Yesterday, we covered the Synology 8 bay RackStation RS1221RP+ (Diskless) rackmount NAS unti which is currently on sale for its lowest ever price. You can find the details about it as well as the purchase link in this dedicated article here. The unit supports 3.5-inch hard disk drives and thus if you are looking for compatible high-capacity HDD options then Western Digital (WD)"s 24 TB Gold model is a great buy as it is currently at its lowest ever price (purchase link under the specs table down below).
The Gold series is built around enterprise workloads, so the 24TB model includes WD’s HelioSeal technology. That’s essentially a helium-filled enclosure, which reduces internal turbulence and allows more platters to fit in the same 3.5‑inch form factor.
It is of course based on CMR or conventional magnetic recording technology which means it is ideal for 24x7 operations with little or no worry of issues.
Other interesting features include OptiNAND which caches metadata, among other things, to non-volatile iNAND UFS memory instead of simply relying only on the typical volatile DRAM memory. In case of a power loss, the NAND controller quickly transfers the necessary information from the volatile to non-volatile section thus saving the system from potential data loss.
