Trusted by our customers
"At Qloudea, we've been working with Synology drives and memory for several years, selling tens of thousands of units. We've found them to be the most reliable in their respective categories, and the DSM operating system is much more stable with these drives and memory than with any other brand. Working with Synology guarantees minimal RMAs and the highest data reliability for our customers." - Qloudea, CEO, Alejandro Serrano Notes: Performance testing was conducted by Synology using 12 drives on an RS2423RP+, configured using RAID 5 and tested using FIO with 1 MB block sizes. Results are for reference only. Actual performance may vary depending on workload, testing methods, and how devices and software are configured. The compared models consist of similar-class NAS drives in Synology’s testing lab, all of which were commercially available in 2023. The HAT3310-8T has a rotational speed of 7,200 RPM, while the rotational speeds of drives from other manufacturers may vary. Drive manufacturers may continue to update or refresh products within this category over time. The data represents results measured in Synology’s lab at the time of testing. Performance testing was conducted by Synology using 8 drives on a DS1821+, configured using RAID 5. Results are for reference only. Actual performance may vary depending on workload, testing methods, and how devices and software are configured. Based on Synology customer support statistics over the past few years, the use of validated drives results in nearly 40% less storage-related issues and faster issue diagnostics and resolution. The average firmware update time for Synology drives is based on tests conducted using an RS2821RP+ unit fitted with 16 Synology HDDs. For 3rd-party drives, the average update time was calculated by multiplying the time required for updating a single drive installed on a RS2821RP+ unit by 16. Mean Time Between Failure (MTBF) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTBF. Workload rating is defined as the amount of data written, read, or verified by commands from a host system. The warranty period starts from the purchase date as stated on your receipt of purchase. Learn more about our limited product warranty policy. Specifications may vary by capacity.
