Compare NAS types, storage considerations and practical features before selecting your next network storage system.
The AMD Ryzen Embedded V1500B processor provides four cores, eight threads and a 2.2GHz clock speed. The TS-673A-8G includes 8GB SODIMM DDR4 memory and supports up to 64GB across two slots.
ECC memory is supported. The pre-installed non-ECC memory must be removed before using ECC modules because ECC and non-ECC memory cannot be installed together.
Two built-in 2.5GbE ports are backward compatible with 1GbE and 100MbE. The product information states that Port Trunking can provide up to 5Gbps combined transfer bandwidth.
Two PCIe Gen 3 x4 slots support compatible networking, SSD caching, additional USB connectivity, wireless networking or Fibre Channel expansion.
Two built-in M.2 2280 PCIe Gen 3 x1 slots support compatible NVMe SSDs for SSD caching and Qtier Technology. M.2 SSDs are not included.
Qtier can move data between M.2 SSDs, 2.5-inch SSDs and high-capacity hard drives according to access frequency.
The product information recommends a QNAP or third-party heatsink because M.2 SSDs can generate excessive heat.
The product information lists support for virtual machines, containerised applications and GPU pass-through, with VMware Ready, Microsoft Hyper-V, Citrix and Veeam Ready certifications.
QTS and QuTS hero use different file systems. All drives must be removed before switching operating systems.
It is a diskless six-bay AMD Ryzen NAS with dual 2.5GbE, two M.2 NVMe slots, two PCIe Gen 3 x4 slots and support for QTS or QuTS hero.
No. The supplied product name identifies a no-disk configuration, so compatible storage drives must be purchased separately.
The six hot-swappable bays support compatible 3.5-inch SATA hard drives and 2.5-inch SATA solid state drives.
It uses an AMD Ryzen Embedded V1500B four-core, eight-thread processor running at 2.2GHz.
The TS-673A-8G includes 8GB DDR4 memory and supports up to 64GB using two 32GB SODIMM modules.
Yes. ECC memory is supported, but the pre-installed non-ECC memory must be removed because ECC and non-ECC memory cannot be used together.
It includes two 2.5GbE ports that are backward compatible with 1GbE and 100MbE.
Yes. The product information states that Port Trunking can provide up to 5Gbps combined transfer bandwidth.
Yes. It includes two M.2 2280 PCIe Gen 3 x1 slots. M.2 SSDs are not included and are not hot-swappable in the built-in slots.
The two PCIe Gen 3 x4 slots can support compatible networking, SSD caching, additional USB, wireless networking or Fibre Channel expansion.
Yes. Both are supported, but all drives must be removed before switching because the operating systems use different file systems.
This product is covered by a three-year QNAP manufacturer warranty.
