Customer Ratings & Reviews

There's been issues with this drive since a week after I bought it. It keeps disconnecting itself, stopping my workflow and forcing a restart. I have several of the same drive that work fine (purchased from other stores than best buy) but this one in particular is faulty and I haven't had the time/don't want to deal with the headache of getting a refund and also having to move like 3 tb of files that I need for active projects :/

Sandish Extreme Portable eHDD is not very responsive. I am not happy with the speed even though it is SSD. Will evaluate as I use and see. Online reviews were not encouraging.

Drive became unreadable on my Macbook months ago. It wouldn't load. Sandisk provided a firmware update to correct the problem, but it has a note: "Critical: Ensure to create and verify a backup of all critical data to another location or device before updating the firmware on any drive. " How does one back up the disk before updating, and how does one update the disk if you can't load it on a Mac? The update that SanDisk provided must be implemented using a PC, specifically "on a Windows 10 or 11 computer". How does that work? You bother your friends with a PC or go to a tech support station at Best Buy or elsewhere to do this, costing money, and perhaps losing some files. I can go on or you can read the Ars Technica article: "SanDisk's Silence Deafens as High-Profile Users Say Extreme SSDs Still Broken"

Bought this so could download more than 20 years of data (primarily photos) stored on old hard drives. It’s been a pleasure and highly recommend.

We have spent thousands on Sandisk and been loyal customers of their memory cards and drives until now. They knew these had probelms and continued selling them. The first one i received didnt work frim the beginning. They sent a replacement and I uploaded almost 4tb of my kids’ pictures and other things and it has sat on a shelf for months until i needed to access the pictures only to find it doesnt work!! Dont use this to backup anything important.

It never worked. It spontaneously ejects itself. Didn’t realize it didn’t come with Best Buy Protection so Best Buy wouldn’t help me. The company did allow a replacement but it’s much easier with BB protection.

Buyer beware, this 4TB SSD is prone to corrupt out of the blue and become unmountable. It would disconnect randomly while the mac was on standby and then the files would be corrupted after. Went through 3 rounds of severe data loss with no backups as the backup was also on a sandisk that corrupted. Extremely disappointed in the brand after being a WD user. This product is should be recalled

I just got the product. But haven't use it long enough to give a good or bad yet for the price that i paid for over $300++ But I'd like to give a feed back on customer service onside, I bought the product online for pickup in store. I got the product, a few days later the price when down, I went to the same store I had pickup the product and tried to do the price match, I use credit card to purchase this product, but close the account. At the return counter I asked for store credit instead the lady told me I only have one option which is put it back to my credit card even I told her, the credit card close. I end up with called Best buy customer service and they told me I can do store credit, I went back to the store again, this time they told me they can do store credit, but unfortunately the product was pass 14 days after purchase, can't get store credit. So I overpaid due to lack of knowledge from Best buy.

Purchased a 2TB ScanDisk SSD, which worked well after one year of use. Purchased this 4TB ScanDisk SSD on 12/31/22, and it crashed the first time on 2/28/23, and now again on 4/19/23; lost all of it’s data both times. I have lost tons of GoPro volleyball videos that were taken for my daughter’s college recruiting efforts. I DO NOT RECOMMEND THIS PRODUCT!!!

Could be better very disappointed. I would never recommend this external hard drive

Love it! Could connect to my Samsung TV no problems and its light weight!

I like this 4TB External USB but latest article about the failure of this drive is disapointing

SanDisk Pro keeps abruptly failing. 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. This happened just days after using it. Search it online and you will see how common this issue is...

Constantly has wiped my data 4 different times this is uncalled for I have read multiple reviews on this product as well this is a defective item there are class action lawsuits being pursued on this issue as well I want a full refund have been trying to get a full refund for the past 2 months and still nothing.

Be careful with this product, don’t keep importan data because is very unstable, sometimes disconnects without any reason , I have some friend who had lose data and not able to recover anything with this drive.

Cost is the only reason for four stars product amazing

This is the worst ssd I’ve ever had to deal with. If you are a Mac user, don’t purchase this trash ssd. It’s not compatible. Randomly deletes data and unmounts itself. You can’t re mount it no matter what without reformatting and losing all your data. I thought I had a defect but the second replacement has the same issues. This is not Mac compatible

Do not purchase. Device will fail and you may loose date. Luckily I was able to return within my purchase window. The device will unmount or eject automatically and at random making it difficult to depend upon. If device is being accessed during this period, you may loose data.

Mine only lasted a year. Now I can’t write anything to it.

If there was negative stars that's what this would get along with Sandisk. Bought these 4 months ago and they started failing to mount. Of course there is no support in store and the RMA process from Sandisk has been proving to be a nightmare of no responses and "under review" for who knows how long. I really loved this products of this brand but lately it has gone down hill. Junk Junk Junk.
