SanDisk Professional 4TB PRO-Blade SSD Mag - Portable & Modular NVMe SSD Mag, Ultra-Durable - SDPM1NS-004T-GBAND

so far so great, works well with very fast speeds, its bigger than I expected but its high quality and comes with everything needed other than the drives.

Incredible, versatile, small, lightweight, fast. Great pairing for my Kondor Blue grip + hub rig for my iPhone 16 Pro filmmaking jobs.

I got 3 SanDisk Pro Blade 4T and one Pro Blade Transport, totaling about $1000, because I've heard great things about them, and I needed a storage solution. I installed them fine, with no problems. I loaded them up with everything I needed backups of, and the next day, NOTHING...... No matter what I do, none of them will work. They won't show up on my disk utility, and they won't show up in Finder. Macbook M3 Pro. I get that things happen, but I really got pissed when I called Sandisk. Absolutely zero help at all. I could barely understand them, and they couldn't offer any solutions other than sending them ALL in for warranty, or I could buy another transport to see if that is what is at fault. So frustrating, I dont have the words.......I am happy to change my rating if and when I get a solution for these $1000 paperweights. Also, when I went on the SanDisk page to register them, none of the serials were recognized with Sandisk, and I purchased them from the Sandisk shop on Amazon.

This wasn't mentioned anywhere (it took a lot of digging to figure it out, and the lack of information about it is why I took a star off) but the blades (drives) come pre-formatted with APFS, the Apple File System.I found out the hard way when I plugged it into my Windows computer and it didn't recognize it.Thankfully, I'm somewhat tech savvy and have a MacBook Pro, so I was able to reformat the partition on the disk to exFAT, which supports large files and can be used on both a Mac and a Windows computer.Not everybody may be that fortunate.Western Digital / Sandisk, this is a huge issue and you need to either be more up-front about it, offer an easy way for users to reformat the disk for NTFS or exFAT - or even better, sell different versions of the blades that come pre-formatted with the format of choice.And if this was "up-front" clear (not buried in tech specifications) and I just missed it, please point it out and I'll edit this review.EDIT: I'm returning the drive. It refused to format in either exFAT or NTFS so it's of no use to me.

I've been using my Sandic problade for about a year now and it's been awesome. I like the interchangeable storage design.I initially purchased the pro blade so I could use it with my Lumix s5m2x and record directly to an SSD but have since been using it for mass storage in general. I like being able to organize projects physically by drive. The pro blade has become my recording and mass storage systemIts a but expensive to buy into the ecosystem which is what will probably turn most people off but the convenience is worth it for me.

Very reliable. I use the "Blade" for storage, and retrieving of photos while tethering a photo session. Along with a Sandisk desk top hard drive, it's my go to system.

The blade/stick solution is certainly a clever design. After so many formats now gone, the main question is the life span and consequently availability of this format in the next several years. The desk multi-blade boxes are currently too expensive where this system may not gain enough popularity to be still offered i.e. 5 years from now. The stick/blades commend premium cost which cal also limit its market life cycle. Cost reduction and 8TB, 12TB introductions could help.Update 09/26. The 4TB mag I just received via Amazon was unsealed and appeared to be previously used. Not sure wether or not to return it..Update 10/09/24. The SanDisk blade ecosystem could use a dual-bay reader in addition to the too expensive and too bulky 4-bay unit. A raid provision could be added as well.

I bought two of these for two of my offices and both have the same dumb flaw -- they overheat and turn off if you transfer from one high speed drive/disk to another. It's ridiculous that the device doesn't just slow down transfer speed. Instead, it'll just turn off and you have to restart your computer.However, I will say that if you're not transferring high speed files, the drive works well (especially for video editing). But I really hate that for the price, it shuts down if it gets too hot. Kinda ridiculous given the price...
