Differences between Dell Vostro 3250 and Lenovo ThinkCentre M900 Small

If you are looking for a more modern desktop, then you should go with the Dell Vostro 3250 which was released in 2016. The Lenovo ThinkCentre M900 Small is older and entered production in 2015.

Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

Processor

The two models have the same generation of Intel processors. We think that the 6 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The Lenovo ThinkCentre M900 Small has 4 RAM slots while the Dell Vostro 3250 has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.

The Lenovo ThinkCentre M900 Small is using the faster 2133 MT/s RAM. The Dell Vostro 3250 is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Lenovo ThinkCentre M900 Small as it has the ability to run 64 GB of RAM. The Dell Vostro 3250 can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Lenovo ThinkCentre M900 Small has 8 USB ports. The Dell Vostro 3250 is inferior in this regard and packs 6 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.

Unfortunately, only the Lenovo ThinkCentre M900 Small has a DisplayPort. The Dell Vostro 3250 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

The Dell Vostro 3250 comes with an HDMI port, while the Lenovo ThinkCentre M900 Small does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).

SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the Lenovo ThinkCentre M900 Small is better equipped as it comes with 3 SATA slot(s), while the Dell Vostro 3250 has 2 slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell Vostro 3250, nor the Lenovo ThinkCentre M900 Small has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!

Power Supply

Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Dell Vostro 3250 comes with a decent 180 Watt PSU, but the Lenovo ThinkCentre M900 Small has a more powerful one rated at 210 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
