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

Being my first SSD I have no complaints. Boot time for my windows 10 5 year old computer is about 50-52 seconds.Amazing difference in computer speed when you add an SSD. By adding an SSD you also lose the spinning sound of a traditional HDD which makes your computer much quieter. Adding an SSD to an older computer can be challenging and I had to do some research but it was worth every penny. Dont forget to download Sandisk SSD dashboard from their website after installing as it is a useful utility.

Ok, you probably have read most the reviews for this product. So the only thing i would like to point out is, if you connect this SSD to a PC via a enclosure for the firs time, (at leas in my case, using ORICO 2588US3 USB 3.0 2.5 - inch SATA External Hard Drive HDD Case.), the drive will not be recognized at all, which is in contrast to what some of the reviewers commented on this product(it will show up in the windows as a hard disk ). What you have to do is (in Windows 8, Im sure for windows 7, it will be pretty much the same), go to control panel --> Administrative tools ---> computer management --> > Disk management, then you will be prompted to initialize the drive/disk. As I wasnt aware of this (i.e. initialization has to be done first) when I got the drive, I thought the disk was defective (I even took the drive to best buy to have it inspected, they thought so too). So I had to return to Amazon, asking for a replacement drive. I think the manufacture should have mentioned this step somewhere on the instructions manual sheet coming with the product. Thats why I took one star. Other than that, this drive itself is super fast. I cloned my existing hard disk (128 GB SSD ) in the laptop I just bought to this SSD drive, it took only less than 10 seconds (could be much less). A side note, Amazon makes the return REALLY easy. just print the shipping label provided by Amazon, you can either drop it off at UPS or have UPS pick it up. The replacement drive arrived even before they receive the drive Id returned. Speechless ! Thats SERVICE!

The SanDisk extreme pro was a great upgrade to my laptop. It has speed up boot times to less then 15 sec before that it took over 60 seconds or more to boot. Installing programs is lot faster than before. Going form 100mb to over 500mb read and writes speed up the computer a lot. Updating computer is a lot faster. Programs run a lot faster with a SSD. The drive is lot less fragile then a HDD. You do not have to worry as much if you accidently drop your computer about it breaking because it has no moving parts to break. This SSD is good for computer because it is durable for a laptop Because a laptop gets thrown around a lot . Over all the product works well in a laptop or tower because of how it not made of moving parts to break if you drop it. I have drop my lap top a few times and the drive still works. The program that you download to monitor it is good. It gives you a lot of info on your SSD. The product is good. Very high quality. Order came soon after ordering on this site. Have had good luck with product.

Good replacement for my EVO 850. My EVO 850 was a very fast unit except for one particular application: writing email in my gmail account online. Each time I would type, I had to wait seconds to see my text appear on the screen. I found nothing on the Internet that explain such phenomena. Everything else was blasting fast with my EVO. Following a friend idea, I ordered this unit, cloned the content off my EVO 850 onto it and gave it a try. With my naked eye this unit is very fast. There is plenty of benchmarking data for that available out there to tell you if it is faster than the EVO 850 or not. What was important for me was to be able to use my online gmail account like I was used to. And it did. Im very happy with that swap. As for my EVO 850, I got it re-purposed in another rig where Id enjoy its fast speed.

There is not a lot new here that I am going to be able to share, that many others have already shared in these reviews. This SanDisk Extreme Pro is currently the Performance favorite at the Toms Hardware website, and the reviews tell the deeper story. I have the 480 GB version of this drive, and I purchased it to use as my Operating System drive in a new Intel based Z97 Computer, and did not want to go with a PCIe X 4 M.2 Drive quite yet. Having already used the Samsung and Crucial SSD SATA drives in the recent past, I decided to read up and see if there was anything else new to research, and I came upon the reviews for this drive. Yes, the Samsung is a great SSD, and is faster in short data bursts, but if you are doing any heavy duty data transfer or processing, this is the SSD to go with. The SanDisk Extreme Pro will tear through large random data transfers and maintain high speed and not get bogged down. Using this SSD to load Windows 7 Pro for the first time was incredible due to a very short load and set up time. This SSD is a real powerhouse, and the 10 year warranty is pretty nice too. Very glad I purchased this, but I will be looking for a PCIe X 4 M.2 SSD to make things even faster. I want to see SanDisks entry into that Market, which I believe will explode soon.

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.

TIP for those using this as their primary hard drive: turn off unnecessary WINDOW SERVICES that read and write to an SSD. Reading and writing to this SSD, reduces lifespan. I will try later to update this sharing with you what services I have turned off that are unnecessary and believe me, a LOT of MS services ARE unnecessary, like ANY of the Remote services IF YOU DO NOT LOGIN TO YOUR HOME PC FROM ELSEWHERE. If you dont, turn these off as they are a security risk to begin with. I will be back later to give you all a list. OH, and be sure the TRIM feature is on by installing the SanDisk tool. Go to their site to download it. It will sit in your task bar and let you know temperature, read/write status, capacity, etc. TRIM is auto set when you install this drive, but default. Also, an SSD are CHIPS, not platters. TURN OFF: ANY disk defragger (SSDs do not require defragging) ANY read/write utilities (NOT apps like MS Office that you install) Windows INDEXING and SEARCH (turn BOTH off!) IF YOU HAVE A HDD SLAVE DRIVE like a Western Digital SATA drive (not another SSD): Move your PAGEFILE to the slave drive root for reading and writing. To save time, go to these sites and follow their instructions which fit your situation: (...)

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.

This is the best SSD drive I have ever seen. I really did my research before I decided to get one. My old SSD drive was only 150 gigs and not nearly as fast as this one. I kept getting messages saying that I was running out of space. I wanted to get the best SSD drive out there and this one was ranked as one of the fastest and I also loved the size of the SSD drive. It was so incredibly easy to install. First I got a cable so I could plug the SSD drive into my USB port and then I formatted the drive. I then cloned my drive C and just swapped the drives. The old Drive Im going to hold on to and use it as a back up just incase anything should happen. I dont think anything will happen they give a 10 year warranty and they wouldnt give a warranty like that if it wasnt any good.
