China eSSD Orders Shrink as Samsung and SK Hynix Redirect Supply to U.S. Cloud Giants
nashnova research
China's tech majors are cutting enterprise SSD purchases for the second half of 2026, and Samsung and SK Hynix are rerouting that supply to US hyperscalers — a shift that means the center of gravity in global NAND demand is migrating from China to the US, reshaping Korean chipmakers' customer mix in real time.
Why are Chinese orders shrinking?
Alibaba, Baidu, and Tencent have placed eSSD orders — enterprise solid-state drives, the high-performance storage workhorses of data centers — below early-year expectations, with cuts concentrated in H2 2026.
The root cause: tightening US export controls on Nvidia and AMD AI chips plus HBM — high-bandwidth memory, the fast RAM AI training demands — have stalled China's AI infrastructure investment.
This means → Chinese firms aren't losing appetite for storage; the upstream AI chips they need are blocked, and downstream storage demand falls with them.
Can US cloud giants absorb the redirected supply?
Industry analysts expect the reallocation to leave total global NAND demand largely intact — US hyperscalers are set to take what China no longer buys.
Global data-center storage remains tight; the shortage may persist into 2027–2028, keeping Korean suppliers' market window open.
In plain terms = the pie hasn't shrunk — it moved from one table to another. As long as global AI buildout keeps accelerating, Samsung and Hynix won't lack buyers.
What could go wrong on the US side?
Korean securities analysts warn that after the 2026 US midterms, some newly elected governors are pushing to restrict new data-center construction.
If cloud firms delay infrastructure purchases as a result, follow-on orders for QLC SSDs — four-level-cell drives prized for high capacity and low cost in data-center expansion — could shrink, weakening storage makers' pricing power.
This means → Korean chipmakers are shifting their bet from China to the US, but US policy is no sure thing either — whether the demand migration holds depends on the actual pace of American data-center investment.
How far along is China's domestic alternative?
YMTC's (长江存储) enterprise SSD revenue is estimated to remain outside the global top five for now; a near-term high-end replacement for Korean suppliers looks unlikely.
Yet YMTC's trajectory remains a long-term variable: China's domestic semiconductor supply chain keeps advancing, and the substitution path is not closed.
This reflects a deeper strategic picture — for Samsung and SK Hynix, the real challenge isn't losing Chinese orders per se; it's whether they can keep locking in the world's hungriest AI-infrastructure buyers, wherever those buyers happen to be.
