Solidigm's D7-PS1030 6.4TB is our current overall enterprise SSD performance champion. This 3-DWPD (Drive Write Per Day) mixed workload specialist is an absolute juggernaut as it relates to mixed workloads. Our testing clearly shows that nothing flash-based currently in circulation can match its mixed workload performance.
The D7-PS1010 was launched alongside the D7-PS1030, and it is intended to fill the role of mainstream data specialist designed to accommodate read-intensive 1-drive write per day (DWPD) workloads. Both models are available in 15mm U.2 and 7.5mm E3.S form factors. Today, we have in hand Solidigm's highest spec'd, in terms of 4K random read performance, capacity point Gen5 SSD, the 3.84TB PS1010 U.2 SSD.
This SSD continues what we saw from its 3-DWPD sibling back in August 2024, in that it is one of only two PCIe Gen5 SSDs we've encountered that can deliver and even exceed its maximum advertised random read throughput at QD512. This means that Solidigm's latest and greatest inherently have a superior read performance curve over anything else we've come across.
One final note for those of you who may not know the origins of Solidigm and why the seemingly fledgling company is already delivering more than its competition. SK hynix is the parent company of Solidigm, having acquired most of Intel's SSD business and the Dalian NAND flash manufacturing facility in China on December 29, 2021. With the acquisition, SK hynix instantly became a major player in the enterprise storage business. So, what was Intel storage, and everything that made Intel storage one of the biggest players in the enterprise SSD space is now Solidigm.

Prior to the AI revolution, datacenter SSDs' normal operating range would typically never exceed QD32. With AI data pipeline storage being directed by GPU, high queue depth performance has become paramount. Queue depths in the thousands are now commonplace, which is why we've changed our test platform, methodology, and operating system. Our charted upper queue depth range has been revised from QD256 to QD4096 for random data and up to QD1024 for sequential testing.
Testing Methodology
TweakTown strictly adheres to industry-accepted Enterprise Solid State Storage testing procedures. Each test we perform repeats the same sequence of the following steps:
- Secure Erase SSD
- Write the entire capacity of SSD 2x (2 loops) with 128KB sequential write data, seamlessly transition to the next step (sequential testing skips step 3)
- Precondition SSD by filling the drive twice with 4K or 8K random writes
- Run test-specific workload with a 30-second ramp up for 5 minutes at each measured Queue Depth, and record average result

Benchmarks - Sequential
128K Sequential Write/Read

We precondition the drive using 100 percent sequential 128K writes at QD256 using 1-thread for 2-drive fills, receiving performance data every second. We plot this data to observe the test subject's descent into steady-state and to verify steady-state is in effect as we seamlessly transition into testing at queue depth. A steady-state is achieved after 1-drive fill. Average steady-state 128K sequential write performance at QD256 is approximately 8,400 MB/s.


Solidigm specs its D7-PS1010 3.84TB SSD as capable of delivering up to 8,200 MB/s 128K sequential write throughput. We are getting up to 8,600 MB/s, so factory spec seems to be on the conservative side. This is the highest 128K sequential write throughput we've ever extracted from any 4TB-class SSD. Impressive.


Here the drive is factory spec'd for up to 14,500 MB/s 128K sequential read throughput. We are hitting up to 14,866 MB/s which also happens to be a new lab record for this performance metric. In terms of its performance curve across all measured queue depths, we prefer what the 6.4TB PS1030 is dishing out.
Benchmarks - Random
4K Random Write/Read

We precondition the drive using 100 percent random 4K writes at QD256 for 2-drive fills, receiving performance data every second. We plot this data to observe the test subject's descent into steady-state and to verify steady-state is in effect as we seamlessly transition into testing at queue depth. A steady-state is achieved after 1-drive fill. Average steady-state 4K random write performance at QD256 is approximately 320K IOPS.


Our 3.84TB contender is rated at up to 315K for 4K random write IOPS. We are getting up to 322K, so again, pretty much spot on. As the chart demonstrates, our test subject is very much intended for read-intensive applications.


Performance here is exactly where the drive is designed to deliver. Factory spec here is up to 3,100K IOPS at QD512. We are getting 3,271K IOPS at QD512 with our configuration, which happens to be a new high mark for any SSD we've tested. Our 3.84TB test subject's performance curve is the second-best we've encountered to date. Here again, we prefer the performance curve of its higher-capacity sibling, the PS1030 6.4TB.
4K 7030


Here our 3.84TB contender is rated at up to 729K IOPS for a 4K 7030 random mix. We are getting up to 762K with our configuration. Its low queue depth performance here is among the best, as is its high queue depth performance, however its performance at midrange queue depths is somewhat lackluster.
4K 5050


As we add more programming into the mix, naturally, our read-intensive specialist takes another performance hit.
8K Random Write/Read

We precondition the drive using 100 percent random 8K writes at QD256 for 2-drive fills, receiving performance data every second. We plot this data to observe the test subject's descent into steady-state and to verify steady-state is in effect as we seamlessly transition into testing at queue depth. A steady-state is achieved after 1-drive fill. Average steady-state 8K random write performance at QD256 is approximately 160K IOPS.


We expect 8K random to track pretty much the same as 4K random here, just at a lower IOPS rate because it's moving twice the amount of data. Factory spec here is up to 157K IOPS. We are getting up to 170K IOPS. Interestingly enough, QD1 is where we are seeing the most throughput. We've not seen a performance curve quite like this before. At QD1 our test subject is delivering the third highest throughput for any flash-based SSD we've tested to date.


Here the drive is factory spec'd for up to 1,550K IOPS. We are getting up to 1,674K IOPS, so that's great. Additionally, its performance curve is among the very best we've encountered.
8K 7030


8K 7030 is representative of a common database workload. Here the drive is factory spec'd for up to 364K IOPS. We are getting up to 383K IOPS. While it does do very well at QD1-2, it's obvious from this chart why a higher capacity 1-DWPD SSD or a 3-DWPD SSD is better suited for this role.
8K 5050


As expected, our read-intensive contender doesn't fare so well in a write-intensive environment.
Final Thoughts
At the 3.84TB capacity point, Solidigm's D7-PS1010 can deliver unmatched 4K random and 128K sequential read performance for a 4TB-class SSD, making it an ideal choice for read-intensive applications. However, as we mix in more programming, the drive starts to lag behind some of its competition. Some of this is due to its capacity, some due to its architecture; however, in ALL instances, the drive performs above the given factory up to performance metrics.

Based on its read prowess, consistency, and the rare ability to deliver exactly as advertised, we award Solidigm's 3.84TB D7-PS1010 SSD our highest award. Editor's Choice.
