Portable storage without the bulk
Thanks to the wonders of modern technology, Seagate was able to expand its ultra-portable "Seven" line of hard drives to 750GB (STDZ750100), which offers 50 percent more unformatted storage capacity than its existing 500GB (STDZ500400) model.
The additional storage space doesn't come at the expense of size or weight -- like its 500GB sibling, the 750GB measures a scant 7mm thick and weighs just 178 grams (less than 0.4 pounds). Seagate was able to accomplish a super thin profile by sandwiching a 5mm hard drive inside a 100 percent stainless steel enclosure consisting of two slabs of metal for the top and bottom. These are held in place by side braces.
This also gives the Seven series a premium look, which Seagate supplements with an included braided USB 3.0 cable 45.72cm (18 inches) in length. Speaking of which, the drive is bus powered, meaning it draws power directly from the USB port -- no external power supply is required.
We haven't tested either Seven drive ourselves, though according to Softpedia, the 500GB model posts reads and writes of around 101.2MB/s and 102.3Mb/s, respectively, which is about half the performance it saw from Seagate's Backup Plus Fast drive.
That's not very fast, though if you're looking for lots of storage in a portable and attractive form factor, the 500GB and 750GB Seven drives are viable options.
The new 750GB model streets for around $130, which is about 36 percent more than the street price of the 500GB model ($97).
