SanDisk Extreme PRO 240GB SATA 6.0Gb/s 2.5-Inch 7mm Height Solid State Drive (SSD)

Samsung Pro has double the endurance specification (marketing?) and half the warranty for their Pro TLC drives. Most enterprise drives use MLC memory so I came to the conclusion that it is better. I pick this up on Amazon Warehouse deals. Had one terabyte written in its previous life. Dash board shows the wear out to be 0.26%. Still has the 10 year warranty when I went to register the drive. Well worth it for an additional fifty dollar savings at the time.

This (240GB) has been absolutely flawless in an HP 8200 elite (Q67 chipset) running Windows 7 x64. Performance is in line with what was advertised, and what other sites benchmarked - and it hasnt slowed down in the few months Ive had it (unlike the 840/840 Evos). Windows gets partway through the flag animation, then goes right over to the login screen. Nice! Update: The desktop is still working perfectly, 8 or 9 months later, hasnt noticeably slowed down or anything. No stability issues. I just bought a 480GB one for my zbook 14g1. That one, too, is working like a charm thus far. If I need any more SSDs, theyll be Extreme Pros or Ultra IIs from now on. Update: Ive since tried one of the drives in a Zbook 14 g2, and a Lenovo t440s. Works like a charm in everything, and unlike other drives, these dont falter under load. Throw a 200GB transfer at these and Windows (resmon) shows 25% usage while maxing out a gigabit link. (Unlike other drives, that advertise similarly high speeds but suffer if you give them a huge file transfer and dont give them time to TRIM afterwards.) Ill definitely buy another one of these should I need it.

I purchased this SSD to replace the HDD that came with my laptop. Using the free utilities to transfer all of the data from the computer was really quite easy and only took about 30 minutes (youll need to buy a USB 3.0 SATA III hard drive adaptor cable if you dont already have one). Once the data was transferred I was able to install the drive and it booted right up. Performance for my laptop has improved dramatically. After running benchmark tests between the HDD and SSD, the SSD read and write speeds are over 6 times faster than the HDD. The machine itself runs noticeably faster, quieter, cooler, and the battery life is much longer as well.

I have edited this review, changing it from 3 to 5 stars, after looking into the reason for poor performance on my earlier review. A SanDisk rep pointed out that the performance should be better, so I looked into it. It turns out that my ASUS Maximus V Formula ROG gaming motherboard has two SATA controllers. One pair of SATA/600 ports is supported by the Intel Z77 chipset, and four other SATA/600 ports by the Asmedia chipset. The Samsung was connected to the Intel SATA port, while this drive was connected to the Asmedia. The Asmedia chipset was underperforming, not this drive. Poor performance can also be cause by using an old spec. SATA cable. These are the Crystal DiskMark test results with both drives connected to Intel SATA ports. The first column is for the Samsung, and the second is for the San-Disk. Sequential Read : 500 MB/s 495 MB/s Sequential Write : 450 MB/s 488 MB/s Random Read 512KB : 426 MB/s 335 MB/s Random Write 512KB : 369 MB/s 431 MB/s Random Read 4KB (QD=1) : 28.5 MB/s 30.6 MB/s Random Write 4KB (QD=1): 56.4 MB/s 64.6 MB/s Random Read 4KB (QD=32) : 280 MB/s 396 MB/s Random Write 4KB (QD=32) : 142 MB/s 291 MB/s The SanDisk is better than the Samsung in a number of benchmarks (especially the last), while there are some where the Samsung is a little faster. Benchmark results can vary by 10% or more, so most differences would be unnoticeable. So, the bottom line is that this is a good drive, and if it does not melt down tomorrow i plan to keep it for a long time.

Best thing I could have bought. It made my wifes MacBook Slow into a MacBook Pro (event though I am not a fan of Mac). It used to take her 2 minutes to turn on, 15 or 30 seconds to get to home page from sleep, and 8 minutes (how crazy!!!) to open up LightRoom or PhotoShop. Her computer had that stupid beach ball spinning all the time, and all the programs ran slow (her computer is barely over a year old). I copied her hard drive onto this SSD and we havent had one problem since! Her computer will come all the way on and at home screen in about 15 seconds, when from sleep it is right up by the time it is all the way opened and once you enter password it is right at home screen, no wait. Also you can have a ton of programs open and it doesnt have any delay or lag switching between them. LightRoom and PhotoShop open in a mind-blowing 5 seconds compared to 8 minutes. I didnt know the SSD would do that for her computer but I am slow glad it did and I am forever grateful to SanDisk! Awesome product!

I purchased a new laptop and installed this drive. Its very fast- rebooting takes only seconds and I can quickly access any file on my system. Furthermore, transferring photos from a camera is much faster, particularly via USB 3.0. So far this drive has done everything Ive asked of it and has met my expectations in every way. While I have not pushed its durability (e.g. dropped the computer, etc.) I suspect it is much more resistant to damage than a traditional mechanical drive. I would recommend it to anyone looking to upgrade their systems storage.

Absolutely amazing, took my mid 2011 iMac running Mavericks from a boot time of over a minute to under 10 seconds with absolutely no lag. I cannot recommend it enough - the pro class is definitely the way to go with an SSD and the 10 year warranty is just the icing on the cake. It makes my old iMac feel like a totally different and new machine. With it more than 1/2 full (190 GB FREE), it still is clocking in at 380-410 MB/s read and write - definitely work the money.

I have had this model of SanDisk SSD (first one returned to SanDisk about a year ago) for just over 2 years. The SanDisk drive is installed in an HP Mini 2102 laptop, that was initially running dual-boot, Ubuntu 1604 and Windows 7 Starter - 64bit. In August 2016, I took advantage of a free ugrade to Windows 10 Home (later I observed this was the 32 bit version of Windows 10 and suspect the switch in bits was related to the Atom processor in the laptop). What a mistake I made. The first problem I observed was screen updates were sluggish and large pauses would occur. I suspected a video driver issue and proceeded to update drivers using a third-party software solution. No changes. Next thing I knew Windows 10 wanted to update to 1607. The upgrade process required a lot of boots and many of them would hang with the disk activity light solid. Contacted SanDisk and they decided to send me a new drive. After restoring from a backup, I was able to get the update to 1607 to complete with only a couple disk hangs while booting up only. I was now observing the disk activity light a lot more. When screen updates would hang, I now noticed the disk activity light being solid and would recover , 20 seconds being the longest. I started using hibernate a lot more to avoid the solid hangs. Also, I observed that when Ubuntu got sluggish, the disk light would go solid, but would recover in less than 5 seconds. Now Windows 10 update 1703 becomes available around April 2017. For some reason, I decided to move the SanDisk SSD to another laptop - HP HDX 16. The update to Win 10 1703 went without a single hang in the HP HDX 16. My conclusion is the SATA/??? controller on the HP Mini 2102 has problems or the driver-controller has issues. The Windows 10 Home driver being much worse than Ubuntu 16.04 driver or the Windows 7 Starter. Going to contact SanDisk again to see if any updates from a year ago and share my experience. Should contact Microsoft about the 32 to 64 bit switch-aroo since the drive may be going into a computer with a lot more memory than the 2.97GB restriction for 32 bit. Or, visualize it on Ubuntu 17.04 64 bit.

This is STUPID FAST!!! Had to get it for my new Dell Laptop. The new Inspiron 7000 series with the new 4K screen is very slim and sleek. Highly recommended if you are in the market for a new laptop. Only downside is the SSD drive I had in my old laptop is too thick. So kind of a bummer had to buy another SSD. Decided to go up to the 480KB from teh 256 Curcial Technology drive that I had. Great drive too, but this is a few notches above it. Windows 8 loads in 5 seconds flat on this thing. Absolutely nuts! The reviews seem to indicate this should be a solid performer and have great reliability. Time will tell on that end, but I can assure that the speed is there! Is it worth the extra $50 or so to upgrade form the Crucial? That I leave up to you, for me I would rather spend the extra money and know I am getting the best. But I have two Crucials and they have both performed admirably, just decided to try SanDisk this time based on the online review magazines. Highly recommended.
