Compact M.2 2230 NVMe SSD

The Micron 2500 512GB drive fits the short M.2 2230 slot found in handheld consoles, ultrabooks and mini PCs. Its single-sided layout leaves room for tight motherboards. The PCIe 4.0 x4 interface delivers up to 6,600 MB/s sequential read and 3,650 MB/s sequential write. Random write reaches 860,000 IOPS for responsive multitasking.

PCIe 4.0 x4 practical limits

The four-lane Gen 4 link caps theoretical throughput at roughly 8 GB/s, so the 6,600 MB/s read figure sits near the ceiling. Real-world speed depends on host thermal limits and firmware tuning. The controller uses Host Memory Buffer instead of onboard DRAM, which reduces component count but leans on system RAM for mapping tables. Endurance is rated at 200 TBW for this capacity.

232-layer QLC NAND decides suitability

Micron's 232-layer QLC packs high density into the 2230 footprint, enabling 512GB on a single side. QLC writes slower than TLC once the SLC cache fills, so sustained heavy writes will throttle. Buyers needing constant video capture or database work should verify workload fit; light gaming and OS duties match the design target.

Questions about this item

Which capacity should I pick for a handheld or ultrabook upgrade?

The 512GB model provides 200TB TBW endurance and fits the single-sided M.2 2230 slot used in Steam Deck, Surface, and similar compact devices.

What does the 6,600 MB/s sequential read figure mean in daily use?

It enables faster boot times, quicker game level loads, and snappy file transfers on any PCIe 4.0 x4 platform that can sustain Gen4 speeds.

Does the PCIe 4.0 x4 interface cap performance on older Gen3 systems?

Yes, the drive will run at PCIe 3.0 x4 speeds on Gen3 hosts, limiting sequential throughput to the host's Gen3 ceiling while retaining full NVMe 1.4c feature support.
