Seagate Barracuda LP 5900RPM Green SATA 3Gb/s 1TB Hard Drive ST31000520AS Review

Filed under: Hard Drives,Reviews |

Hard drives have been around for along time and they’re taken for granted I think. You can get them in varying sizes and speeds and all of them have their uses. Today for review I have the Seagate Barracuda LP 1TB hard drive which is a green drive that runs at 5900RPM and uses lower power than faster drives of similar size. I’m curious by nature so I put this green drive up against a regular 7200RPM drive for comparison, so let’s get to it…

The Review::

It’s a hard drive, it doesn’t look that much different than any other one. Not much to be said about it at all.



For comparison I put it up against the Seagate Barracuda 7200.12 1TB hard drive.



I ran some quick testing on both drives to see how they compared to each other. One is 7200RPM while the other is 5900RPM, I was certainly curious as to how they compared to one another.

The first test would be Atto:

sea4 seagate lp atto

Obviously the 7200.12 is faster as it’s a 7200RPM drive, but speed isn’t really the point with this type of drive is it?

The next test is Crystal DiskMark:

sea7 crystakmark seagate lp

101 Read and 99 MB/s Write isn’t bad for a 5900RPM drive I think.

I ran two more tests from SiSoft Sandra 2011 as well.

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

File Systems

If we look at this test we see the performance is actually close at the file system level.

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

Physical Disks

Here in this test we don’t see any surprises at all, the 7200.12 is faster as expected.


One thing I did notice while testing the Barracuda LP is that it can get rather hot to the touch under load, uncomfortably hot actually. What that means exactly I’m not too sure as it feels about the same as the 7200.12 does under load. Still I was expecting a ‘green’ drive to run cooler than a faster one would.




I’m not sure I would use the Barracuda LP as my main hard drive as it’s a bit slow really. It might not be bad for an HTPC system but still the heat bothers me a bit for that kind of usage.  Right now I’m using a green drive in my computer for my automatic backups and that’s where I think this drive would fit perfectly.

The drive does power down when not in use it seems and then power back up very quickly when needed.



+Green, low power drive
+Large capacity
+Can be SATA 6 gb/s
+Decent speeds
-Can get hot to the touch
