The SSD Review The Worlds Dedicated SSD Education and Review Resource | 
High density, high performance, and reliability are three of the most critical factors in achieving data center excellence, and Solidigm may have delivered on all three. For years, the industry has pursued improved rack designs, with power efficiency and cooling at the center of that effort. While the Solidigm D7-PS1010 series has been available for some time, its newest E1.S form factor represents a significant advancement: it allows up to 32 drives to be installed in a 1U rack server and is the first SSD on the market to feature a single-sided cold-plate liquid cooling design.
Shown here are Solidigm E1.S form factor enterprise/data center SSDs. The top drive features a self-contained heatsink, while the bottom model is designed for liquid cooling. Although we do not have a liquid-cooled test environment, we evaluated both drives using our air-cooled test bench and can confidently say they are likely among the coolest-running solutions available today, especially given their density and compact form factor. The drives measure 120 mm long by 33 mm wide, with a height of 9.5 mm for the liquid-cooled version and 15 mm for the air-cooled model.
In testing both D7-PS1010 data center SSDs, we monitored the temperature during 128K pre-conditioning and found the air-cooled version to sit at 51°c while the liquid cooled version was less than 10°C higher, subject to the same fan-cooled test experience.
During our product briefing with Solidigm, they made it very clear that they weren’t in the business of providing cooling solutions, but that they expected a great deal of interest in their liquid cooled D7-PS1010.
The Solidigm D7-PS1010 is a PCIe 5.0 x 4 NVMe SSD that is available in 1.92, 3.84, 7.68 and 15.36TB sizes as well as U2, E3.s and now E1.s form factors. This SSD contains SK hynix 176-layer TLC NAND flash and this SSD is a 1-DWPD (drive write per day) SSD, whereas its 3 DWPD configuration is marketed as the D7-PS1030.
Listed performance speaks to up to 14.5GB/s read and 10.5GB/s write data throughput with up to 3300K IOPS. This SSD has a five year warranty which is adjusted to 3-years when used at 1.66 DWPD. Max lifetime endurance for the D7-PS1010 is 28PBW when using the 15.36TB version.
While the max active power draw is listed at 23/25W, this SSD can be fine-tuned for five adjustable power states from 5W to 25W.
