Test WD Harddisků

Níže uvádím pár testů k článku o harddisku. Testovacími programy byly DiskSpeed 4.4, DriveSpeed 1.2 a SysInfo 3.24.

Testované disky:
1. WD Caviar 212,6, MB rok výroby 1994 - tak tenhle disk našel ještě spolu s dalšíma pěti kámoš na popelnici. Tenhle jedinej byl kupodivu dobrej (alespoň zdánlivě), tak sem ho hned změřil na rychlost. PIO=3.
2. WD Caviar 1 GB, rok výroby 1996 - můj starej dobrej, malej, ale ještě pořád docela rychlej disk. PIO=4NF
3. WD Caviar 15 GB, rok výroby 1999 - můj novej vysokootáčkovej disk. 7200 ot/min. PIO=4NF

Testováno bylo tak, že z diskety byl zaveden systém i s ovladačem Fast ATA a disk byl 3x změřen. Výsledná cifra je průměr všech měření. Disky měly stejné podmínky (počet buferů, fast file system ...) Vše na Amize 1200 s turbokartou Blizzart PPC 603/160mHz+68040/25mHz+74 MB RAM+Fast ATA. Bez zavedeného setpatche.

No a tohle jsou výsledky
