The main issue I've seen with replacing the drive as documented by various posts is that the SATA to PATA adapter makes the fitting of the new drive a little awkward. There has been reference to only being able to use 2 of the 4 mount screws, another reference that sawed the metal cage to make space. None of these are major showstoppers, but I was wondering what the less worrisome alternatives are before heading down the road.
1. Instead of replacing the drive with a 2.5" SATA SSD and use a 2.5 SATA to 3.5 PATA adapter, why not instead use a 2.5" PATA SSD and avoid the adapter altogether?
This is an example of a 2.5" model: http://www.amazon.com/128GB-KingSpec-2-5-inch-SM2236-Controller/dp/B0091T4ZWU (not suggesting this is a reliable brand but just referencing it as an example)
2. Use a 1.8" SATA SSD and use a 1.8" SATA to 3.5" PATA/IDE converter
Example of 1.8" SSD: http://www.amazon.com/Kingston-Digital-SSDNow-SKC380S3-120G/dp/B00DCUKKK0/ref=sr_1_4?s=pc&ie=UTF8&qid=1449158110&sr=1-4&refinements=p_n_feature_keywords_two_browse-bin%3A4929542011
Example of Adapter: http://www.amazon.com/1-8-Hard-Drive-Adapter-Converter/dp/B004CS4NRW
3. Use a 1.8" PATA/IDE SSD
These all seem to be cheaper alternatives too (though cost isn't my main driver - I'd rather have a drive that doesn't fail and won't upset the DKV)
Being a non-engineer I'm just going by the terms PATA and SATA and assuming 1 and 3 will fit into whatever socket the MKIV HD is using.
Many thanks,
