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

Lasted 7 years

Great specs, but high price. Maybe worth it for the reliability, I am happy with this and will likely look into a larger capacity in the future I have usually had good experiences with this companies product and this was no exception. No crashes, but I would still recommend not relying on it %100 for backups.

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 recently bought a new 21 1/2 iMac with a fast processor but only 8GB of RAM. The performance was quite disappointing. As a professional software developer, I make heavy use of my machine, running several applications at once for coding, testing, and editing graphics. The iMac was constantly swapping out memory to the slow internal hard drive and it was KILLING me! On the advice of co-workers, I purchase this drive, along with and external USB enclosure. I then set it up as a bootable drive, and restored my back from Time Machine. With the drive plugged into one of the USB-3 ports, the machine boots in about 30 seconds (instead of 3-4 minutes) and comes up to the desktop in about 10 seconds after logging in. Testing with the Black Magic Disk Speed Test, it does about 400 MB/s write and 425 MB/s read. This is roughly four times faster than the internal hard drive. Also, I can keep open three browsers, three different development environments, two graphics editors and two virtual machines and the iMac doesnt break a sweat. Very, very pleased!

An absolutely incredible upgrade. My initial benchmarks indicate boot time at 20% of the original time, maybe lower. Database programs and processes run a lot faster when using the disk for a database. Even browsing and video is greatly sped up, as the time to load cached images and video content is very fast, so it even appears to improve the quality of the displayed video. I guess with the old green hard drives, the time the browser program takes to load the data is enough time to reduce image quality. An absolute must for any personal or computationally intensive business computer. Certainly good for servers too.

Holy crap. I bought this out of desperation and hatred for my Late 2011 Macbook Pro. The thing has been a piece of junk since I bought it and even 3 apple stores have said that something is wrong because its so slow...but it passed all their tests...so nothing they could do. That MacBook took over 15 seconds to open any app...since the day I bought it. It could barely turn itself on. Bottom line: I read J. Perkins (posted 8/30/14) and Andrea Polks review (posted 8/17/14) and made this thing happen in so little time. I bought the harddrive, the Inateck 2.5 USB 3.0 external case (http://www.amazon.com/gp/product/B00FCLG65U/ref=ox_ya_os_product_refresh_T1) and cloned the whole Macbook harddrive. That took hours, I think 13 or so...but I had over 450GB on the HDD. I had to go to Home Depot and buy a small Torx bit screwdriver, because I didnt have a T6 (tiny). I looked up how to select the external (SSD) as my startup disk for the Macbook (have the computer ignore the installed drive on start up and load the OS from the external/SSD). The computer worked, was already faster so I decided to go for it. I took the back of the laptop off, carefully removed the hard drive and placed this SSD in there. I had to use a small furniture cushion as a spacer between the case and the drive to keep it secure but THEN... I started the computer, its super fast, opens every app within seconds (Ive actually started the computer and clicked every app at the bottom to watch it load up super fast). Totally worth it, honestly like a new computer. Ive since formatted the old Macbook hard drive, removed the mounting screws and its not installed in the inateck case as a 500GB external harddrive to store GoPro and pictures on. Wife = happy.

AVOID!! I purchased 2 of these drives. The first failed within 1 week. SanDisk sent a replacement. The second (the original, not the replacement) then failed 4 months later. Thats 2 out of 2 failed! Usage was mostly just read. There is clearly something wrong with this model. Infuriating for such an expensive drive. I have several of SanDisks 480GB Extreme II drives and had no problem with those. But SanDisk has lost a customer. I am buying only Samsung from here on out. No problems with the Samsung 850 Pro 1TB and 850 Evo 1TB. Given the Samsung firmware fiasco with the 840 Evo, I was trying to avoid Samsung. But Samsung drives have never failed like this. UPDATE: now it is a year later 11/17/2015 2 out of 2 of the replacement drives also failed. Now today, yet another failed. Every single 960GB drive I have purchased, or have been sent as a replacement, has failed. These are running windows virtual machines on esxi (mostly read, not as server, are used as web browsers). I have never had this problem with any of the Samsungs or other brands I have used. This is totally unacceptable. I wasted $1,500 on these drives and untold hours having to reinstall, take the hardware down, etc. Never again.

Extremely fast SSD. I wanted to use it as the sole drive in an older PC (with an ASUS model P7P55D PRO motherboard), but was reluctant to connect the drive via the relatively slow SATA II interface on this motherboard. Instead, I mounted the drive on an OWC Accelsior S (PCI to SATA Drive Mount card; see product link:

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.

SanDisk has always had a reputation for quality products and this SSD is no exception. With the cost of SSD drives falling it is not hard to justify an upgrade if you are still using mechanical hard drives. This is a great price for a large capacity drive like this. I still use a mechanical drive for bulk storage, but all my programs run from this one, and you wont believe the difference in the response of your computer when you upgrade to a SSD. I have no problem recommending this drive, it is top-quality all the way.
