Technické parametry

Transcend TS256MDOM40V je flash modul 256MB s 40-pinovym IDE rozhranim, nahrada pevneho disku. Modul se zasouva primo do konektoru na zakladni desce. Na horni strane je maly prepinac MASTER/SLAVE a miniaturni konektor pro napajeni 5V DC. Soucasti dodavky je napajeci kablik s konektorem jako bezny IDE disk (12V, 5V). Nektere zakladni desky snad mohou modul napajet primo (napajeni na pinu20). Minimalni pocet zapisu je cca 100000. Nepodporuje S.M.A.R.T. Nepodporuje DMA rezimy, jen PIO0-PIO4. Rozmery 62x27x7.

 setting 32-bit IO_support flag to 1
 IO_support   =  1 (32-bit)

 Timing buffered disk reads:   16 MB in  3.05 seconds =   5.25 MB/sec

# hdparm -c3 /dev/hda; hdparm -tT /dev/hda
 setting 32-bit IO_support flag to 3
 IO_support   =  3 (32-bit w/sync)

Postup zprovoznění pod Linuxem

Jako bezny pevny disk. Vzhledem k pouziti flash technologii je treba pamatovat na omezeny pocet zapisu (minimalne 100000).
