Just checked with SH SYS, it s been up for 224 days straight with a fair amount of daily activity and no noticeable degradation in performance. Runs more reliably than my AXP hardware. FWIW YMMV. And 8GB SD cards are now about $5 on AMZN. Best of luck, I can second that, HPIVAX has been up for like 18 months, no problems whatsoever. Sampsa
