Shulou(Shulou.com)11/24 Report--

CTOnews.com Solidigm, a NAND flash solutions provider, today announced the launch of its first ultra-high-speed, single-layer cell (SLC) solid state drive D7-P5810 for the data center market.

Solidigm D7-P5810 hard drive attached to IT Home is described as follows:

The D7-P5810 uses Solidigm's proven 144-layer 3D NAND media and is a PCIe 4.0 product.

A new addition to Solidigm's high-performance D7 family, the D7-P5810 is designed for high durability and extreme write-intensive workloads. This Ultrafast Storage Class Memory (SCM) SSD provides up to 50 writes per day for random writes and up to 65 global writes per day (DWPD) for sequential writes. Up to 2x performance improvements in caching, HPC, data logging, logging, etc. compared to comparable products, and more importantly, at less than 20% of the cost of non-NAND SCM technology.

The D7 -5810 is ideally suited as an accelerator for high-density storage capacity tiers such as QLC SSD storage and offers significant advantages for the following use cases:

Metadata/logs: Put performance-sensitive data such as metadata or logs in SLC SSDs to speed up system performance. For example, SLC SSDs are used in dedicated pre-written logs in Ceph clusters.

Cache: SLC SSDs can act as write buffers or caches to help eliminate performance bottlenecks, significantly improve application performance, and improve TCO.

Tiering: Data is written to SLC SSDs first, resulting in faster commit speeds and subsequent read speeds. After the data is cooled, it is aggregated, compressed, and written in bulk to the underlying high-capacity QLC hard disk (such as Solidigm D5-P5336), thereby achieving higher storage space efficiency on the media. In addition, write shaping software such as Cloud Storage Acceleration Layer (CSAL) provides a further solution that enables QLC SSD's value in terms of density, TCO, and sustainability to be reflected in more workloads.

The D7-P5810 is now available in the 800GB (U.2 15mm form factor) version. The 1.6TB version will be available in the first half of 2024.
