Micron's first enterprise NVMe SSD, the 9100 Series, reach full capacity at 3.84TB. Micron's sophomore release increased capacity to 11TB but the read and write performance was imbalanced, like most enterprise SSDs still shipping today. Today we will look at Micron's third generation enterprise SSD series with increased capacity and a balanced approach to performance that enables consistent performance for all workloads.
The 9300 Series isn't just about reaching new performance heights. Micron added new tricks to the series. System administrators can expect more than a 28% improvement in power efficiency, larger sizes to reduce rack/floor space, and 32 NVMe namespaces so you can maximize the drives with parallel sessions.
The best part is the robust deliver that Micron implemented with the 9300 Series. It breaks down into two performance tiers and six capacities so you don't have to pay for more than you need.
As mentioned, the 9300 Series breaks into two groups, the PRO models for more restrained enterprise workloads and the MAX models for stressful write-intensive workloads. Our testing today will show the differences between the two in a number of workloads so you can easily see where the two stand.
Undoubtedly, there will be some references to the closely related Memblaze PBlaze5 916. Micron offers a high capacity tier that Memblaze doesn't. We also expect to see some differences in firmware as well as pricing in the different markets.
Looking at the capacity first, there are really only three main starting points that break down into six user addressable sizes. The 9300 MAX reserves more flash for background activities that provide increased performance for data written as well as increased endurance. The 9300 PRO models give some of that reserved capacity back but still reserves enough space to keep the 64-layer 3D TLC memory happy. If your application requires more overprovisioning, you can use the Flex Capacity feature in Storage Executive to fine tune the drives.
Pricing, Warranty, and Endurance
We don't have pricing details at this time, but the Micron 9300 Series is currently in mass production. The series comes with a 5-year warranty and ample endurance measured in the petabyte range. The chart above lists the endurance by model with the highest coming in at 74.7 petabytes.
Accessories and Software
The Micron 9300 Series supports Micron's Storage Executive software with both Windows and Linux versions available.
A Closer Look
Both the 9300 PRO and 9300 MAX SSDs appear identical other than a slight change to the product label. We have a 9300 PRO sample from Micron and use it to test the performance of both the PRO and MAX by changing the overprovisioning by shrinking the user-exposed volume.
The series only ships in a 15mm z-height form factor.
