ADATA LEGEND 710 1000GB

The ADATA LEGEND 710 1000GB is a DRAM-less NVMe SSD typically pairing a 4-channel Silicon Motion SM2263XT controller with 3D NAND. To offset the lack of onboard DRAM it uses Host Memory Buffer (HMB) to cache the logical-to-physical address table in system RAM, which limits peak sequential throughput to about 2,400 MB/s on PCIe Gen3. Thermal analysis indicates the controller runs in conservative thermal envelopes due to modest bandwidth and power draw; the drive ships with a low-profile aluminum heat spreader and NAND source may vary by batch.

Hardware Alternatives

• ADATA XPG SX6000 Lite: shares nearly identical controller architecture and performance profile
• ADATA SWORDFISH: shares nearly identical controller architecture and performance profile
• Crucial P2: similar DRAM-less design, prone to sustained write slowdowns once SLC cache is exhausted
• Kingston NV1: occupies the same hardware segment with variable bill-of-materials and comparable random I/O
• Samsung 980 1000GB: uses a more advanced proprietary controller to achieve higher sequential speeds and IOPS
• WD Blue SN570: positioned above this tier with controllers tuned for higher sequential speeds and IOPS
