Inexpensive but relatively slow
Drive came OEM installed on a Dell Inspiron 15 5559 from Staples. It's faster than a standard hard drive, but when I replaced it with a Samsung EVO 250GB drive and optimized it using Samsung Magician software, it tested out several times faster than this SanDisk drive. Understandable, since the Samsung EVO 128GB is twice the price. Sometimes you really do get what you pay for. I've attached photos of the Crystal Disk 5 comparative speed tests.

5.0 out of 5 stars I can highly recommend this SSD
Reviewed in the United States on June 28, 2016
Verified Purchase
I installed this on my personal desktop PC as the primary boot drive and it really makes a BIG difference on boot time, application startup times and greatly speeds up any read/write functions. My PC is one that I built a few years ago and is (or was) fairly beefy with 12 gigs of RAM, an AMD quad core 3.3ghz CPU and around 3TB of hard-drive space. I was using a 1.5TB 7200rpm drive as the boot drive which I thought booted up fairly quick. When I installed this new 128GB Z400S SSD my boot time now is about 10 times faster! I can get to my desktop in about 12 to 15 seconds now after turning it on.
I installed Windows 10 as the OS and it is very responsive. I am also running a Windows 7 Virtual machine using VMware in Unity mode. On the old hard-drive the VM was really too slow to use but now with this Sandisk SSD it runs very smooth. I use windows 7 Media Center VM to record TV shows from a USB TV tuner. It records and plays back just fine now where before it was jittery. I can highly recommend this SSD.

5.0 out of 5 stars Great Boost on an old Laptop!
Reviewed in the United States on February 28, 2016

Installed for a few days as of writing this. I replaced a 3500 rpm hard drive. The speed may not be the top of the line on this SSD but it crushes the platter based HDD. I use an ACER Aspire 5742 PEW71 with a 2.0 dual-core intel pentium CPU and 8Gb of RAM with windows 7 home premium. Boot up is as fast as I think it could get unless the OS logo video can play quicker b/c as soon as the windows logo gets done flashing on the screen, BAM! Your at the login screen. It only takes about 10sec for the wifi to connect and your ready to go. I haven't really had a chance to see if this drive will increase my laptop's battery life. So far the first night I unplugged it and it still states my general max life time of 2hrs but I didn't get to run it out with a timer going to verify. I didn't expect it to run as quickly as it is so for this price unless you do some heavy gaming or need more space this will give your older system a turbo boost. I can't say for windows 8 and I would caution anyone who hasn't installed 10 to avoid it like the plague until they really work te bugs out as I've noticed people said they had issues with this drive on windows 10.

4.0 out of 5 stars Still running like a dream since mid-Summer 2016.
Reviewed in the United States on October 24, 2017
Verified Purchase
I put Windows 10 on this thing and have been able to run my Desktop Computer with it as the OS Drive still have over 80 GB of Free Space Remaining after installing messenger apps and other basic programs on the same drive. It DOES go down to way lower amount of Free Space remaining, like 30 GB left or so, whenever I record raw game capture footage with OBS or download a lot of YouTube videos at once in between moving them over to my "entertainment media" drive(s)/folder(s).
They say you're not supposed to do video capture on a solid state drive-- I should probably do more to follow that advice-- but I haven't run into any noticeable file corruption or slowness thus far. Had it since summer of 2016, works like a dream. Still runs as smoothly as when I first installed it, or if it hasn't, I certainly haven't been able to notice.

NICE! Works just like a mechanical drive, just ALOT faster. I am no expert, but my expectation is that this SSD will have greater reliabilty and robustness since there are no moving parts. This SSD was competively priced compared to mechanical harddrives and as long as expectations for reliabilty are met, it is a great value.

Reviewed in the United States on August 22, 2016

I purchased 20 of these for my small company. My company mainly uses their workstations for email and web surfing - nothing too intense for these little drives to handle. Or so I thought. Within one year 10 out of 20 have died. Completely crashed. This is unacceptable.

The first return process was not bad (I've got more that have died and need to be returned), but that doesn't ease my distaste for 50% of my workstations crashing over the course of 10 months. Spend the extra cash on a better SSD to avoid buying this product.

Bought a pair of these for my laptops. Install is a snap. Both system run faster, quieter and cooler now. I decided to go with the smaller capacity to save money since I store my music, videos, etc. on my NAS. Win10 boots up a few seconds quicker and runs smooth.

5.0 out of 5 stars New life for an EeePc
Reviewed in the United States on April 20, 2016
Verified Purchase
This SSD helped rescue a former Win-XP EeePC into a very capable Lubuntu tablet. The EeePcs are noted for being way on the slow side of the field and need all of the help that they can get. Teaming a respectable SSD with the light version of Ubuntu brings this old tablet back to life. Going from a 5400 rpm disk to a solid state drive and adding another gig of ram is a noticeable change during operating system installation.

Dankeschön für den schnellen Versand! Am Vortag bestellt und am nächsten Tag war die M2-SSD da...Top!

Die Z400s funktionierte natürlich einwandfrei... Sie ist zwar nicht das Top Produkt von SanDisk, verrichtet aber ihre Arbeit bis heute im Wohnzimmer PC tadellos. Auch die Montage ist einfach und macht wie alle SSD's keine Probleme.
(natürlich wird sie als Windowspartition genutzt)

4.0 out of 5 stars Muy buen SSD barato
Reviewed in Mexico on January 23, 2017

Este SSD le dio una nueva vida a mi viejo laptop que antes andaba lento como tortuga y ahora vuela como águila. El SSD NO es tan rápido en comparación con otros SSD más sofisticados en el mercado, pero es cinco veces más rápido que un disco duro mecánico, además, el NAND que usa es sorprendentemente el más caro MLC y no el barato TLC, lo que se supone que le puede dar una vida relativamente más larga, en este caso, según Sandisk, unos 72TB el Total Bytes Written. Los materiales son baratos, casi todo de plástico, pero con este precio y el NAND MLC, es justo. Este SSD también es uno de los que más ahorra la energía por la falta de un llamado "second over-provisioning". En fin, estoy satisfecho con el producto. Es ideal para quienes busca un SSD básico y confiable.

5.0 out of 5 stars An efficient primary drive for the system
Reviewed in India on August 10, 2016

Delivered in 3 days. The product is excellent for its price. For entry level SSD users this is no brainer. Works well as a replacement for my dying 5400 rpm Hitachi. Windows 10 takes about 5 secs from logo to login screen, Total system startup including POST is about 15 secs. Installation was effortless. OS install was done in about 20 mins. Softwares are very responsive too. Photoshop loads up in under 10 secs. Same goes for Illustrator and Premiere Pro. All in all a great buy.
