I/O Performance, Access Time
Let’s look at the juicy benchmarks now:
As expected, the I/O performance of Intel’s X25-E is amazing, beating all of the competition. Using our database benchmark pattern—which reads and writes small chunks of data—the X25-E delivers at least 5,000 I/O operations per second, dropping to around 3,000 I/Os per second at deep command queues. Obviously, the controller and its caching mechanism do not introduce an advantage in this scenario. However, the X25-E is still at least four times faster than the second-best SLC flash SSD, the Memoright MR25.2-064S. We also found it interesting that the X25-M also did rather well. However, the results with large command queues show that the MLC flash memory clearly isn’t as fast.
The file server performance results are similarly impressive.
Think of an HTML document, which consists of text and several images, and you’ll understand what Web server I/O requests look like. Most flash drives do well in this benchmark, as they are quick at random reads. Mtron’s Pro 7500 obviously was optimized for random reads, as it is the best in this benchmark. Intel’s products are second and the others follow close behind, delivering 10X better I/O performance than our two 15,000 RPM hard drives.
The workstation benchmark pattern utilizes 64, 128 and 256 KB block sizes, with 80% reads and 80% random access. The X25-E takes off again here, leaving every other drive in its dust.

So just how long till desktop enthusiasts see "reasonable" (~$150) prices for these drives?
2 years ago when the SSD hype started, they said "2 years" until this hits the mainstream market. People back then thought flash memory would be faster, have quicker access times, energy efficient, big and CHEAP. SSDs until the X25 series turned out to be neither. And with less than 10ct/GB HDD will no be beaten that quickly.
I'd say, 2 year until this hits the mainstream market. ;-)
can somebody please explain the difference between the poor file server performance of the x-25M compared to the rather good performance on the webserver. Is it to do with the size of the files being read or doing reads and writes at the same time? Considering that most production enviroments for web and file servers consist of about 90% reads and 10% writes on average, do the benchmarks above reflect this?
If I could justify the cost I would shoehorn two of these baby's into my laptop immediately!
I would love to see what four of these in a striped and mirrored RAID array could do...
Although this comparison of Intels X25 was nice to see against cheeter HD 15,000rmp drives & the Samsung,
Can someone please tell me why Toms hardware are still avoiding putting the Intel X25 up against the OCZ Vertex & OCZ Apex series in these bench mark tests ?, or are they afraid that the new OCZs SSDs might beat the X25 !.
Again this is just another fixed bench test to me where the Intel as been matched up against some no hope contenders.
Maybe this test was done by the boxing promoter DON KING, < he was a dodgy fixer of matchers.
Unicomplex, its probably because the OCZ drives are a load of toss
has OCZ got their bottlenecking issues sorted out yet ? or are they still relying on the people on their forum to provide workarounds such as formatting in 4kb chucks/stripes and formatting allignment to overcome piss poor component selection ? Intel has proved, good quality components can make or break a drive, sure you pay through the nose.... but you also dont end up with a lot of pissed off customers, OCZ's customer service on $500+ units is dreadful
