Hello Ar!yaN,
if you are looking for a stable/fast RDP I can recommend you Giga-Rdp.in.
I myself have two RDPs on two different server from giga-rdp (NL and FR server).
The customer support is quick and friendly and will try to sort out any problems you might encounter as fast as possible.
But don't take my word for it, you can get a 2 day demo to check it out for yourself.
Then you can test uploading/downloading to/from whatever host you want (rg, ul, etc.)
The best part is they have currently a
50% off deal, where you can get a
500gb rdp
@1GiBit Port for only $16.40 USD instead of the usual $32.80 USD.
If you don't need 500gb you could also get the 200gb version for half the price ($10 USD).
You can look at their offer for yourself here:
Giga-Rdp.in - Hybrid RDP HDD & SSD, 3.20 GHz 6/12, Starting at €2.4 or $3 (FR, NL)
You should ask amartin99 for a demo (NL server) and then decide, but be quick about it before other people will take the offer and NL offer is out of stock.
Best regards
