This drive complies with SATA Revision 3.3. So SATA Power Pin 3 is for PWDIS (Power Disable Mode for SAS) If you have an older Revision 3.1 or before Power Supply; You will need to Remove/ Mask off Pin 3 on the power supply connector you intend to power this on with. Or use a 4 pin male LP4 molex to sata power adapter. If you do not it will stay in Power Disable Mode and not spin up/ power on!Note: Pin 1 starts at the notched part of the power connector plug; ¬Which will be the right most pin when insertedOn initialisation I obviously set GUID Partition Table (GPT) and Formatted as NTFS.I have already transferred 4.5TB of data from a Seagate Archive 8TB so the Hitachi is approx.using 50% of its 9.09TB usable capacity; remember a kilobyte (1000) is not equal to a kibibyte (1024 bytes) so if using windows for example the former is the metric it uses.Windows Reported NTFS Formatted Capacity: 9.09 TB (10,000,695,029,760 bytes)1 Terabyte is equal to 1.000.000.000.000 (10^12 bytes)1 Tebibyte is equal to 1,099,511,627,776 bytes (2^40 bytes) so 10 Tebibytes is 10,995,116,277,760 bytesIf your confused reading such large numbers to use the above 1 Tebibyte as an example in short scale prefixsThe 1, is how many TiB {1 Trillion bytes}the 099, is how many GiB {99 billion bytes}the 511, is how many MiB {511 million bytes}the 627 is how many KiB {627 thousand bytes}the 776 is how many bytes {776 bytes}Suffice to say this drive has a lot of spare sectors left over for remapping in the case of IO errors due to sector failure.I have included a screenshot of a few CrystalDiskMark x64 Benches I ranStorage Controller was Integrated Intel X79 Chipset SATA 6Gb/s port on Asus Sabertooth X79 MainboardDrive is 4643/9314GB used (50%)From left to right as you will see in the screenshots:First test was 1 Iteration @ 50 MB file sizeSecond test was 1 Iteration @ 100MB file sizeThird test was 3 iterations @ 100MB file sizeFourth test was 1 Iteration @ 500MB file sizeFifth test was 1 Iteration @ 2000MB file sizeThe first day I copied data on to it caching and indexing was a little annoying as throughout the first few hours of idle operation (from my perspective of not intentionally accessing it) after the large data transfer I could hear the drive operating (scratching away) every few seconds, it was pretty quiet here so it was very noticeable however I cannot comment on the individual idle acoustics of the drive as it is in there with a lot of other drives but upon accessing it is very noticeable. In comparison to a Seagate Archive 8TB 5,900RPM anyway which in my system is near silent on accessing. The closest I would compare this to in accessing noise level would be the old Maxtor's if anyone remembers them. I have mainly used modern Samsungs/ Seagates in my systems which for me have been very quietFurther on the noise topic I can comfortably say this drive does not resonate as some others have in the past for example some Maxtor's when new, I used the Maxtor as an example as I said before upon accessing they did make about the same sound/ basically it sounds like an old drive (circa 120GB/ 500GB) The sound of the running isn't the same as the older drives however, As idle acoustics from my chassis (CoolerMaster Dominator CM 690 II Advanced) are pretty much the same as before I installed the drive, so I cannot differentiate it between the 6 other mechanical drives out of a total of 8 (2x are SSD's)Additional info: (at time of submitting this)Ultrastar 10TB power on time = 2 days 21 hoursSeagate Archive 8TB power on time = 283 days, 11 hours
