Heres another thing AI has done for me
I gave it 2 screenshots from Ali Express
We need to compare the two deals for 4TB NVMe SSDs from AliExpress. The user provided two image screenshots: one for MOVESPEED 7450MB/s SSD and one for Fanxiang S880R 7450MB/s SSD. Both appear to be PCIe 4.0 x4, 4TB, with similar speeds. They are for upgrading a Dell Precision 3520 laptop, which likely only supports PCIe 3.0, but backward compatibility is fine. We need to compare price, brand reputation, seller, and any other relevant details. Also note the userās laptop compatibility: M.2 2280 NVMe PCIe 3.0, so a Gen4 drive will work at Gen3 speeds.
Letās extract details from images:
MOVESPEED:
- Brand: MOVESPEED
- Model: 7450MB/s SSD NVMe M.2 2280 4TB (up to 7450MB/s)
- Sold by: MOVESPEED Official Store (Trader)
- Rating: 4.8 (3865 reviews), 10,000+ sold
- Price: £442.71 (saving £976.84, includes VAT)
- Capacity options: 1TB,2TB,4TB shown
- Features: PCIe 4.0x4, for PS5 Laptop PC
Fanxiang:
- Brand: Fanxiang S880R
- Speed: 7450MB/s, PCIe Gen4x4
- Includes: āWith Heatlinkā (maybe heatsink)
- Rating: 4.8 (41 reviews), 177 sold
- Price: £366.40 (save £432.62, includes VAT)
- Extra 2% off with coins
- Delivery: Apr 07-11 (free shipping)
- Seller: Fanxiang (likely official store?)
- Service commitment: free returns within 90 days, etc.
Clearly Fanxiang is cheaper (£366 vs £442). It has fewer reviews but still good rating. MOVESPEED has many more reviews and sales. Both are reputable Chinese SSD brands; Fanxiang is known for budget SSDs, MOVESPEED is also a budget brand but with more established presence.
Also note: The userās Dell Precision 3520 likely has PCIe 3.0, so the Gen4 drive will be limited to Gen3 speeds (~3500 MB/s). But thatās fine.
We need to provide a comparison highlighting the price difference, brand reliability, and any potential considerations (heatsink? Fanxiang includes āHeatlinkā, may be useful if the laptop has space). The Fanxiang also mentions āExtra 2% off with coinsā, which could lower price further.
Letās craft a concise comparison and recommendation.
We should also mention that for a laptop, especially a Dell Precision 3520, check physical clearance for any heatsink; some M.2 drives with large heatsinks may not fit. The Fanxiang mentions āWith Heatlinkā, but it might be a thin copper sticker or a small heatsink; if itās a tall heatsink, it might not fit in a laptop. The MOVESPEED likely doesnāt include a heatsink (typical for laptops). So thatās a factor.
Also note the MOVESPEED official store vs Fanxiangās seller; both seem official.
Given the price difference, Fanxiang is significantly cheaper. With the extra 2% coins, it could be ~Ā£359. Both offer similar specs. For a laptop upgrade, Iād lean toward the cheaper option unless there are reliability concerns. But MOVESPEED has many more positive reviews.
Weāll present a table and then a recommendation.
Letās produce final answer.

Key Considerations for Your Dell Precision 3520
- Physical compatibility ā The Precision 3520 takes a M.2 2280 PCIe 3.0 NVMe drive. Both are M.2 2280 and PCIe 4.0 (backward compatible), so theyāll work, but will run at PCIe 3.0 speeds (~3500 MB/s).
- Heatsink clearance ā The Fanxiang includes a āHeatlinkā. If thatās a tall heatsink, it may not fit inside the laptop chassis. The MOVESPEED appears to be a bare drive (no heatsink), which is safer for a laptop.
- Price difference ā Fanxiang is Ā£76 cheaper , and with the extra 2% coins discount it becomes even more attractive.
- Reliability ā MOVESPEED has far more sales and reviews, suggesting a longer track record. Fanxiang is also a known budget brand, but with fewer reviews.
Recommendation
- If you want the cheapest option and are confident the āHeatlinkā is only a thin sticker (or you can remove it), Fanxiang saves you money.
- If you prefer a triedāandātested bare drive that fits without any clearance worry, MOVESPEED is the safer choice, albeit more expensive.
Before buying , doubleācheck the sellerās listing to confirm:
- The Fanxiang driveās physical height (with heatsink).
- That both are NVMe (not SATA) and 4ālane .
- The return policy and warranty details.
If you have room in the budget, the MOVESPEEDās high review count and established store reputation give extra peace of mind for a critical internal drive.
Iāll look for other deals on 4TB NVMe sticks and add them to the comparison table.
Bottom line - its doing work for me that I could do myself but much much faster - and also raises various issues that I should check for before spending money.
But Iām with you on this AI has raised the cost of memory generally.
