Hello. to answer your question(s), weread/write using laser technology. The write is via femto lengthed, multiple headed laser ablation, the read is via inexpensive led lasers. The read speed is comparable to mag tape (200+MB/sec), the write is not as fast, but definitely above 100 MB/sec. Yes, it means new equipment, BUT, it also means the end of data reduplication every 7 to 10 years. We believe cost will be similar to cloud storage.
