We are replacing a old Hitachi (HGST) 5400 drive, not for speed , but to get the drop and temp protection a SSD offers over a Mechanical Rotational Disk. If we had only gotten 30MB/s it runs at, we wouldn't have complained, as speed we had wasn't an issue. But 9.8M/s is ridiculously slow. It took most of a work day to transfer just 250GB. That's not even mentioning the "It doesn't turn on" bit. We trust SanDisk, or did. We were on with SanDisk Technical Support for Two Weeks, and Sandisk's official response was - SanDisk will not guarantee speeds (ANY SPEED) unless the drive is plugged directly in to a motherboard port on a limited set of motherboards.

No other drive we tested was even close to as slow as this thing. Our Intel SSD's work just fine. (Everything the same, only unpluging and pluging in different Harddisks) We tried both Win Xp and Win 7 with no difference in speed. We really like SanDisk, and have three SanDisk SSDs from 1992 that still work today. But Intel's skull trail line beat them on speed, so most of our SSD's are Intel. But in this case we didn't need the speed, so we when with the 'trusted' SSD maker Sandisk. This has been a Huge surprise. We are returning it, and replacing it with a Mushkin. Who, we pre-called Tech Support. Mushkin says there SSD work in everything without limitations unlike the SanDisks SSD's

I would recommend this if someone is looking to upgrade their hard drive to SSD while simultaneously improving performance, mainly speed, and high memory capacity. I found this product to have one of the better Value/dollar ratio

I will for sure pick another one up eventually, maybe even 2 and put one in a laptop. Compare this to the other SSDs of the same capacity and you will find this SanDisk X400 is the best bang for the buck! The performance numbers are not far off of a Samsung 850 pro and frankly in my system, I can't even tell. Only my 950 M.2's in RAID out perform it so far.

This drive was used to replace an old disc drive. It starts up faster and doesn't create as much heat. The drive looked and worked just as new. Highly recommend these. Thanks
I decided to replace my 1TB X300 which was one year old with this new X400 1TB. Just used Acronis to clone and installed into my desktop. Seamless and effortless. Running Asus Z170-AR and I7 6700K DDR4 3200. Took my 1 year old X300, performed a secure erase on the Sandisk Dashboard and clones it into a new laptop I purchased that had 1 1TB 5400 mechanical spinner. Again, used Acronis and voila, all is well and the 5 year warranty and easy Sandisk replacement adds value.
Dropped this into a late 2008 MacBook pro and it gives a nice speed boost. Cloned the old hdd and then put the hdd in a mount and replaced the superdrive. Its a shame Apple doesn't allow the new MacBooks to be upgraded. But then they know what's best for us and how we should work.
As long as you use the X400 in a SataII older system you will be just fine. However, this leads me to the question... why on earth is this drive so expensive still??? As of the time of writing, Newegg shows $194.99?? The Samsung 860 Pro 256GB is currently on sale for $99!! And there are even cheaper alternatives. Believe me the speed of the Samsung is in excess of 500 M/s. Frankly, for the kind of money that is being asked for the X400, and the limited performance, I would buy something else these days.
UPDATE 08/11/2016: Installed in system - Core i5-4590 / ASRock Z97 Extreme4 / 16GB DDR3-2400. We're using this as our DVR recording drive because of its high endurance rating (320 TBW) and superfast response when searching, skipping ahead or back, etc. when watching recorded programs via VLC media player. VLC is a good media player that allows us to use its graphic equaliser to boost mids and highs to make dialog crisper and clearer for our ageing ears. However, when we skip ahead through the commercials VLC is somewhat laggy with our previous WD and Seagate spinning hard drives. Now, skipping ahead and back as much or little as desired it's all very snappy just like it would be if we used Windows Media Center. Windows Media Center is the best player for recording ... MoreUPDATE 08/11/2016: Installed in system - Core i5-4590 / ASRock Z97 Extreme4 / 16GB DDR3-2400.

Now, skipping ahead and back as much or little as desired it's all very snappy just like it would be if we used Windows Media Center. Windows Media Center is the best player for recording and playing back, BUT there's no tone control of any kind. Tried the X400 first as a game drive to check if it installs and loads games as well as my existing Sandisk Extreme Pro SSD, and the X400 worked just as well as the Extreme Pro. So, no problem using it as a fast data drive or for operating system drive. After a week or two i deleted the games and set it up for DVR use (the PC is also our HTPC). Some numbers: AS-SSD Seq. R/W - 502/460 4k R/W - 35/91 Total Score - 1056 Respectable mainstream performance at a few dollars above entry-level price makes this an attractive option for many users. Yes, the Samsung EVO 1TB is faster and it costs way, WAY more of your hard earned dollars. If you want bragging rights get the Samsung. However, the Sandisk X400 will boot up and open all your programs and games just as fast as the EVO, plus it has very high endurance and the 5-year warranty. All that and a much lower price. Looks like a winner. Think i'll order one.
I did a disk copy from my 2 TB HD to this copying about 400 GB of information. It took 36 minutes. I swapped the cables and fired the PC back up. The BIOS wanted to boot from the old HD. I removed the cable from the old HD and had to go into the setup to have the BIOS acknowledge the SSD. After that, it booted with not problem. I reconnected the old HD and it still booted fine. My mistake, not the device. Update on 2/28/2017 Thanks to Newegg, I sent the SSD back. I was just at 30 days. I got a refund instead of a replacement, gun shy I guess. All of the issues went away once I stuck the old HD back in AND deleted the dashboard software for the SSD. Some of the problems remained, IE crashes and problems with some gaming software, until I deleted the dashboard ... MoreI did a disk copy from my 2 TB HD to this copying about 400 GB of information.

Some of the problems remained, IE crashes and problems with some gaming software, until I deleted the dashboard software. Anyway, I paide $265 for this drive and now they are still at $265 and being advertised as $315 normally. I think after 3 months of being on sale, the sale price isn't the sale price anymore. I don't like this type of advertising. Just thought that this might help somebody looking to buy a cheap SSD. I'll wait a bit longer and probable go with more robust drive. My system because some people ask: Windoze 7 64 bit Intel Core i5-4690K Devil's Canyon Quad-Core 3.5 GHz with ZALMAN CNPS10X Extreme 120mm CPU Cooler G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM 1600 MSI GeForce GTX 1070 DirectX 12 GTX 1070 GAMING X 8G SAMSUNG S32D850T Black 32" 5ms WQHD Dual HDMI LCD / LED Monitor @ 1440 Rosewill BlackHawk-Ultra Full Tower Gaming Computer Case
Make sure you have/buy the necessary connectors for it. My system was running at about 95% storage capacity (really bad, I know) and I needed to expand. With my budget, I couldn't justify spending an extra $30-$40 on a Samsung with slightly faster read-write times. So this was an ideal choice for me.
