原來筆者一直對SATA介面有著錯誤的理解，
筆者看有很多人跟筆者一樣吧。
先看看這份來自SATA-IO的表格：
| SATA-IO Specifications & Naming Conventions | |||
| Specification Revision | Technology Generation | Data Transfer Rate | Interface Name |
| SATA Revision 3.x (Not 'SATA III') | Third generation not 'Gen 3' | Up to 6Gb/s | SATA 6Gb/s + [product name] |
| SATA Revision 2.x (Not 'SATA II') | Second generation not 'Gen 2' | Up to 3Gb/s | SATA 3Gb/s + [product name] |
| SATA Revision 1.x (Not 'SATA 1') | First generation not 'Gen 1' | Up to 1.5Gb/s | SATA 1.5Gb/s + [product name] |
Important: Do not use the incorrect terms 'SATA II' or 'SATA III' The references embedded within the SATA specifications to 'Gen 3', 'Gen 2', or 'Gen 1' are technical spec naming conventions only and should not be used for marketing and product naming purposes. | |||
| Mechanisms/Devices | Terms to Avoid | Interface Speed Options | Additional Capabilities |
| Cable Connections Disk Drives Host Devices Port Multiplier Devices Port Selector Devices | SATA III SATA 3.0 | 1.5Gb/s, 3Gb/s, 6Gb/s (Note: SATA 6Gb/s is backward compatible with SATA 3Gb/s, and SATA 3Gb/s is backward compatible with SATA 1.5Gb/s) | Asynchronous Notification ClickConnect eSATA HotPlug Link Power Management Native Command Queuing (NCQ) Staggered Spin-Up xSATA |
Results in the following examples of product marketing names... | |||
| Device name + | SATA Speed + | Additional Capabilities | |
| ACME Disk Drive | SATA 6Gb/s or SATA 3Gb/s | NCQ, Hot Plug, Staggered Spin-Up | |
| ACME Port Multiplier | SATA 6Gb/s or SATA 3Gb/s | NCQ, Staggered Spin-Up | |
| ACME Port Selector | SATA 1.5 Gb/s | eSATA, NCQ | |
| ACME Cable | Up to 6Gb/s | std, eSATA, xSATA | |
| ACME Connectors | Up to 6Gb/s | std, eSATA, xSATA | |
Important: Do not use the incorrect terms 'SATA II' or 'SATA III' The references embedded within the SATA specifications to 'Gen 3', 'Gen 2', or 'Gen 1' are technical spec naming conventions only and should not be used for marketing and product naming purposes. | |||
看了這表格後大家也會嚇一跳吧，
原來掛在口邊多時的SATA II並不是介面的名稱。
有趣的是：有很多商店及廠商也犯了同樣錯誤。
難怪SATA-IO要提出書面的澄清了
