Seagate 600 SSD Review (480GB) – Seagate Enters The SSD Arena in a Big Way!


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Specifications for the Seagate 600 SSD list performance of 500MB/s read and 400MB/s write, whereas our ATTO results bump that to 554MB/s read and 480MB/s write transfer speeds.  Looking at the result, we can also see that performance jumps at the 4k size, as we would like to see it, and transfer speeds are solid throughout.


Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. In the Seagate 600 SSD, performance results are very similar whether we test with compressible or incompressible data and, for this reason, results are displayed utilizing incompressible data.

Crystal Disk Mark results remain strong, although they are a bit lower than our ATTO benchmark as is the norm.  IN examining the only comparative we have that uses the Link A Media controller, our result here is much better than that originally seen in our Corsair Neutron review.


Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data. AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

    Les can you get some sustained IOPS graphs over certain time periods? 🙂 The Corsair Neutrons were always good at this

    Nice review Les! I like it when you mention results from similar drives like neutron!
    Solid effort for first entry. Otherwise lame.

    That is a Corsair Neutron Clone for sure.
