BIOS bug
You did not see the BIOS password bug because Intel stopped distribution of these drives when they found the bug, and only sent the drives back out after they had their firmware updated.
Intel was the first company to deliver a Sata SSD, its 80GB X25-M, and we were blown away by the combination of speed and silence. Unfortunately, the price was rather steep but you can’t make an omelette without breaking eggs. When we reviewed the X25-M, it never occurred to us to ask about the fabrication process that Intel …
... ordered a week ago, still waiting. Not in stock!
And I agree, one of the most important figures for system disk is random small write. Old HD-tach charts (continuous read and write) are almost irrelevant for SSD 1. technology is fast enough most of the time anyway 2. they do not catch "stuttering" problem.
4k Random IO is the most important IO you do on most machines.
The MAXIMUM, not average latency of these operations is critical - remember the original non intel drives? Really fast, then stalled for a second, then really fast...
That seriously illustrated that the relevant benchmarks are not throughput for almost anyone...
