The drive was demonstrated on the show floor through a performance test video, alongside a liquid-cooled E1.S model, mixed-mode QLC solutions, and dual-port E3.S drives spanning TLC and QLC. ![DapuStor 512TB R6060 E2 SSD standing on the FMS 2026 booth beside an NVM Express member sign](https://www.storagereview.com/wp-content/uploads/2026/08/StorageReview-DapuStor-512TB-E2-FMS.jpg) The 512TB figure resets the top of the announced-capacity table. The largest SSD we have tested is Micron’s [245.76TB 6600 ION](https://www.storagereview.com/review/micron-6600-ion-245tb-ssd-review-a-quarter-petabyte-per-drive-bay), and DapuStor’s own R6060 came through the lab in May in its [122.88TB configuration](https://www.storagereview.com/review/dapustor-r6060-122tb-review-read-heavy-gen5-qlc-at-scale), where its read-heavy Gen5 QLC design held up well at scale. We have since put the 6600 ION up against a hard drive array in a [power and rack-density comparison](https://www.storagereview.com/review/micron-6600-ion-245tb-swap-the-hard-drives-power-an-nvl72-for-free). DapuStor has not published performance specifications for the 512TB model, so for now, the claim rests on the show-floor demonstration. ## 512TB R6060: A Petabyte in Two Drives The new R6060 arrives in next-generation EDSFF form factors, including E3.L and E2, the emerging EDSFF variant aimed at maximum-capacity drives. DapuStor positions the drive for large AI datasets and capacity-intensive infrastructure, with the familiar density argument: fewer drives per rack for a given capacity target, which reduces slot count, power draw, and overall TCO. Those are the vendor’s claims, and they will ultimately depend on pricing, endurance, and performance figures that the company has not yet disclosed. ![DapuStor R6060 512TB E2 SSD render showing the long EDSFF E2 form factor with its edge connector](https://www.storagereview.com/wp-content/uploads/2026/08/DapuStor-R6060-512TB-E2-render.jpg) ## Liquid-Cooled E1.S for Dense AI Servers Alongside the capacity play, DapuStor introduced an 8TB R6 PCIe 5.0 TLC SSD in E1.S with cold-plate liquid-cooling support. The compact form factor targets dense, GPU-heavy AI servers and liquid-cooled data center environments, where flash increasingly shares the cooling loop with the accelerators it feeds. ## Mixed-Mode QLC and Dual-Port E3.S The J5060 QLC Series supports mixed SLC and QLC deployment, letting a system carve a high-performance flash tier and a high-capacity QLC tier within the same architecture. DapuStor also showed R6 E3.S dual-port enterprise SSDs in both TLC and QLC configurations, with TLC models scaling to 30.72TB and QLC to 61.44TB; dual-port support adds path redundancy for high-availability enterprise and AI storage systems. ![DapuStor R6060 QLC SSD label detail from StorageReview lab testing]() DapuStor ran the show from Booth #115, and on the final day, its VP of R&D, Xiang Chen, presented a technical session on optimized solutions for large-capacity QLC SSDs in the AI era. The company was one of several vendors leaning hard into QLC capacity at [FMS 2026](https://www.storagereview.com/news/sk-hynix-at-fms-2026-16-high-hbm4-wafer-bonded-375-layer-nand-and-a-tiered-memory-pitch), where the show’s throughline was flash positioning itself as the capacity tier for AI infrastructure. No availability dates or pricing were announced for the 512TB R6060; we will follow up as the drive moves toward production, and our full test data on the current R6060 is in the [122TB review](https://www.storagereview.com/review/dapustor-r6060-122tb-review-read-heavy-gen5-qlc-at-scale). **Engage with StorageReview** [Newsletter](https://www.storagereview.com/storage_newsletter) |  [YouTube](https://www.youtube.com/user/StorageReview "Opens in a new window") | Podcast  [iTunes](https://podcasts.apple.com/gb/podcast/storagereview-com-storage-reviews/id1060681115 "Opens in a new window")/ [Spotify](https://open.spotify.com/show/1y6VnznABhHeOSMOmbDTz0 "Opens in a new window") |  [Instagram](https://www.instagram.com/storagereview/ "Opens in a new window") |  [Twitter](https://twitter.com/storagereview "Opens in a new window") |  [TikTok](https://www.tiktok.com/@storagereview?
