Which laptops does this fit?
Any laptop with a 2.5" SATA bay — most pre-2018 business laptops, all desktop towers, and many modern gaming laptops that have both an M.2 slot and a 2.5" bay. We've installed it in machines such as Lenovo ThinkPad T480, ThinkPad T490, ThinkPad X1 Carbon Gen 6 and Legion 5. If you're not sure, message us on WhatsApp 0314 4000131 with your laptop model.

What changes after the upgrade
Switching a mechanical HDD to a SATA SSD is the single biggest performance jump you can make to an older laptop. Typical changes:
- Windows boot from cold: 60-90 seconds down to 10-15 seconds.
- Chrome with 15 tabs: stops feeling laggy.
- Office, Photoshop, AutoCAD launch in 2-4 seconds instead of 20-40.
- Battery life improves by 15-25% because the SSD draws less power than a spinning disk.
- Laptop fan noise drops because the SSD doesn't generate heat or vibration.
- You can drop the laptop in a bag with the lid still open and not worry about head crashes.
Why we still recommend SATA SSDs in 2026
NVMe drives are faster on paper, but the difference in everyday use between a SATA SSD and a Gen3 NVMe is small — both feel instant for Windows boot, app launch, and file copy. If your laptop's BIOS doesn't support NVMe (a lot of pre-2017 machines fall into this category), SATA is your only path forward, and the real-world impact of moving from spinning rust to silicon is dramatic.
Installation
Open the bottom cover (most laptops use one or two screws over the storage bay), pull the HDD bracket out, slide the new SSD in, and screw it back. Use Macrium Reflect Free to clone your old disk before installing — the new SSD will be a perfect copy of the old one but dramatically faster. We offer Rs. 1,500 install + clone at the shop, free for purchases above Rs. 20,000. See laptop parts catalogue for matched upgrades.

Frequently asked questions
Will this SSD fit my old Dell Latitude 7490 or HP EliteBook 840 G3?
Yes — both laptops have a 2.5" 7 mm SATA bay. You can keep an existing M.2 NVMe drive in place and use this SSD as secondary storage, or replace the original HDD entirely.
SATA SSD vs NVMe — which should I buy?
If your laptop has an empty M.2 NVMe slot, NVMe is 4-7x faster. If it has only a 2.5" bay (most pre-2018 machines), SATA SSD is your only path and still 5-10x faster than the original HDD.
Does it come with a SATA cable or bracket?
For laptop installs, no cable is needed — the SSD plugs directly into the bay. For desktop installs, you supply a SATA data cable and a 2.5" to 3.5" bracket (we sell both for under Rs. 500 each).
Is this a brand-new sealed drive?
Yes — sealed retail box with original warranty card. We check SMART status before shipment to confirm zero power-on hours.
How long does this SSD last?
Rated for 400 TBW. For typical home use (50 GB writes per month), that's 30+ years of life. The 5-year manufacturer warranty covers any premature failure.
