SK hynix Platinum P41 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 Platinum P41 manages to exceed its rated sequential read speeds by a fair margin, but does not quite match its rated write speeds. Despite not quite matching write performance claims, the P41 still manages to turn in chart-topping sequential write performance, and is very close to the same on reads.
Performance improves ever so slightly on the larger CrystalDiskMark test. The improvement is not enough to catch up to the claimed 6500 MB/s write speed, but it does allow the P41 to extend its overall write speed crown over the rest of the competition.
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.
In ATTO read speed takes a small hit compared to CrystalDiskMark but still manages to meet its advertised performance as well as turning in a virtual tie with our other top-end PCIe 4.0 drives. Read speeds actually improve a bit versus CrystalDiskMark, and they remain the fastest sequential write speeds on the chart.
The P41 holds its ground in the larger ATTO test. Read speeds are still a tie with other top-end drives and write speed is still the fastest we have seen.
Anvil’s Storage Utilities
Anvil’s Storage Utilities is a comprehensive benchmark that gives us a very in-depth look at the performance of drives tested. This benchmark was run with both a 1GB and 8GB test size.
In Anvil, performance for the SK hynix Platinum P41 takes a small hit compared to the sequential-only tests we recorded in CDM and ATTO. While the P41 was the sequential write speed king in our previous tests, the write score in Anvil is much more down-to-earth. The P41’s scores are still fine, but it is in no way chart-topping like the CDM and ATTO results were.
The P41 barely loses a step in the larger Anvil test. Read score is now in second place on our chart, narrowly losing to the WD Black SN850, and write score is still OK.
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 SK hynix Platinum P41 turns in a great read score in AS SSD, landing at the top of my chart. Read score is also improved in AS SSD versus in Anvil, and the P41 lands a solid third place finish for writes.
Performance in the larger AS SSD test slips a small amount, which allows the SN850 to squeak out a read score win. With that said, the P41 results in AS SSD remain very strong.
SPECworkstation, thermals, and our conclusion are up next.
