The best SSDs 2021 – buying advice & tips

An SSD noticeably accelerates PC and notebook, but which SSD model is right for you. We give buying tips and buy the best SSDs of all classes.

The typical storage space of SDDs is between 240 and 4000 gigabytes. We recommend models with at least 240 GB for PCs and notebooks for office use, 512 GB for all-round notebooks and 1000 GB for all-round PCs. For gaming PCs, we recommend using a 2000 GB model right away – if your budget allows it. The built-in flash memory is important; the more information a cell has to store, the more the speed and service life are reduced. A distinction is made between SLC (1 bit per cell), MLC (2 bits per cell), TLC (3 bits per cell) and QLC (4 bits per cell).
Inexpensive SSDs in 2.5-inch format – our recommendations:
Crucial BX500
available with 240, 480, 1000 and 2000 GB for 30, 45, 100 and 160 euros

SSDs are available in three designs: 2.5-inch housing and M.2 plug-in cards are the most common formats, PCI Express plug-in cards are less common. You can only use M.2 if your notebook or the motherboard of your PC also has an M.2 slot. The advantage of M.2 and PCI Express cards: You do not need a data or power cable as with a 2.5-inch SSD.
