SATATerminology

Parallel ATA (PATA)

  • Parallel bus architecture

  • Also known as ATA

Serial ATA (SATA)

  • Serial bus architecture

SATA II

Is name of the organization that authored the second generation SATA specifications.

That organization is now called the Serial ATA International Organization (SATA-IO)

For more information, read the naming guideline spec:

Frequency and Quality

  • high frequency and high quality

  • backwards compatible with 1st Generation

All TCC SATA and SAS assemblies are

TCC uses the latest engineering and manufacturing techniques to provide improved cable signal integrity through impedance matching and reduced crosstalk.


Sata cable properties22 l.jpg

SATACableProperties

High Frequency and High Quality Cable

The following information about frequency and quality is given to understand the basic:

  • characteristics of the cable used in assemblies

  • cable’s affect on performance


Sata cable properties23 l.jpg

SATACableProperties

High Frequency and High Quality Cable:

Frequency and speed are the same when discussing data transmission in these SATA 3Gbs cables.

Frequency

  • High Frequency cables meet the SATA standard 3Gbs for data transmission.

  • Low Frequency cables do not and are generally poor quality cables.


Sata cable properties24 l.jpg

SATACableProperties

High Frequency and High Quality Cable

High Frequency Cables

  • transmit signals down the cable at a high rate of speed.

  • run at 1.5 and 3.0 Gbs

  • meet SATA specifications


Sata cable properties25 l.jpg

SATACableProperties

High Frequency and High Quality Cable:

Low Frequency Cables

  • The signals are transmitted down the cable at a low rate of speed.

They are usually:

  • low quality cables

  • out of 3Gbs specification


Sata cable properties26 l.jpg

SATACableProperties

High Frequency and High Quality Cable:

Low Frequency Cables

  • Low performance usually because of poor quality:

  • - inadequate soldering joints

  • -careless cable preparation

  • - inferior cable and cable assembly manufacturing methods.


Sata cable properties27 l.jpg

SATACableProperties

High Frequency and High Quality Cable

High Quality Cables

Cables must be manufactured by reputable suppliers to ensure:

  • assembly quality

  • electrical quality

  • cables were not manufactured on the bench top


Sata cable properties28 l.jpg

SATACableProperties

High Frequency and High Quality Cable:

High Quality Cables

  • support high bandwidth differential signaling

figure 1

  • use twin-ax wiring in a coax-type transmission cable (figure 1)

Internal Cables: Single-lane and multi-lane

External Cables: Multi-lane

SHIELDING & DRAIN WIRES

figure 1

The method of shielding the cable has a profound effect on the cable’s performance and is a major factor in quality and cost (figure 1).


Sata cable properties30 l.jpg

SATACableProperties

High Frequency and High Quality Cable

High Quality Cables

Proper Shielding Methods

  • Each channel hastwo conductors, both jacketed by a primary insulator.

  • The pair of conductors is covered completely by a conductive shield, either foil or braided.

  • Precision-wound, spiral wrap foil shielding and drain wires guarantee continuity of the shield.

  • The entire assembly is covered with (usually PVC) an insulating and protective outer layer called the jacket.


Sata cable properties31 l.jpg

SATACableProperties

High Frequency and High Quality Cable

High Quality Cables:

Inadequate shielding causes:

  • Impedance Discontinuities: unraveled shields or broken shield connections will cause reflected signal energy.

  • Cross-Talk, Signal Loss, EMI (electromagnetic interference): will be caused by discontinuous shielding.

  • Excessive Conductor Skew: faulty connector terminationalso causes the above performance hindrances.

SATACable Properties

High Frequency and High Quality Cable

Remember:

High Frequency cables meet the SATA standard for data transmission.

Low Frequency cables do not and are generally poor quality cables.


Sata assembly properties l.jpg

SATAAssemblyProperties

SATA 3Gbs Cables

  • Thin, flexible, coax-like cable

  • SATA connector types:

    • Straight or right-angle

    • Click-connect (latch) or friction-fit attachment

    • Low profile or large

  • SAS connectors can be on SATA cables (fanouts)

eSATA Cables

eSATA

  • Not a SATA “L” connector interface

  • For portable external drives

  • 6X faster than USB 2 and 1394

  • Single lane transfer

  • Guide keys on both sides of connector face

  • Secured by latch on top of connector face

  • Designed for 5K insertions & removals

    • Regular SATA only 50 Insertion & Removal Cycles


Sata assembly properties36 l.jpg

SATAAssemblyProperties

External SATA Cables

  • Same “L” Interface as internal SATA

  • Different Interface than eSATA

    • Key on one side only

    • No securing latch- uses friction method

Sata and sas l.jpg

SATAandSAS

Similarities

  • Both SATA and SAS connectors can be on the same cable assembly.

  • Both types of HDD drives plug into the SAS backplane.

  • Both types of drives are interchangeable within a SAS drive bay module.

  • Both are long-proven technologies with worldwide acceptance.


Sata and sas39 l.jpg

SATAandSAS

Differences

  • SATA backplane cannot accept SAS drives.

  • SAS backplane can accept SATA drives.

  • SATA drives are less expensive than SAS.

  • SAS drives have:

    • Dual porting capability, faster spindle speeds, & lower latencies.


Sata and sas40 l.jpg

SATAandSAS

Differences

  • SAS drives undergo more rigid testing specifications than SATA.

  • SAS drives have longer MTBF and duty cycle than SATA.

  • SAS drives are faster and offer more features than SATA:

    • Variable sector sizes, LED indicators, dual ports, & more stable data integrity

SAS & SATA Connector Details

SAS has same footprint as SATA (7 + 15 pins) except it has 2nd physical layer


Sata and sas42 l.jpg

SATA and SAS

What to choose

  • SATA when COST is #1 priority

  • SAS when PERFORMANCE is #1 priority

  • SATA has simplest set-up

  • SAS has greater scalability

  • SATA has better power management

  • SAS has greater device flexibility
