Architecture choice

Prebuilt vs DIY

A business should not choose DIY solely to save money. Once compatibility testing, assembly labor, qualification media, and downtime exposure are counted, a warrantied $350–$550 prebuilt tower can cost less than a custom system.

Equipment decision flow Decision path recommending a warrantied prebuilt tower as the primary machine, with DIY one-box as backup and split enclosure only as a last resort. Blueprint decision path Need revenue-ready production? Start here → PRIMARY: warrantied 1-to-7 tower Produplicator or PlexCopier/Vinpower BACKUP: DIY one-box After workflow is proven ACCESSORIES now Printer · media · spare writer LAST RESORT: split 5+4 Only if shipping/size forces it Launch package QC process · emergency burner UPS · documented settings
Use DIY after production has started — then you know preferred controller, writer, media, speed, and service procedures.

Recommended primary

Prebuilt 1-to-7

  • Hours to production readiness
  • System warranty and vendor support
  • Lowest startup engineering risk
  • Recognized resale value
  • Best when delivered for ~$305–$550
Best backup

DIY one-box

  • Short internal SATA only
  • One PSU and one power switch
  • Excellent repair flexibility
  • Closest to Microboards QD-127 layout
  • Fabricate bulky chassis locally
Last resort

DIY split 5+4

  • Reduces shipped piece size
  • Requires four separate remote channels
  • Needs synchronized dual PSUs
  • Highest startup and failure risk
  • Boxes must stay side-by-side

What “daisy chain” actually means

One controller spanning multiple small enclosures is not true SATA daisy-chaining. Every remote drive still needs its own point-to-point data cable. Ordinary internal SATA is intended for runs no longer than 1 meter.

Design One master for all drives? One cable between boxes? Controller in every box? Recommended?
One controller + remote SATA drives Yes No — one cable per drive No Only short, fixed, side-by-side
Microboards NET-style chain Yes One control cable per tower link Yes Proven, hard to clone from generics
Independent small duplicators No unified job No Yes Reliable, but start each unit separately
PC + powered drive boxes Yes, via software Possibly USB/eSATA No standalone controllers Flexible, not a standalone appliance
  • Microboards NET designates towers as First, Middle, or End with OUT→IN control links.
  • Every NET tower has its own AC power; Microboards advised ≤ 4 towers on a 15 A circuit (~3 A each).
  • Recreating that proprietary bus is unnecessary for seven targets — use direct controller channels.
