S-ATA also calle serial ATA have following benefits:
- New Technology
- 150MB/s data transfer rate
- thin data wires, you have less clutter in your system as well your air flow inside the casing improves (front to back)
- Hot swapalble (means u can unplug the cables from a running hard drive), but his I dont thik is some advantage, as no body un-plus wires in a running system, speciallly as if the systems casing is closed.
- jumperless, your primary and secondary depends on on what connector u attached the drive.
- spindle rotations can range from 7200rpm to 15000.
- quiet, infact i found them dead silent as conpared to my IDE Maxtor 7200 RPM in previous machine.
Cons: I havent seen any, except that they are little expensive than IDE hard drives:
now Ultra ATA, also called P-ATA (or parrallel ATA), is the advanced form of P-ATA, with data throughput of max 133MB/s
- spindle rotations range from 5400 to max of 7200RPM (in desktop drives)
- Jumper settings allow u to nonimate master and slaves
- 1.5-2 inch thick data cables, difficult to bend at tight corners and blocks efficent air flow.
- cannot be HOT Swapped like S-ATA does, but again, hot swapping to me isnt some real good advantage.
- louder than S-ATA in some cases
and last, good point = cheaper
