1 External hard drive (capacity: 4 TB (about 3.64 TiB), size: 8.9 cm (3.5 inch), connection external: USB3.0)
1 USB 3.0 cable (length: about 97 cm, connector types: A and B)
1 External power adapter (Input: 100-240 V 0.6 A, Output: 12V 1.5A Cable length: ca. 117 cm, barrel connector: about 5 mm / 1.5 mm)
1 Operating / installation / warranty Instructions (in DE, GB, IT, FR, ES, PT, PL, RU, B7 5 pages each)
While the AC adapter is not great, but at a possibly existing multiple socket outlet with 45 ° rotated slots it should probably for another device in the neighboring slot are scarce.
A rocker switch on / off is available at the back, but built unusually, namely downward rocked for "A" and rocked up to "Off". A lamp (blue for ON, even when hard drive standstill) is on the rear top of the chassis.
After connecting to the computer (Win7 64bit) and switching on, the hard drive is immediately detected and the correct driver automatically installs. The hard drive is preformatted in FAT32. I have reformatted to NTFS (partition style: GPT) with
4096 bytes per sector
4096 bytes per physical sector
4096 bytes per cluster
4096 bytes per file record segment
___1 Cluster per file record segment
The Windows 7's "Backup and Restore" is apparently optimized for 512 byte sectors and comes with 4096 byte sectors not clear (Disconnection: The backup destination was not found). However, with other freeware or purchase programs work backing up the data.
Since the Intenso warranty would expire by opening the case, I could read some 6.1.14 Disk characteristics and SMART values only via the software CrystalDiskInfo. Built is a WDC WD40EZRX-00SPEB0, GB 4000.7, 5400 rev / min, firmware 80.00A80. According to website of Western Digital Technologies, Inc. This is the product "4 TB WD Caviar Green SATA Hard Drive" (with no guarantee of Western Digital, for Intenso). The SMART values are all fine.
After a little more than 10 minutes of inactivity (no read and write access) is the hard drive stand, but is still present in Windows Explorer. A data access to the hard disk drives you automatically within about 10 seconds (except the data can still be retrieved from the disk cache). With a third-party software (eg. As NoSleepHD for Windows) of HDD arrest might be prevented.
If the USB cable from the computer, then the hard disk remains unchanged, it is reconnected to the computer, then the hard drive will restart.
If the hard disk is turned on and placed the supplied attached USB 3.0 cable too close to a MS 2.4GHz transceiver, then apparently disturbed the radio signal (jerky mouse movements). A relocation of the USB 3.0 cable further away from the transceiver, ended the radio interference or jerky mouse movements.
According CrystalDiskMark 3.0.3 x64 is Seq. Read at 157.8 MB / s and Seq. Write at 88.35 MB / s, connected to a USB 3.0 port. When connected to a USB 2.0 port is Seq. Read at 34.18 MB / s and Seq. Write at 29.20 MB / s.
According to HD Tach 3.04.0 varies in the range of 0 to about 2.5 TB, the sequential read speed between 120 and 140 MB / s. In the area from 2.5 to 4 TB, the sequential read speed increases from 120 to 80 MB / s continuously.
During several hours of copying the hard disk was barely audible. According CrystalDiskInfo reached while a temperature of 48 ° C. Placed horizontally or vertically, this had no different effects.
The surface of the plastic casing is glossy (piano lacquer), the look is sleek. The device is working properly.
