REAL WORLD FILE TRANSFER
We also wanted to see how performance was in a real-world use when transferring large files to the SSD. For this test, we are going to simply stress write performance by transferring over a 30GB folder of movies off of a 512GB Samsung 950 Pro to the test SSDs and time how long it takes. Once complete we can calculate the average speed.
With an average transfer speed of 88MB/s, we can see that the BIOSTAR G330 trails behind all, except for a 2.5″ WD Blue HDD.
HD Tune is a Hard Disk Utility with many functions from error checking, health testing (S.M.A.R.T.), and of course benchmarking. To build upon our real world write test we also looked to see where the write speeds leveled off to by using HD Tune Pro. If SLC caching is being utilized, this test will typically show it.
Again, just as we saw with the real-world transfer test, the BIOSTAR G330 dropped down to an average speed of about 70MB’s after the initial SLC cache is full.
REPORT ANALYSIS AND FINAL THOUGHTS
Testing and taking our first look at BIOSTAR’s G330 was an interesting journey. Things started off well with our synthetic tests. In ATTO, AS SSD, CDM and Anvil, it got some great scores. Speeds were on par with the rated specs of 565MB/s read and 515MB/s write. PCMark 8’s normal routine even gave it a great score of 278MB/s. Things were looking great at this point. Not only was it reaching the performance numbers it was supposed to, it was doing very well during PCMark 8’s trace based testing. However, our next set of tests pushed the BIOSTAR G330 hard, maybe too hard. But, this is how we weed out the weak.
During after PCMark 8’s normal run, we put the hammer down and put it through its paces during the extended consistency test. During PCMark 8’s consistency test the G330 just completely fell on its face. It trailed behind the pack during the heavy workload portion of the test and never recovered to perform well in the recovery phase. It averaged around 70MB/s when most other SSDs averaged 175MB/s-225MB/s. Next, we secure erased the drive to ensure it was back into a clean state before we threw our real-world file transfer at it. The result from our transfer was, again, very underwhelming with an average of just 88MB/s. This put it behind every other SSD we have tested in recent times. Finally, we utilized HDTune to see its base write performance, which as expected, was very low at around 70-75MB/s.
Contrary to what the marketing seems to have stated, this BIOSTAR G330 SSD is not quite the premium SSD it is stated to be. It is not “Ultra-fast,” if it was, then it wouldn’t have fallen on its face during PCMark 8’s extended testing and it wouldn’t have taken almost 6 minutes to transfer 30GB of movies to it. It would be fast during write transfers, just as well as during read transfers. This also proves that it does not “offer 2 times faster data transfer rate than that of traditional SSD,” in contrast to their website’s claims. I remember back when I had a 128GB Plextor M5 Pro and it was able to sustain over 400MB/s writes till full, nearly 5-years ago… In spite of this, however, the G330 is still much better than an HDD and a fairly good performer for your grandparents or computer illiterate aunt.
The BIOSTAR G330 could be a decent OS drive or game drive, price permitting. Again, it did perform very well during PCMark 8’s normal run. For most people, a drive that performs well there should deliver perfectly acceptable performance that is similar to any other SSD. OS tasks aren’t that storage intensive once it is on flash, the same goes for gaming. Most hard drives will read at up to 200MB/s, but random and small file transfers slow HDDs down to a crawl. Luckily for an SSD such as this, although sequential write performance isn’t its strong suit, 90% of the time, it really doesn’t matter. What really matters is its small file transfer performance and fast sequential read performance. OS files and programs, game textures, and levels will all load faster and their appearance will be more fluid compared to hard drives. So, we will go ahead and say this is a fine choice for gaming. Most of the time we’re limited more by internet speed rather than HDD speed when it comes to downloading our massive game libraries nowadays anyways.
