Ein externe Festplatte (Hard Disk) zum Speichen meiner Daten

For working with my tablet computers I need more storage space than the built-in storage of 32 GB or 64 GB. So I decided to use a mobile hard disk of 500 GB or 750 GB or 1 TB. Now I am looking for a suitable external enclose and the disk itself.

My requirements for the external disk enclosure

  • Form: usable for 2.5″ disks of 9.5 mm height
  • Size: Super Slim i.e. max. 13 mm high
  • Limitation of disk storage capacity: 1 TB or even better if no limitation at all
  • Controller: SATA-300
  • Data connection to computer: USB 2.0 or better (say: eSATA or USB 3.0)
  • Normal power supply: via USB data connection (5 V, 500 mA = 2.5 Watt)
  • Extra power supply by 5V DC-In

My shortlist

  • Raidsonic MB668U3-1SB
  • Raidsonic MB668US
  • Raidsonic MB668U
  • Raidsonic IB-250StU3
  • Raidsonic IB-266StUS-B
  • CnMemory Core 1,6 mm
  • igozz slim 1TB

My elaluation

Raidsonic MB668U3:
13mm, 5V DC-In, unlimited disk capacity, USB 3.0
Raidsonic MB668US-1SB:
Same as above, but USB 2.0 only and capacity limit 750 GB
Raidsonic MB668U:

Raidsonic IB 250StU3:

Raidsonic IB-266StUS-B:

CnMemory Core
Abmessung: 122,5 mm x 77,5 mm x 14 mm
