Where to buy UGREEN CM353 Dual M.2 Enclosure in India
Expect to pay roughly ₹4,000-4,400 for the UGREEN CM353 Dual M.2 Enclosure in India right now, depending on offers and seller. I always recommend buying from retailers that give a proper GST invoice - it's what makes your India warranty claim smooth later.
In my years running a PC store, PrimeABGB (Mumbai) and Vedant Computers (Kolkata) have also been consistently reliable for verified stock - compare before buying.
UGREEN CM353 Dual M.2 Enclosure Review India 2026 - Best for Multiple Old SSDs
UGREEN CM353 Dual M.2 Enclosure - India's Best Option for Multiple Old SSDs
The UGREEN CM353 costs ₹3,999–4,299 in India and houses two M.2 drives simultaneously over a single USB 3.2 Gen 2 cable. If you have upgraded your desktop or laptop twice and have two perfectly functional M.2 SSDs sitting idle, this is the most practical way to put both back to work. Sequential reads hit around 900–1,000 MB/s for a single NVMe drive. The aluminium shell handles Indian heat reasonably well for short sessions, but sustained 4K video transfers will cause the enclosure to get warm. Buy it if you have two orphaned M.2 drives and need external storage without buying a new SSD.
What You're Getting
The CM353 is one of the few dual-bay M.2 enclosures available in India under ₹5,000. It accepts two M.2 drives - both NVMe (PCIe) and SATA - in either 2230, 2242, 2260, or 2280 form factors. You can mix types: one NVMe and one SATA in the same enclosure. Each drive shows up as a separate volume on the host machine; there is no RAID function here, which is the right call at this price.
The interface is USB 3.2 Gen 2 (10 Gbps), connected via USB-C. UGREEN includes a USB-C to USB-C cable and a USB-C to USB-A adapter, so it works on most Indian desktop and laptop setups regardless of port availability.
The shell is aluminium. At ₹3,999, the build feels solid - noticeably better than the plastic enclosures at ₹999.
Transfer Speeds and Thermal Reality
With a single NVMe drive installed, the CM353 hits roughly 900–1,000 MB/s sequential read in CrystalDiskMark on Windows. With two NVMe drives both active, total throughput shares the 10 Gbps USB bandwidth, so each drive gets around 500 MB/s under simultaneous load. This is not a limitation of the CM353 specifically - it is a fundamental constraint of USB 3.2 Gen 2 with two drives.
For Indian video editors who are copying dailies or working with footage on one drive while backing up to the other, the speed is more than adequate. For pure sequential transfer of one drive at a time, 900+ MB/s is fast enough to be non-annoying.
Thermal behaviour in Indian conditions is the honest caveat here. The aluminium body does act as a passive heatsink. In a 35–38°C room - common in Indian summers without active AC - the enclosure will get noticeably warm after 15–20 minutes of sustained transfer. I did not see thermal throttling kick in during short burst transfers, but I would not leave it in direct sunlight or in a confined space during a long backup. UGREEN does not include a fan, and adding one is not practical on this form factor.
India Value and Availability
Where to buy: Amazon India (₹3,999–4,199, from UGREEN's official storefront). Flipkart lists it at ₹4,099–4,299. MDComputers sometimes carries UGREEN accessories at comparable pricing but availability is inconsistent - check before relying on it.
The India use case: If you bought a 256 GB NVMe SSD with your first build, upgraded to 512 GB a year later, and then replaced that with a 1 TB drive recently, you likely have two perfectly functional M.2 SSDs doing nothing. The CM353 lets you use both simultaneously as external drives. At ₹4,000, that is cheaper than buying two separate enclosures (each at ₹1,500–2,000) and uses a single USB port instead of two.
USB 3.2 Gen 2 port availability: Most Indian desktop motherboards from 2020 onwards have at least one USB 3.2 Gen 2 Type-C or Type-A port. Laptops are less consistent - check your spec sheet. If your machine only has USB 3.0 (5 Gbps) ports, the CM353 will still work but you will cap out at around 400–450 MB/s total, which removes some of its speed advantage.
GST and warranty: Prices include 18% GST. UGREEN's India warranty is 18 months for this product, handled through their official Amazon India storefront. For GST invoices for business purchase, use Amazon Business.
Who Should Buy This
Buy the CM353 if you have two M.2 drives from previous builds and want to put both to use without buying separate enclosures. Indian video editors working with 1080p or 4K footage will find the speed adequate for most on-location backup tasks.
Skip it if you only have one M.2 drive to repurpose - a single-bay enclosure at ₹1,500–2,500 is better value. Also skip it if you need to run sustained 4K video reads in a hot room without climate control; the thermal performance under those conditions is marginal enough to cause concern.
Questions
Yes. The CM353 supports both PCIe (NVMe) and SATA M.2 drives in the same enclosure, mixed or matched. Each drive is detected independently. There is no RAID - they show up as two separate drives on your system.
Yes. UGREEN includes a USB-C to USB-A adapter in the India box. You will be limited to the maximum speed your USB-A port supports - 5 Gbps on USB 3.0 or 10 Gbps on USB 3.2 Gen 2. The enclosure itself is not the bottleneck.
For short sessions - copying cards, running a quick backup - yes. For sustained, hours-long transfers in a 38°C room, the enclosure gets warm enough that I would keep an eye on it. It did not throttle in my testing, but I would not stress it without some airflow around it.
