ASIC Evaluation Report
Flagship bench assessment for second-generation ASIC miners — hashrate verification, hashboard health, and a written report for fleet decisions.
Guro-gu, Seoul — Est. 2019
Second-Gen ASICs Still Running in 2026
Filesycamoreway publishes field-tested reviews of mining equipment at 0.05 TH/s and above. We assess hashboards, power draw, and residual output for operators deciding whether to keep, relocate, or retire second-generation units.
What We Assess
Hardware That Still Earns Its Rack Space
Our reviewers work directly with Antminer S19 variants, Whatsminer M30S units, and other second-generation ASICs commonly found in Korean hosting facilities. Every report covers thermal behaviour, firmware state, and realistic hashrate under local power tariffs.
Residual Value Assessment
Documented resale value guidance for retiring second-generation ASIC fleets based on measured output and domestic market conditions.
Thermal & Power Audit
On-site thermal mapping and circuit loading review for hosting facilities running second-generation ASIC racks in the Seoul area.

Recent Field Notes
Cooling Layout Mistakes in Narrow Seoul Row Houses
Three recurring airflow errors we document during thermal audits of second-generation ASIC racks in converted row-house basements.
M30S++ Fan Replacement: What We See in Workshop Batches
Whatsminer M30S++ units from 2023 batches often need fan swaps by year three — notes from our Guro spare-parts shelf.
Operator Voices
What Hosting Clients Say
We brought twelve S19j Pro units to Filesycamoreway before renewing our Guro lease. The report flagged three hashboards running 4% below spec — enough to justify a partial swap rather than a full fleet write-off.— Min-jun H., small-scale hosting operator, Seoul
The thermal audit was thorough, though scheduling took an extra week because our basement intake fans were still running during the visit. Fair enough — they wanted accurate readings.— Yuna K., co-location client, Incheon
