Everything else being the same, how much faster is SATA-150 than an average IDE?

Question

and is SATA-300 twice as fast as SATA-150?

Answer 1

IDE transfer rate is 133 and theoretically SATA II 300 should be twice as fast but all things are rarely equal in the IT world so no although it is faster it's not twice as fast ... the big advantage is larger cache and NCQ as standard

Answer 2

nicely, even the first technology of SATA drives should be in a position to handle 150MB in line with second and the utmost throughput of an IDE rigidity is 127MB in line with second, so SATA might want to continually be swifter. yet you're quite perfect to anticipate that fragmentation will play an element. maximum benchmarking courses move information on an off the rigidity with a view to attempt the speed. If the rigidity is fragmented, those information may should be split in the approach the disk into countless elements, including extra search for time to the operation. even with the undeniable fact that, an quite previous first technology SATA rigidity may be utilizing a 'bridge chip' which lacks the countless useful elements recent interior the finest SATA specification that could slow the rigidity. the finest overall performance of the rigidity is ruled by how the OS handles it. The NCQ function interior the hot SATA drives is designed to allow the rigidity to operate extra perfect in multi-tasking situations. So I reckon some thing's up. you need to favor to be getting swifter speeds than you're. i'd defrag the disk and attempt back. If accessible empty it earlier use.

Ok- for one the cables are completely different - u cannot use and IDE cable or IDE connection on motherboard to connect a SATA Hard Drive.
.
Yes SATA Hard drives are faster and therefore assist in data transfer rate a lot quicker.
This also depends on CPU speed and RAM
No SATA 150 / SATA 300 are only the the size of the hard drive - (150 Gigabyte and 300 Gigabyte)
No faster.
.
Remember to instal a SATA hard drive you would need a up-to-date mothreboard.
.
If your motherboard has both SATA and IDE connections, would advise NOT to use IDE and SATA hard drives together.
