SanDisk 1TB Extreme PRO Portable SSD - Up to 2000MB/s - USB-C, USB 3.2 Gen 2x2, IP65 Water and Dust Resistance, Updated Firmware - External Solid State Drive - SDSSDE81-1T00-G25

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.

I use this (4TB) for backing up everything I need to save, from multiple drives. I've had external HHD's in the past fail and I'd lose everything I hadn't backed up elsewhere. I've been in IT or 39 years and get paranoid about backups and usually have multiples of important data. This SSD is perfect and transfers fast, depending on the source drive of course. It's small and I keep it in a fireproof lock box when not in use. No issues at all.

Awesome storage device. I wanted to get away from traditional external hard drives for large database and cloud backups. There initially was some formatting problems, but a quick search of the Internet said this was a common issue with this specific SSD. Once I went in and name the device And set up its characteristics it worked fine.

small, no noise, and faster Tham any hard drive that I have ever had.I am now operating with 2 of these and no external hard drive.FASTEST transfers that I have ever had.2x4 Terabytes, HOW LONG WILL it take me to use 8 T

Edit:Turns out this is the model that SanDisk is being sued over for being faulty.Buyer beware.Original Review:I bought one of these when it first came out and it works great, although does not achieve its maximum speed on my M1 Mac with Thunderbolt 4. See the review iApplegeek made about this device for more detailed info. What he said is absolutely correct and I have experienced the same.If you need SanDisk, you're better off going with the older "non pro" version of the extreme SSD--it'll achieve the same exact speeds as the new version unless you very specifically have a computer which will do these speeds. Again, M1 Mac does not achieve these speeds over Thunderbolt 4.Now, let's talk about the rest of them that I purchased. I have to reiterate that the FIRST ONE that I purchased is running strong and has zero issues. It sits on my desk and, while warm, it functions as intended.Then there was the second one I purchased... and the third one.... and the fourth one....They worked... until they didn't. Like straight up, units 02-04 all worked one day and then when I woke up, my system said unrecognized disk. Not on any other of my drives which are also all plugged in. Happened on my desktop and my laptop. I returned unit 02 and was replaced with Unit 03. Same result. Unit 04, same result.Luckily, I was smart enough to have a backup of my working files, but had I not.... this could have been catastrophic.A note about the 02-04. 02 was an amazon warehouse deal and I think someone might have returned a used drive (it had scratches on it and the back looked slightly rubbed from going into a laptop pocket or something). Okay, we can let that one slide because I have been seeing an increase in products like this from Amazon, where someone must have returned their old product in a new box... okay... not fine, but fine.What about units 03 & 04? Do we blame this on it being from a 3rd party seller on Amazon and not Amazon.com as seller? Do we call it the same customer fraud switch? Hard to say.I am currently waiting on WD's customer support for unit 04, which has been experiencing massive internal problems from when corporate was hacked a few weeks ago.... okay, fine.... not fine, but fine. I figure, if three units from amazon in a row are bad, let's go direct to MFG for a replacement. Maybe it's the batch Amazon received? Fine, not fine.Soooooo..... yeah.... I'm a video editor and 1/4 units working as intended is a really bad ratio. I think I am going back to Samsung. I have had a T5 for a long time with no issues and just bought a set of 4TB T7.The one unit of this that works, it does work fine and the paint job is prettier than the non pro, of which I also have--no issues with the non pro unit, but I am kind of paranoid to open my back stock of them after all of this.

Probably the best external drive I've tried, sturdy, fast and does not crash.

Gone are the days of bulky and slow drives. This thing is tiny and blazing fast. It transferred over 100GB in 2 minutes. Get it, you won’t regret it.Native Mac and PC apps come pre-installed on the drive.
