What customers say about "Key Specs"

SanDisk Ultra II SSD

Unless you are some super gamer, ultra power user with some crazy fast and expensive computer, this hard drive will be quite sufficient for you in terms of speed.
Overall its an amazing SSD, really fast and great read and write speeds
I put a 480gb version in my 5 year old Lenovo T420 with Windows 10 & 8gb of memory and the thing is amazingly fast!
Granted, I knew that this Drive I was purchasing was by far not the best but by far not the worse!
Great ssd. Has been reliable so far. I have an evo 850 on another desktop and I cannot tell the speed difference of anyone cares.

SanDisk Extreme PRO SSD 960 GB Sata III 2.5 Inch Internal up to 550 MB/s

So I have the need for speed when I spend a few hours editing these files and this...is the drive used and it can't be too fast.
After installing Windows 10 on this hard drive, I was blown away by the speed.
It's done a great job so far handling all of these tasks with speed.
I had no idea just how much faster my computer would be with this hard drive.
When the drive works as advertised, the speed is still great. Will not choose Sandisk again in the future for an SSD Solution.

What customers say about "Features"

SanDisk Ultra II SSD

This SSD was priced great when I bought it... It features the latest type of memory which is more reliable than the previous type for SSDs. I
The Ultra II is a bit newer SSD with designed mid-level performance (for a SSD) and economy pricing.
More importantly this drive will start to degrade data when it nears it's low design life and if kept in a hot area, will degrade, not good.
Using less RAM, fan is much quieter, boot time is under 20 seconds, loading programs and opening files are instantaneous. No spin wheels for me anymore.
My PC only supports SATA3, and this drive is backwards compatible with the older SATA. Highly recommend a SSD to bring life to an older PC.

And some extra features and specification it offers over cheaper alternatives may prove its value in long term.
I'm a consumer who is not into gaming. I see that one of the promoted features of this SSD is improved gaming speed and performance.
The 10 year warranty was an amazing feature!
SSD have no moving parts, thus very quiet and resist damage from vibration. This makes them ideal for laptops.
I think Apple tests their OS with flash drives, so as they increase the Input/Output read write counts when adding features/security protections, they don't notice the issues caused in systems with using hard disks.
