Solidigm’s new D7 series has been noticeably improved over the previous generation of PCIe 4.0 drives, including better performance in mixed and read-intensive applications. For example, compared to the P5510, Solidigm indicates an improvement up to 42% higher in random reads with 1.1 million IOPS and 17% higher in random 4K writes with 200,000 IOPS. Sequential performance is quoted at 7.1GB/s read and 4.2GB/s write.
This upgraded performance profile, coupled with its expanded capacity range, can translate into more cost-saving opportunities for organizations. For example, when looking at a 365TB configuration (via the 15.36TB model), Solidigm claims a 50% smaller physical footprint and a 44% reduction in overall power compared to the 8TB P4510.
The Solidigm P5520 also comes with a range of improved enterprise features, including support for multiple sector sizes (512/520/4,096/4,104/4,160 B), OPAL 2.0, configurable namespace locking, secure erase, improved telemetry logs (including intelligent error tracking and logging), dynamic multiple namespaces and device self-test.
Backed by a 5-year warranty, we will be looking at the 7.68TB U.2 P5520 in this review.
