Compare Crucial T705 4TB and TeamGroup MP44 4TB: prices, speeds, $/TB. Which to buy in July 2026? Full spec breakdown.
Crucial T705 4TB vs TeamGroup MP44 4TB pits two different generations against each other at 4 TB. The question isn't which is faster on paper — that's settled — it's whether the bandwidth gap shows up in your specific workload.
Hardware-wise, the Crucial T705 4TB runs on the Phison E26 — the first widely-deployed Gen 5 controller, capable but thermally demanding. The TeamGroup MP44 4TB pairs MaxioTech's MAP1602 silicon, the default choice for budget Gen 4 drives in 2024-2026.
There's a modest pricing advantage for the TeamGroup MP44 4TB: $128.25/TB compared with $153.25/TB. For typical gaming and productivity, this becomes the deciding factor when specs are close.
Read speeds favor the Crucial T705 4TB: 14,500 MB/s versus 7,400 MB/s for the TeamGroup MP44 4TB, a 49% advantage. Sequential-heavy workloads notice; transactional workloads don't.
The Crucial T705 4TB writes about 53% faster (12,700 MB/s vs 6,000 MB/s). Whether that matters depends entirely on what you write to the drive — gameplay capture and large project saves benefit, browsing and gaming do not.
The Crucial T705 4TB carries a dedicated DRAM chip for FTL (Flash Translation Layer) mapping; the TeamGroup MP44 4TB relies on HMB (Host Memory Buffer), borrowing 64 MB from system RAM. The practical gap shows up only under sustained random write loads.
For PS5 expansion, both are PCIe Gen 4 M.2 2280 drives that meet Sony's minimum spec (7,400 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the TeamGroup MP44 4TB. The leap from Gen 4 to Gen 5 doubles peak throughput on paper but produces single-digit-percent improvements in game load times, OS boot, and most productivity benchmarks. The TeamGroup MP44 4TB is the better default unless you have a specific workload that needs the extra lanes. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Crucial T705 4TB's 12,700 MB/s sustained write speed. Both drives use the 2280 form factor, which is too long for Steam Deck or ROG Ally — you'd need a 2230 variant if either manufacturer offers one, or a dedicated handheld-format drive instead.
Market context: the Crucial T705 4TB ranks #2 of 6 Gen 5 4 TB drives we track by $/TB, while the TeamGroup MP44 4TB ranks #2 of 6 Gen 4 4 TB drives. That puts at least one of them near the top of the value table — a reasonable head-to-head to be choosing from.
As of July 27, 2026, these tracked drives undercut both the Crucial T705 4TB and TeamGroup MP44 4TB on $/TB:
Pick the Crucial T705 4TB if you value meaningfully faster reads (14,500 MB/s), higher sustained writes (12,700 MB/s), and a dedicated DRAM cache chip. Crucial drives benefit from being a direct Micron product — the same NAND that powers competitors' drives, but at lower margins.
Pick the TeamGroup MP44 4TB if you value the lower retail price ($513 vs $613), and better $/TB economics ($128.25/TB). Budget-tier drives like the TeamGroup MP44 4TB have closed the gap with premium NVMes — the MAP1602 controller is genuinely competitive for everyday workloads at half the price.
