Bookmark or Share- Max read/write speed of a SATA 3.0 HDD rated at 6.0Gb/s?So what is the maximum read/write speed of a SATA III HDD at 7200 rpm with SATA 6.0gb/s interface? I ask this question because I plan to buy Seagate Exos 7E8 4TB 512n SATA 128MB Cache 3.5-Inch Enterprise Hard Drive (ST4000NM0035), it has 128MB cache instead of mine's 64MB, so what read/write speed should I expect? Would it be about 256MiB/s ...
- Will any SATA hard drive work with any SATA motherboard?So it doesn't matter whether it is a SATA 1 controller with a SATA 3 drive or a SATA 3 controller with a SATA 1 drive, or any combination with SATA 2 as well, they should all work together just fine. The only exception in my experience is that some older SATA drives require a 3.3 volt supply, while most drives work fine without it.
- Can hard drives fully utilize SATA III? - Super UserA drive with a maximum data transfer rate of 301 MB/s doesn't max out SATA III's 600 MB/s, but it will be limited by SATA II's 300 MB/s. A drive's throughput (disk-to-computer transfer rate) is affected by both the internal (disk-to-buffer) and external (buffer-to-computer) transfer rate.
- Sata III to Sata II Port - Super UserSATA III devices are backwards-compatible with SATA II. You can plug any SATA III device into a SATA II port. Note that you will experience a reduction in (theoretical) performance, as SATA II is an older, slower standard (3 Gb/s as opposed to SATA III's 6 Gb/s).
- How can I determine the SATA controller version on Windows?This is the situation on my laptop, where I have an old 2.5-inch 320 GB hard drive installed, which has SATA II (3 Gbs/300 MBs); but the software (when you look under the right section) shows that the disk controller for the computer supports SATA III (6 Gbs/600 MBs).
