Does this grinder still perform at the same level with only a small amount of beans in the hopper? I generally only use 30-40 grams at a time.

Absolutely! I use it the same way, 30 grams at a time, I do not leave beans in the hopper, and you shouldn't if you want fresh beans. But, you have the option to leave them in, you'd just use the timer to have it stop at 30 grams. You'd have to play with it to get the timing right for stopping at 30 grams. It's much easier just to poor only what you need and grind it as you need it, not to mention keeping it fresh. Although the hopper does seal air tight and it's somewhat dark to keep light out, your better off storing them in an air tight container that doesn't let light in at all.I also like a coarser grind so I bumped the burr up one notch and use the highest setting, something I couldn't do on the other brand. It has a wide range of settings from fine to coarse. You will not be disappointed. Here's a great review if you haven't spotted it yet, https://www.youtube.com/watch?v=lROYjaGA4R0, on the Whole Latte Love youtube channel. Great source of information.Tip1: As mentioned in an earlier post, I put a cup under it to catch the grinds then dump them in my filter. You could slide the tray out and grind directly into the filter. Note: You'll notice some static at first, grinds floating up onto the control surface and sticking but this dissipated over time. Or it did once I started using a glass cup.Tip2: I push the grind button on and off for a second to clear out old grinds, dump the little bit that comes out (old grinds), then grind my 30 grams. This way you don't have the old that was still in the burr dumped in with your fresh grinds. This was a tip from a Seattle Coffee Gear video, another great youtube channel.Tip3: you only need a brush to clean it out from time to time, do NOT use rice like some people suggest on youtube. It's very easy to clean. Remove the hopper and top burr, brush debris loose, tip it upside down over your trashcan and tap the side, done!

Is this good for espresso

Yes, the grinder is able to get you down to that fine espresso range. It will accommodate all pressurized brewing systems. It will also accommodate most non-pressurized brewing systems as well. Hope this answered your questions. Thanks.

does this machine will work with rancilio siliva?

I think this machine would work very nicely with the Rancilio Silvia. It produces a very fine grind all the way up to a very corse grind. So not only would it be great for your espresso it will also grind for drip coffee and press coffee as well.
