Beware of SSD HD, for speed there no differneces with 6Gb/s SATA

SATA 6Gb/s drives: 500-600MB/s


SSD 6Gb/s drives: 500-600MB/s


===============================


SATA 6Gb/s drives are expected to hit the market in the second quarter of 2009. According to SATA-IO, the technology is backwards compatible with previous versions of SATA, using the same cables and connectors. Since SATA drives make up nearly 100% of drives in use today, upgrading to SATA 6Gb/s as easy as buying and installing a new drive.


SATA 6Gb/s is coming just in time to pair up nicely with USB 3.0, a newer USB standard. USB 3.0 supports a maximum theoretical speed of 600 MB/s, matching perfectly with the newest generation SATA. While USB 3.0 might not realize its maximum throughout in the real world, you can’t help but imagine all the time you’ll save with an external drive enclosure that supports USB 3.0, and two or more SATA 6Gb/s drives to speed through those disk-clone backups.


While some new technologies introduce as many new problems as they fix, no one has looked back since the introduction of SATA technology. Now with SATA 6Gb/s and USB 3.0 on the horizon, you can bet that everyone is looking forward.

Intel® Solid-State Drive DC S3700 Series: Specification

This document describes the specifications and capabilities of the Intel® SSD DC S3700 Series.

The Intel SSD DC S3700 Series delivers leading performance and Quality of Service combined with world-class reliability and endurance for Serial Advanced Technology Attachment (SATA)-based computers in four capacities: 100 GB, 200 GB, 400 GB and 800 GB.

By combining 25nm Intel® NAND Flash Memory technology with SATA 6Gb/s interface support, the Intel SSD DC S3700 delivers sequential read speeds of up to 500 MB/s and sequential write speeds of up to 460 MB/s. Intel SSD DC S3700 Sseries delivers Quality of Service of 500 us for random 4KB reads and writes measured at a queue depth of 1.

The Intel SSD DC S3700 Series also includes High Endurance Technology (HET), which combines NAND silicon enhancements and SSD NAND management techniques to extend the write endurance of an SSD, leading to lifetime endurance levels of 10 drive writes per day for 5 years.

The industry-standard 2.5-inch form factor enables interchangeability with existing hard disk drives (HDDs) and native SATA HDD drop-in replacement with the enhanced performance, reliability, ruggedness, and power savings offered by an SSD.

Intel SSD DC S3700 offers these key features:
• High Endurance Technology (HET)
• High I/O and throughput performance
• Consistent I/O latency
• Enhanced power-loss data protection
