Best SATA SSDs for the DH2300

All three fit the two 2.5-inch bays directly, since this model has no M.2 slots at all.

Which should you pick

Why SSDs are a niche choice on this model

The DH2300 has no M.2 slots whatsoever, so there is no possibility of an NVMe cache or an all-flash NVMe pool here. Every SSD you fit has to go into one of the two 2.5-inch SATA bays, sharing the same RAID options as any hard drive would: Basic, JBOD, RAID0 or RAID1. There is no SHR, so with two bays your realistic redundant option is a straight RAID1 mirror, which halves your usable capacity regardless of drive type.

The 8-core Rockchip ARM CPU and 4GB of soldered LPDDR4X RAM mean this box was never designed to push huge sustained throughput or juggle heavy multitasking. A 2.5GbE network port caps real-world transfers at around 280MB/s in good conditions, well within what even a budget SATA SSD or a 7200rpm CMR hard drive can sustain. In practice, the SSDs on this list will not make your file transfers meaningfully faster than a good CMR HDD would, because the network and CPU are the limiting factors here, not the drive.

Where SSDs genuinely help is in access latency and noise. If the DH2300 sits in a bedroom or office and you want it silent with instant-on file access for a modest dataset, such as a small RAID1 mirror for documents, project files or a Time Machine style backup target, SSDs are a reasonable choice. For anything approaching the 32TB per bay maximum, the cost difference over CMR HDDs becomes very hard to justify.
