- Intelligent Block Management & Wear Leveling automatically distributes data evenly across the entire SSD.
- Intelligent Read Disturb Management spreads the active read/write across the flash components eliminating data corruption caused by constant use.
- Intelligent "Recycling" for advanced free space management gradually re-writes data across the SSD over time to ensure data never gets corrupted.
- RAISE™ (Redundant Array of Independent Silicon Elements) protects the data on your drive similar to having a RAID setup.
- Best-in-Class ECC Protection for longest data retention and drive life.
This internal 2.5" SATA SSD uses the latest SandForce 2281 Processor and DuraClass™ technology to deliver the highest transfer speed, endurance, and performance available today.

An easy swap for my dead Macbook Pro 17" HD
November 26th 2025 Verified user
A good price and delivered promptly. A an easy replacement for my original but dead mechanical HD. I hope it will last a long time. Maybe I should have bought a larger GB version, but this will do the job for now. Thank you.

Thanks, Great performance boost

Working great in my old Macbook 2.2 core 2 duo which was crawling with an 12 year old fragmented 160GB hard disk.
Cloned the new drive with Mac disk utilities and a housing. Easy to fit with a small philips and small Torx screwdriver following online guides. Massive speed boost in performance, perhaps 3-400% quicker now.

Good but not good for iMac
October 10th 2016 Verified user
So far the performance is good. Only problem is it's what's recommended for an iMac. Removing a 3.5 and replacing it with a 2.5 is an issue when I does not fit or mount inside. You will have to fabricate a mount to install it. This does effect the airflow a bit and can cause the fans to run harder.
