Buna Adrian,

Chiar si numai cu hdparm si rezultatele erau deja concludente ... dar  
daca tot ai amintit de citirea secventiala vs random ... mai jos  
rezultatele, arata ca performantele pe storage sunt modeste ...  
comparabile (doar putin mai bune) cu ale unui disk IDE ATA133:

Storage MSA1000 (10 x U320 SCSI, 15K rpm, 72.8GB):
# ./seeker /dev/mapper/MSARAID5-STORAGE
Results: 158 seeks/second, 6.32 ms random access time

Hdd IDE, ata133 (ST380215A)
# ./seeker /dev/hda
Results: 67 seeks/second, 14.84 ms random access time

# intel SSD 100GB (INTEL SSDSC2CT12)
./seeker /dev/sda
Results: 4561 seeks/second, 0.22 ms random access time

# soft raid1 intel ssd 100GB (INTEL SSDSC2CT12)
# ./seeker /dev/md6
Results: 3546 seeks/second, 0.28 ms random access time

Diferentele sunt astronomice!

Mersi,
Alx
