| 00:43 | dv_ | MMlosh: any progress on the sata speed ? |
| 00:44 | MMlosh | it stayed at 68MBps = 544mbps during the transfer, as I said earlier |
| 00:51 | TrevorH1 | esata attached here: Timing buffered disk reads: 302 MB in 3.00 seconds = 100.64 MB/sec |
| 00:52 | dv_ | TrevorH1: what did you use for measuring? |
| 00:52 | dv_ | copied with dd ? |
| 00:52 | MMlosh | I am currently trying to copy a file using a faulty SD card reader using ddrescue |
| 00:52 | MMlosh | it's fun |
| 00:52 | TrevorH1 | that's hdparm |
| 00:53 | dv_ | i dont know which sata version the cubox uses |
| 00:53 | dv_ | but even sata 1 can theoretically do 150 MB/sec |
| 00:53 | dv_ | it would be interesting to see what the cubox can do with an SSD |
| 00:54 | TrevorH1 | ata1: SATA link up 3.0 Gbps |
| 00:55 | TrevorH1 | that's what mine is |
| 00:56 | MMlosh | ouch.. but I think I got my 4GB file out of the card.. |
| 00:56 | MMlosh | (I had to press the card rather strongly inside the reader for the whole time) |
| 00:56 | MMlosh | I remember mine also saying 3Gbps |
| 00:58 | MMlosh | my hdparm -t says 174 MB in 3.00 seconds = 57.99 MB/sec |
| 00:59 | MMlosh | it could simply be the drive. It's noisy and the capacity is only around 250GB. |
| 00:59 | TrevorH1 | weirdly my ssd is quicker at writing than reading |
| 01:00 | dv_ | I think I have heard about such a phenomenon |
| 01:00 | TrevorH1 | ah, wait, bloody debian has /tmp on tmpfs ;) |
| 01:00 | MMlosh | I have a SD card by Kingston here.. it does >150MBps writing, but only 30MBps reading..... |
| 01:01 | MMlosh | don't forget that for small data quantities & using dd for measurements caches come into play |
| 01:01 | TrevorH1 | it's still quicker but not that much |
| 01:02 | TrevorH1 | dd if=/dev/zero of=/home/trevor/file bs=1M count=1024 oflag=direct --> 1073741824 bytes (1.1 GB) copied, 8.80006 s, 122 MB/s |
| 01:05 | TrevorH1 | using conv=fdatasync instead of oflag=direct gives a more expected result of ~75M/s |
| 02:40 | dv_ | \o/ vc-1 playback works now |
| 02:48 | Coburn | Makes me wonder if I should go back to CuBox dev |
| 02:48 | Coburn | I've been playing with R-Pis too much :P |
