Storage is the one shelf where the headline specification is a plain number on every listing, so comparing two shops is arithmetic rather than opinion. We read both on the same morning and divided every price by the capacity in its own title.
Croma's median gigabyte came out at Rs. 12.88 and Amazon's at Rs. 19.43 — but on SSDs the two are one paisa apart, and a matched SanDisk pen drive was a rupee apart. The gap is what each shop stocks: 5TB drives at one, 8GB cards at the other.
📅 Both shelves read 14 September 2026
Amazon Rs. 19.43 a GB, Croma Rs. 12.88 a GB
Cheapest gigabyte in either shop: Rs. 2.88, on a 5TB drive
📅 Update log:
14 Sep 2026 — first published. 67 listings read from amazon.in search results across six storage queries and 61 from croma.com across four, both on 14 September 2026, logged out, in India. Per-gigabyte figures are our arithmetic on the capacity stated in each listing's own title, with 1TB taken as 1,024 GB; listings stating no capacity are excluded. Both shops re-price this aisle continuously, so we re-read it and log what has changed here.
The only number that compares two storage shelves is the price of a gigabyte
Storage is unusual on the Indian internet: the headline specification is a plain number, printed in the title, on every listing. So on 14 September 2026 we read 67 listings on amazon.in and 61 on croma.com and divided every one of them by the capacity it claims. Sixty-three Amazon listings and sixty Croma listings state one.
The medians come out a long way apart. Amazon: Rs. 19.43 per gigabyte. Croma: Rs. 12.88. That gap is almost entirely about what each shop stocks rather than what it charges. Croma's hard-drive shelf goes up to 5TB and Amazon's read topped out at 2TB; Amazon's memory-card shelf is full of 8GB, 16GB and 32GB tiles that Croma does not sell at all, and small cards are the most expensive storage there is per gigabyte.
Strip the size difference out and the two shops are startlingly close. On solid state — where both stock the same capacities from the same brands — the medians are Rs. 17.08 per GB at Amazon and Rs. 17.09 at Croma. One paisa, across thirty listings.
Format by format, and where each shop actually wins
Read by format, the two shelves swap the lead twice. Croma is cheaper per gigabyte on hard drives and on memory cards; Amazon is cheaper on pen drives; on SSDs they are indistinguishable.
The hard-drive gap is the big one and it is a stocking decision. Croma's eighteen hard-drive listings include four 5TB drives and five 4TB drives, and the cheapest gigabyte in either read is a WD My Passport 5TB at Rs. 14,749, which is Rs. 2.88 per GB. Nothing in the Amazon read goes above 2TB, so its cheapest rate is Rs. 4.05 on an unbranded 1TB drive — 41 percent dearer per gigabyte than Croma's biggest.
The memory-card gap runs the same way for the opposite reason. Croma's nine cards are all 32GB and up and mostly SanDisk Extreme; Amazon's twenty-two include 8GB cards at Rs. 387 and Rs. 1,499. Those tiny tiles are what pull Amazon's card median to Rs. 29.56 against Croma's Rs. 14.83, and they are a trap on either shelf.
| Format | Amazon | Croma | Cheaper per GB |
|---|
| External hard drives | 9 listings, Rs. 5.21/GB | 18 listings, Rs. 4.21/GB | Croma, because it stocks 4TB and 5TB |
| Internal and portable SSDs | 18 listings, Rs. 17.08/GB | 12 listings, Rs. 17.09/GB | Neither — one paisa apart |
| Pen drives | 11 listings, Rs. 14.75/GB | 21 listings, Rs. 16.63/GB | Amazon, by Rs. 1.88 a gigabyte |
| Memory cards | 22 listings, Rs. 29.56/GB | 9 listings, Rs. 14.83/GB | Croma, because Amazon stocks tiny cards |
| Everything with a stated capacity | 63 listings, Rs. 19.43/GB | 60 listings, Rs. 12.88/GB | Croma on the median, Amazon on the floor price |
The same product, one shop to the other
Comparing medians is only half the job, because the two shops stock different catalogues. So we looked for models that appear on both, and there are fewer than you would expect: 35 of Croma's 61 listings are SanDisk, and its pen-drive shelf is almost entirely one brand.
Where a genuine match exists the prices are close and Croma is usually the cheaper of the two. A SanDisk Ultra 128GB USB 3.0 pen drive is Rs. 1,600 on Amazon and Rs. 1,599 at Croma — a rupee. A SanDisk Extreme 1TB USB-C portable SSD is Rs. 19,999 on Amazon and Rs. 18,429 on the cheapest of Croma's three listings for it, a Rs. 1,570 gap.
Two pairs in the table below are not like-for-like and are marked as such. The HP pen drives are different sub-models (819w against 818w) and the SanDisk Extreme cards are different ranges (Extreme GO against Extreme). We have left them in because they show how easily a comparison goes wrong on this aisle: two products with almost the same name can be Rs. 2,170 apart for reasons that have nothing to do with which shop you are in.
| Product | Amazon | Croma | Gap |
|---|
| SanDisk Ultra 128GB USB 3.0 pen drive | Rs. 1,600 | Rs. 1,599 | Re. 1 |
| SanDisk Extreme 1TB USB-C portable SSD | Rs. 19,999 | Rs. 18,429 | Rs. 1,570 to Croma |
| HP 128GB USB 3.2 pen drive (819w / 818w) | Rs. 1,899 | Rs. 1,044 | Rs. 855 to Croma, different sub-model |
| SanDisk Extreme microSDXC 128GB | Rs. 3,669 (Extreme GO) | Rs. 1,499 (Extreme) | Different cards, not a like-for-like |
Where the big capacities are, and why they are the cheap ones
Every rung of this ladder is the same rule: the bigger the drive, the less each gigabyte costs. It holds without exception across both reads and all four formats, and it is the single most useful thing on this page.
The practical version: Rs. 14,749 buys 5TB at Croma; Rs. 14,499 buys 1TB on Amazon. Those are two purchases at almost identical money, five times apart on capacity, because one is a spinning drive at the top of its range and the other is a solid-state drive at the bottom of its. If you need speed, the SSD is the right buy and the arithmetic is irrelevant; if you need somewhere to keep photographs, it is the whole story.
| Drive | Per GB | Shop |
|---|
| WD My Passport 5TB, Rs. 14,749 | Rs. 2.88 per GB | Croma |
| WD My Passport 4TB, Rs. 13,149 | Rs. 3.21 per GB | Croma |
| Seagate One Touch 5TB, Rs. 19,849 | Rs. 3.88 per GB | Croma |
| Toshiba Canvio Ready 2TB, Rs. 8,649 | Rs. 4.22 per GB | Croma |
| Unbranded 1TB portable HDD, Rs. 4,152 | Rs. 4.05 per GB | Amazon |
| MAYUMI 1TB HDD, Rs. 4,950 | Rs. 4.83 per GB | Amazon |
| Toshiba Canvio Ready 1TB, Rs. 6,889 | Rs. 6.73 per GB | Croma |
| UnionSine 1TB HDD, Rs. 7,599 | Rs. 7.42 per GB | Amazon |
One shop, one product, several prices
Neither shelf holds one price for one product. At Croma the SanDisk Extreme 1TB portable SSD appears three times at Rs. 18,429 and Rs. 19,999, and the 2TB version three times between Rs. 28,649 and Rs. 33,999 — an 18.7 percent spread on the same drive, in the same shop, on the same afternoon. Three Seagate One Touch 5TB listings ran Rs. 19,849 to Rs. 20,649.
Amazon does it differently: there, three separate 1TB drives all sold at exactly Rs. 14,499 — an EVM NVMe, a Crucial X9 portable and an Amazon Basics SATA — each printing a different MRP above it (Rs. 18,999, Rs. 18,000 and Rs. 18,699). Same price, three list prices, three badges.
The habit that follows from both is the same one. Search the product name, scroll past the first result, and check whether the shop is listing it more than once.
| Listing | Cheapest | Dearest | Spread |
|---|
| SanDisk Extreme 1TB portable SSD at Croma | Rs. 18,429 | Rs. 19,999 | 3 listings, 8.5% apart |
| SanDisk Extreme 2TB portable SSD at Croma | Rs. 28,649 | Rs. 33,999 | 3 listings, 18.7% apart |
| Seagate One Touch 5TB at Croma | Rs. 19,849 | Rs. 20,649 | 3 listings, Rs. 800 apart |
| 1TB NVMe/SATA SSDs on Amazon | Rs. 14,499 | Rs. 14,499 | 3 different drives at one price, 3 different MRPs |
The badges, and the evidence behind them
The two shops print list prices very differently at the extremes and almost identically in the middle. Median badge: 37 percent on Amazon, 34 percent at Croma. Listings printing an MRP three times the selling price or more: four of 67 on Amazon, four of 61 at Croma.
The extremes are where they part. Amazon's deepest is an HP 128GB pen drive at Rs. 1,243 against a Rs. 5,999 MRP, a 4.8x multiple. Croma's deepest is a SanDisk iXpand 64GB pen drive at Rs. 434 against a Rs. 6,000 MRP — 13.8x, the largest list-price multiple we have seen on a storage listing anywhere. Its E62 Creator 2TB SSD prints Rs. 1,50,500 against Rs. 40,999.
The evidence gap runs the other way and it is wide. Amazon publishes a star average and a rating count on 66 of its 67 listings, several of them in five figures — 85,145 on one pen drive, 81,966 on one SSD. Croma published a star average on 19 of 61 and a rating count on none at all. A '5.0' with no number behind it, which is what three of Croma's drives show, tells you nothing about how many people that represents.
How to buy storage across both shops
- Divide by the capacity before anything else. Across both reads the rate ran from Rs. 2.88 to Rs. 187.38 a gigabyte. No other number on either shelf separates a good buy from a bad one that cleanly.
- Go to Croma for big spinning drives. It stocks 4TB and 5TB where the Amazon read stopped at 2TB, and those are the cheapest gigabytes in either shop — Rs. 2.88 on a 5TB against Rs. 4.05 on Amazon's cheapest 1TB.
- Never buy a small memory card if the device takes a larger one. Amazon's card median is Rs. 29.56 per GB against Croma's Rs. 14.83, and the whole difference is 8GB, 16GB and 32GB tiles. An 8GB SD card at Rs. 1,499 on Amazon costs the same as a 128GB pen drive on the same page.
- On SSDs, buy wherever is convenient. The medians were Rs. 17.08 and Rs. 17.09 per gigabyte. Check the specific model rather than the shop — Croma's cheapest SanDisk Extreme 1TB listing undercut Amazon by Rs. 1,570, and its dearest matched it exactly.
- Treat a Croma star with no rating count carefully. Croma showed a number on 19 of 61 listings and never said how many people it came from; Amazon showed both on 66 of 67.
How we read both shelves
The method, in full
Sixty-seven listings were read from amazon.in search results on 14 September 2026 as a logged-out visitor in India across six queries (ssd 1tb internal, external hard disk 1tb, pendrive 128gb, memory card 128gb, portable ssd, sd card camera), with sponsored placements dropped and duplicate ASINs collapsed. Sixty-one listings were read from croma.com the same day across four queries (pen drive, memory card, solid state drive, hard disk).
Every per-gigabyte figure on this page is our own arithmetic: the displayed selling price divided by the capacity stated in the listing's own title, with 1TB taken as 1,024 GB. Four Amazon listings and one Croma listing state no capacity and are excluded from every rate, median and range. Formatted capacity is always lower than the printed figure, equally for every product here, so the comparison holds even though the absolute number is generous. Format groupings (hard drive, SSD, pen drive, memory card) are ours, read from the listing titles.
Prices are the shelf prices each site displayed to a logged-out visitor. Delivery charges, store pickup, exchange offers, bank-card discounts, EMI terms and coupon codes are not visible in listing data and are not priced into any comparison here; any of them can move the final number in either direction.
The short version
Croma has the cheaper median gigabyte (Rs. 12.88 against Rs. 19.43) because it stocks 4TB and 5TB hard drives and does not stock tiny memory cards. Amazon has far better evidence: a rating count on 66 of 67 listings against none at all at Croma.
On matched models the two are close — a SanDisk Ultra 128GB pen drive was Rs. 1,600 and Rs. 1,599 — and on SSDs the per-gigabyte medians are one paisa apart. Buy the biggest capacity your device takes, wherever you buy it.
Frequently Asked Questions
Is storage cheaper on Amazon or at Croma?
On this read of 14 September 2026, Croma had the cheaper median gigabyte — Rs. 12.88 against Rs. 19.43 across 60 and 63 capacity-stating listings — but that is mostly a difference in what each shop stocks rather than in what it charges for the same thing. Croma sells 4TB and 5TB hard drives, which are the cheapest gigabytes anywhere; Amazon sells 8GB and 16GB memory cards, which are the dearest. Where a model appears on both, the prices are close: a SanDisk Ultra 128GB pen drive was Rs. 1,600 on Amazon and Rs. 1,599 at Croma.
What is the cheapest way to buy a terabyte of storage?
A spinning external hard drive, in the biggest size you can use. The cheapest rate in either read was a WD My Passport 5TB at Croma, Rs. 14,749, which works out at Rs. 2.88 per gigabyte. For comparison, Rs. 14,499 on Amazon that day bought a 1TB SSD — almost the same money for a fifth of the capacity. That is not a bad deal, it is a different product: solid state is faster and has no moving parts. But if the job is storing photographs or backups, the big hard drive is roughly five times more storage for the money.
Why does Croma show star ratings with no number of reviews?
We can only report what the listings display. On 14 September 2026, 19 of Croma's 61 storage listings showed a star average and none of the 61 showed a rating count. Three showed '5.0' with nothing behind it. Amazon, by contrast, showed both figures on 66 of its 67 listings, including samples of 85,145 and 81,966. A star average without a count cannot be weighed — a 5.0 from two buyers and a 4.3 from 62,147 look similar on a tile and mean completely different things.
Are the big discount badges on storage real?
They are real list prices; whether they represent a saving is a different question, and this page does not treat them as one. Both shelves are moderate in the middle — median badges of 37 percent on Amazon and 34 percent at Croma, with only four listings each printing an MRP three times the price or more. The extremes are something else: Croma listed a SanDisk iXpand 64GB pen drive at Rs. 434 against a Rs. 6,000 MRP, a 13.8x multiple, and a 2TB SSD at Rs. 40,999 against Rs. 1,50,500. Read those as the list price a seller chose to print, not as money saved.
Should I buy a 128GB memory card or a 128GB pen drive?
For the same stated capacity they cost about the same at the cheap end and the card costs much more at the top. On Amazon that day a SanDisk Ultra 128GB pen drive was Rs. 1,600 (Rs. 12.50 per GB) and the same brand's 128GB microSDXC card Rs. 2,499 (Rs. 19.52 per GB). At Croma a SanDisk Ultra 128GB pen drive was Rs. 1,599 and a SanDisk Extreme 128GB microSDXC Rs. 1,499. The real decision is what the device takes: a phone or camera needs the card, a laptop takes the stick. What both shelves agree on is that the smallest cards are the worst value — an 8GB SD card on Amazon cost Rs. 187.38 per gigabyte.
Prices & codes last verified: 14 September 2026
Every selling price, maximum retail price, discount percentage, star rating and product title on this page was read on 14 September 2026 — from amazon.in search results across six queries and from croma.com across four — as served to a logged-out visitor in India, with nothing purchased and no account used. Sponsored placements were dropped and duplicate listings collapsed on Amazon. The per-gigabyte rates, the format medians, the MRP multiples and every range, median and percentage gap quoted here are our own arithmetic on those displayed numbers and on the capacity each seller states in its own listing title, with one terabyte taken as 1,024 gigabytes. Stated capacity is a seller claim; the formatted capacity a device presents is always lower, for every product on both shelves, and nothing here was formatted, benchmarked, opened or measured. Read and write speeds, interface generations, speed classes, drop and water ratings and warranty lengths are the sellers' own listing claims and were not verified. Maximum retail prices are quoted because both sites display them; a large gap between an MRP and a selling price reflects the list price a seller chose to print, is not treated here as evidence of a saving, and no wrongdoing by Amazon, by Croma, by SanDisk, Western Digital, Seagate, Toshiba, Lexar, HP, KIOXIA, Crucial or by any seller is alleged or implied. Where either shop listed what appears to be the same product at several prices we report the prices we read and do not speculate about why they differ; listings that share a name are not necessarily identical in seller, sub-model, packaging, warranty or fulfilment, and two product names that differ only slightly can be different products, which is why the matched-model table marks the pairs that are not like-for-like. Comparisons between the two shops compare these two samples on one day and are not a census of either catalogue; a different query, filter, pincode, seller or day returns a different set, and prices at both can change within hours. Delivery charges, store pickup, exchange offers, bank-card discounts, EMI terms, protection plans and coupon codes are not visible in listing data, are not priced into any figure here, and can move your final cost in either direction; the price shown at your checkout prevails over anything on this page. Nothing here tests endurance, data retention, failure rates, after-sales service or whether any device reports a capacity it does not have. Zoutons may earn a commission if you buy through links on this page; it does not change what you pay.
