Built by a technology leader
More than 25 years ago SanDisk created the world's first flash-based solid state drive and that was just the beginning. As a technology leader, we ensure that our products continue to deliver superior performance that you can rely on.
 Based on internal testing; performance may be lower depending on drive capacity, host device, OS and application. 1MB=1,000,000 bytes.
 IEC 60529 IP55: Tested to withstand water flow (30 kPa) at 3 min.; limited dust contact does not interfere with operation. Must be clean and dry before use. 4 Shock‐resistant (up to 1500G) and vibration‐resistant (5 gRMS, 10‐2000 HZ), non‐operating temperature (from ‐20°C to 70°C), operating temperature (from 0°C to 45°C).
 Up to 2M (6.5’) on a concrete floor.
 1TB = 1,000,000,000,000 bytes. Actual user storage less.
That said, if you plan to use this drive for anything other than movies, music, and pictures, you need to format it before using it. This is especially true if you plan to use the drive to back up your phone or computer. Out of the box, the drive is formatted with exFAT and an allocation size of 1 MB. That means that any file less than 1 MB takes up 1 MB of space. 1 MB may not seem like much on a 250 GB-2 TB drive, but with the myriad of small files that show up on backups taking up 1,000x more space than normal, it adds up. See the attached pictures for a small text file taking up 2,700x more space than it actually is and a 177 GB backup taking up an extra 73 GB on the drive.
I mention this because it's an easy fix. According to the command line, the sector size on the drive is 512 bytes, meaning there is no reason to have an allocation size that large. All you need to do is format the drive as exFAT and select a smaller allocation size than 1 MB. Microsoft recommends 128 KB, but you could go as small as 4 KB or as large as 256 KB and still be far more efficient than the factory 1 MB allocation size.
Every action you do with the drive, whether it be transferring files on, transferring files off, it'll hang randomly. I bought the 1 TB Hard Drive and I can't transfer 5 GB without it hanging at 2-3 GB's and just freezes completely (see attached for error).
Can't open up Lightroom cause the Portfolio freezes before it fully opens. Every hard drive I have on my computer works, except for this one.
5 years of travel photos loss. I am never buying SanDisk again, sticking to Samsung SSDs from now on.
This is the first time I've had a serious problem and it's an insidious one. After a couple of months of ownership, I am having a problem with it corrupting a file when I save it, with no message or error notice. Come back a few hours later and the file is either missing data or is altogether unreadable and all my work is lost.
With an internal SSD on my MacBook Pro it made perfect sense that the destination backup should also go on an SSD drive where transfer speeds would significantly increase. One more thing to consider: spinning hards drives have a much higher failure rate than SSD drives. I can't begin to tell you how many spinning backup drives I have purchased in the past that have ultimately failed.
SSD is the future and the fact that prices have dramatically decreased on these drives gives no-one an excuse for not buying them.
I did a lot of research on various SSD drives before selecting this SanDisk 1TB drive. My first choice was a Samsung in a colorized metal case. The reviews, however, led me to believe that there were some major issues with the Samsung drives as they included embedded software that was difficult to remove. This is not something anyone wants when buying an SSD drive.
Reading the reviews on this SanDisk Extreme, it was easy to see that this would fit perfectly for my needs. The reviews across the board were very positive. No embedded software. This particular SSD has been rated as one of the very fastest USB drives available on the market as of this date.
Upon arrival, I was astonished at how small this drive actually is. I mean, it's absolutely tiny. You can fit it into your jeans pocket and you would not feel it. We really have come a long way in external SSD drive portability.
I am not particularly happy with the covering on this drive. It's a dust magnet. The second I placed it on my table it had already collected airborne dog hair. However, on the plus side, this thing is so rugged that you can drop it from just about any height and it won't break. So, I guess that is more important than anything else.
It was nice to see that the drive includes a USB-C cord with USB-A adapter. The cord also securely fits the drive without any wiggle. The only thing negative I have to say about the cord is that it's too short.
I am including in my photos the result of a recent backup of my MacBook Pro via SuperDuper software. You can see that about 425GB of data was backed up in 30 minutes time. With a spinning drive, that would have taken 2-3 times longer. This drive is really super fast!
This drive does come formatted for Windows. If you buy it for your Mac, you need to go to DISK UTILITY (in your applications folder), select the SanDisk drive, then click on ERASE. You will want to format the drive in OSX Extended Journaled. The format takes seconds to do. You are then ready to transfer data to the drive.
By far, this is the best SSD drive I have ever owned. Do not hesitate to consider this above any other.
