The SanDisk Extreme Pro Portable SSD V2 is SanDisk's flagship portable SSD, boasting read/write speeds up to 2000MB/s - that's nearly twice as fast as the non-Pro version (some retailers aren't using the 'V2' designation though, so look out for the 2000MB/s performance rating to ensure you're getting the right SSD version). 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 tested the Sandisk Extreme Pro 1TB external portable SSD using a Dell Latitude 7490 business laptop which is equipped with a Thunderbolt 3 port. Note that the Extreme pro Portable SSD v2 includes support for hardware encryption via the Sandisk SecureAccess application. 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. 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.

What's more, the drive is also well-made and durable - it's designed to survive being dunked in water or being dropped from 2m - which gives you confidence that your files will be kept safe.

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. 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. 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. 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. 1A full install of Call of Duty: Modern Warfare II with the Warzone 2.0 Battle Royale mode will take well over 100GB on the internal SSD. Ditto for Forza Horizon 5. Go for this year’s big exclusive, Starfield, and you’re looking at around 125GB. Sign up to Xbox Games Pass and make use of its extensive library, and you could see your available storage space reduced to zero before you know it. Designed to work with both Windows and Mac, the SanDisk Extreme® Portable SSD is equipped with a USB 3.1 Type-C connector and also includes a USB Type-C to Type-C cable and a Type-C to Type-A adapter, meaning it will work with the PCs and Macs of today, tomorrow and yesterday.

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. 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. CrystalDiskMark gets things off to a good start with stunning peak sequential read/write speeds of 1440/726MB/s respectively, though this is some way short of OWC's claim of "up to 2800MB/s". Real world file transfers will always be slower than a synthetic benchmark test, but we still recorded a hugely impressive 995MB/s peak read speed when shifting one massive video file, though this figure did drop as the transfer progressed, leaving the final averaged video read speed at a more modest - though still very rapid - 645MB/s. An average 612MB/s read speed moving multiple image files is also superb, though write speeds take a significant performance hit, with an average 481MB/s when writing video and just 278MB/s when writing multiple images. That image write rate did peak at a healthier 413MB/s during the transfer, but the drive couldn't sustain this speed, hence the slower average figure. 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. Inside the toughened shell is a fast SSD which SanDisk claims can transfer data at up to 560MB/s - impressive stuff. The drive connects via an up-to-date USB 3.1 Gen 2 Type-C connection, though a Type-A converter is included to maintain compatibility with older computers.So it'd better have plenty of performance to compensate. Thankfully, with NVMe SSD technology and a Thunderbolt 3 connection promising a theoretical 40Gbps bandwidth (that's 4x faster than USB 3.1 Gen 2), the Envoy Pro EX has all the right ingredients for winning performance. Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: 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.
