Following a seven-match losing streak which included a group stage exit from the Rugby World Cup and the wooden spoon at the RBS 6 Nations, wins over Australia and Fiji have restored pride, but Andy Robinson's men are determined to return home with a 100% record.
Glasgow Warriors forward Ryder, who made his Scotland debut against Fiji, knows many of the Samoa side well and expects a brutal encounter in Apia on Saturday.
"The Samoan forwards are better known than the Fijian ones, a lot of them are playing in France or in the Aviva Premiership or are in and around the PRO12," Ryder said.
"They are all playing good rugby, so it is going to be a full on international. It is nothing less than that.
"I am friends with Census Johnston from my time at Saracens and obviously with David Lemi from Glasgow.
"You just have to look at the name on their team sheet to see the quality and the standard of rugby that these players are producing.
"I would imagine they are going to be a tough, physical pack."
Samoa have a formidable team available to them and have just been crowned Pacific Nations Cup champions after an unbeaten tournament in Japan that culminated with them edging past the hosts to clinch the cup.
The results contributed to Samoa being ranked one place higher than Scotland in this week's International Rugby Board rankings.
Ryder is hoping for a longer spell on the field this weekend, having won his maiden cap for a two-minute appearance.
The lock was called on to the field against Fiji shortly before the final whistle, and though he is delighted to have gained that cap, it is not enough to satisfy the ambition that saw the lock shift his family to Glasgow, where his father, Paul, was born, to throw in his lot with Scotland after starting his career in England.
"The two minutes I was on didn't really feel any different to anything else I have done but I think I would have to play a little bit longer to get the full flavour of international rugby," he said.
"I think I have barely scratched the surface really. The whole match day experience, the whole build-up to both the Australia and Fiji games has been great.
"I have really enjoyed being here, just the training sessions and the increased intensity there has been fantastic. I am enjoying the whole experience.
"It is a fulfilment of a dream, but I do not want to have just the one cap and go away. I want to be playing regularly, having an impact on games and having a fulfilled international career."
