All 3 hard drives are very quiet and do not hear out of the system. The access sounds you can hear little that is really quite neat. All drives also run much vibration when you hold your hand on it you have to be very focused to realize that it runs at all.
The temperature is also very low at about 29 ° C in idle (all front chassis fan positioned) at 24 ° C room temperature. Under load the temperature then rises max. to about 32 ° C to.
I have all the plates hunted times by HDTune, Win7 x64. All plates I have the latest firmware from Seagate (currently CC46) updated, which incidentally went smoothly from equip.
System board (on all partitions running Windows 7 x64, quite full of data):
Access Time: 14.1 ms
Average transfer rate: 99.8 Mb / s
Min. Transfer rate: 49.5 Mb / s
. Max Transfer Rate: 128.5 Mb / s
Burst rate: 114.7 Mb / s
Data plate 1 (50% free):
Access Time: 13.8 ms
Average transfer rate: 102.5 Mb / s
Min. Transfer rate: 66.6 Mb / s
. Max Transfer Rate: 127.2 Mb / s
Burst rate: 176.3 Mb / s
Data plate 2 (about 20% free):
Access Time: 13.7 ms
Average transfer rate: 95.8 Mb / s
Min. Transfer rate: 62.1 Mb / s
. Max Transfer Rate: 124.2 Mb / s
Burst rate: 132.6 Mb / s
It is thus evident that the panels are working as fast even when full well.
The Samsung F3 1TB disks in the way were in the access time of 17.6 ms! and 15.7 ms (significantly) more slowly in the filled state. The transfer rates were at F3 although higher by about 5% than that of Seagate, but had violent burglaries, even with non-system disks. Also both clacked in burst and average test every now and then.
I have these plates then sent back, the sound is not really healthy for me. Especially since, according to various forums report also appears to be a bunch of problems with the Samsung F1.
So strong buy recommendation! I for about 14 years set by the way only to Seagate and lost among the now 15 hard drives I've installed even with friends and so no one. I hope it stays that way...
