At Micron Insight 2019, the company launched new NVMe SSDs. This is the Micron 7300 series of NVMe SSDs that are designed to be one step below the Micron 9300 series we used in platforms, e.g. for our AMD EPYC 7002 Series Rome Launch Coverage. It is also designed to be a step above the Micron 5300 SATA series in terms of performance. Overall, these SSDs are designed to help transition from SATA/ SAS hard drives and SSDs to NVMe.
Micron 7300 Series NVMe SSDs
Micron has two levels of these SSDs, the Pro and Max series. Like in other models, the Pro series is designed to have 1 DWPD for higher capacity, lower performance applications. The Max is designed as 3 DWPD for higher performance lower capacity applications.
Micron 7300 Pro Series
The Micron 7300 Pro series has three form factors. These are 7mm U.2 2.5″, M.2 80mm and 110mm (M.2 2280 and 22110.)
Capacities for U.2 drives range from 960GB to 7.68TB. Capacities for the M.2 drives range from 480GB to 3.84TB.
These drives are designed to have relatively high capacity. Perhaps the bigger impact is that their performance is significantly higher than SATA/ SAS SSDs, and sometimes as fast as entire arrays of SATA/ SAS SSDs. Offering bigger capacities means higher storage density.
Micron 7300 Max Series
On the 3 DWPD side, the Micron 7300 MAX NVMe SSD also comes in both 7mm U.2 form factors and M.2 2280 (80mm) sizes. A M.2 22110 (110mm) drive was not announced. Capacities for the U.2 drives range from 800GB to 6.4TB. The M.2 capacities are 400GB and 800GB in capacity.
The MAX series as a 3 DWPD drive is designed to be higher performance and much higher write speed drive than the Pro series. We are seeing a massive shift to NVMe with this generation, so we think these are strong offerings.
