the drive has to do an initialization in order to come back online! Take a good 1.5 to 2 seconds each time so you get delays. This is very bad for a performance drive. The noise if annoying too. You can disable APM (Advanced Power Management) with CrystalDiskInfo or other utilities, so the heads will never park, and there are probably ways to automate this so you don't have to mess with the APM settings every time you plug the drive in (because the settings do not stick after a power cycle), by enabling 'auto AAM/APM adaptation' in that program so you just have to launch that program every time you plug the drive in, and it'll automatically disable APM, then you can close the program. But still a very big CON. The power savings is minimal to park the heads, maybe 10% lower idle power usage at most. Here is a video of this, with good audio;;; Google "Seagate ST6000DX000 6TB 7200RPM drive head parking issue" It runs hot. About 48C in a 25.5C room when idle, about 55C if busy for a long time. About the same if not a bit hotter than some other high capacity 7200RPM drives. But with an external enclosure that has a fan, it stays at 34C or so. 10-12 watts from the wall, not accounting for the inefficiency of the AC adapter of the external enclosure, the enclosure's fan being off. Not sure if this 7200RPM drive is worth it given the increased seek noise and heat versus a 6TB 5400RPM drive from Western Digital. Takes about 3 minutes for the drive to search itself for a file (nothing indexed) when nearly completely full, versus about 2.25 minutes for the 6TB Caviar green 5400RPM drive.Read full review
