Hello @sergeyk,

Thank you for your remarkable participation in Week 6 of the Steemit Learning Challenge Season 23. Your submission stands out for its unique historical perspective and exceptional technical depth. Here's your evaluation:

Task 1: HDD Structure and Operation (2/2)

Your historical analysis of hard drives, from floppy disks to modern technologies, is exceptional. You masterfully explained the evolution of rotational speeds (from 300 to 15,000 RPM), technological advances such as perpendicular recording, and historical limitations (CHS addressing, BIOS limitations). Photos of vintage hardware and your personal anecdotes about academic computing add invaluable value to your explanation.

Task 2: SSD Advantages (1.5/1.5)

Your SSD/HDD comparison shines with its authenticity and technical depth. You share your personal experience with early SSDs, present a comprehensive comparison chart, and accurately address the endurance/capacity tradeoff. Your insights into the mSATA/M.2 transition and the historical price/performance context are particularly valuable.

Task 3: Internal vs External Drives (1.5/1.5)

Your overview of external storage solutions, from 5.25" bays to modern USB 3.0 enclosures, is remarkable. You thoughtfully analyze the practical benefits and power requirements through the ages, and carefully document SATA-to-USB adapters. The quality of your documentation on historical hardware is impressive.

Task 4: Inspecting Your Drive (2.5/2.5)

Your technical demonstration is exemplary. The installation of an mSATA SSD with soldering modifications, the comparison of different interface adapters, and the detailed photos of portable storage configurations demonstrate exceptional craftsmanship. The documentation of capacities and interfaces is comprehensive.

Task 5: Analyze Drive Health (2.5/2.5)

You go far beyond simple SMART checks. The comparison of tools (SSD-Z, CrystalDiskInfo, Victoria), the historical context of diagnostic software, The examples of professional recovery software and the warning about responsible use of advanced tools demonstrate rare expertise. Your vintage hard drive collection is the icing on the cake.

Final Score: 10/10

Your submission is both an excellent response to the Week 6 challenge and a valuable archive of the history of storage technologies. You brilliantly combine unparalleled historical context, museum-quality hardware documentation, professional technical knowledge, and a perfect balance of theory and practice.

Suggestions:
A series on the evolution of storage technologies would showcase your unique historical perspective. A tutorial dedicated to your hardware modification techniques would certainly interest the community. Finally, a special post on your vintage hard drive collection would be fascinating.
