The cost-effective Patriot P210 SSD is ideal for people which are not interested in highly-sustained write speeds but more on capacity and this without breaking the bank. Its overall behavior is similar to the one we have seen with other QLC DRAM-less drives, meaning that until the SLC pseudo-cache fills up, the write speed will remain high but afterwards it will drop to as low as 13MB/s. This is a non-issue for most mainstream users and the drive is positioned correctly on the market price-wise.
