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

Pros: Fast read/write speeds, decently priced Cons: None When it comes to SSDs, there are manufacturers who use their own controller and there are ones who use third party controllers. SanDisk uses Marvell controllers, which are pretty popular. This SSD is built for performance with similar specs to the Samsung 850 Pro. The Samsung, however, uses its own controller, which you can argue is better because they have direct control over the components that go into the SSD, but you probably wont be able to really tell the difference during normal usage. At the time of this review, the Sandisk is $189 vs $217 for the Samsung. If youre looking for a primary SSD for your OS, this wouldnt be a bad choice. The Samsung 850 and 950 are also good, but they tend to be a bit more expensive with similar specs. Intel SSDs are also top of the line, and the price reflects that.

This was my first SSD. I was torn between this and a Samsung EVO. Really, it was the 10 yr warranty that swung me to the SanDisk. Since longevity it still a concern with SSD, I dont regret spending a little more for the piece of mind. It worked flawlessly on initial fire up. Its my OS drive and I had zero issues installing Windows 8.1 on my brand new gaming rig I just built. Holy crap does this thing boot up fast! The main specs of my PC: ASUS Maximus Hero VII Intel 4790K PNY GTX 770 OC 4GB 16 GB ADATA 2400 WD 1TB HDD

I did a side by side of two Dell e6540 laptops (brand new, same image, specs, etc). Only difference was the SSD and the HDD. The HDD was getting around 100 MB/s seq read and 95 MB/s seq write. On the SSD I get around 515 MB/s seq and 485 MB/s write. The SSD system is very snappy whereas the HDD will spin frequently. I went with this SSD over the Samsung based on the reviews from Anand Tech and Toms hardware. I did check prices today however and the Samsung 850 EVO 250GB is only 89 bucks. I bought this one last week for 130 but it is 119 today. If money is tight and youre trying to get the absolute biggest bang for your buck, you might want to look into the Samsung but if you want the best, I dont think youll be disappointed in this at all. If Anand and Tomshardware recommend it and claim its the best, you cannot go wrong.

i7 Quad Core/ 16GB/ MacBook Pro early 2011. Has worked flawlessly. Apps like Mail and iPhoto that took 30/50 secs respectively to load (I have lots of mail and photos), now launch in 3/5 seconds. Used USB Sata cable and Carbon Copy Cloner to copy system to drive, swapped drives and everything worked, all licenses transferred (except Google Drive needed to be rebuilt). Speed tests (Blackmagic) Show average 515 MB/sec read and 435 MB/sec write. No degradation in speed from first test (a few weeks ago) till now. I think Apple tests their OS with flash drives, so as they increase the Input/Output read write counts when adding features/security protections, they dont notice the issues caused in systems with using hard disks. If you have Yosemite, you need a drive like this. Unfortunately, because apple doesnt support Trim for macs w/3rd party SSDs, you should also plan to replace your drive every year. I do upgrade my drive each year, as I need lots of speed and space. The last three were hybrid SSD/HDD (512MB Seagate/1TB Seagate/1TB Toshiba). The hybrids were slightly faster than a 7200 RPM disk initially, but after a year, each was slower than a stock clean 5400 RPM.

I have a MacBook Pro (mid 2009) (MacBookPro5,3) and had been noticing recently that it was spending more time than usual waiting on the hard drive (spinning disk). Having had similar issues over the years with PCs running Windows, I decided it was time for a new hard drive. I could find very little information about this SSD being installed in my generation of MacBook but decided to take the plunge. I decided to physically remove the Macs optical drive as well because it was no longer in use and I felt that it was holding down the SATA speed to 1.5 gigabit which was experience in other PCs. After removal, I filled the slot with silicone to prevent someone from putting a CD in the slot as well as to not cause any airflow issues for cooling. I plugged the SSD into my USB port using a special cable and then used Carbon Copy Clone to transfer all the data. The number of used bytes on the SSD went down dramatically probably because the hard drive marked sectors as unusable. After I physically installed the SSD, a boot was lightning fast and the SATA speed was now 3.0 gigabit.

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.

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.

Works as advertised and was easy to install. Used the clone program referenced by another purchaser - Macrium. Very fast at sata3 and still fast at sata2 (180 MBs on old pc). Programs and files load almost instantly and should make the old desktop pc useable for the next couple of years. The old 500gb drive is used for DATA and the new C-Drive is used for the operating system and programs. I did not want to remove the DVD drive so I just put it in the same mount. It fit perfectly between the DVD drive and the cage around it.

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!

Works flawlessly with my Gigabyte GA-Z97X 3 motherboard. Very quick load times (comparable to my old Samsung Pro 850 drive. I used Marcium Reflect to clone my existing spindle-based HDD to the SanDisk. So I cannot attest to the SanDisk cloning software that you can download from their website. For the price, this SSD is really a no brainer. Im very, very happy and plan to buy more for other machines in my office.
