An absolute must if you require true sustained large capacity speeds
TL;DR: This drive personally verified capable of large, sustained reads for hours if needed and had no problem transferring 500GB+ of data (both read and write) without slowing down at all. If you’re tired of external SSDs that slow down due to cache outs and/or overheating, this drive will take care of those issues.——-I’ve gone through several Samsung and Crucial external SSDs and one common thing is they all “cache out” sooner than later or even overheat and transfer speeds quickly plummet (sub 50-75MB/sec in some instances) when you’re doing large (>100GB) transfers or if you’re using the drive as an attached active media for real time use like using a replicated database or photo editing. If the job ends up R/W > 75-100GB+ I will always see drive slow downs consistently on those Samsung and Crucial models. They are good for small, quick transfers especially sub 25GB but anything remotely large and sustained and the slowdown happens.After doing a lot of research and reading along with personal recommendation from some fellow developers and editors, I gave the SanDisk 2TB Extreme PRO (you know it’s serious when “PRO” is all in caps) a try.It is very compact and nicely built. Excellent external texture with even a corner clip hole. It comes with both USB-A and USB-C USB 3.2 2×2 cables and is ready for data transfers up to 2000MB/s.So how did it fair? I plugged it into my 1000MB/s rated USB-C port to backup over 500GB of data in one sitting and sat there and watched it transfer the entire set of data with zero slowdowns sometimes peaking OVER 1000MB/sec on large contiguous data asset transfers. This is a first among the pile of external drives I’ve used over the last 10 years.When it came time to copy the information back, the sustained speeds were still there during the entire transfer.I used it even to run some games for testing and it had no problems for Steam or Blizzard games albeit for normal use I use internal storage. I also did a couple of dev projects externally and it worked absolutely fantastic.As with most external drives, it does get warm during heavy use but nothing that is worrisome. I was able to pick up and hold the drive no problem.I tested it on both Windows 10 and 11 and Windows 11 is slightly slower than Windows 10 in data transfers under the same conditions but still peaked over 900MB/sec. It isn’t the Sandisk’s fault but the OS.Overall, I can’t recommend this drive highly enough. It fixed all the issues I had grown used to accepting with my previous Samsung and Crucial models with expected slowdowns (it wasn’t an issue of “if” but “when”) and 2TB is spacious enough for now. If I end up needing more capacity I will pick up the 4TB version if needed but as for the 2TB model specifically? Highly recommended.5/5

Sandisk Extreme Pro Portable SSD 2 TB New Generation
Right now, the only computer equipment that I have is an ASUS 15 inch Vivobook Laptop PC. My desktop self destructed and I gave my Dell laptop to my daughter.Compared to similar portable SSD’s, I was impressed by how durable this Sandisk SSD is (water resistant & dust resistant and survives ordinary drops). I have not dropped it or placed it in water (yet) but it is nice to know that this Sandisk will survive through harsh conditions.I read several negative reviews about how super HOT this SSD gets. So I decided to purchase the Sandisk Extreme Pro Portable SSD 2 TB New Generation (which is a lot more SSD than I really need). Why? The SanDisk Extreme PRO® Portable SSD is housed in a forged aluminum chassis that also acts as a heatsink, saving you time through higher sustained speeds (it is less likely to overheat). The Extreme Pro is slightly larger than the regular Extreme – which also helps it to dissipate heat (although both models are very portable). In other words, this model promises to never slow down due to overheating. In my experience: My Extreme Pro NEVER gets hot, in fact, it seldom gets warm. My Extreme Pro is cool to the touch except the rare times when it is slightly warm. Note: I am not extremely demanding. I read and write small files to my Sandisk from time to to time during the day. Otherwise, I leave the Sandisk plugged to my ASUS laptop all dayOne thing I noticed about my Sandisk Extreme Pro. If there is zero read-write activity for an extended period, my Extreme Pro goes to sleep. And it drops to room temperature. This situation can prevail for minutes or 24-7 with my setup. My Extreme Pro Portable NEVER gets hot. As you read other reviews by other buyers, it appears (I am guessing here) that some users are in a situation where their Extreme Pro or Extreme never goes to sleep (and their device gets SUPER HOT). In my situation, if I attempt to write to my Extreme Pro after it has not experienced any read-write activity for an extended period, it takes a moment to “wake-up” my Extreme Pro. Not a problem because I know this feature allows my Extreme Pro to stay nice and cool (resulting in a longer life). I have not read anything about this feature. If you are interested in how this “sleep” feature works or if your Sandisk portable SSD gets SUPER HOT, contact Sandisk and ask for further details.I did encounter one problem. I have no idea what causes this and neither does Sandisk Technical Support. When I connect this device to the single USB C port in my laptop, Windows OS cannot “see” this SSD. Yet, my PC works just fine with another external HDD that I connect to this same USB C port. So, I connect my Sandisk to a Type A USB 3.0 port (and the Sandisk works just fine). I do not have another PC to connect my Sandisk SSD to (which might give me a clue what is going on). It is entirely possible that something is strange with the USB C port on my laptop, so I cannot blame the Sandisk SSD.This is a revision written weeks later: I purchased a new laptop. Exactly the same kind as I already had, a ASUS Vivobook 15.6″ laptop. Because I really like the keyboard on the ASUS. The USB C port on my new laptop works just fine with my Sandisk Extreme Pro SSD. So the problem lies with my older ASUS Vivobook (read above). My Sandisk Extreme Pro SSD works perfectly.I am happy with my Sandisk Extreme Pro Portable SSD 2 TB New Generation and I intend to keep it long after my ASUS Vivobooks die.My only negative: I wish the Sandisk Extreme Pro Portable SSD had an activity light (so I could tell [at a glance] when it is reading-writing). Note that this device is totally silent and warm to the touch, so not always obvious when it is reading-writing data. Not a big enough negative for me to deduct a star.update: 8 months after purchase. My Sandisk Extreme Pro performing well, going strong. Zero problems. Connected to my ASUS laptop all the time using the USB C port, a laptop I use about 12 hours a day, my Extreme Pro gets warm but not hot.

Portable, durable and fast – but watch out for the 4TB model
Doesn’t get much more portable than these, unless stooping to a thumb drive; even has a hole to put it on a keychain. Used to use thumb drives, but these SSDs are much faster.After deleting included software (some sort of security stuff, perhaps for password protection), was left with 1.8TB, which seems about right for a 2TB drive (somehow, that’s just how the math works with these things).Put it through its paces backing up a TB worth of PC data and copying over some stuff from thumb drives (all at the same time) and it never broke a sweat or had any problem. It gets warm when really busy, but cools right back down. I often leave it connected all day.At under $300, don’t imagine I’ll ever go back to thumb drives. Fingers crossed that it will last, but it seems very durable, supposedly able to withstand water, dust, drops, etc. Not going to test any of those claims. :)UPDATE: I never had a problem leaving the 2TB model plugged in to the PC for weeks on end, but the 4TB model (have tried a few of them) periodically stops reading and Windows 10 complains that the device is “not ready”. Have tried USB 3.0, 2.0 with A connectors, with and without a hub. The only “fix” I’ve found for this issue is to unplug it and put it back, which sucks. 🙁

Great, Fast, I had one issue with it,,I have added some files on it.. after a while when I connect it, the windows didn’t recognize it and I had to format it and loose all my files that I don’t have backup on them ):Make sure when formatting to choose File system: ExFat not NTSF so that it could work on both PC and Mac

Super content de mon achat, disque très compacte qui s’emporte partout.J’ai pris le modèle 4To à 2000Mo/s. Après un test les résultats sont assez bon. Notez que ça chauffe pas mal et par conséquent le disque ne peut pas tenir 2Go/s très longtemps si le transfert est très long.

Haven’t had many chances to test the capabilities of the SSD, but, so far its performance is quite impressive. Turning on its encryption was also straightforward. I heard many news in the past if its data integrity issues but I hope SanDisk has fixed it and it wouldn’t happen down the road.
