<strong>KC100</strong> & <strong>HyperX</strong> <strong>SSD</strong><br />
Benefits of Synchronous versus Asynchronous NAND<br />
Introduction<br />
The purpose of this paper is to analyze the performance impact of using synchronous NAND, as found in the <strong>Kingston</strong><br />
<strong>KC100</strong> and <strong>HyperX</strong> <strong>SSD</strong>, versus asychronous NAND, found in the competitive <strong>SSD</strong>’s featuring SATA 6Gb/s and a SandForce<br />
SF-2281 controller.<br />
Our Test System<br />
<strong>SSD</strong>’s Compared:<br />
<strong>Kingston</strong> <strong>HyperX</strong> <strong>SSD</strong> 120GB SATA 6Gb/s featuring SandForce SF-2281 Controller and synchronous NAND (same<br />
components as <strong>KC100</strong>)<br />
Competitor A: 120GB SATA 6Gb/s <strong>SSD</strong> featuring SandForce SF-2281 Controller and asynchronous NAND<br />
System Used:<br />
Gigabyte Z68 Motherboard<br />
4GB of KVR 1333 DRAM<br />
Intel 2500k CPU<br />
EVGA GTX 550 Video Card<br />
Windows 7 64 bit with latest drivers and Intel RST 10.6 installed<br />

Benefits of Synchronous versus Asynchronous NAND<br />
Sequential Read/Write Speeds using ATTO 2.41<br />
Comments:<br />
<strong>KC100</strong>/<strong>HyperX</strong> Peak Performance:<br />
Peak Reads: 559MB/s<br />
Peak Writes: 491MB/s<br />
(higher is better)<br />
Competitor A:<br />
Peak Reads: 550MB/s<br />
Peak Writes: 482MB/s<br />
(higher is better)<br />
The <strong>KC100</strong> and <strong>HyperX</strong> <strong>SSD</strong> using synchronous NAND are marginally faster than the competition’s asynchronous NAND.<br />

Windows 7 Boot Times<br />
Comments:<br />
<strong>KC100</strong> and <strong>HyperX</strong> <strong>SSD</strong> are still a bit quicker booting Windows 7 on our test system.<br />
Note: No boot optimizations were utilized in this test. BIOS was left in default mode.<br />

Comments:<br />
Performance difference in NAND is really apparent here. Specific to write performance the synchronous <strong>Kingston</strong> <strong>SSD</strong><br />
outscored the competition by 59% in random write performance and 27% random read.<br />

Benefits of Synchronous versus Asynchronous NAND<br />
PCMark Vantage Suite<br />
Comments:<br />
Advantage<br />
Synchronous<br />
Starting with the PCMark Overall system score, the synchronous NAND improved system performance by almost 10%.<br />
This increase is significant because these performance increases are noticeable to the end user as they perform these<br />
categorical tasks.<br />
Across nearly all tests, synchronous NAND outperforms the slower asynchronous NAND by an impressive 22% in the<br />
productivity suite and also by 58% in the Vantage HDD Suite which is a pure measure of drive performance.<br />

PCMark Vantage – HDD Suite Individual Tests in MB/s<br />
Comments:<br />
Advantage<br />
Synchronous<br />
During the various HDD specific tests run during PCMark Vantage Suite, the <strong>KC100</strong> and <strong>HyperX</strong> <strong>SSD</strong> significantly<br />
outperforms the asynchronous-based <strong>SSD</strong> in transfer rates measured in MB/s.<br />

Benefits of Synchronous versus Asynchronous NAND<br />
Conclusion<br />
• In comparison to asynchronous NAND, the synchronous NAND used in <strong>Kingston</strong>’s <strong>KC100</strong> and <strong>HyperX</strong> <strong>SSD</strong> is<br />
noticeably faster across all benchmarks <strong>Kingston</strong> tested:<br />
o 10% increase in system performance (PCMark Vantage Suite)<br />
o 22% increase in productivity suite tests. (PCMark Vantage Suite)<br />
o 58% increase in pure drive performance (PCMark Vantage HDD Suite).<br />
• Asynchronous NAND is lower quality, lower in performance, and thus less expensive.<br />
• Asynchronous NAND is generally found in mass market, consumer-facing drives.<br />
• Synchronous NAND, found in <strong>HyperX</strong> <strong>SSD</strong> and <strong>KC100</strong>, target high-end, enthusiast and business customers. True<br />
enthusiasts and IT professionals will demand, pay for, and appreciate the benefits of the high performance,<br />
synchronous NAND<br />
