6Gbps 2.5-inch SATA SSD to 3.5-inch SAS drive adapter for dual-controller servers The QDA-SA2 adapter is designed for dual-controller servers and QNAP Enterprise ZFS NAS and allows the use of a 2.5-inch SATA 6Gbps SSD in a 3.5-inch SAS drive bay. It can be installed in a QNAP NAS or server (Windows®, Linux®) - providing the capacity to replace an expensive SAS drive with a more-affordable yet high-performing SATA SSD. Use more affordable 2.5-inch SATA SSD in a 3.5-inch SAS drive bay. (SSD sold separately) Up to 6 Gb/s file transfer speeds. The installed SATA SSD can share SAS dual-port advantages for higher reliability. Architecture diagram SAS dual-port advantage for fault tolerance SAS features dual porting for redundancy, eliminating single points of failure and allowing for higher reliability and performance. Although SATA 6Gbps SSDs provide high-performance and affordable storage, the lack of dual-port support makes them unsuitable for dual-controller environments. By installing a SATA SSD with the QDA-SA2 into a dual-controller Enterprise ZFS NAS or a dual-controller server, the SATA SSD can share these SAS dual-port advantages to ensure a high-availability, fault-tolerant enterprise storage environment. Designed for dual-controller servers and Enterprise ZFS NAS The QDA-SA2 can be easily installed in a dual-controller Windows®/Linux® SAS server and the 3.5-inch disk tray of an Enterprise ZFS NAS (Disk tray model: SP-ES-TRAY-WOLOCK). (QES 2.0.0 (or later) is required for the NAS)

Trusted seller

The website provided detailed information, and I received a brand new PNY version RTX Pro 6000 at a reasonable price. Shipping was fast. My only suggestion is to confirm the customs clearance agency with the customer before exporting to Canada to avoid delays. Overall, shopping here is trustworthy.

Fast and easy transaction! Will buy from them again!

Although the product itself was unsucc6for our purposes, the customer uce was exceptional. I would gladly go business with this company again.

I would certainly recommend Saitech, Inc. for all your IT solutions. Erwin our sales rep and his team are fantastic to work with.

As a dark matter researcher building a university-grade dual-node system at home, I sourced an RTX Pro6000 Blackwell GPU from eSaitech—paired with i9-14900Ks, 128GB RAM per node, 20TB of NVMe across 4/4/8/4TB partitions, and Ubuntu 24.04. The build was flawless—until I accidentally charged the $8,000 GPU to my checking account via PayPal instead of the intended credit card. That misstep triggered a cascade of issues across PayPal, my bank, and eSaitech’s Shopify backend. Enter MaryLou from eSaitech customer service. She didn’t just help—she orchestrated a full recovery: coordinating RMA and accounting to reverse the charge, reprocess it correctly, and clear the default with PayPal. I was stunned. This wasn’t just good service—it was spectacular. From a company I’d never worked with, and to whom I technically owed money. The GPU arrived fast, at the lowest price I could find anywhere. But it’s the integrity and responsiveness of their team that truly impressed me. I don’t even know how to thank them properly. If you’re sourcing high-end components and value not just price but people, eSaitech earns my highest recommendation. Note my system below -
