My HP dv6000 laptop has WD1600BEVS (SATA-I, 160GB, 8MB Buffer, 150 Mbps) hard-dive. I need to upgrade the hard-drive and I am planning for a SATA-II hybrid hard-drive. I have two options -
- Seagate ST1000LM014 SSHD (1TB, 5400RPM, 64MB Cache, 6Gb/s, 8GB SSD)
- Seagate Momentus XT ST750LX003 SSHD (750 GB, 7200RPM, 32MB Cache,6Gb/s, 8GB SSD)
The former has has lower RPM but higher packing density. But the latter has more RPM but lower packing density. Theoretically, there shouldn't be much difference between the number of sectors covered by the R/W head per unit of time, and hence the amount of data read/written per unit of time (practically, I am not very sure). The former has more cache and is about $10 costlier than the latter (as on Amazon).
Which hard-drive should I go with in terms of performance?
