/dev/hdb:
 Timing cached reads:   1004 MB in  2.01 seconds = 499.20 MB/sec
 Timing buffered disk reads:   40 MB in  3.09 seconds =  12.96 MB/sec

suppongo che questi due parametri dipendano dal fatto che e' un disco
ata, mentre il tuo dovrebbe essere un sata (o no ?)
Sono valori apprezzabili o no ?
Ciao, e grazie
