SanDisk 2TB Extreme Portable SSD, USB-C USB 3.2 Gen 2, External NVMe Solid State Drive, up to 1050 MB/s, IP65 rated for dust and water resistance

Product Information

Up to 2000MB/s read and write speeds. Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes. L'ho provato sia su Windows sia su MacOS, con partizioni cryptate o no. Nel mio caso il collo di bottiglia è evidentemente le porte USB obsolete. 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. addlink ポータブルSSD 1TB P20 USB 3.2 Gen2 Type-C 最大1050 MB/秒 PS5/PS4対応(メーカー動作確認済) 外付けSSD 3年保証 ad2TBP20B32

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. The Sandisk Professional G-Drive is not your bog standard external drive. Not only is it rugged, it also comes with a five-year warranty but fails to match Seagate’s Rescue Data Recovery Service which is now bundled for free, with quite a few mainstream external SSD (like the recently reviewed Seagate OneTouch 1TB external SSD ). 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.Co BIY said:How often does an external SSD drive need to be powered up or plugged in to maintain the data ? Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: 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. A footnote about the branding. G-Tech (from which G-Drive is derived) started life as part of HGST, which was acquired by Western Digital. G-Tech survived as a rival to Seagate’s LaCie, supplying rugged, external, reliable storage devices and accessories to outdoor enthusiasts, prosumers and professionals. With the recent launch of Sandisk Professional, it is likely that G-Tech and G-Drive will be sunsetted in the near future.

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.

Integrating WD’s Blue SN550E and leveraging BiCS4 TLC flash, the SanDisk Extreme offers responsive performance in a secure and portable package.

The SSD controller and the NAND Flash memory used are unknown; however, we’d assume that it shares some DNA with the SN530, Western Digital’s entry level NVMe platform. 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.

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. Was mich jedoch wirklich fasziniert hat, ist die immense Speicherkapazität von 4TB. Das ist eine wahre Fundgrube für jeden, der große Mengen an Daten, Fotos, Videos oder Projekten speichern möchte. Als Fotograf war ich besonders gespannt darauf, wie gut die SSD mit meiner wachsenden Sammlung hochauflösender Bilder umgehen würde. Multiple DITs/Loaders/ACs on both coasts have experienced the exact same failure with these drives over the last month.The symptom seems to be that after a sustained write they will completely lose their filesystem and it's a total crap shoot [whether] you can recover it or not. The primary way you will see this is that the drive will unmount and you will not be able to get it to mount again, despite showing up in Disk Utility. You can sometimes recover it using DiskDrill's filesystem rebuild, but occasionally that does nothing. It persists with any filesystem type. Ars Technica's Lee Hutchinson confirmed suffering not one, but two 2TB Extreme Pros dying. After filling about halfway, each drive met a slew of read and write errors. When he disconnected and reconnected the SSD, it showed it was unformatted with the drive completely wiped, including its file system. Wiping and reformatting didn't help, and this happened with two different units. SanDisk SSD 外付け 2TB USB3.2Gen2 読出最大1050MB/秒 防滴防塵 SDSSDE61-2T00-GH25 エクストリーム ポータブルSSD V2 Win Mac PS4 5年保証 エコパッケージ

SanDisk’s response

From SanDisk, the brand professional photographers worldwide trust to handle best shots on their toughest assignments.

Get powerful NVMe™ solid state performance featuring 2000MB/s 2 read/write speeds in a portable drive that’s reliable enough to take on any adventure. 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. Co BIY said:Interesting.

Die solide Bauweise der Festplatte vermittelt Vertrauen in die Langlebigkeit des Produkts. Obwohl sie klein ist, fühlt sie sich dennoch robust an und ist nach IP55 staub- und wasserbeständig. Das mitgelieferte USB-C-Kabel und der USB-Adapter sorgen für eine unkomplizierte Verbindung zu verschiedenen Geräten. Save time storing and transferring data with the forged aluminum chassis that also acts as a heatsink to deliver higher sustained speeds.
