As you can see, none of the drives exceeds 200 MB/s with the SATA II interface; not even the Samsung 830 and OCZ Vertex 3 (SF-22XX), which pass 300 and 350 MB/s with the SATA III interface. Furthermore, consumer-level SSDs could be much faster than even SATA III: For example, the PCIe SSD OCZ RevoDrive 3 has a maximum reading speed of 975 MB/s.

2024年1月1日 · The 600MB per second is still a raw transfer number, but is the usable rate due to encoding on the SATA bus to achieve DC-balance and a minimum amount of signal activity. Every eight bits of data are expanded into 10 bits for transmission on the SATA cable.

2021年3月13日 · 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 …

2015年12月14日 · SATA 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).

2015年5月29日 · By design, all newer SATA standards are backwards compatible with older SATA standards and will fall back to the slower speed such that they will work. 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 ...

2012年4月13日 · Yes. There is no difference in the cables. They have not changed with SATA revisions. When the Serial ATA International Organization (SATA-IO) began design of the SATA Revision 3.0 specification, the designers wanted to double the interface data rate while enhancing support for multimedia applications − without introducing major changes that could adversely …

2022年7月3日 · If I understand you correctly the computer has a SATA interface and a SATA to M.2 converter was used to connect the oriignal 256 GB M.2 SSD. A M.2 NVMe SSD in the same converter won;t work. This is totally as expected. The M.2 slot can support a SATA M.2 SSD, a NVMe M.2 SSD or both. But your SATA interface in the computer ONLY provides SATA.

The SATA 3 interface is known as "SATA 6Gb/s", so the theoretical speed is 600MB/s, but the SATA 3.2 revision allows a solution using PCIe to speed up the interface up to ~2GB/s (16Gb/s). So, can I say that for products with interfaces related to the 3.2 revision the theoretical SATA 3 speed is 2GB/s?

2018年11月30日 · I tried using CrystalDiskInfo, HD Tune and AIDA64 to understand if my four SATA 3 drives have a SATA 2 or 3 connection, but these software seem to report the device type instead. The issue is that the drive connected at SATA0 (blue one supposed to be SATA 3) is an SSD and shows speeds up to 240MB/s Seq Read and 70MB/s Write in CrystalDiskMark.

2015年12月9日 · The SATA controller on the mobo definitely impacts the maximum speed of your SATA ports. If you can't find SATA speed or version (SATA2 is 3Gbps, SATA3 is 6Gbps) specs for your mobo and it's more than a few years old, there's a good chance that it …
