Predator GM7 1TB Performance Testing
We test using both the default smaller test size as well as larger test sets on our benchmarks. This allows us to see the difference between lighter and heavier workloads.
CrystalDiskMark is used as a basic starting point for benchmarks as it is something commonly run by end-users as a sanity check.
The Predator GM7 1TB does well in CrystalDiskMark, coming out on the top of my chart for read speed and second place for writes. The rated specs are 7200 MB/s read and 6300 MB/s write, and the GM7 exceeds those in read speeds and comes close to the line in writes.
In the larger CrystalDiskMark test, writes hold strong and remain above the GM7’s rated spec. Sequential write speed takes a minor tumble, which is likely due to the DRAM-less nature of the drive. With that said, the result remains respectable and in line with plenty of other drives on my chart.
ATTO Disk Benchmark
The ATTO Disk Benchmark has been a staple of drive sequential performance testing for years. ATTO was tested at both 256MB and 8GB file sizes.
The GM7 has a much poorer showing in ATTO. Read speed remains strong and virtually tied for the top of the chart, but write speeds take a precipitous tumble. To the GM7’s credit, the write speeds are at least consistent rather than wildly variable, but they are nowhere near the 6300 MB/s rating.
The larger ATTO test has the GM7 continuing the trend of good read results with sub-par write results.
Anvil’s Storage Utilities
Anvil’s Storage Utilities is a comprehensive benchmark that gives us a very in-depth look at the performance of the drives tested. This benchmark was run with both a 1GB and 8GB test size.
In Anvil, the GM7 has somewhat of a return to form for write performance. While it is not at the top of the charts for either reads or writes, it is a decent performer and easily top half of the chart for either.
The larger Anvil test has the GM7 squeak out a read score victory over the rest of my chart while remaining more middle-of-the-pack in write score. Still, the GM7 is much better off in write performance in Anvil than it was in ATTO.
AS SSD Benchmark
AS SSD Benchmark is another good benchmark for testing SSDs. We run all three tests for our series. Like other utilities, it was run with both the default 1GB as well as a larger 10GB test set.
The Predator GM7 turns in a similar-feeling result in AS SSD as it did in Anvil, with results for both read and write scores that are good but not chart-topping.
The larger AS SSD hits the GM7 a bit harder on the write results than many of the other drives on my chart. Read score remains high, but the write score drops much closer to the bottom of the chart.
SPECworkstation, thermals, and our conclusion are up next.
1tb = $70 on amazon
Since when is “Voltage” measured in Watts?
I agree, the specifications table should replace “Voltage” with “Power Consumption” or something similar.
altmind, the $70 drive is the GM7000 which is a different model.
Josef and mariush,
I agree! But I didn’t make the specs table; comes right from the Predator website.
How relevant is DRAM cache for a Linux system that uses F2FS ?
