Great SSD for the price.

Reviewed in the United States on November 10, 2016

Style: 1TBVerified Purchase

This is my primary drive in a small form factor gaming/workstation Sky Lake PC. I have not done any benchmark tests but this drive is fast, also it has been in service for several months and the PC is on 24/7. The specs as to the read write speeds are the same as the much more expensive Samsung 950 Evo SSDs. I have not priced these drives lately but the Samsung 1TB Evo SSD is at least a third more expensive than the SanDisk X400 and the X400 also has a 5 year warranty just like the Evo drive. I am really glad that I bought this drive. Oh in case you do not know SanDisk is now owned by WD and when I called asking some pre sales questions my phone call was answered promptly. Also this is a bare drive, ie no cables or mounting adapters or any special software.

NOT EXACTLY A 1TB DRIVE

Reviewed in the United States on October 15, 2020

Style: 1TBVerified Purchase

Even Though It's Listed As A 1TB Drive (Unformatted)
It Really Is A 1.024 TB Drive., Or About 2.4% Higher Capacity
(According To CrystalDisk Utility).

So What's The Problem?
None, Unless You Try To Clone It With A True 1TB Drive,
Such As:
SanDisk SSD PLUS 1TB Internal SSD - SATA III 6 Gb/s, 2.5"/7mm, Up to 535 MB/s - SDSSDA-1T00-G26.
Or
Samsung 860 QVO 1TB Solid State Drive (MZ-76Q1T0B/AM) V-NAND, SATA 6Gb/s, Quality and Value Optimized SSD

Tried Using A
"WavLink USB 3.0 to SATA I/II/III Dual-Bay External Hard Drive Docking Station for 2.5/3.5-inch HDD/SSD with UASP (6Gbps) That Supports Offline Clone Duplicator Function."

But It Would Not Allow A Direct Clone Copy As
The SanDisk X400 Has A Higher Capacity Than The Two SSDs Listed.

Cloning To A 2TB, No Problem, But 1TB, Yes.

Aside From That Wrinkle, It's A Great Drive.

So far it is worth the 5 stars based on price and performance, the durability will have to wait.
It's not the fastest SSD but the performance for the cost is excellent and this 512G is a great starter SSD with enough space for Windows + several games where it doesn't seem cramped.
NOTE: If you ONLY have an SSD in your system consider having more RAM (at least 16GB) and disable your system swap file (or move the swap file to a rotating HDD). A lot of sustained writes (like from a system swap file / page file) will wear the disk down faster, although with modern technologies it's rare that you'd still have the SSD by the time that actually happened. People tend to upgrade faster and even this disk should take YEARS of 24/7 operation before it is an issue.
That said, estimates and reality don't always mesh and usually other issues cause other problems, so far, none with this one, highly recommended.

Reviewed in the United States on October 9, 2016

Style: 1TBVerified Purchase

I purchased this drive because I couldn't afford the 1TB Samsung 850pro and this one was on sale sub $300. I also have a crucial MX500 in a different computer and I didn't like it so I figured I'd give another value brand a try. I am happy with this drive, I've used it some months as a spare drive to hold misc photos and large games. It's performed well and healthy with a respectable speed.

Drive benchmark results:
Skandisk X400-
Sequential read - 554m/bs
Sequential write - 418m/bs
Random read - 96,827
Random write - 44,743

Samsung 850pro-
Seq Read- 562mb/s
Seq Write - 471mb/s
RR- 89,430
RW - 78,430

This benchmark is with samsung 850pro set to reliablity mode without boost turned on. So you can see the SanDisk keeps up respectively for a value drive. The one thing lacking with SanDisk is the software that comes with it is really sub par compared to samsungs magician. I wish they had put a little thought into that rather then a extremely basic toolkit to show drive health.

Reviewed in the United States on February 12, 2017

Style: 1TBVerified Purchase

Had this thing installed for about a year now and it's still running like a champ despite the fact that I keep my pc running almost 24/7.

Reduced loading times in applications and games and has given me a decent bump in file transfer rate. Also keep in mind that I'm still using SATA 2.0. Which means I'm not even utilizing the full potential of this drive since it is SATA 3.0 compatible.

I changed my review from 5 stars to 3 because something just occurred to me. This thing doesn't come with any mounting screws. It didn't matter to me at the time of purchase, luckily, because my pc case came with a caddy to mount the drive into. Without that caddy, i would have been screwed....because of the lack of screws.

Brought new life to my Seagate GoFlex Wifi device!

Reviewed in the United States on June 13, 2016

Style: 1TBVerified Purchase

Upgraded my Seagate GoFlex Satellite hdd to this SSD. I now have 1tb external storage device with the ability to go wireless and share media with my pc, phone or tablet.

I tried to run Crystal Disk Mark against the native sata connection however I kept running into issues trying to do the writes to the drive. However after placing it in my enclosure, I've gone from moving data at around 80MB/s to 240MB/s. I do a lot of photography so i'm moving many many files at the listed speed.

As for the wireless feature, I've now extended the battery life of my Seagate by removing the traditional rpm spinning disk. Streaming in my opinion got a little better with higher bit videos however your clearly stuck at the bottle neck that is this wifi enabled device. (based on some of my test, i'm streaming content at around 3MB/s (having the wifi drive within 10ft of target device).

I wanted to point out that this was not my first SSD that I tried to do this with, I purchased the Eluktro Pro 1tb SSD (B00QANBX8Y, you can see my review there on that). As for performance, the Eluktro put up ridiculous numbers, however because it has problems functioning in the Seagate enclosure, I had to return it. It did work great in a standard enclosure and was yielding me numbers in the 400MB/s however this was with an enclosure that supported USAP. I am giving up USAP so I can have the wifi function and still being able to transmit data at over 200MB/s is pretty boss.

The Eluktro Pro did give me better raw performance and offered the same warranty, so potentially you should look at that ssd. I am just glad that there are valued price SSD's for people that want to use them for storage only and not processing power.

enjoy!

Works well - there are plenty of performance reviews for this product and I have nothing to add to them.

The only thing I am disappointed by is the lack of SanDisk software for cloning. Initial research suggested that software is available from SanDisk - I found several links to 'offers' and several references to outdated information (don't you hate it when big websites don't clean up and provide current information?) supposedly fully functional if a SanDisk SSD is detected. None worked for me as they would not detect the SSD despite the system seeing it properly.

Clone, plugin, works. I've used these on ASUS and Acer without any issue, also used the M2 2080 in a convertible, brilliant. Tried to use the cheaper Transend, what a pain. Scandisk is Western Digital, Recommended.

Bought this to replace a Crucial SSD which suffered from incurable stalling. I think the Crucial SSD was a little faster, but I don't like my PC stopping for a minute or so at random, which in some cases was accompanied by it crashing. No such problems with this drive.
