The drop in performance of an SSD due to bit-rot has been established, and running SpinRite level 3 is one method of restoring the performance. But is it necessary to do this on 100% of the drive or just the slow portion. For example, ReadSpeed and the Spinrite Benchmark show that the first 25-30% of the drive is slower than the rest. Would running SpinRite level 3 on just the first part of the drive be sufficient? Does the SSD's allocation of sectors to any physical area of the drive have an impact?

DNS Benchmark v2 is Finished and Available! Guest:
That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.

BootAble – FreeDOS boot testing freeware
To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.
GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.
The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.
You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.
(You may permanently close this reminder with the 'X' in the upper right.)
Absolutely!!! The slowness of the first 25-30% of the drive, where the OS, Apps, and data are located, is due to mainly to "Read Fatigue", i.e. the repeated reading of the same locations. A Level 3 refresh of just that slow area is all that is needed.
There is absolutely NO point to doing a Level 3 on the fast (and likely not yet used) areas of the drive.
