Lexar introduces two new PCIe 5.0 NVMe SSDs that push sequential read speeds to 14,000MB/s, giving users a faster option for high-end PC builds. These drives arrive just in time for Amazon Prime Day, offering immediate access to next-generation storage for those upgrading their systems. The NM990 and Professional NM1090 PRO cater to different performance tiers, ensuring buyers can choose between mainstream and professional-grade hardware.
Professional and mainstream models launch July 7 in Japan
The Professional NM1090 PRO targets users who need consistent high-speed performance for demanding workloads. It features a 6nm controller and 232-layer 3D TLC NAND flash memory to handle heavy data loads. This model includes a dedicated DRAM cache to manage data efficiently during intense read and write operations. These components help maintain speed stability when transferring large files or running multiple applications simultaneously.
Spec comparison
| Spec | NM1090 PRO | NM990 |
|---|---|---|
| Sequential Read | 14,000MB/s | 14,000MB/s |
| Sequential Write | 13,000MB/s | 11,000MB/s |
| Cache | DRAM | HMB |
| NAND | 232-layer 3D TLC | 232-layer 3D TLC |
| Warranty | 5 years | 5 years |
In contrast, the NM990 serves as a mainstream alternative that relies on Host Memory Buffer (HMB) technology instead of a dedicated DRAM cache. Both drives share the same maximum sequential read speed of 14,000MB/s, but their write speeds differ based on capacity. The NM1090 PRO reaches 13,000MB/s on larger capacities, while the NM990 tops out at 11,000MB/s. Random read and write performance also varies between the two, with the professional model offering higher IOPS for smaller file operations.
Lexar offers both models in 1TB, 2TB, and 4TB capacities to suit different storage needs. The 1TB version of the NM1090 PRO provides 700 TBW of endurance, while the NM990 offers 750 TBW for the same capacity. Both drives come with a five-year warranty, providing long-term reliability assurance for buyers. Special Amazon Prime Day pricing begins on July 7, 2026, in Japan, allowing early adopters to secure these drives at a discount.
We looked at SanDisk Optimus GX PRO 8100 2TB Review earlier while tracking Lexar launches. These models highlight the competitive landscape of PCIe 5.0 storage where speeds continue to climb. Lexar's new releases add to the growing list of high-performance NVMe drives available in the market. Buyers should check the specific capacity and cache type that best fits their workflow requirements before purchasing.
