Crucial 128G not software
Marked difference after I tore it up. Only a few times so far used but the difference looks to be a decisive change in characteristics for the better. The model is advertised "Slider", where there's a thick plastic sleeve integrated to slide over the unit and cover the male connection point. That sleeve acted for a sheath for handling the unit. I tore the sliding sheath portion off with stubby needle-nose pliers, breaking off pieces of the thick sheath's plastic without damaging the inner core stick plastic construct, top and bottom. The sheath's runners were deep in the inner portion's side channels, that are now exposed for the PCB within. Where the sheath formerly butted against the inner core at the connection appears to allow a few millimeters more metal connection exposure, now when inserted into a USB port. Then I deleted the partition, 16K sectors straight across 128G, split and created a 64G partition with 64K sectors, and recopied an existing 32G data on it. A huge difference in the "action" for how the computers pick it up. Its LED comes on, one longer strobe, followed by hardly a few blinking strobes, then stops with the data content identified and drive-mounted by the OS for near instant usage. Over the years I'd done a lot of copying then deletion of files with the prior format. Whether usage had accumulated to adversely affected reading the MBR, I don't know;- neither whether removing the sheath helped by getting a deeper USB connection insert, which wasn't cleanly constructed, anyway, as the inner core had some wobble on that sheath, I didn't like. A deeper connect also could imply wear at the contacts over a prior state of physicality, minus the sheath, that is since improved. Also looked at the Western Digital Sandisk 64G units, which performed better than expected for speed, on par with the Crucial. The Sandisks are much smaller and tightly constructed in metal casing;- Micro-designed being the engineered intent. Except they're hotter than hell, as soon as inserted, within under a minute rising in temperature to what feels approaching 140F. Didn't bother with a IR thermometer. That's also ambient operation with no read/write activity. Not cool. Possibly suited a powered hub, as I'm not sure I want the constant heat from power they're inefficiently drawing imposed on the MB and its USB support. A powered straight USB hub with 8-point ports, LEDs switches for turning individually ports on/off, is under $10/US. If Sandisk must impose itself, the memory irrespectively probably will last at 140F, better imposed on hubs than a critical MB pathway/supply support USB operations. Although the Crucial inner core handling is plastic, I can still pull to feel the end metal USB connection for a sense of temperature, which remains relatively cool. Those Sandiscs are way, way out there for comparative heat dissipation -- not quite blisterers but decidedly up and into hot territory. My 200W Class-D amp's output stage transistors run where they do when idling before kicking in a supplementary 12V fan (though not as hot as a Class A/B's 200W amp's vented transformers);- small microphone broadcasting predecessors to 12AX7 vacuum tubes in my preamps, (sold for headphone amps), the tubes run at temperatures where the Sandiscs are. |
