Prices for various PC parts often have a huge range, depending on items quality, performance, and availability. Some CPUs are $100, some are $1000, and some cannot be bought for love or money. Some other items have a much smaller range of prices, and this can be seen when we look at PC memory and storage (including RAM and hard drives). Memory and storage are offered by a large number of sellers, and thus the options are competitively priced. Most options that are similar in speed and capacity tend to be close to each other in price, making it easy to track and compare.

With time, long-term and short-term computer memory always sees a downward trend in price, with the only exception being when a factory is burned or flooded or something. Once certain items (or capacities) can be reliably found for a particular price, we overhaul our memory recommendations to recommend better/larger components, for the same price.
