Nowadays, MB SD Connect Compact 4 Plus Dell D630 is favored by the Mercedes owners.
But there are lots of people puzzled whether it is necessary to buy Dell D630 laptop for MB SD C4.
Recently, we obd2tool.com customer service have searched a great deal of customer feedback from different forum, and here are some of them.
—With the Dell D630’s dedicated serial port, there was no issue for me…. it was plug and play… I just loaded the HDD from the Seller into my Dell and all I needed to do was activate WIS/EPC and XENTRY/DAS with “activation keys”… I only use the Dell for MB Star C4 SD Connect purposes…
bought an older Dell D630 with a serial port and plan on buying MB SD Star C4 directly installed in a Dell D630 hard drive. No Virtual Machine issues.

C3 Star/ C4 actually specifies the computer or tablet used in the SDS environment… The T30 is rather slow but will get the job done.
If your ever in the market for a faster SDS laptop, the Dell 630 with at least 2Ghz and the speed improvement especially when using Xentry is like night and day.
—I advise buy SD Connect 4 which is connected with LAN cable rather than COM-port as Star C3. And pick up Dell 630 laptop if you are new to Mercedes daignosis, because all latest software (current 2015.7V) are pre-installed.
