Sorry, maybe I have missed some line or misunderstood the 'review' for the G3 but seems like the performance is not better than current crop of sanforce ssd (up to 270mb/sec write speed) Good if some senior can help explain... thanks!
the strength of the intel ssds is not in the read or write speed.. it has one of the best random access speed... which still beats the sandforce currently from what i understand..
[The Intel drives are of course architected for the type of performance needed on a desktop/notebook and thus they deliver very high random write performance.
Random write performance is merely one corner of the performance world. A drive needs good sequential read, sequential write, random read and random write performance. The fatal mistake is that most vendors ignore random write performance and simply try to post the best sequential read/write speeds; doing so simply produces a drive that's undesirable.]

Research the SSD's Performance
SSDs are all about performance. This performance is typically specified by how well the SSD can access its data randomly or sequentially. Because certain data is inherently sequential (photos, music, and movies) and other data types are inherently random (applications, system log files, and OS files), there are different specifications for accessing each type of data. The random data read and write access performance is typically specified in IOPS (input/output operations per second). You should look for an SSD that has high IOPS for random data access performance - this will ensure that you have fast application launch times, faster user file access, and faster systems boots. Such advantages greatly enhance the user experience and limit how often you'll see the dreaded "hourglass". So what's a "good" IOPS rating for random read performance? You should aim for a drive that can randomly read 4 Kbytes of data at a rate of up to 35,000 IOPS. Think about an SSD reading data in 4Kbyte chunks -- the same way a cargo ship carries a specified payload back and forth between destination ports. A good random write specification is in the range of 6,500 to 9,000 IOPS at a minimum.
The sequential data read and write access performance is typically specified in MB/s (megabytes per second), which is a fitting way to measure sequential streams of data (as opposed to a random stream). Sequential read and write performance typically has less of a noticeable effect on performance. Sequential data access is limited by bus interfaces, protocols, devices such as USB 2.0, MPEG video and audio, and DVD optical devices. Such interfaces are limited by throughput capabilities and protocol specifications, so exceeding the sequential platform requirement does not necessarily enhance the user experience. So what kind of sequential performance should you look for when buying an SSD? A good sequential read performance is 250 MB/s. A 70MB/s to 100MB/s sequential write performance is adequate for most uses.
