# TeamGroup Cardea A440 Pro 8TB Review — Flagship Gen4, Maxed Out (2026)

The TeamGroup Cardea A440 Pro 8TB doubles most flagships on capacity — 7,200 MB/s reads, 6,000 TBW of endurance and a graphene heatsink fitted for the PS5.

Quick answer: The TeamGroup Cardea A440 Pro 8TB exists for two buyers: the PS5 owner who wants to stop managing storage forever — it meets Sony's speed, size and capacity criteria with the heatsink pre-fitted — and the creator or homelab builder who genuinely needs 8 TB of fast TLC behind a DRAM cache and 6,000 TBW of endurance. Skip it if 4 TB covers the library: the 4TB A440 Pro rates faster at 7,400/6,900 MB/s and costs meaningfully less, while the Sabrent Rocket 4 Plus 8TB is the rare direct rival. Everyone else should treat this as a niche flagship — superb at its one job, unnecessary for mainstream builds. Its endurance doubles the 4TB model's, its heatsink comes pre-fitted, and nothing about the platform is cut down to reach the capacity.

## Performance

TeamGroup rates the A440 Pro 8TB at 7,200 MB/s sequential reads and 6,000 MB/s sequential writes over PCIe 4.0 x4, with random performance rated up to 900K read and 1,000K write IOPS. Those figures trail the 2TB and 4TB variants — 7,400/6,900 MB/s and 1,000K/1,000K IOPS — reflecting the larger capacity's die configuration, and they remain comfortably within striking distance of the Gen4 ceiling, where only PCIe 5.0 hardware goes meaningfully faster.

The E18 platform's character is well documented by the family's review history: Tom's Hardware, The SSD Review and KitGuru all tested A440 Pro capacities and found strong Gen4 performance, with the DRAM cache holding behavior steady well past the SLC cache wall — the advantage a DRAM-equipped flagship holds over the DRAM-less budget tier. For a PS5, the rated read speed clears Sony's 5,500 MB/s recommendation with room to spare, and console game loading is limited far more by the console's own scaler than by any Gen4 drive's last few hundred MB/s. As a working archive, rated-class writes move a 100 GB project in under twenty seconds. Thermals are the one watch item at 8 TB: the graphene spreader helps, but sustained loads in a cramped slot benefit from case airflow — the aluminum fin variant exists for exactly this reason.

## Endurance, TBW & Warranty

TeamGroup backs the A440 Pro 8TB with a 5-year limited warranty rated to 6,000 TBW of host writes, whichever arrives first — the largest endurance rating in the Cardea consumer range, double the 4TB model's 3,000 TBW and nearly ten times the 1TB variant's 700 TBW. The scale is worth translating: at a heavy 50 GB of writes per day, 6,000 TBW represents well over three centuries of service, so the calendar term is the only realistic limit even for demanding archival workloads. The spec sheet lists MTBF at 3,000,000 hours, a population-level reliability statistic rather than a promise for any individual drive. Warranty service runs through TeamGroup's support channels with proof of purchase. The endurance rating assumes the drive operates within its rated 0-70°C range, which is what the pre-fitted graphene or aluminum heatsink is there to protect.

## Pros and Cons

**Pros:**

- 6,000 TBW endurance with 5-year warranty
- 7,200/6,000 MB/s rated speeds
- 900K/1,000K rated random IOPS
- Phison E18 with DRAM cache
- Micron 176-layer TLC NAND
- Graphene heatsink pre-fitted, PS5-clearance
- 8 TB maxes out PS5 storage expansion
**Cons:**

- Writes derated to 6,000 vs 6,900 on 4TB
- Random reads rated 900K vs 1M on smaller models
- 8 TB commands a large per-terabyte premium
- Overkill for typical boot-and-games builds


## Verdict

The TeamGroup Cardea A440 Pro 8TB exists for two buyers: the PS5 owner who wants to stop managing storage forever — it meets Sony's speed, size and capacity criteria with the heatsink pre-fitted — and the creator or homelab builder who genuinely needs 8 TB of fast TLC behind a DRAM cache and 6,000 TBW of endurance. Skip it if 4 TB covers the library: the 4TB A440 Pro rates faster at 7,400/6,900 MB/s and costs meaningfully less, while the Sabrent Rocket 4 Plus 8TB is the rare direct rival. Everyone else should treat this as a niche flagship — superb at its one job, unnecessary for mainstream builds. Its endurance doubles the 4TB model's, its heatsink comes pre-fitted, and nothing about the platform is cut down to reach the capacity.

## Frequently Asked Questions

### Is the TeamGroup Cardea A440 Pro 8TB compatible with the PS5?

Yes — it is one of the few drives that maxes out Sony's spec. Sony's published requirements call for a PCIe 4.0 x4 NVMe drive with 5,500 MB/s or faster recommended reads, dimensions up to 110 x 25 x 11.25 mm including a heatsink, and capacities from 250 GB to 8 TB. The A440 Pro 8TB clears every line: 7,200 MB/s rated reads, a pre-fitted graphene heatsink at 3.7 mm height, and 8 TB of raw capacity. TeamGroup markets the series specifically for PS5 expansion. Expect roughly 7.4 TB of usable space after the console formats the drive.

### Is the TeamGroup Cardea A440 Pro 8TB good for gaming?

Yes, with a niche framing. On a PC, game loading is read-driven and low-queue, so the 7,200 MB/s rating delivers load times indistinguishable from any quality Gen4 flagship — the capacity is what matters, holding a vast library without juggling installs. The DRAM cache and 6,000 TBW endurance also make it comfortable with repeated install churn. On PS5, it is a flagship option: fully within Sony's published requirements including the 8 TB maximum. The honest caveat is fit for purpose — a 1 TB or 2 TB drive serves a typical gaming PC better per dollar spent.

### What is the TBW endurance of the A440 Pro 8TB?

The 8TB model is rated at 6,000 TBW of host writes under a 5-year limited warranty, whichever arrives first. Endurance scales across the A440 Pro range at roughly 0.75 TBW per gigabyte: 700 TBW at 1 TB, 1,400 TBW at 2 TB, 3,000 TBW at 4 TB and 6,000 TBW here. For context, 6,000 TBW equals about 82 years of writing at 200 GB per day — far beyond any consumer workload — so the five-year calendar term is the practical limit. TeamGroup defines TBW to JEDEC standards, and the rating assumes the drive stays within its 0-70°C operating window.

### Does the Cardea A440 Pro have a DRAM cache?

Yes — unlike TeamGroup's budget G50 and Z44L lines, the A440 Pro is a full DRAM-equipped flagship. KitGuru's teardown of the family found the Phison PS5018-E18 controller paired with DDR4 DRAM for the flash translation tables, alongside the SLC cache and Micron 176-layer TLC NAND. The practical benefit shows in sustained writes, where performance holds steadier past the SLC cache wall, and in heavy multitasked small-file work, where latency stays lower than DRAM-less designs manage. It is one of the core reasons this platform sits in the flagship tier rather than the value tier.

### Why is the 8TB model rated slower than the 4TB?

TeamGroup's official capacity table rates the 8TB at 7,200/6,000 MB/s against 7,400/6,900 for the 2TB and 4TB, with random reads at 900K IOPS versus 1,000K. The difference comes from die configuration: fitting 8 TB onto a single-sided M.2 2280 board changes how channels, CE pairs and dies load the controller, and manufacturers commonly derate the largest capacity slightly as a result. In practice the gap is a few hundred MB/s at benchmark-level queue depths — invisible in game loading, console use or general desktop work, and only marginally visible in sustained sequential transfers.

### How does the A440 Pro 8TB compare to the Sabrent Rocket 4 Plus 8TB?

Both are rare 8 TB Gen4 flagships built on the Phison E18 platform, so top-tier Gen4 performance and platform behavior are in the same family. The Sabrent positions itself as a premium enthusiast brand with its own heatsink options and typically prices the 8 TB at a steep premium; the A440 Pro counters with a graphene heatsink included as standard, PS5-focused marketing, and TeamGroup's 5-year, 6,000 TBW coverage. Real-world differences come down to availability and current pricing rather than architecture. Buyers should compare both on those terms at purchase time — neither is the wrong choice on specification.
