Editing SATA (section)

=== SATA revision 1.0 (1.5&nbsp;Gbit/s, 150&nbsp;MB/s, Serial ATA-150) <span class="anchor" id="1.0"></span> ===
Revision 1.0a<ref name="SATA1a" /> was released on January 7, 2003. First-generation SATA interfaces, now known as SATA 1.5&nbsp;Gbit/s, communicate at a rate of 1.5&nbsp;Gbit/s, and do not support [[Native Command Queuing]] (NCQ). Taking [[8b/10b encoding]] overhead into account, they have an actual [[uncoded transfer rate]] of 1.2&nbsp;Gbit/s (150&nbsp;MB/s). The theoretical burst throughput of SATA 1.5&nbsp;Gbit/s is similar to that of [[Parallel ATA|PATA]]/133, but newer SATA devices offer enhancements such as NCQ, which improve performance in a multitasking environment.

During the initial period after SATA 1.5&nbsp;Gbit/s finalization, adapter and drive manufacturers used a "bridge chip" to convert existing PATA designs for use with the SATA interface. Bridged drives have a SATA connector, may include either or both kinds of power connectors, and, in general, perform identically to their native-SATA equivalents.<ref>

{{As of|2010|4}}, the fastest 10,000&nbsp;rpm SATA [[hard disk drive]]s could transfer data at maximum (not average) rates of up to 157&nbsp;MB/s,<ref name="Tom2010HardDrives">{{Cite news|title=VelociRaptor Returns: 6Gbit/s, 600GB, And 10,000 RPM  |website=tomshardware.com |author=Patrick Schmid and Achim Roos |url=http://www.tomshardware.com/reviews/wd6000hlhx-velociraptor-600gb,2600-5.html |date=2010-04-06 |access-date=2010-06-26}}</ref> which is beyond the capabilities of the older PATA/133 specification and also exceeds the capabilities of SATA 1.5&nbsp;Gbit/s.
