Read speed:
sequential read speed 10000 MB/s 14000 MB/s
random read speed 1500000 IOPS 2000000 IOPS

The Crucial P510 2TB and Lexar NM990 2TB differ in both their sequential and random read speeds. The Crucial P510 offers a sequential read speed of 10000 MB/s, while the Lexar NM990 outperforms it with a sequential read speed of 14000 MB/s. This makes the Lexar NM990 faster in sequential read operations by a noticeable margin.

In terms of random read speed, the Crucial P510 has a random read speed of 1500000 IOPS, while the Lexar NM990 reaches 2000000 IOPS, again showing a significant advantage for the Lexar in random access performance.

Overall, while both drives deliver high-speed performance, the Lexar NM990 shows higher read speeds in both sequential and random read tests compared to the Crucial P510.

Write speed:
sequential write speed 8700 MB/s 10000 MB/s
random write speed 1500000 IOPS 1400000 IOPS

The Crucial P510 2TB and Lexar NM990 2TB show some differences in write speeds. For sequential write speed, the Crucial P510 offers 8700 MB/s, while the Lexar NM990 is slightly faster with a sequential write speed of 10000 MB/s.

When it comes to random write speeds, both drives share the same figure of 1500000 IOPS for the Crucial P510 and 1400000 IOPS for the Lexar NM990, with the Crucial P510 again showing a marginal advantage in random write performance.

In summary, the Lexar NM990 leads in sequential write speed, but the Crucial P510 takes the edge in random write speed, though the difference is small.

The Crucial P510 2TB and Lexar NM990 2TB are similar in several key aspects but differ in some important areas. Both are M.2 NVMe SSDs with 2000GB of internal storage and PCIe 5.0 support. However, the Crucial P510 uses a Host Memory Buffer (HMB) for its SSD cache, while the Lexar NM990 is equipped with a DRAM cache, which may have implications for performance in certain use cases.

In terms of controller channels, the Lexar NM990 features 8 channels, offering potentially more parallelism, while the Crucial P510 has 4 channels. This could influence the overall speed and data management capabilities of the two drives. Additionally, the Lexar NM990 has a higher Terabytes Written (TBW) rating of 1500, compared to the Crucial P510's 1200 TBW, meaning the Lexar may endure slightly more write-intensive usage over its lifespan.

Both products offer a 5-year warranty and do not include an integrated heatsink or RGB lighting. The key differences here come down to the SSD cache type, controller channels, and TBW rating, with the Lexar NM990 slightly ahead in terms of durability and controller architecture.

Comparison Summary

This is a specification comparison between Crucial P510 2TB and Lexar NM990 2TB. Both products are M.2 NVMe SSDs with 2000GB of internal storage, use PCI Express (PCIe) version 5, and have a 5-year warranty. They also lack an integrated heatsink and RGB lighting. Key differences include that the Crucial P510 has a sequential read speed of 10000 MB/s and sequential write speed of 8700 MB/s, while the Lexar NM990 offers 14000 MB/s read and 10000 MB/s write speeds. The Crucial P510 uses HMB cache, while the Lexar NM990 uses DRAM cache. Additionally, the Lexar NM990 has 8 controller channels, compared to the Crucial P510's 4 channels, and its Terabytes Written (TBW) is 1500, higher than the Crucial P510's 1200.
