Best SATA SSDs for the DH4300 Plus

All bays on this model take standard 2.5-inch SATA SSDs, so pick by capacity and budget rather than speed.

Which should you pick

Why SSDs are a niche choice on this particular NAS

The DH4300 Plus has zero M.2 slots, so there is no option here for an NVMe cache tier or an NVMe storage pool sitting alongside the main array. Every SSD you fit goes into one of the four SATA bays, competing directly with hard drives for the same space and the same RAID options (Basic, JBOD, RAID0, RAID1, RAID5, RAID6). That changes the maths compared with NAS units that do have M.2 slots, where a small fast SSD cache is a genuinely useful add-on rather than the whole storage solution.

With an 8-core ARM CPU and 8GB of soldered RAM, this box is built for efficient file serving, backup targets and light multimedia duty, not heavy multitasking or transcode-hungry Plex libraries. Because it also lacks reliable hardware transcoding, streaming to devices that cannot direct-play your files will struggle regardless of whether the underlying storage is SSD or HDD. So the case for SATA SSDs here rests almost entirely on silence, heat and drop resistance, useful in cramped or shared spaces, rather than any meaningful throughput gain over 2.5GbE.

Be honest about the cost per TB
