Thread: Seagate Momentus ST9500325ASG

The Momentus series of 2.5-inch drives from Seagate are great notebook storage solutions. The ST9500325ASG model that we received has capacity of 500 GB with an 8-MB cache.

Seagate has used a two platter design for this 2.5-inch drive. This drive is 9.5 mm thick which is the standard for 101ebook hard drives now.

Synthetic benchmarks aside, this drive did well in our real world tests too. It took 56.4 seconds to write 34-GB sequential file and 72.7 seconds to write 4-GB assorted data resulting an Image write speed of about 5448 MBps (sequential and assorted). Read times ere also mighty impressive 4 GB of sequential data took 60.6 sec while 4 GB of assorted data took 67.7 sec giving an average read speed of also 64 MBps. Opening a 1 GB Photoshop image took 60.6 seconds, which is really great for a notebook drive. The only area where this drive lost out in performance was when we did an internal file copy of the 4 GB data files. This hard drive look about 240 seconds for both sequential and assorted files.
