About this deal

Instead, I'd recommend getting a full-fledged Thunderbolt 4/3 SSD for insane speeds, since TB is a less stupid standard, just keep in mind that TB-only SSDs won't work on regular USB ports. 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. When it comes to portable SSDs, speed is of the essence, and the SanDisk Extreme Pro doesn't disappoint. With write speeds of up to a staggering 2000 MB/s, this compact powerhouse is a game-changer for anyone who needs lightning-fast storage on the go.

Looking at 4K random performance, the SanDisk Extreme hit 5,034 IOPS read and 17,053 IOPS write. The WD portable drive showed 4,330 IOPS read and 18,877 IOPS write while the Samsung T7 hit 4,204 IOPS read and 12,306 IOPS write. If your port supports Thunderbolt 3/4, it is not capable of supporting ANY USB spec that requires 2x2 lanes. Intel won't allow it. It's all or nothing. You can give up TB in exchange for 2x2, but you end up with a less useful, more expensive port with less marketing power. UPDATE: I've since gotten a M1 Max MacBook Pro. Unfortunately, this review & conclusion still stands. The new "Thunderbolt 4" ports work the same as the previous models. Even with the top of line chipsets, Intel & USB-IF's stupidity renders this drive to cap out at 10Gb/s. Only a fully Thunderbolt or fully USB 4 workflow in every link in the chain is required to hit 40Gb/s and the speeds in between. NOTE, for you to achieve ANY device's max speed, all "links" in the chain must share the same standard. For example, a 10Gb/s port will only hit 5Gb/s on an SSD capped at USB 3.0. The device, the cable, AND the computer must all support the same exact specification. I call this the "Strong Link Policy." Up to three-meter drop protection and IP65 water and dust resistance 5 mean this durable drive can take a beating.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. In 2MB random, the SanDisk Extreme posted impressive results again, with 853.7MB/s read and 836.2MB/s write. As for the other portable drives, the WD showed 720.35MB/s read and 690.24MB/s write, while the T7 that had 667.6MB/s read and 712.8MB/s write. Editor’s Note, August 17, 2023: As recently reported in Ars Technica , a critical mass of users on SanDisk’s forums and Reddit have reported failures of some SanDisk Extreme, Extreme Pro, Extreme V2, and Extreme Pro V2 SSDs, resulting in data loss, as well as the drives becoming unreadable/unmountable. In May, parent company WD released firmware updates for the 4TB SanDisk Extreme, as well as the 4TB, 2TB, and 1TB Extreme Pro models, plus the 4TB Western Digital My Passport, but complaints continue. We are doing our own stress-testing of the sample drives we originally reviewed. As of today, however, we no longer recommend buying any of the aforementioned SSDs, until we are satisfied the issue has been resolved. ( A class-action suit has been levied against WD surrounding issues with these drives.) We have left our original review in place here for reference.] The SanDisk Extreme Portable SSD also features a USB bridge that has a water-resistant Type-C connector, though the port does not have or need a cover.

So, theoretically, you'd need a port that supports 20Gb/s to run that 16Gb/s speed. Which brings us to USB and Thunderbolt. 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.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. 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. UNIVERSAL COMPATIBILITY UPDATE: Apple has also since released the M2 series of MacBooks, which change nothing with its ports compared to M1 (non-Pro), so still Thunderbolt 3 and USB 4. Lame. 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. Also, we are not discussing the physical port types in this review (Type-C, Type-A). The only thing you need to know is that USB 3.2 Gen 2x2 REQUIRES a USB-C port. So if you have the "fat USB" or Type A ports, it will never exceed 10Gbps.

Haltbarkeit (★★★★★): Die SanDisk Extreme PRO ist stoßfest und robust. Sie hält den Strapazen des täglichen Gebrauchs stand und schützt Ihre Daten zuverlässig. For most practical purposes, USB 3.2 Gen 2 at 10Gb/s is fast enough. I can edit 4-5 streams of 4K 10bit h.264 off of it just fine without proxies or ProRes. But higher-bitrate video, like RAW, 6K, 8K and beyond, I would recommend a faster TB drive. Otherwise, save some money and go with the other SSDs, like the Extreme Portable, or build your own. Though physically small, the SanDisk Extreme Portable SSD is a rugged device and comes with an IP55 rating, the International Protection Rating system that classifies degrees of protection against elements that might intrude into the drive. The specific IP55 rating of the SanDisk drive means that offers protection against dust and potential liquid damage such as the rain and accidental spills. The SSD can also survive drops up to 2 meters. All of these are must-haves for those working outside or those on the go who simply always have the portable drive on them.

Thank you!

Overall a solid drive. But if you have a need for speed, go for a Thunderbolt 3 SSD instead. It will NOT hit the max 2000 MB/s speed. It will max out around the same top speed as the other USB 3.2 Gen 2 drives (1000 MB/s)! Go for the regular extreme pro at a cheaper price, or instead, build your own. However, stay away from the Samsung T7. But I'll save that review for another day.
