Solidigm will ship data-centre SSDs from a new Taiwan contract site in December
SK hynix's Solidigm is adding a contract SSD site in Taiwan, home of the firms that ship over 90% of AI servers, with drives delivered from December. Using a contractor lets it sell into NAND prices eight times last year's without putting fab money on the island.

What happened
- Solidigm told customers in a notice last month that drives from the new site will be supplied on the same terms as its existing output.
- Solidigm has no NAND fab in Taiwan and already contracts part of its drive production there to firms including Powertech Technology and Pegatron.
- SK hynix, counting Solidigm, ranked second in enterprise SSDs in the second quarter with a 21.1% share, behind Samsung Electronics at 35.1%, according to TrendForce.
- SK hynix is building M17, an 80 trillion won NAND fab in Cheongju targeted to start operating in 2029, and is expanding its second plant in Dalian.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- constraint Because the Taiwan site adds drive output but no wafers, faster growth in SK hynix's NAND bit supply still depends on the Dalian expansion and on M17's 2029 start.
- exposure Samsung's 14-point lead in enterprise SSD share now faces a rival supplying drives from Taiwan, where the companies that build SSDs into AI servers are concentrated.
- exposure Buyers of a Solidigm IPO near $150 billion would be paying at NAND prices eight times last year's, and would take the loss if that price falls back.
Enterprise SSD revenue at the top five suppliers doubled in three months to about $37.6 billion in the second quarter, according to TrendForce [10]. The first quarter was therefore near $18.8 billion [1]. If SK hynix's 21.1% share [11] is measured against that pool, the group sold roughly $7.9 billion of enterprise drives in the quarter [2]. NAND prices have moved further over a longer stretch. DRAMeXchange put September's average at $30.61, eight times the level a year earlier [12], or about $3.83 then [3].
According to industry sources cited by the Seoul Economic Daily, Solidigm disclosed the Taiwan site to customers in a product change notification last month [1]. The move fits three readings. The first is that Solidigm expects AI storage demand to last and wants supply next to the firms that ship more than 90% of the world's AI servers [5]. Foxconn, Quanta, Wistron and Wiwynn joined Nvidia's DSX data-centre ecosystem in May [6], and AMD singled out Wiwynn, Wistron and Inventec when it announced a $10 billion Taiwan investment the same month [7]. The second is that contract capacity is the easiest kind to give back if NAND comes off eight times last year's price. The third is share, in a market Samsung leads [11]. In that market server makers sit between the drive suppliers and the Big Tech data centres as, in effect, intermediate distributors [4].
I think the second and third readings carry more weight than the first. A company betting on years of demand puts 80 trillion won into a fab like M17 in Cheongju, due to run in 2029 [8], and SK hynix is doing exactly that in Korea. The Taiwan site is the part of the plan it can unwind, or rather, the part where the production lines belong to someone else [3]. The evidence against that view is the NT$16 billion Solidigm put into Nanya Technology to secure locally sourced DRAM for its drives [13]. An equity stake in a Taiwanese chipmaker is harder to walk away from than a manufacturing contract.
Solidigm is weighing a listing at a valuation of up to $150 billion [9], a number set while NAND sells at those eight-fold prices [12]. Annualising the group's second quarter gives about $31.7 billion of enterprise SSD revenue [5]. The top of the range is about 4.7 times that run rate [6], and the run rate includes SK hynix's own drives as well as Solidigm's.
The view above fails if NAND prices fall and Solidigm keeps adding Taiwan contract sites anyway. That would show the network exists to hold a place with the server builders at any price.
What to watch
- DRAMeXchange's October and November NAND averages against September's $30.61, the price level the contract-site expansion is selling into.
- TrendForce's third-quarter enterprise SSD ranking, and whether SK hynix narrows Samsung's 14-point share lead once Taiwan output starts in December.
- Solidigm's IPO filing, and whether the valuation lands near the $150 billion top of the range being weighed.
