BIOSTAR G330 SSD Review (256GB)


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.

Initial results with ATTO are all positive. It’s performance ramps up quickly as the file sizes change. it is at peak performance at 256KB where it achieved 563MB/s read and 517MB/s write.


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

The BIOSTAR G330 doesn’t let us down again. In Crystal Disk Mark, it achieves nearly the same as it is rated for by the company, 563MB/s read and 515MB/s write. We also get to see that it delivers good 4K performance with QD1 read and write coming in at 37MB/s and 146MB/s respectively.


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst-case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

In AS SSD the BIOSTAR G330 achieved an overall score of 1036 points. The sequential performance came in at nearly 530MB/s for read and 490MB/s for write. 4K QD1 performance is similar to CDM, although slightly lower as is usually the case. Here AS SSD shows us high QD IOPS performance as well. It achieved 64K-87K IOPS read/write. In the Copy benchmark, it also showed very good performance with 503MB/s being the highest during the ISO portion.


Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

Anvil Storage Utilities, just as the other benchmarks before it, confirms all the results we have seen. It achieved an overall score of 4,583 points as well.

    Mr. Webster, thank you for the review. Based on the data here I think this G330 will be a severely tough sell for Biostar in the current SSD market.

    The performance is unfortunately dreadful (you pointed out the “almost 6 minutes to transfer 30GB of movies”) it forced me to double check this wasn’t a HDD review. Just checking the pricing for Samsung’s 850 EVO (the 250GB model) shows $90 on Amazon. I cannot possibly imagine anyone buying G330 over 850 EVO.
