# Inland TN470 2TB: fast, efficient PCIe 4.0 storage (2026)

The Inland TN470 2TB is a single-sided, DRAM-less PCIe 4.0 NVMe drive that Tom's Hardware rated efficient, fast, and inexpensive, now with double the 1TB model's endurance.

Quick answer: The Inland TN470 2TB suits gamers, content creators, and PS5 owners who want flagship-tier PCIe 4.0 speed, a large game or media library, and a genuinely long 6-year warranty without paying flagship-tier prices. It's a slightly weaker choice for buyers doing constant large sustained writes, where a DRAM-equipped drive holds sequential speed more consistently past the cache limit. Buyers who want a more widely available alternative outside Micro Center's retail channel should look at the WD Black SN770. Overall, the TN470 2TB extends the line's efficient, fast, and inexpensive reputation with properly-scaled endurance for the capacity.

## Performance

Inland rates the TN470 2TB at up to 7,300 MB/s sequential reads and 6,400 MB/s sequential writes over PCIe 4.0 x4, matching the 1TB capacity's rated speeds. Random IOPS figures aren't independently confirmed for this exact capacity, so treat any specific number seen elsewhere with caution.

As with the 1TB model, the TN470 2TB leans on an SLC write cache to sustain its rated numbers; once a large sustained transfer exhausts that cache, write speeds drop toward the native TLC ceiling, though the larger capacity gives the cache more absolute headroom before that happens. For gaming, content libraries, and everyday multitasking, the TN470 2TB keeps up with pricier DRAM-equipped rivals, which is a big part of why independent reviewers rated the line well for its price. Buyers doing constant large sustained writes, such as video editors, will still find more consistent behavior on a drive with dedicated DRAM, though most gaming and creative workflows won't notice the difference.

## Endurance, TBW & Warranty

Inland rates the TN470 2TB at 1,200 TBW of total write endurance, double the 1TB model's rating. At a typical 20-50 GB of writes per day, that budget lasts roughly 66 to 164 years before hitting the rated limit, far beyond the drive's realistic service life, so endurance isn't a practical concern for normal use. The MTBF rating is 1,500,000 hours, a statistical reliability figure describing failure rates across a large population of drives rather than a promise for any individual unit.

Warranty coverage on this listing is 6 years, notably generous for a budget-priced drive and matching or beating several brand-name competitors at this capacity.

## Pros and Cons

**Pros:**

- 7,300 MB/s sequential reads on PCIe 4.0
- 1,200 TBW endurance, double the 1TB model
- 6-year manufacturer warranty
- Single-sided design fits PS5 and thin laptops
- Kioxia BiCS6 TLC NAND, not cheaper QLC
**Cons:**

- DRAM-less design relies on Host Memory Buffer
- No included heatsink for sustained desktop loads
- Random IOPS figures not independently confirmed
- Mainly sold through Micro Center's own retail channel


## Verdict

The Inland TN470 2TB suits gamers, content creators, and PS5 owners who want flagship-tier PCIe 4.0 speed, a large game or media library, and a genuinely long 6-year warranty without paying flagship-tier prices. It's a slightly weaker choice for buyers doing constant large sustained writes, where a DRAM-equipped drive holds sequential speed more consistently past the cache limit. Buyers who want a more widely available alternative outside Micro Center's retail channel should look at the WD Black SN770. Overall, the TN470 2TB extends the line's efficient, fast, and inexpensive reputation with properly-scaled endurance for the capacity.

## Frequently Asked Questions

### Is the Inland TN470 2TB good for gaming?

Yes - its 7,300 MB/s rated sequential read cuts load times noticeably versus SATA, and 2 TB is enough room for a large modern game library. Normal gaming use rarely pushes past its SLC write cache, making it a well-reviewed choice for a primary gaming drive at a budget price.

### Is the Inland TN470 2TB compatible with the PS5?

Yes - its 7,300 MB/s rated sequential read comfortably clears Sony's suggested 5,500 MB/s minimum for PS5 expansion storage, and its single-sided M.2 2280 form factor without a tall heatsink fits the console's internal slot without clearance issues. At 2 TB it's also a practical capacity for a large PS5 game library.

### Does the Inland TN470 have a DRAM cache?

No, the TN470 is a DRAM-less design that uses Host Memory Buffer (HMB) to borrow a portion of system RAM for its mapping tables instead of a dedicated DRAM chip. Despite the missing DRAM, independent reviewers found it competitive with pricier DRAM-equipped drives on everyday performance.

### What is the TBW endurance of the Inland TN470 2TB?

Inland rates the 2TB TN470 at 1,200 TBW (terabytes written), backed by a 6-year limited warranty. At a typical 20-50 GB of writes per day, that works out to roughly 66 to 164 years before reaching the rated limit, far longer than most buyers will keep the drive in service.

### Does the Inland TN470 2TB need a heatsink?

It doesn't ship with one, and for laptops, the PS5, or light-to-moderate desktop use it generally doesn't need one thanks to its efficient, single-sided design. Desktop users running sustained heavy write workloads may see a small benefit from adding a motherboard M.2 heatsink, but it isn't required for normal operation.

### How does the Inland TN470 2TB compare to the WD Black SN770?

Both are DRAM-less PCIe 4.0 drives that reach flagship-tier rated speeds, but the TN470 rates higher on paper for sequential reads and carries a longer 6-year warranty, while the WD Black SN770 is more widely available through mainstream retailers beyond Micro Center. For buyers who can find the TN470 in stock, its combination of speed, endurance, and warranty is hard to match.

### Should I buy the Inland TN470 1TB or 2TB?

Both share the same 7,300/6,400 MB/s rated speed and 6-year warranty, so the choice comes down to capacity needs and endurance headroom - the 2TB model doubles TBW to 1,200 alongside doubling storage space. Buyers with a large or growing game and media library get more value from the 2TB, while the 1TB suits smaller budgets or secondary-drive use.
