The Zircon L1 Series is a solid-state drive in the M.2 2280 form factor, launched in February 2023. It is available in capacities ranging from 256 GB to 512 GB. This page reports specifications for the 256 GB variant. With the rest of the system, the Zircon L1 Series interfaces using a PCI-Express 3.0 x2 connection. The SSD controller is the MAS1102B-B1C from MaxioTech, a DRAM cache is not available. Zircon has installed 176-layer QLC NAND flash on the L1 Series, the flash chips are made by Micron. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The L1 Series is rated for sequential read speeds of up to 580 MB/s and 540 MB/s write; random IO reaches 58K IOPS for read and 62K for writes.
The SSD's price at launch is unknown. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. Zircon guarantees an endurance rating of 174 TBW, a good value.
