SanDisk Extreme Portable SSD 1TB up to 550MB/s read Solid State Drive

Product Information

Get extra peace of mind with a 5-year limited warranty 3 and a durable silicon shell that offers a premium feel and added protection to the drive’s exterior. The ADATA SE730H is another competitor that perhaps deserves more recognition. It is smaller than the SanDisk Extreme Portable, slight cheaper, and sports an IP68 rating making it far more resilient. Like the Extreme, it has a Type-C connector, a three-year warranty and uses 3D NAND Flash technology – but it is slightly slower and comes from a lesser-known brand.

LaCie, Seagate, Glyph, WD, Lexar and G-Technology also have similar rugged and high capacity external SSDs, but none of them have a unique selling point that would make them stand out against the T5, the SE730H or the SanDisk. The Extreme Portable SSD comes pre-formatted as an exFAT device which means that it can work on Windows and Mac out of the box. Reformattingit to NTFS will limit compatibility to Windows but will enable TRIM which will improve the longevity of the drive.Now, to answer your question, powering up the drive containing that memory does not refresh it's content. You can keep it powered up continuously, the information stored in the transistors is NOT UPDATED OR REFRESHED by the power applied to device, unless you write again the information. This principle of refreshing the data from time to time is used in the RAM memory in computers, and losing power leads to losing data.

Another thing about the flash memory is the indurance of the cell, how many times the memory cell accepts write/erase cycles until it starts to "wear" and not store anymore the information. That number is in the hundreds now days. If you read correctly the specification of an SSD drive, you will find a specification called "TBW", total bytes written. Dividing that number by the capacity of the drives yields the number of erase/write cycles that will wear the cells. We devote hundreds of hours of rigorous testing to help make sure your drive is worthy of your best work — and so you know your precious files are in good hands. We saw some good numbers here, with the caveat that the Type-C connector – not Type-A – was used. This little SanDisk product outperformed all non-Thunderbolt 3 drives we’ve tested with CrystalDiskMark, delivering nearly 560MBps in terms of read speed and just over 500MBps in write. A 100GB file was transferred in 294 seconds, which equates to a transfer rate of about 334MBps. Ruggedized design with a forged aluminum body to protect the SSD core and dissipate heat. Plus, a durable silicon rubber coating seeks to deliver higher impact resistance with its IP55 rating for water and dust resistance. 1 Get peace of mind when you’re out in the world thanks to a 5-year limited warranty 3 and a forged aluminum chassis-silicon shell combo that offers a premium feel and added protection.There’s not much competition in this price range. The Samsung T5, which costs marginally less and is far more portable, is the only rival that is widely available. It is not IP-rated, though, and its metallic surface is likely to get scratched easily. The small and light form factor of the Extreme PRO® SSD means it couldn’t be easier to keep your content with you whether you’re crossing town or traveling to an international location. From SanDisk, the brand professional photographers worldwide trust to handle best shots on their toughest assignments. When used with a USB Type-C cable, the SanDisk Extreme rises above the competition with some stellar numbers. The design and form factor are spot on and while we have one reservation regarding the bundled cable, you can’t go wrong at this price.

The Extreme PRO® SSD works with PCs and Mac™ computers right out of the box and connects with USB Type C and Type A, 3 making it easy to start and keep working in almost any situation. SanDisk Extreme Pro leverages our lightning-fast in-house NVMe technology to dramatically increase transfer speeds to up to 1050 MB/s 6 and fully saturate the USB 3.1 Gen 2 interface. 6 So you’ll be able to edit right from the drive – providing full-frame editing with little interruption while saving you time and keeping your computer’s internal storage free.Hard drives based on magnetic retention of data are better in this respect, since the retention time is greater if the device is kept properly. The drive has a rated maximum data transfer rate of 10Gbps, but in reality, it never reaches that because of the inherent limitations of the physical port. SanDisk’s Extreme v2 is a bit bigger than the original, measuring 101 x 52 x 9 mm and weighing in at under 63 grams. With a carabiner loop integrated and a durable silicone coating, the Extreme v2 features a functional, portable, and enduring design for those on the move in tough conditions. But unlike the Extreme Pro, the Extreme v2’s case and internal structure is made of plastic rather than rigid aluminum. This makes for a small and compact design that is also pretty light, but a little less resistant to twists and bending.

Flash memory based drives have now implemented a special "wear" algorithm, such that new data is written on cells that are not progammed with data, and so files are moved continuosly across the drive to mentain a balance of erase/program for all the cells, otherwise if a file is continuously written and modified on the same memory cells, these will wear after those few hundred of cycles and not be able to be used anymore. That is why a worn out SSD drive, that has reached a TBW spec, will not retain the information for long. Up to three-meter drop protection and IP65 water and dust resistance 5 mean this durable drive can take a beating. From SanDisk, the brand professional photographers worldwide trust to handle their best shots and footage.Creative professionals know the value of storage space. With capacities of up to 2TB, 5 you’ll have enough room for the files you need to work on or deliver. Save time storing and transferring data with the forged aluminum chassis that also acts as a heatsink to deliver higher sustained speeds.
