Solidigm SSD D5-P5430 Review: Speedy, Dense Data Center Storage
Solidigm SSD D5-P5430 Review: More Benchmarks And Our Conclusion
HD Tune Pro v5.75: Bandwidth & Latency
The Solidigm SSD D5-P5430 competes favorably with the other PCIe Gen 4 drives we tested, but it ultimately slots in just behind the D7-series in with both reads and writes. Latency is competitive as well, though it technically trailed the D7-series drives slightly overall.
CrystalDiskMark Storage Tests
CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. It provides a quick look at best and worst case scenarios with regard to SSD performance, best case being larger sequential transfers and worse case being small, random transfers.
Latency Under Load
For this next set of tests, we measured access latency at various queue depths with the same fully random IOmeter 4K access pattern (67% reads, 33% writes) featured previously, but while each of the drives was also under a sustained sequential write workload. A sustained sequential write across the entire volume was initiated, and when performance plateaued, access latency was measured with IOMeter using the 4K fully random access pattern running concurrently.
While under load, the Solidigm SSD D5-P5430's performance remains mostly consistent, with only a slight increase in latency under load. The Solidigm SSD D5-P5430 ends up leading at QD8 and QD16, but settles right in the mix with the D7-series drives in the other tests.
Solidigm SSD D5-P5430 Summary And Conclusion:
Solidigm is positioning the SSD D5-P5430 as a mid-range offering, tuned for read-intensive workloads, and our testing shows just that. The Solidigm SSD D5-P5430 competed well with the other PCIe Gen 4 drives, especially in terms of reads and when placed under higher loads, with more modest overall write performance.
The Solidigm SSD D5-P5430 15.36TB drive we tested put up competitive numbers across the board, in-line with its rated specifications. We haven't been able to find them listed for sale anywhere just yet since they're brand new, so calculating street prices isn't possible at the moment. However, Solidigm tells us they expect pricing to settle 10-15% below Solidigm D7 Standard Endurance (SE) products of the same capacity. For reference, Solidigm SSD D7-P5520 drives can be found for approximately $0.08 - $0.10 per gigabyte as of this writing, which isn't much higher than some of the better consumer-class drives currently on the market.
The Solidigm SSD D5-P5430 offers competitive overall performance in read-centric workloads, with excellent latency characteristics, leading-edge features, a solid warranty, and what will likely be highly competitive pricing. With all of that in mind, its easy to recommend the Solidigm SSD D5-P5430 if it's the right fit for your data center storage environment.
