Description

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. nofanneeded said:Because all portable SSD are a box with internal off the shelves NVME SSD .. I am 100% sure you will find the same Version of SANDISK Extreme Pro as a stand alone NVME ... 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. seanwebster said: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. TB3 is more popular then USB 3.2 2x2 which is impossible to find in notebook and very rare in Desktops.

Get fast NVMe™ solid state performance featuring 1050MB/s 2 read and 1000MB/s 2 write speeds in a portable, high-capacity drive that’s perfect for creating amazing content or capturing incredible footage.Save time storing and transferring data with the forged aluminum chassis that also acts as a heatsink to deliver higher sustained speeds. 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. 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.

From SanDisk, the brand professional photographers worldwide trust to handle best shots on their toughest assignments. SanDisk provides a generous five-year warranty, which we have also seen on other Western Digital products such as the 2020 version of the My Passport SSD. (WD is SanDisk's parent company.) 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 table below presents a comparative view of the specifications of the two portable SSDs covered in this review. Comparative Portable SSDs Configuration Neither the name of the University of California, Berkeley nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission.Prior to looking at the benchmark numbers, power consumption, and thermal solution effectiveness, a description of the testbed setup and evaluation methodology is provided. Testbed Setup and Evaluation Methodology There are plenty of external storage solutions out in the market, but very few of them will be as durable as the Extreme Pro Portable SSD. It’s got great transfer speeds to keep you going, plenty of storage, and comes in a variety of storage sizes. In a thread about 4TB Extreme Pro drives in a film and video editors subreddit, a Reddit user called ian__ wrote: 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. Can you please gather the best NVME external boxes in the market and test them with something like Samsung 970 Evo Plus or 970 pro ? make a round up ? and see if they reach 3000MB/s ???

SanDisk Extreme Portable SSD - WD Support SanDisk Extreme Portable SSD - WD Support

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. Both drives support S.M.A.R.T passthrough. X6 does not indicate TRIM as an available feature. However, we were able to activate TRIM in Windows on NTFS volumes in both drives. Temperature monitoring and obtaining health status (in terms of TBW) are simple for both drives.The evaluation routine for direct-attached storage devices – portable SSDs, storage bridges (including RAID enclosures), and memory cards – all utilize the same testbed and have similar workloads with slight tweaks based on the end market for the product. Our testbeds have kept pace with the introduction of new external interfaces - Thunderbolt 2, Thunderbolt 3, and USB 3.2 Gen 2 via Type-C. In mid-2014, we prepared a custom desktop based on Haswell, which was then upgraded to Skylake in early 2016. A botched Thunderbolt 3 firmware upgrade on the Skylake machine meant that we had to shift to the Hades Canyon NUC starting in early 2019. This year, we have adopted the Quartz Canyon NUC (essentially, the Xeon / ECC version of the Ghost Canyon NUC) along with build components from ADATA Industrial - 2x 16GB DDR4-3200 ECC SODIMMs and a PCIe 3.0 x4 NVMe SSD - the IM2P33E8 1TB. Some unconfirmed chatter suggests that the SanDisk Extreme SSD issues affect only those using devices "manufactured after November 2022." Still, at the time of writing, we would advise anyone using these drives to use them with extreme caution. Perhaps it is advisable to only use these storage devices for convenient duplicate or temporary data until the fix arrives and it has been tested well. The SanDisk Extreme Pro V2 supports the latest and fastest USB flavor (USB 3.2 Gen 2x2, also called SuperSpeed USB 20Gbps), which offers transfer speeds of up to 2,000MBps for both read and write when connected to a compatible USB-C port. It tested just short of that (1,909MBps read, 1,919MBps write) in our Crystal DiskMark 6.0 sequential read and write testing. Its scores were also a smidge under the speeds we recently saw from the Seagate FireCuda Gaming SSD (1,992MBps read, 1,967MBps write), which supports the same 2x2 interface. (See how we test SSDs.) Because all portable SSD are a box with internal off the shelves NVME SSD .. I am 100% sure you will find the same Version of SANDISK Extreme Pro as a stand alone NVME ...
