What customers say about "Key Specs"
SanDisk Extreme PRO 500GB M.2 NVMe 3D Internal Solid State Drive
  • It is great for users wanting to transfer large files. Great speeds.
  • Incredibly fast drive, fast installation and easy installation.
  • Speed and quality have led me to buy this product.
  • Strong sequential performance for creatives.
  • Impressive first-gen design. Controller architecture is amazing.
SanDisk Ultra II 1TB SATA III SSD
  • The speed and quietness of this drive compared to a typical HDD are almost eerie for ordinary tasks on a laptop like booting Windows, loading a large document into MS Word, etc.
  • Great value SSD! Good enough to keep up with full DCI 4K 60FPS recordings in ProRes and DNxHR in my Atomos Ninja Inferno!
  • Easy to fit, I reinstalled Windows on this new drive. No problems, the PC is noticeably faster, and I have a bunch more space. Very happy with this!
  • The laptop still runs warm, so for me, can't comment on any difference between heat generated. I also can't comment on battery life differential as I'm generally plugged in.
  • The drive was great while it worked. It just disappeared from my 2010 iMac without any warning. The computer went to sleep mode and the drive failed during this time.

What customers say about "Features"
SanDisk Extreme PRO 500GB M.2 NVMe 3D Internal Solid State Drive
  • It installed easily and I was able to clone my Windows 10 system from my SATA SSD in around 25 minutes.
  • Ideal for boosting your computer. This SSD works great on a Macbook Retina 2015 with a small adapter.
  • Fast, easy to install. No issues.
  • Great product. Fast and reliable.
  • Small and handy, quickly installed.
SanDisk Ultra II 1TB SATA III SSD
  • Fast. Great storage. Bought the SSD mounting bracket to hold it. Absolutely no complaints.
  • Cheap and faster than budget ssd's. On par with top ssd's (excluding nvme) when copying large files.
  • Was an excellent purchase. With this the Macbook Pro is now faster and battery lasts longer!
  • A great drive at a great price! Transformed my iMac into a screaming fast mother that I can now run Mavericks and Sierra on it on 2 partitions. Just what my iMac needed!
  • Great 500GB drive. Sadly, it appears to be mislabeled as 1TB. Everything works fine until I hit the 500GB limit and then the drive refuses to write. Keep under 500GB, and it works fine.
