Corsair P64-RAID-PK1 SSD Review
Enthusiasts are no stranger to RAID arrays. While server administrators depend on the redundancy of RAID-1 and other safe multi-drive configurations, performance enthusiasts are willing to risk it all for the promise of twice the normal performance from a striped RAID-0 array. To enjoy the added speed there must be two identical drives to which the data can split and write to each drive in stripes. Solid State Drive products already come at a premium over their hard drive counterparts, and most enthusiasts save up for just one SSD to help launch their computer system into hyper-speed. In this article, Benchmark Reviews tests two 64GB Samsung-based Corsair P64 CMFSSD-64GBG2D MLC Solid State Drives configured in a RAID-0 array for top performance.
Anyone familiar with articles published at Benchmark Reviews is very well aware of our obsession with Solid State Drive technology. They're complex, and every SSD is different than the next. Nothing like Hard Disk Drive technology, which improves as spindle speed and cache buffer are increased, SSDs are the future and because of this their internal architecture is constantly evolving. This is why we offer so much coverage on the topic: it's interesting and exciting. Plus, they can turn the average computer system into a roaring beast. It's not marketing hype; for once the truth is stranger than fiction.
Since first making a public debut at the 2007 Consumer Electronics Show, Solid State Drives (SSDs) have been a topic of hot discussion among performance enthusiasts. These nonvolatile flash memory-based drives feature virtually no access time delay and promise a more reliable storage medium with greater performance while operating at a fraction of the power level. Moving into 2008, SSDs became a consumer reality for many performance-minded power users. Now that 2009 has proven how strong the industry support behind Solid State Drive technology is, we should hope that mainstream acceptance moves faster than it did for DDR3 SDRAM.
Solid State Drive products are no longer restricted to bleeding edge hardware enthusiasts or wealthy elitists. Heading into 2009, SSD storage devices were available online for nearly $2 per gigabyte of storage capacity while the most popular performance desktop hard drive hovered just above $1/GB. While most consumers are waiting for that day when SSD costs the same as HDD, they seem to be forgetting how Solid State Drives have already surpassed Hard Disk performance in every other regard. Our collection of SSD reviews is a good starting point for comparing the competition.
EDITOR'S NOTE: As of 21 January 2010 Corsair Offers Firmware with TRIM Support for P-Series SSDs.
SSD Testing Disclaimer
Early on in our SSD coverage, Benchmark Reviews published an article which detailed Solid State Drive Benchmark Performance Testing. The research and discussion that went into producing that article changed the way we now test SSD products. Our previous perceptions of this technology were lost on one particular difference: the wear leveling algorithm that makes data a moving target. Without conclusive linear bandwidth testing or some other method of total-capacity testing, our previous performance results were rough estimates at best.
Our test results were obtained after each SSD had been prepared using DISKPART or Sanitary Erase tools. As a word of caution, applications such as these offer immediate but temporary restoration of original 'pristine' performance levels. In our tests, we discovered that the maximum performance results (charted) would decay as subsequent tests were performed. SSDs attached to TRIM enabled Operating Systems will benefit from continuously refreshed performance, whereas older O/S's will require a garbage collection (GC) tool to avoid 'dirty NAND' performance degradation.
