Hello all, Today, I got my ssd disk (Crucial 32 Gb "old" sata 3Gb/s) with USB box. As expected, my pbx running with my SD card could not be stopped (lots of "error -110" -- problems with the speed of writing to SD card). I could recover the FS on the ssd drive. Of course, I do not have the "true"

Another intersting behaviour of the SD, USB and SSD also is the write deadlocks : see few attempts to get explain at my fastbench page [1]. Regards, [1] https://doukki.net/doku.php?id=wiki:tutoriels:fastbench Le 24/08/2012 14:42, Laurent Lesage a écrit : > Thank you all for your opinion and expe

Thank you all for your opinion and experiences. I confirm that I got nearly all the problems described by some of you : -some SD card work, some don't. -when they work, they have slower access than USB sticks. -when they works, it happens that they suddenly become "read-only". The system continue

Beware of heat. Do not obstruct the vents. Free air on 5.5 sides (rubber feet giving clearance on the bottom) at 25C might not be cool enough. Use a separate power supply for USB devices, especially rotating harddrives. Run "lsusb -v" and check the MaxPower ratings; some flash memory devices dr

There have been persistent reports of flaky results with SD cards on Sheeva (and other) Plug devices. The best theory I've heard so far is that the SD interface hardware/software in the Plugs is vey picky about the specs and timing of the SD card interface. Many people have no problems for ye

Hello again, just an idea : I can find cheap "old SATA 3G" SSD disk + usb box. Should it be a good solution? For, say, 50 $, I can get 32 GB and those SSD seems much more reliable. I'm interested in your opinions (and in answers to my first post!) thanks ahead -- Laurent Lesage Laurent Le
