I bought one of these to replace the HD in my Fujitsu P7120 laptop. Overall it is working reliably but with somewhat less performance benefits than I had hoped.
I used a third-party PATA to ZIF adapter to connect the drive into my laptop. Windows recognized it immediately, with no issues.
The time to load Windows (from when the BIOS first reads the disk until the login screen appears) has improved by about 20%.
Application startup also seems noticeably faster. Because of Windows caching, it's hard to be precise, but it seems like at least 20% faster for Adobe Illustrator and more for Word.
According to MTRON's specification for this drive, for small operations it should deliver up to 25000 sequential reads/sec, or 48000 sequential writes/sec, or 16000 random reads/sec, but only 60 (sixty) random writes/sec. The sequential read and write numbers are extremely good. Alas, the very poor random write numbers are typical for a flash SSD.
So the performance impact will depend greatly on the kind of disk I/O you are doing. The high read rates should benefit system boot and application launching. But the low random write rates will tend to slow down things like copying lots of small files. Unfortunately Windows also has a nasty tendency to do lots of small random disk writes for its own housekeeping purposes (logs, timestamps, etc), including during startup.
I had an initial BIOS glitch (I've put details in a comment below) but that was fixed by upgrading to newer MTRON firmware, which should now be present in all new drives.
The bottom line: The drive works reliably, and as far as I can tell it meets the promised performance. So I'll give it four stars. But at the same time, the overall performance benefit on my laptop has been rather less than I had hoped. Maybe the fault is with Windows rather than MTRON, but overall my laptop feels only slightly faster. Your mileage may vary, but you should probably expect incremental rather than radical change.
Update May 2009: I am now happily using this drive with the Windows 7 Release Candidate. Overall performance seems significantly better than under Vista. Some of that improvement may be due to the enhanced SSD support in Windows 7.

SSD is not implemented by simply assembling flash memories. The difference in SSD technology depends on the controller that controls the flash memories used for storage. Mtron SSD MOBI uses the proprietary Multi-Channel Parallel Array controller technology to achieve maximum read and write speeds of 100MB/s and 80MB/s, respectively, which is three times faster than conventional hard disks.The lowest speed determinant theory states that the element with the lowest speed determines the overall speed. The theory also applies to the computing environment. Even though there have been remarkable advances in CPU and memory performances, the system bottleneck problem caused by the hard disk could not be resolved. Balanced harmony among the components is very important for achieving improvement of the overall system performance, and Mtron SSD MOBI is the optimal solution for eliminating imbalance.Mtron SSD MOBI yields startling speeds in reading and processing data. It expedites the booting procedure and produces clearly higher performance than the hard disk for tasks that involve high-capacity files, professional graphics and multi-tasking.
