Best SSDs 2026: Ranked by Price Per Terabyte

Crucial P510 holds first at 9.1 and the ranking carries forward. I have spent the last few weeks on price and timing, so today I want to settle the hardware question readers ask me most in this market: is PCIe 5.0 worth paying for, or does a PCIe 4.0 drive do the job?

For a gaming PC or a general desktop, a fast PCIe 4.0 drive or an efficient entry PCIe 5.0 drive covers everything. Game loading depends mostly on random read performance and on how well the game engine streams assets, and the difference between a good Gen4 drive and a flagship Gen5 drive in load times is a second or two in most titles. That is why my top four all score between 8.0 and 9.6 on random I/O while posting 9.0 or better on price per terabyte. The P510 is a DRAM-less PCIe 5.0 design that runs cool, with an 8.8 thermal score, and that makes it an easy fit in a motherboard slot under a hot graphics card.

A flagship Gen5 drive earns its price in one situation: large sustained writes. If you copy multi-hundred-gigabyte video projects, move virtual machine images or cache large AI model files, sustained write after the cache fills is the number you feel. The Crucial T710 scores 9.4 there with 9.4 random I/O, and the Samsung 9100 PRO posts 9.2 and 9.6. Those drives shorten a real workday for the people who need them.

With NAND pricing still elevated, that distinction is worth money. A flagship Gen5 2TB drive costs noticeably more per terabyte than the P510 or the KIOXIA EXCERIA PLUS G4, and for a player that premium buys very little you would ever notice. Spend it on capacity. A 2TB P510 that holds your full library does more for daily use than a faster 1TB drive that forces you to uninstall games.

Crucial P510 holds first at 9.1 and the ranking carries forward. Yesterday I looked at where 1TB and 4TB prices sit. Today I want to give a straight answer on timing, because Amazon has now confirmed Prime Big Deal Days for 6 and 7 October and readers are asking whether to hold their storage budget until then.

My answer for internal NVMe drives is to buy the capacity you need now. NAND output for 2026 is already committed, largely to AI and data centre customers, and consumer drives divide up what is left. A 2TB NVMe that sold for $120 to $150 a year ago now runs $300 to $480 depending on the tier. Contract DRAM pricing rose as much as 89 percent in a single quarter this year, and the same capacity pressure sits behind flash. A deal event redistributes a discount budget across a catalogue. It does not create supply.

So the practical move is to buy once and buy long. Pick the drive that covers your next two or three years of games, projects and backups, install it, and stop watching the trackers. The Crucial P510 sits at the top of my list because it pairs a 9.6 on price per terabyte with traceable NAND and a 9.2 on Taiwan retail availability, which matters when a model number quietly changes revision.

For readers who want the safest possible purchase in this market, the KIOXIA EXCERIA PLUS G4 at 9.0 and the SK hynix Platinum P51 at 8.9 both score 9.8 on NAND sourcing. Both companies make their own flash, so you know exactly what is inside the package, and that certainty is worth real money when every controller and die on the market is being substituted somewhere.

Crucial P510 stays first at 9.1 and the ranking carries forward. The drives on this list had a quiet week, so the useful information is in the price data and what it says about which capacity to buy.

CheapestSSD's September 14 snapshot puts the cheapest 1TB NVMe drive at $156.75, a Kingston NV3, and the Samsung 990 Pro 1TB at $353.99. Both are a couple of dollars lower than a week earlier. I read that as a flat market holding at a high plateau. The same tracker shows 4TB drives giving the best cost per terabyte at roughly $70 to $90 per TB, and Tech Insider reports that a 2TB NVMe drive that cost $120 to $150 a year ago now runs $300 to $480.

The reason it stays this way is supply. All the major NAND makers have said their 2026 production is sold out, mostly to AI and data center buyers, and consumer drives get the remaining wafers.

So my capacity advice gets firmer. If your budget reaches 4TB, that tier delivers the most storage per dollar. If it stops at 2TB, the drives at the top of this list are where I would spend.

Crucial P510 earns first with a 9.6 price per terabyte score and consistent Micron NAND across production runs. KIOXIA EXCERIA PLUS G4 at 9.0 is my laptop and console drive, with a 9.5 thermals score. SK hynix Platinum P51 at 8.9 posts a 9.6 random I/O score and sells for NT$9,199 in Taiwan. For heavy video work, Crucial T710 and T705 lead sustained writes at 9.4 and 9.2.

Crucial P510 stays first at 9.1 and the ranking carries forward. None of the drives I track launched a new revision, got recalled or swapped controllers this week, so every score stands.

The number worth your attention is price. CheapestSSD's tracker logged the cheapest 1TB NVMe drive at $156.77 on September 8, a Kingston NV3, and listed the Samsung 990 Pro 1TB at $357.88 on the same date. That is the market we are buying in, and the trend line on that tracker kept pointing up into September.

The practical advice follows from the math. Cost per terabyte improves as you move up the capacity ladder, so the 2TB drives on this list are where I would spend. Buying 1TB today and upgrading next year means paying the premium twice.

Crucial P510 earns first on a 9.6 price per terabyte score and a Micron NAND and controller pairing that has stayed consistent across production runs. KIOXIA EXCERIA PLUS G4 at 9.0 is the drive I put in laptops and consoles, with a 9.5 thermals score and NAND that KIOXIA manufactures itself. SK hynix Platinum P51 at 8.9 posts a 9.6 random I/O score, and at NT$9,199 in Taiwan it is a strong local buy.

For anyone moving large video files every day, Crucial T710 and T705 hold the best sustained write scores here at 9.4 and 9.2. Both run warm, so budget for a heatsink.

Crucial P510 holds first at 9.1, and this week the commentary belongs to pricing more than to hardware. NAND contract prices rose between ten and fifteen percent through the third quarter. That is a substantial increase, and it is also a marked slowdown from the roughly sixty percent jump recorded in the second quarter. The market is decelerating while remaining far above where it sat a year ago.

What that means in practice: buying storage now costs more than it should, waiting is unlikely to help, and the sensible move is to buy the capacity you need once instead of buying small and upgrading later. Two purchases in this market cost more than one correct purchase.

The P510 earns first on sustained write performance once the cache is exhausted, which is the number that decides how a drive behaves during a large game install or a video import. Peak sequential figures come from short bursts and look identical across a dozen drives. KIOXIA EXCERIA PLUS G4 at 9.0 and SK hynix Platinum P51 at 8.9 both hold their positions on endurance and consistency.

Check your motherboard generation before you spend. A Gen 5 drive in a Gen 4 slot delivers Gen 4 speed at a Gen 5 price.

Storage buyers need to be paying attention to the same supply story that has hit graphics cards. AI data centers are absorbing memory production, and NAND pricing has begun following DRAM upward. If an SSD upgrade is on your list for this year, the case for buying sooner is stronger than it has been in a decade.

The ranking holds. The Crucial P510 2TB stays first at 9.1 because it delivers PCIe 5.0 performance at a price that does not demand you justify it. Most people never saturate PCIe 4.0, so buying Gen 5 makes sense only when the premium is small, and on the P510 it is.

The KIOXIA EXCERIA PLUS G4 at 9.0 is the endurance pick. KIOXIA manufactures its own NAND, and in a market where controller and flash pairings change without notice, that vertical integration means the drive you buy matches the drive that was reviewed.

The SK hynix Platinum P51 at 8.9 is the fastest sustained performer here and the right choice for large sequential workloads like video editing.

Buy 2TB. The price per terabyte at 2TB is the best in the market, and 1TB drives fill faster than anyone expects.

TrendForce now forecasts NAND flash contract prices rising a further ten to fifteen percent quarter over quarter in Q3 2026, on top of increases that already took consumer 1TB drives from roughly forty five dollars in late 2025 to close to ninety dollars. I built this ranking around price per terabyte and spec stability for exactly this reason, and the forecast confirms the ordering.

The Crucial P510 stays first because Micron controls its own NAND supply. When contract prices rise, a drive built on captive fab output holds its retail price better than a drive assembled from purchased flash. That is the whole argument for the nandSource factor, and 2026 has been an extended proof of it.

Kioxia Exceria Plus G4 at 9.0 sits second on the same logic with the added benefit of consistently good sustained write performance under long transfers. If you move large video files, this is the one I would test first.

What I want readers to internalise is that the relief point has moved. Industry consensus put consumer price easing at the end of 2026 earlier this year, and that expectation is now pushed to 2027. Buying advice follows directly from that. If you need a drive in the next twelve months, buying now costs less than waiting, and that is an unusual thing for me to say about storage.

One more note on spec stability. Several vendors have quietly changed the NAND inside drives that kept the same model number. I score specStability heavily because a review of a drive you cannot actually buy is worthless, and the drives at the top of this list have held their configuration.

The Crucial P510 takes first place at 9.1, and the arithmetic is the entire argument. On the Coolpc price list this morning, 6 September 2026, the 2TB P510 sits at NT$9,500. That is NT$4,750 per terabyte for a PCIe 5.0 drive with genuine TLC flash. On the same list, on the same day, the 2TB WD_BLACK SN8100 is NT$20,500, or NT$10,250 per terabyte. One shop, one morning, the same capacity, and a terabyte costs 2.2 times as much depending on which box you pick up. I rank by price per terabyte because in 2026 that is the number that moved, and it moved further than any other spec on the shelf. Here is what pushed it. Phison's chief executive confirmed that TLC 1-terabit NAND contract pricing climbed from $4.80 to $10.70 in six months, that essentially all of 2026 production is already committed, and that the pressure runs through 2027. TrendForce has third-quarter 2026 NAND contract prices rising another 10 to 15 percent quarter on quarter and notes that consumer buyers have reached their affordability limit. AI datacentre demand is taking the wafers, enterprise drives are absorbing close to half of global NAND bit shipments, and consumer parts get what is left. The second thing to understand is that the model number on the box has stopped being a promise. Samsung shipped a 990 in 2026 that reads 7,250 MB/s and writes 6,450 MB/s with 850K random read IOPS, sitting alongside a 990 PRO rated at 7,450 and 6,900 with 1,400K. The 990 launched at $530 for 2TB, which is more than the 990 PRO cost at its own 2022 launch. Buyers who pattern-match on the family name will pay more for less throughput. The precedent goes back further: in 2020 and 2021 Adata shipped the XPG SX8200 Pro with a changed controller and changed NAND under an unchanged model number and unchanged spec sheet, and Tom's Hardware measured a 41 percent drop in file-copy performance on the revised units. So I score every drive on where its NAND actually comes from, and I favour drives sold by the companies that own the fab. Micron sells Crucial, Kioxia sells EXCERIA, Samsung sells Samsung, and YMTC sells ZhiTai. When the fab owner puts its own name on the retail box, the flash inside is traceable and the revision history is public. On buy or wait: buy. Supply relief arrives in 2027, contract prices are still climbing this quarter, and every month you wait costs you roughly the discount you were hoping to find.
