- INDOGRIT N3X SSD offers 50 DWPD resistance, but costs more than typical business units
- Built for storage in cache, inference and workloads that punish ordinary SSDs
- It runs completely in SLC mode, sacrificing the capacity of serious performance gains
The Indogrit N3X SSD presents a high strength storage solution aimed at business workloads with extreme writing demands.
Presented in Computex 2025, and with the second generation XL flow of kioxia that operates in SLC mode, the unit is designed to deliver 50 unit deeds per day (DWPD) for five years, far exceeding the resistance of typical business SSDs.
This level of durability is impressive, but also raises questions about the cost of the device and if its performance will justify the expected premium.
SCM Roots and a specialized architecture
In the heart of the N3X is the memory of the storage class (SCM), a memory level designed to close the performance gap between DRAM and Nand Flash.
When used in SLC mode, Kioxia XL-Flash functions as a type of SCM, promising ultra-low latency and high resistance.
Unlike standard NAND, which stores multiple bits per cell, operate XL-Flash in SLC mode prioritizes speed and reliability on capacity.
This design choice closely reflects the original objectives of the Optana now discontinued of Intel, positioning the N3X as a potential successor in that specialized niche.
While SCM technologies such as XL-Flash are not new, they are still relatively rare due to their high cost and specialized applications.
The use of PCIE 5.0 IG5669 controller, with NVME 2.0 support, allows impressive performance claims: up to 14 GB/s reading and 12 GB/s of writing speeds, together with 3.5 million random reading IOP.
The latency is where the N3X stands out particularly: read latency under 13 microseconds and write a latency as low as 4 microseconds.
If constantly achieved, these figures would place the N3X between the fastest SSDs in development.
The impulse is marketed for workloads that involve sustained deeds, computing in memory and real -time inference, areas where traditional SSDs often fight with latency and wear.
However, the decision to operate completely in SLC mode significantly reduces the available capacity, resulting in smaller drive sizes and a higher gigabyte cost.
While the impulse is offered in capabilities ranging from 400 GB to 3.2TB, these do not reach what is expected of the largest SSDs of today.
Although the N3X has many of the technical qualities of the best portable SSD, it is not intended for conventional use.
Its dependence on SCM architecture, while allowing exceptional performance, firmly places it in the domain of niche business implementations.
