SATA Interface Data Transfer Rate
Since its introduction in 2001, the SATA interface has undergone three major revisions. The primary difference between the versions lies in the data transfer rate.
| SATA Interface | Interface Gb/s | Bandwidth Throughput | Compatibility |
|---|---|---|---|
| SATA I | 1.5Gb/s | 150MB/s | – |
| SATA II | 3Gb/s | 300MB/s | Compatible on SATA I ports |
| SATA III | 6Gb/s | 600MB/s | Compatible on SATA II and SATA I ports |
Other SATA-based interfaces
The other primary SATA-based interfaces are mSATA (mini SATA), M.2 SATA, SATA Express, SATA, and Micro SATA.
1, mSATA
The mSATA interface is also known as mini-SATA. It was developed for portable devices in the early days to accommodate ultra-thin devices, such as Ultrabooks, better. It can be regarded as a mini version of the standard SATA interface, and the physical interface (interface type) is the same as the mini PCI-E interface.
2, M.2 SATA
The M.2 interface is a new specification introduced by Intel as an alternative to mSATA, which is also known as NGFF, or Next Generation Form Factor.
M.2 interface SSD width is 22mm, with a single-sided thickness of 2.75mm. The double-sided flash layout is only 3.85mm thick. However, M.2 offers a wealth of scalability, with the longest possible length reaching 110mm, allowing for increased SSD capacity. m.2 SSD and mSATA are similar; they do not have a metal casing. Standard specifications are 2242, 2260, and 2280, with a width of 22mm. There are three types of SSDs, all with a width of 22mm and varying lengths.
3, SATA Express
SATA Express is part of the SATA 3.2 standard. It is not an entirely new command or protocol, but rather a specification that combines SATA and PCI Express signals within a single interface. Thus, it is fully compatible with existing SATA devices and cables. The only difference is that it allows for the connection of PCI-E SSDs.
4, eSATA
eSATA is an extended SATA interface that connects external devices rather than internal ones. The eSATA interface is based on standard SATA cables and interfaces, with metal shrapnel added to the connections to ensure a solid physical connection.
5, Micro SATA
The Micro SATA connector (sometimes referred to as uSATA or μSATA) originated with SATA 2.6 and is a combined SATA data and power connector for a 1.8-inch SATA solid-state drive (SSD) or hard disk drive (HDD).
Frequently Asked Questions (FAQs)
Q1: What types of SATA cables do you offer?
We provide custom SATA data and power cables, including standard SATA, eSATA, SATA III (6 Gbps), and combo cables (data + power). Options include straight, right-angle, and 7+15 pin connectors.
Q2: Can I customize SATA cable length and color?
Yes. We support full customization of cable length, jacket color, labeling, and connector orientation to suit your specific application or branding needs.
Q3: Are your SATA cables compliant with SATA III specifications?
Absolutely. Our cables are designed to meet or exceed SATA III standards (6 Gbps), with optimized impedance and shielding to ensure high-speed, error-free data transmission.
Q4: Do you offer locking latch connectors for SATA cables?
Yes. We provide SATA connectors with locking latches to ensure secure connections, especially useful in high-vibration environments like industrial PCs or embedded systems.
Q5: Can you produce SATA to other interface cables, like SATA to USB or MOLEX?
Definitely. We can manufacture hybrid assemblies such as SATA to USB, SATA to MOLEX, or SATA to Micro SATA, tailored to your exact connectivity needs.
