Solidigm releases ultra-high-speed SLC SSD tailored for the data center market
Solidigm announced the debut of its premier ultra-high-speed SLC SSD tailored for the data center market: the D7-P5810. This device incorporates Solidigm’s tried-and-true 144-layer stacked 3D NAND, interfaced through PCI-E 4.0.
As the crowning member of Solidigm’s high-performance D7 series, the D7-P5810 is meticulously crafted for exceptional durability and intense write-centric workloads. Facing random data writes, it can deliver 50 daily full-drive writes, and when catering to sequential data, it boasts up to 65 DWPD. Compared to its contemporaries, it promises a performance boost of up to twofold in aspects such as caching, high-performance computing, data logging, and journaling, all the while requiring less than 20% of the cost of non-NAND SCM technologies.
The Solidigm D7-P5810 is now available with a capacity of 800GB, housed in a U.2 15mm form factor. Its continuous read and write speeds are 6400MB/s and 4000MB/s, respectively, with peak random read rates of 865,000 IOPS and maximum random write speeds of 495,000 IOPS. A 1.6TB variant is slated for release in the first half of 2024.
The Solidigm D7-P5810 is supremely suited as an accelerator for QLC SSDs, bestowing distinct advantages for the following scenarios:
Metadata/Logging: Positioning performance-sensitive data such as metadata or logs within the SLC SSD augments system agility. An exemplar use-case would be employing the SLC SSD for dedicated write-ahead logging in a Ceph cluster.
Caching: As a write buffer or cache, the SLC SSD serves to eradicate performance bottlenecks, significantly amplifying application prowess and refining the TCO.
Initiating data writing in the SLC SSD results in accelerated commit and subsequent read speeds. As data cools, it’s subsequently aggregated, compressed, and batch-written into the high-capacity QLC drive beneath, realizing enhanced storage space efficiency on that medium. Moreover, software solutions like cloud storage acceleration layers further optimize write shaping, accentuating the value of QLC SSDs in aspects of density, TCO, and sustainability across an expanded spectrum of workloads.
