Let’s replace the old hard disk in my vintage IBM ThinkPad X40 with a modern SSD using an IDE-mSATA adapter. Seeing is believing, so check out the video which will give you all details and results.
The old 1.8 inch mini hard disk is very slow and noisy but still working. Main problem is the old IDE controller and the tiny form factor so we need an adapter to mSATA which I got from eBay in China for 3€ or 7€ each. Note that there are two version available: 3.3V (X40/41) and 5V (T40-T43, T23 and probably for all 2.5″ IDE disk drives).
The adapters are powered by a well known JMicron JM20330 converter. I had no problems with it and everything worked fine including TRIM under Windows 7.
We are using the lowest cost SSD on the market right now directly from eBay China: the Vaseky V800. We have the 64 GB model for less than 20€. It seems to be using SanDisk components similar to a SanDisk Plus model.
We did install Windows 7 on it with updates and some programs and ran some benchmarks. You can check out the video for detailed instructions and benchmarks. Spoiler: the SSD/adapter combo seems to work just fine and did increase speed to a very notable extend and reduced noise to pure silence. Of course long term quality is unknown but it is probably more reliable than the old hard disk.
