It really doesn't get any more no-frills than this drive. There's no bracket, no mini CD, no cloning software... you really just get a drive and a couple minimal pieces of documentation. All of that makes sense, since this is really one of the least expensive, large SSDs available. Like most drives of this size, this device uses TLC flash. TLC is the absolute worst, in terms of durability, but it's cheap to produce. It's not published on the Amazon product page, but the durability of the 2TB device is 500TBW.
Assuming the durability rating is correct, the drive should last me about 18 months (which is good enough at this price). You can download a SanDisk utility (screenshot attached to this review) to check the vitals of the device, which takes the guesswork out of estimating the remaining disk life.
On the performance front, the drive is fine. It's far faster than a magnetic drive, but it's pretty slow for an SSD. Expect 85-90% of the performance of a top-flight SATA SSD (you really should be using NVMe if you want speed). However, if you want an inexpensive bulk-storage SSD, you could do much worse.
The laptops were a different story. Turns out the Acronis cloning software will only work if you have a WD or Sandisk drive as the source boot drive for the cloning. They wanted a $30 software upgrade per system to buy version that would work with non-WD/SanDisk drives. Instead of that I used a free version of TODO cloning software. You will need to Google for it. I can't post the link per Amazon rules.
The cloning process takes a long time if your drive has ~300 GB of usage. Mine took about 6-7 hours for the cloning process. The second laptop took about 1 hour to clone. It had about 50 GB of data one it. Once the laptop drives were cloned it was just a matter of removing the old hard drives and installing the new SSD drives. The Dell 1564 was easy to swap in the drive. The second laptop a Dell 1570 was a nightmare to do the swap. It entails taking a lot of the laptop apart to get to the hard drive. Not a task for the timid. Downloaded the service manual for the 1570 which details all the disassembly steps. You will need to Google for it. I can't post the link per Amazon rules.
All three of the systems run amazingly faster now.
I decided to try this out to see how it'll work out. Once I received, I cloned the disk to this SSD, took about 4 hours for 350GB of data plus additional partitions. Popped this baby in the laptop and bootup time was 10 seconds. That was fast, and the login to launching firefox/chrome took an extra second. Shutdown is astoundingly fast as well.
I've always been impressed with SanDisk SD cards, as I use it for my Canon cameras as well, but the SSD for my laptop, it made it 100 times better.
