Both drives you mention use SATA 3Gbit/s, which is sometimes called SATA Revision 2 (or SATA-II). SATA 3GBit/s should be backwards compatible with earlier SATA 1.5GBit/s hardware, but most hard drives also have a jumper to force the drive to …

Feb 1, 2013 · "Second generation SATA interfaces run with a native transfer rate of 3.0 Gbit/s, and taking 8b/10b encoding into account, the maximum uncoded transfer rate is 2.4 Gbit/s (300 MB/s)." If you put that SSD on SATA II you should expect +/- 300MB/s.

Both SATA-II connectors are backwards compatible with SATA-I, so it's OK to use a SATA-I drive on a SATA-II board and vice versa. The primary difference is the speed of the connection - SATA-II operates at 3.0 Gbps, whereas SATA-I operates at half that, or 1.5 Gbps.

Dec 14, 2015 · 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).

A 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.

Sep 15, 2016 · SATA 1, aka SATA 1.5GB/sec SATA 2, aka SATA 3.0GB/sec SATA 3, aka SATA 6.0GB/sec In theory all devices are compatible. A SATA-2 drive on a SATA-1 controller should just work, albeit at a maximum transfer speed of about 130MB/sec. ( SATA-1 speed, and compensating for the overhead in the protocol and the encoding).

Here is a simple table which shows how the mixing of SATA II and SATA III devices at the same bus results: SATA 2 + SATA 3 = SATA 2. SATA 3 + SATA 2 = SATA 2. SATA 3 + SATA 3 = SATA 3. So does it have a sense to install SATA 3 SSD on SATA 2 notebook? A bit broad questions because it depends on circumstances.

May 29, 2015 · 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.

Wikipedia says many things about different naming conventions, the closest being, "SATA II 3.0 Gbit/s, which was colloquially referred to as "SATA 3G" [bps] or "SATA 300" [MB/s] since 1.5 Gbit/s SATA I and 1.5 Gbit/s SATA II were referred to as both "SATA 1.5G" [b/s] or "SATA 150" [MB/s]). Therefore, they will operate with negligible ...

I brought a SSD last week that supports SATA III. I wish to connect it to my PC but I have no idea whether my PC has SATA II or SATA III. I can provide any details or screenshots if needed. Motherboard: ASUS M5A78L-M/USB3 Chipset: AMD 780G Processor: AMD …
