Built for work-intensive businesses and virtualization environments, the DiskStation DS3018xs 6-Bay NAS Enclosure from Synology is equipped with a PCIe 3.0 x8 slot that can accommodate a 10GbE network interface card for boosting network performance or a dual M.2 SSD adapter card for caching. It is equipped with six drive bays that are capable of natively supporting 3.5″ SATA hard drives, as well as 2.5″ SATA hard drives and SSDs. Using its six drive bays, this NAS will allow you to store and share a large number of files, including videos, music, photos, and documents with up to 16,000 user accounts and 2000 maximum concurrent connections.
The DS3018xs runs on Synology DiskStation Manager (DSM) OS, which is a browser-based operating system that helps to simplify managing your Synology NAS. Its CPU is a 2.2 GHz Intel Pentium D1508 Dual-Core with a burst frequency of up to 2.6 GHz, and its 8GB of DDR4 ECC RAM, which can be upgraded to 32GB, allows frequently-used files and applications to be quickly accessed. The NAS is capable of achieving read speeds of up to 2231 MB/s and sequential IOPS reads of up to 265,000. When connected to two DX1215 expansion units, up to 30 total drives are supported.
The 1.92TB SAT5200 SATA 2.5″ SSD from Synology is an enterprise-grade SSD built for select models of their NAS systems, including the FS6400, FS3600, and FS3400. It provides stable I/O performance and reduced latency for critical services and applications and is also able to handle mixed and intensive 24/7 workloads without reducing its endurance. All of these facets will provide users with a streamlined experience with minimal service disruptions.
This SSD has an overall capacity of 1.92TB, a SATA III 6 Gb/s interface, a 2.5″ / 7mm form factor, sequential read speeds of up to 530 MB/s, sequential write speeds of up to 500 MB/s, random reads of 98,000 IOPS, and random writes of 60,000 IOPS. It also features an endurance of 4581TB TBW (terabytes are written), 1.3 DWPD (drive writes per day), a 1.5 million hour MTBF (mean time between failures), and an UBER (uncorrectable bit error rate) of <1 sector per 1017 bits read.
