Cerabyte has unveiled a detailed roadmap for its Ceramic Nano Memory archival storage system, promising a cloud-based platform capable of storing over 100 PB per rack by 2030. The company expects data transfer speeds to climb above 2 GB/s and the time to first byte to fall below 10 seconds, a dramatic improvement over its current pilot system, which delivers just 1 GB per rack, 100 MB/s throughput, and a 90-second access time. The initial pilot, running through 2026, validates the 1 PB per rack design. A mid-cycle refresh around 2027-2028 will boost rack density into the double-digit petabyte range, halve access times, and more than double throughput. By 2029-2030, Cerabyte aims to reach its full 100 PB capacity, sustain transfer rates exceeding 2 GB/s, and reduce access latency to under 10 seconds. Cerabyte's approach relies on 100 µm-thin glass panels coated with a 10 nm ceramic film. Data are inscribed by etching microscopic holes in the ceramic layer using a femtosecond laser, creating patterns that a high‑resolution camera can read.
Multiple 9x9 cm tablets fit into cartridges similar in size to magnetic tape, and robotic arms handle all media swapping. Financially, Cerabyte projects that the total cost of ownership will decrease from approximately $7,000-$8,000 per PB-month today to just $6-$8 per PB-month by 2030. Supporters include Pure Storage, Western Digital, In-Q-Tel, and the European Innovation Council's Accelerator fund. To date, the startup has secured roughly $10 million in seed financing, along with more than $4 million in grants. Compared with traditional tape libraries, Cerabyte's system offers at least twice the bandwidth, a lifespan exceeding 100 years versus tape's 7-15 years, and half the cost per terabyte. Additionally, the company envisions adopting helium-ion beam writing by 2045 to shrink bit sizes from approximately 300 nm to 3 nm, a change that could increase per-rack capacity into the exabyte range.
