Intel DC S4500 / DC S4600 – SSD to store data / Blog company Intel / SurprizingFacts

Intel continues to move into a futile future. The new SSD series DC S4500 and DC S4600 are designed to replace the HDD in servers and storage systems. Performed using Intel 3D NAND technology of the second generation, SSDs have a capacity of up to 4 TB. Performance indicators – up to 72k / 33k IOPS for S4500 and 72k / 65k IOPS for S4600 (read / write, random blocks 4k).

The drives received a new SATA controller that provides up to 30% Performance gain on real mixed loads. The firmware update system allows you to do this automatically, without rebooting and loss of speed. In general, the annualized Failure Rate (AFR) for new SSDs is more than 3 times higher than for specialized HDDs. The number of read errors is 1 sector per 10 19 operations.

The new SSD series is parallel to the recently released P4500 / P4600 series with PCIe NVMe interface, so this step can be called evolutionary development. And then a number of interesting and principled innovations awaits us – about them briefly under the cut.

So the important changes in the SSD for data centers that are waiting for us in the near future:

  1. A new "ruled" form factor . Intel will move away from the traditional 2.5 "and 3.5" HDD versions – the heritage of HDD – and will move to flat and long constructs. This will increase the storage density and achieve unprecedented results – up to 1 Pb in one unit. In addition, this form factor is more convenient in terms of the geometry of PCI Express slots.
  2. Using Intel Optane technology . Intel Optane can be used not only with traditional HDD. Equipped with an Intel Optane cache block, SSDs will also work even faster.
  3. Dual Port SSD . Two SSD ports provide the redundancy and redundancy required for mission-critical tasks. Such SSDs will be available already in the third quarter of this year.
