Storage

Display
SATA 2.5-inch
Feature
Model MZ-77E1T0

A 2.5-inch SATA drive, not NVMe. It is for older laptops with a 2.5-inch bay and no M.2 slot, and it will make an old machine feel faster than a hard disk.

Why we like it

  • Fits older laptops
  • Samsung is a trusted name
  • Large step up from a hard disk

Keep in mind

  • Much slower than NVMe drives
  • Does not fit M.2 slots

Skip it if Your laptop has an M.2 NVMe slot.

Which SSD should you pick?

  • Safe default: WD Blue SN5100.
  • Speed for the money: Lexar NM790.
  • Heavy work and games: WD_Black SN7100.
  • Tighter budget: Crucial P3 Plus.
  • Old laptop with no M.2 slot: Samsung 870 EVO (SATA).

Check your laptop first

Before you order, check what your laptop takes.

  • Slot type. Open the laptop manual or the maker's spec page. Does it have an M.2 slot, or only a 2.5-inch SATA bay?
  • Size. Most laptops take M.2 2280. Some thin ones use 2230, which is a different size.
  • PCIe version. A Gen 4 drive works in a Gen 3 slot, but at Gen 3 speed.
  • Heat. Very fast drives get hot, and thin laptops may slow them down.
  • Cloning. Plan how you will move your data. A cloning tool or a USB enclosure helps.
  • Warranty. Several listings show 5 years. Read the seller's terms.

Quick answers

Frequently asked questions

Will any NVMe SSD fit my laptop?

Not always. Check that your laptop has an M.2 slot, and which length it takes. Most take 2280, but some thin ones use 2230.

Is a Gen 4 SSD worth it for a laptop?

If your laptop supports Gen 4, yes, for large files and fast loading. In a Gen 3 slot it still works, at Gen 3 speed.

What is the difference between NVMe and SATA SSDs?

NVMe drives plug into an M.2 slot and are much faster. SATA SSDs use the older 2.5-inch connection and suit older laptops.

How do I move my data to the new SSD?

Use a cloning tool with a USB enclosure, or do a fresh install and copy your files. Back up first.

Do SSDs need a heatsink?

Most laptops handle it themselves. Some very fast drives run hot, so a thin laptop may throttle them.
