Two of the traces are sequential accesses, while two are 4K random accesses. for example, uses four different access traces for reads and writes over a configurable region size. ATTO does allow the visualization of change in transfer rates as the I/O size changes, with optimal performance being reached around 512 KB for a queue depth of 4 for both SSDs.ĬrystalDiskMark. Interestingly, at QD4, the ArmorLock SSD hits 1.01GBps for both reads and writes, while the G-DRIVE SSD hits 1GBps+ only for reads. ATTO benchmarking is restricted to a single configuration in terms of queue depth, and is only representative of a small sub-set of real-world workloads. Western Digital claims speeds of up to 1000 MBps for the ArmorLock NVMe SSD and 1050 MBps for the G-DRIVE SSD. ![]() Yet another use of these synthetic benchmarks is the ability to gather information regarding support for specific storage device features that affect performance. The results translate to the instantaneous performance numbers that consumers can expect for specific workloads, but do not account for changes in behavior when the unit is subject to long-term conditioning and/or thermal throttling. Unlike with CrystalDiskMark however, it's obvious that Synergy and the custom driver are actually doing something to improve performance, especially at low data sizes.Synthetic Benchmarks - ATTO and CrystalDiskMarkīenchmarks such as ATTO and CrystalDiskMark help provide a quick look at the performance of the direct-attached storage device. The only test to show a notable performance uplift was the random test with a high queue depth and thread count, which saw performance increase by roughly 25%.ĪTTO Disk Benchmark acts very similarly to CrystalDiskMark, only the queue depth is set for all data transfers (a depth of 4 in this case, which is the default) and it tests a wide range of data block sizes scaling from just 512 bytes to 64 megabytes (I cut out everything after 2MB for brevity however). When retesting with Synergy installed, not a ton changed for the P41 Plus in five of the six tests. However, there are some cases where a low queue depth will swing things in the 970 EVO Plus's favor, though not by much. The P41 Plus without any help from Synergy software is just a little faster than the 970 EVO Plus, probably due to a combination of using PCIe 4.0 rather than 3.0 and also having newer hardware. Scores shown are for read/write speeds, measured in MB/s. Solidigm makes the P41 Plus a compelling deal not just thanks to its low price and decent specifications, but also through its Synergy Toolkit application and custom driver support, something that pretty much no other company bothers with anymore. However, Solidigm isn't really a new company when Intel sold off its SSD division to SK Hynix, it was rebranded to Solidigm, and still advertises the popular budget 660p and 670p drives on its website.Īlthough the field is already crowded with cheap PCIe 4.0 SSDs, Solidigm's P41 Plus manages to stand out and proves to be a worthy successor to the 660p and 670p. There's a lot of brands in the SSD arena, from titans like Samsung to newcomers like Solidigm, which was founded in late 2021 and thus hasn't had much time to make a name for itself yet.
