SanDisk® SSD Plus

[bw123]

I bought the 120GB SSD Plus today for my old laptop.  It was a very easy upgrade, and the machine is a lot faster now.  I did some reading first, and I think this setup is going to last a pretty good while.

I've owned several Sandisk products through the years, from early mp3 player, flash drives and such.  Always good stuff.

I thank you for the cool gadgets!

Dell Inspiron 1012, BIOS A12, 2GB

OS: Debian 8.5 'Jessie' with KDE 4.14 Plasma Netbook.

Linux 3.16.0-4-amd64 #1 SMP Debian (2016-07-02) x86_64 GNU/Linux

The swap is almost never used, KDE runs fine on 2 GB.

The unexpected power losses seem to be from a few episodes where battery fell below 5%

I ran the smart tests just to see if they complete. I'm not sure how to interpret the life curve, but not concerned.

Really nice, dependable drive!

Yes , ssd plus is a cheap and fast upgrade but i recommend that leave minimum 8GB unallocated space on ssd. Since there is no cache in disk , leaving some unallocated space for overprovisioning will increase life of ssd pretty much

Thanks, I did resize the extended partition, and now have about 19G unallocated.  Since then I changed over to gpt partition table. Looks like this now.
