So, after a few days off I’ve got that last hard drive review for you, at least for a while anyway. The drive is the Seagate Momentus 750gb, model ST9750420AS notebook drive.
Info:
Product Name: Momentus 750GB Notebook Hard Drive
Author: Kristofer Brozio
Provider: Seagate
Price: $94.99 (from Amazon at time of review)
The Seagate Momentus drive delivers the highest available capacity and performance in a laptop hard drive and draw only .05 percent more power than a 5400-RPM laptop drive
The Momentus family of 2.5-inch laptop drives offers innovative options and features, such as capacity up to 750GB, two different performance speeds, and three significant features.
Key Features and Benefits:
-Seagate SmartAlign technology provides a transition to 4K sectors without the need for software utilities.
-Seagate Self-Encrypting Drives deliver government-grade encryption without performance degradation—protecting your data where it lives. The FIPS 140-2 options are NIST government-certified for both U.S. and Canadian usage with sensitive data.
-Seagate G-Force Protection technology can detect when your laptop is in a free-fall, swing the drive heads to a safe zone and keep the data safe.

The Review::
So it’s another hard drive for a laptop of notebook.
Ok, so let’s get into the testing:
Barracuda 7200.12: 133 MB/s Write and 134 MB/s Read
Momentus 750GB: 119 MB/s Write and 121 MB/s Read
Barracuda LP: 102 MB/s Write and 101 MB/s Read
Momentus 7200.4: 92 MB/s Write and 104 MB/s Read
Samsung HM500JI: 78 MB/s Write and 79 MB/s Read
Western Digital: 55 MB/s Write and 55 MB/s Read
I wasn’t expecting this little drive to be as fast as it is.
Next up would be Crystal DiskMark:
This is ordered by read rates, the Momentus performs just as well in this test. Not bad at all.
File Systems
Benchmark mounted file systems (i.e. volumes).
This is not the raw disk performance that other benchmarks test – but the speed of the volume itself that depends on many more factors like file system, operating system cache, position on disk, etc. Thus this is the performance you get at the file system level.
Drive Score: is a composite figure representing an overall performance rating based on the average of the read, write, and seek tests, and file and cache size. It is intended to represent drive performance under typical use in a PC
No surprises here at all, the Momentus still has a good showing.
Physical Disks
Benchmark hard disks (i.e. the disk itself, not the file system).
As the test measures raw performance it is independent on the file system the disk uses and any volumes mounted off the disk.
Drive Score: is a composite figure representing an overall performance rating based on the highest read or write speed across the whole disk. Thus the higher the better.
Access Time: is the average time to read a random sector on the disk, analogous to latency response time. Thus the lower the better
The score of the Momentus looks good I think with the Random Access time being the lowest of all.
Conclusion:
It seems this little hard drive easily compares to the larger 3.5” drives, the performance is just excellent overall.
The drive stays cool under load, which is what you want for a notebook drive of course.
PROS | CONS |
+Excellent performance +Stays cool under load +Fast random access time |
-None really |
