A few months ago we reviewed the Solidigm P41 Plus NVMe SSD from this company that was created when SK hynix took over Intel’s NAND/SSD business. The P41 Plus was a budget consumer SSD with QLC memory, while they recently released the P44 Pro as a step up and based on the SK hynix Platinum P41 design. I tested the Solidigm P44 Pro 1TB and 2TB PCIe 4.0 NVMe SSDs under Linux for excellent performance.
Solidigm P44 Pro solid state drives currently come in 512GB, 1TB and 2TB capacities using the SK hynix Aries controller, SK hynix LPDDR4 DRAM and SK hynix 176L TLC memory, the 1TB and 2TB models are rated for up to 6500MB/s sequential write and up to 7000 MB/s sequential reads. With two top-of-the-line P44 Pro drives, the random read IOPS is 1.4 million and the random write IOPS is 1.3 million.
So far, the Solidigm P44 Pro 1TB drive sells for around $130 and the 2TB version for around $209~219, which is quite competitive with the other PCIe 4.0 M.2 2280 NVMe SSDs from the tips. It’s also worth noting that the P44 Pro is stocked by a number of popular online retailers with relatively high availability, it seems.
It’s no surprise that the Solidigm P44 Pro SSD runs Linux with ease. There are no compatibility issues to note or any other issues with the SSDPFKKW010X7 or SSDPFKKW020X7. As a detail for Linux drive setup: Solidigm currently does not support firmware upgrade via LVFS/Fwupd (other than keeping the Intel 670p firmware in LVFS), unfortunately, but at least its firmware can be upgraded using its USB-bootable firmware updater and storage. Hopefully, Solidigm will add LVFS/Fwupd support in the future to make it easier to update SSD firmware on Linux like it was during the Intel SSD era.
From an Intel Core i9 13900K “Raptor Lake” test system running Ubuntu 22.10 with Linux kernel 5.19, a series of Linux storage benchmarks were run on the Solidigm P44 Pro and other consumer PCIe 4.0 NVMe SSDs.
Other NVMe SSDs recently tested on Linux for this comparison include:
-WD_BLACK SN850 1TB
-WD_BLACK SN850X 1TB
-Samsung 980 PRO 2TB
-Samsung 990 PRO 1TB
– Sabrent Rocket 4.0 Plus 1TB
-Solidigm P41 Plus 1TB
-Solidigm P41 Plus 2B
-Solidigm P44 Pro 1TB
-Solidigm P44 Pro 2TB
With SQLite and other select databases, Samsung’s 900 series SSDs still have major problems with Linux… This has been a consistent problem on all Samsung SSDs I’ve tested over the past year or two when using the EXT4 file system in tandem. . The Solidigm P44 Pro SSDs performed well and performed comparably to the benchmarked WD_BLACK SN850/SN850X SSDs.
With FIO at least the Samsung 980/990 PRO drives show no performance anomalies under Linux, but in any case the performance of the Solidigm P44 Pro was fantastic with the 1TB and 2TB drives outperforming the Samsung 980/990 PRO and the WD_BLACK SN850 series for performance 4K random read on Linux.
However, with 4K random write performance, the P44 Pro units were not as competitive there. The P44 Pro SSDs were a significant step up from the P41 Plus drives and just behind the Samsung 980 PRO, but behind the latest Samsung 990 PRO and WD_BLACK SN850X drives for random write performance.
Sequential read and write performance of the Solidigm P44 Pro SSDs was excellent and fell just short of their rated read/write speed. everything is there and great prices for Solidigm P44 Pro NVMe SSD.
DBench is another case like SQLite, where Samsung SSDs perform extremely poorly on Linux, while Solidigm P44 Pro drives offer performance comparable to WD_BLACK SN850 and P41 Plus drives.
For those looking to run their own MySQL/MariaDB database server on some cheap consumer units for test/development or SOHO type deployment purposes, the performance of the Solidigma P44 Pro was good and just behind the WD_BLACK series SN850. Again, the Samsung 980/990 PRO units consistently perform poorly on these database workloads on Linux.
The performance of the Solidiigm P44 Pro with PostgreSQL was also competitive with the popular WD_BLACK SN850 series SSDs.
Overall, the Solidigm P44 Pro series performed well on Linux and generally offered competitive performance to the WD_BLACK SN850/SN850X series at a good price. The Solidigm P44 Pro drives also coped well with database workloads under Linux, unlike the Samsung 900 series drives which showed unusually poor performance under such conditions.
