ASUSTOR LOCKERSTOR 16R Pro (AS7116RDX) review

Research-based assessment: The LOCKERSTOR 16R Pro AS7116RDX is a 3U, 16-tray NAS aimed at a rack deployment that needs native SATA capacity and accepts an older platform. It is not the 2U, 12-tray AS7112RDX, and neither model's optional expansion figures should be treated as built-in bays. This assessment uses manufacturer documents; it does not report hands-on use, testing, measured throughput or an inspected seller unit.

Sixteen native SATA positions are the main distinction

ASUSTOR's exact English product page and hardware selector identify AS7116RDX as the 3U LOCKERSTOR 16R Pro. The base chassis has sixteen SATA positions for 3.5-inch HDDs or 2.5-inch HDDs/SSDs. Two separate M.2 sockets support specified NVMe and SATA SSD form factors for caching; they are not extra SATA trays. This 16-bay profile is the clear reason to compare it with the 12-bay AS7112RDX: the larger model uses an additional rack unit for four more native positions. The exact product page and hardware selector document the base layout.

Do not plan around the manufacturer's quoted expansion ceiling without reconciling the exact equipment. The current specification selector says a total of 28 positions with expansion, while English model/family datasheet text says 40. The difference is unresolved here; only the sixteen internal trays are used in this model assessment. Drive count also is not usable capacity: the choice of disks and RAID layout changes usable space, and the QIG directs buyers to check the exact model's compatibility list.

Two M.2 sockets are a separate layer

ASUSTOR lists two M.2 SSD positions separately from the SATA trays, with model support across NVMe and SATA form factors. Its installation guide warns not to mix PCIe NVMe and SATA AHCI modules in those two sockets and recommends that two installed SSDs be the same model. It directs the owner to the current compatibility list. The manufacturer describes the M.2 positions as cache; this review does not assume they are additional storage-pool capacity or that an SSD is included. The exact supported drive/firmware tuple remains a purchase check.

The documented RAID menu includes RAID 1. A possible setup is a mirror made by the owner from two compatible SATA drives, using two of sixteen trays and leaving fourteen open. The source documents no prepared array or data disks in the reference package. Initialization erases data already on installed disks, so preserve anything important first. RAID can help with a single drive failure, but does not protect against deletion, malware, a chassis failure or a lost site; keep an independent, recoverable backup.

Four Gigabit ports are not a built-in 10GbE connection

The base model lists four separate 1-GbE RJ-45 ports. The manufacturer's advertised 10/25/40/50-GbE options are PCIe add-in cards, not native ports or equipment this review assumes will arrive with a seller unit. The selector lists one PCIe Gen3 x8 slot and two Gen3 x4 slots for optional network or SAS cards. If a faster network is essential, check the exact card and supported slot, driver, transceiver or cable, switch, client and storage path as one system. Aggregating several links does not change the rating of one individual port, and advertised link rate is not a measured file-transfer result.

The exact product material lists a quad-core Intel Xeon E-2224, 8 GB of ECC DDR4-2666 UDIMM installed as one module, four memory slots and a 128-GB listed ceiling. The QIG says third-party memory is not guaranteed. These are specifications rather than a performance verdict; check software requirements and supported memory before buying or upgrading.

Rack, power and life-cycle checks matter

At 132 x 439 x 535 mm, the chassis is 3U high and 535 mm deep before accounting for rails, cable bends and service space. The exact selector reports 15.3 kg / 33.7 lb. An older U.S.-English comparison repeats 15.3 kg but gives 39.6 lb, an inconsistent conversion that should not be silently repeated as a second weight. Confirm the cabinet's usable depth, rail fit, airflow and loaded support before ordering. A physical chassis dimension is not the clearance a rack installation needs.

The selector lists two internal 550-W power supplies and the product materials describe redundancy. That is a component-level option, not proof that two cords use independent circuits or that a UPS/PDU path is resilient. The exact-model reference package lists two power cords, four Cat5e LAN cables, drive screws and a quick-start guide; it does not list data drives or rails. The current package reference is not a promise about the contents, condition or warranty of an individual reseller shipment. Ask for the exact delivered configuration and return/support terms.

Life-cycle evidence needs a date-aware check. The latest ASUSTOR status result returned on 2026-11-02 marks AS7116RDX discontinued, with software and technical support shown as supported and a five-year warranty duration. An indexed result from the prior month said generally available. ASUSTOR defines discontinued as no longer manufactured and says the warranty term begins from the receipt's purchase date, but the conflicting captures do not establish present inventory, remaining support or transferable coverage on any used or old-stock unit. Recheck the current status page and get written terms for the exact unit.

Who should compare it—and what to verify

AS7116RDX is relevant when sixteen native SATA trays, ECC-memory capability and a rack form factor are more important than built-in multigigabit networking. It is a poor fit for a buyer who needs a small desktop NAS, a shallow cabinet without measured clearance, or a native 10GbE port. The main trade-offs are 3U height, 535-mm chassis depth, one-Gigabit built-in ports, an earlier/discontinued status result, unresolved expansion totals and unknown seller configuration.

• Confirm AS7116RDX—not the 12-bay AS7112RDX, a rail bundle or a different family member—and check the seller's exact model and package.
• Check each drive model, capacity and firmware on the current ASUSTOR compatibility list; verify storage mode and usable capacity independently.
• Confirm rack depth, rails, airflow, two power connections and the upstream electrical path.
• Ask for unit condition, all trays and power supplies, included accessories, return terms, support channel and any remaining warranty documentation.
• If you need faster than one 1-GbE link, verify a specific optional PCIe card and every part of the matching network path before treating it as a workable plan.

The manufacturer datasheet, package reference and applicable AS71XXRDX installation guide are useful checks, but none establishes a current seller offer or the actual hardware condition of a particular unit.
