Question about disk performance while playing 2013-04-08 20:14:25 My whole music collection is placed on WD30EZRX HDD - Western Digital Green Power Drive with 4k physical sectors, SATA 3 interface and 64 MB cache. I know that WD Green and all power saving oriented HDDs doesn't have good performance when compared with regular HDD series (like Blue series for Western Digital) but is it possible that they simply suck? My problem is that when I play music with foobar and simultanously copy from or copy to my "music" hard drive, playback is often interrupted. Animations like musical spectrum or spectrogram stutter all the time. When they start stuttering I hear no sound - there's silence while it happens. After few seconds animations start working properly for another several seonds and I hear the sound again. After that everything starts stuttering again. This happens for about 2-4 minutes. After that it seems that sound starts working correctly. Is it normal foobar behaviour on such hard drives? I know for sure that it happens when I copy large files (like 10, 80, 120 GB), I'm not sure whether it hapens for much smaller files like mp3s. Configuration details:WD30EZRX HDD is connected to Gigabyte's GA-890GPA-UD3H motherboard using SATA 3 cable (bundled with MB). Motherboard is based on AMD RS880D/SB850 chipset. I use latest drivers for that chipset (but it doesn't matter what version was used - it happened since the very beginning). HDD is working in AHCI mode and ESP is enabled for it (it can be hot plugged/unplugged). Foobar is using DirectSound output (using integrated Realtek HD Audio device) and it has 2500 ms buffer set. By the way - what is the default/recommended value for buffer? This setting was made years ago with different foobar version and for different hardware configuration. Other drives on my computer are all WD drives - WD1002FAEX for system and WD20EADS for other storage purposes. Does my hardware sucks so badly that it's normal?Thanks in advance for any suggestions.
