The new SanDisk Extreme Pro v2 comes with some changes under the hood, too. A new ASMedia ASM2364 bridge controller communicates with the host at faster speeds because it has twice the PCIe lane count as the ASM2362, which means twice the throughput. Not only does it maintain a speedy 20 Gbps link while connected to a PCIe 3.0 x4 SSD, but it also features link power management to reduce idle power consumption. The controller also supports Trim to keep performance predictable.
USB 3.2 Gen 1 (a.k.a. the old USB 3.0), typically good enough a ceiling for older external SSDs with SATA-based silicon, caps read and write speeds for external SSDs at about 550MBps and 500MBps respectively. While you can use the Extreme Pro V2 drive with any of these interfaces, buying it without provision for a Gen 2x2 interface would be like buying a Corvette for runs to the grocery store. As for IOPS - what is the point of testing the device outside of its designed enclosure if it is forever going to be used in the enclosure? I can test portable SSDs' IOPS perfectly fine as they come. They are not going to be used as internal SSDs, only as portables. So, comparing the performance without the bridge chip they come with is irrelevant. And again, I've already reviewed the internal devices as linked above. ;)Whether you’re trekking through snowy mountains or filming in the middle of the desert, this drive won’t let you down. Overall though, if you discard the far cheaper alternatives from lesser known vendors, there’s little incentive for Sandisk to drop the price of the G-Drive further. That is particularly true given the presence of the speedier and far more expensive G-Drive Pro SSD which carries a 50% premium and a near-200% improvement in speed thanks to its Thunderbolt 3 interface. 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. 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.
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. You do get a five year warranty with it but you will have to send the defective drive to Sandisk at your own expense. It is worth noting that if you use a data recovery service, you will not void an otherwise valid limited warranty as long as you get a written verification from the service provider. The competition 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. TB3 is more popular then USB 3.2 2x2 which is impossible to find in notebook and very rare in Desktops.
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.
At that point you wouldn't be testing the actual portable SSDs as they are, you would just be testing the performance of the internal SSDs in that one enclosure. Thus, comparing just the underlying storage alone. You can't compare the performance or thermal characteristics of these portable SSDs without using the default enclosures and bridge chips.On a positive note, the drive comes with two 9-inch cables: USB-C-to-USB-C and USB-C-to-USB-A. That's better than an awkward converter dongle. nofanneeded said:TB3 is more popular then USB 3.2 2x2 which is impossible to find in notebook and very rare in Desktops. We’re looking for 2TB superfast, extremely rugged, IP67+ rated external solid state drives. That disqualifies the likes of the popular Samsung T7 Touch which is not waterproof. 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.

I'll look into it. Is there anything specific you are looking for? You don't have permission to access "http://www.argos.co.uk/browse/technology/computer-accessories/external-hard-drives/c:30073/storage-capacity-(gb):2tb/" on this server. Tips: Smaller cluster size makes less wasting of disk space. It is recommended that you use the default size if you don't know which one is better. Up to stated speeds. Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes.The Extreme Pro is IP55 water and dust resistant and rated to withstand a two-meter drop, though we feel that is a very conservative rating. At 85 grams, the Extreme Pro has a solid and weighted feel to it. That, along with the smooth rounded silicone-coated edges, conveys an apple-esque quality. 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. nofanneeded said:This is not true , because the internal hardware of TB3 drives tested does not match ... If you want the best out of TB3 , you should get an empty TB3 box and put the best NVME SSD inside it. Interesting. I assumed that "refreshing" the charges/data was one of the routine maintenance tasks of the SSD controller and assumed that it would be done on a routine/scheduled basis. If the data is stable for 10 years then it makes sense that this is not done. I assumed the stable time was a lot less then 10 years.
Great Deal
