"Although it is underwater, bulk purchases by corporations are suppressed."

Since the HDD mining boom in 2021, the store has continued to limit the purchase of HDDs, but SSDs are new this week. "It's not like a graphics card at the time of the mining boom, but due to the long-standing shortage of semiconductors, we have temporarily restricted it," he said. So far, other stores haven't followed suit, but they share the same air of caution about SSD trends. One shop says, "We do not have public restrictions on purchases, but we do have some consultations regarding bulk orders from corporations." There is still no air of increased demand from buyers, and it seems that the anxiety on the supply side is increasing. In addition to the long-standing shortage of semiconductors, the background seems to be related to the suspension of 3D NAND production at Kioxia's domestic factories from late January. Another shop said, "There is information that Western Digital SSDs using Kioxia's 3D NAND will increase in price. It will be a while before the market's SSD supply will be affected, but the price reaction is quick." talk. In fact, PC SHOP Ark is said to have rushed to update the price of Western Digital SSDs. However, the supply of other brands has not been affected. For the time being, it seems a good idea to keep an eye on the trends in the SSD market as a whole.

The PC studio Akihabara BUYMORE store that arrived said, "Is it for people who want a low-priced SSD that supports PCIe 4.0?
