FOXSAT HDR - Disk upgreade - Advanced Format
Someone on AV has installed a WD10EURS with advanced Format without problems - I have asked him to let us know if any arise - but currently all looking good.

Not quite off-topic (as the subject is HDD upgrades) The Wall Street Journal reported yesterday that Samsung are selling their HDD division to Seagate.

It would be interesting to see what the partition starts & sizes are. The Advanced Format disks use 4k byte sectors instead of 512 byte sectors, so for best performance, the partition starts should be on 4k boundaries with size a multiple of 4k. Also the OS should do reads/writes as multiples of 4k (Linux will do that so the HDR is probably OK). I believe the drives will work in a 512 byte environment, but with reduced performance.
Reading up, allowing the drive to convert from 512 to 4k, the performance hit could be dramatic; and as I then found someone selling the EVDS at a bargain price (just pence more than the EURS) it then became a 'no brainer' to go the well-tested route. I'm still interested to know how the AF drives perform in the Foxsat though! |

I was considering the EURS as an upgrade but was concerned that the cut-down Linux on the Foxsat-HDR might be a pre-AF drive compatibility version, so unable to natively handle the 4k sectors.

Just realised - WD10EVVS only has a 8Mb cache - hope that's good enough for 2 HD recordings and a HD playback at the same time! |
