# Inland TN470 1TB: fast, efficient, budget PCIe 4.0 (2026)

The Inland TN470 1TB is a single-sided, DRAM-less PCIe 4.0 NVMe drive that Tom's Hardware rated efficient, fast, and inexpensive, undercutting brand-name flagships on price.

Quick answer: The Inland TN470 1TB suits gamers and PS5 owners who want flagship-tier PCIe 4.0 speed, strong random IOPS, 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, Tom's Hardware's efficient, fast, and inexpensive verdict holds up: the TN470 1TB is one of the stronger price-to-performance picks in its class.

## Performance

Inland rates the TN470 1TB at up to 7,300 MB/s sequential reads and 6,400 MB/s sequential writes over PCIe 4.0 x4, flagship-speed territory for a DRAM-less budget drive. Tom's Hardware's independent testing measured random IOPS around 900,000 for both reads and writes, a strong result that helps explain the review's efficient, fast, and inexpensive verdict.

Like other HMB drives, the TN470 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, a pattern common to nearly every drive in this class. For gaming, OS responsiveness, and everyday multitasking, the TN470 keeps up with - and in random-IOPS terms sometimes beats - pricier DRAM-equipped rivals, which is a big part of why independent reviewers rated it 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.

## Endurance, TBW & Warranty

Inland rates the TN470 1TB at 600 TBW of total write endurance. At a typical 20-50 GB of writes per day, that budget lasts roughly 33 to 82 years before hitting the rated limit, far longer than most buyers will own the drive, 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. Combined with the drive's strong independent review reception, the warranty term is one of the TN470's stronger selling points against similarly-priced rivals.

## Pros and Cons

**Pros:**

- 7,300 MB/s sequential reads on PCIe 4.0
- 6-year manufacturer warranty
- Single-sided design fits PS5 and thin laptops
- Kioxia BiCS6 TLC NAND, not cheaper QLC
- Rated efficient and fast by Tom's Hardware testing
**Cons:**

- DRAM-less design relies on Host Memory Buffer
- No included heatsink for sustained desktop loads
- 600 TBW is modest next to some TLC rivals
- Mainly sold through Micro Center's own retail channel


## Verdict

The Inland TN470 1TB suits gamers and PS5 owners who want flagship-tier PCIe 4.0 speed, strong random IOPS, 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, Tom's Hardware's efficient, fast, and inexpensive verdict holds up: the TN470 1TB is one of the stronger price-to-performance picks in its class.

## Frequently Asked Questions

### Is the Inland TN470 1TB good for gaming?

Yes - Tom's Hardware measured strong random IOPS performance around 900,000 in both directions, and its 7,300 MB/s rated sequential read cuts load times noticeably versus SATA. 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 1TB 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. It's a strong budget option for a PS5 storage upgrade, especially given its unusually long 6-year warranty.

### 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, Tom's Hardware's testing found it competitive with pricier DRAM-equipped drives on random IOPS performance.

### What is the TBW endurance and warranty of the Inland TN470 1TB?

Inland rates the 1TB TN470 at 600 TBW (terabytes written) backed by a 6-year limited warranty, a notably generous coverage term for a budget-priced drive. At a typical 20-50 GB of writes per day, that endurance budget lasts roughly 33 to 82 years before reaching the rated limit, far longer than most buyers will keep the drive in service.

### Does the Inland TN470 1TB 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 single-sided, efficient 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 1TB 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, warranty, and price is hard to match.

### Is the Inland TN470 a reliable SSD brand?

Inland is Micro Center's house storage brand, and the TN470 specifically was reviewed favorably by Tom's Hardware, which called it efficient, fast, and inexpensive. Its use of a Phison controller and Kioxia NAND - the same component tier found in many well-regarded name-brand drives - combined with a 6-year warranty is a reasonable signal of build quality despite being a retailer house brand.
