For read speed speed and cost per Gb, this 6Tb one is a better deal: https://www.amazon.com/dp/B0F3368QFL

6 TB likely has a QLC drive and this 4 TB Pro has a TLC drive inside. Crucial doesn't specify the drive inside the X10 (non-Pro), but they do specify for x9 Pro drive. And the higher speed is only for PCs equipped with USB 3.2 gen 2x2 ports and not for regular 3.2 ports and that speed is not supported on ANY of the Macs.

I've found that if a return or exchange is needed, Amazon has a 30-day period without a restocking fee, while Best Buy has a 15-day period with a restocking fee.

Price per TB is lower. However this metric ignores TLC on the X9 Pro versus (likely) QLC on the X10 non-Pro. In the past, the main differentiator between the Pro and non-Pro lines was TLC versus QLC, so I would assume this holds true on newer drives as well. I have a 4TB X10 Pro myself, and it's the bee's knees for full disk backups of internal NVME drives. When it comes to sustained writes, the X10 Pro is about twice as fast as the X9 Pro. At the time I was buying, the price difference was only $20, so it was a no-brainer to go with the faster drive.

If you don't care about speed a hard drive is better for longevity. I use HDs for backup since I can just leave it backing up in the background.
Please stop spreading misinformation. HDD is much more unreliable than SSD.

The SSD drive's FW is much more complicated than that in HDD drives, several magnitude more perhaps. Bugs ,and inefficiencies and testing challenges therefore. So they can die simply when the FW hits a bug or otherwise gets into a jam. An SSD drive is more in the FW than the hardware NAND itself. There are far more SSD FW developing companies/groups than the controller developing companies. I think there are big differences between them, in terms of quality and performance, that are not apparent to the consumer.

The wearing of the NAND cells, and FW wear leveling solutions, e.g., are an inherent problem in SSDs, worse going to TLC and QLC. Since NAND is erased/programed only in huge blocks, if you use the drive to near capacity then the performance, i.e., the FW's ability to handle wear leveling, paging, buffering, error corrections etc gets drastically reduced. A cliff in fact. So some consumers might think something is wrong with their drive after only a few month, if they use the drive past a certain percentage of the compacity.

So just from the FW complexity and reliability point of view, if someone says SSDs are less reliable than the much simpler and consistent HDD, I wouldn't know if I should agree, but I certainly wouldn't argue with that.

HDD speed is indeed fine for me (even 5400 rpm 2.5" drives), but I also want some external drives that are more robust towards bumps, and can be moved around while plugged in. Hence SSDs.
yeah then do SSDs, just remember to keep them powered regularly - if unpowered for a year or two they can lose data.

I don't know about this - maybe crucial had a bad batch go out and the current one's on sale now are good, but the reviews on B&H about the drive failing after a short time of use are appalling:

here's a few:

Completely unreliable
ByJoe N. 6/29/2025
Verified Buyer
Capacity:4TBPreformatted for:Windows, Mac & Linux

Drive works for a while, then won't get recognized when plugged in. Either won't mount or ejects randomly. Crucial customer service was useless and suggested reformatting in various formats, nothing worked. Same issues over and over. I've only been using it as a 3rd copy backup drive, but I might as well not consider it a backup because it simply does not consistently reliably work. Avoid this drive at all costs. Because of the lack of support or accountability, I'm never buying Crucial again after years of using their gear.

Died within 1 week

Power died within 1 week of using this drive. I know it was a power failure because the LED wouldn't turn on. Tried multiple different cables, plugging into different computers. Lost 12+ hrs of work, learned two lessons: 1) back up projects every few hrs to multiple drives, 2) don't try to save money on storage devices

Bought this drive a couple of months ago to use for photo backups. The drive now spontaneously ejects itself from my iMac. Ridiculous waste of money.

Drive Failed after only 3 months of light use

This drive failed after very little use. Neither B&H nor Crucial would give me a refund. Customer service rep at Crucial said that there have been many problems with this batch of drives.

Failed

Our company bought several of these drives for audio and video use. The size and speed were the big factors for us. Unfortunately, all of the drives have failed a very short time. Contacting Crucial for warranty service was less than good. Will not buy crucial SSD drives again due to quality and service. Replaced them all with Samsung T7 &9's and very happy with those.

Failed in Less than a Year (But Failed Kindly)
ByTy 3/24/2025

Capacity:4TBPreformatted for:Windows, Mac & Linux

I bought this SSD less than a year ago and it has already failed. I really liked this drive & it's form factor, but that is an outrageous lifespan. I've never had a HDD disk fail sooner than 8 years old and my whole reason for investing in SSD was for better longevity of data storage.

That said, I decided to give it an extra star because instead of failing outright at first, it just became read-only. Which is a life-saver. After backing up all of my data, I will be trying to deal with the warranty process I guess!

DO NOT DO IT TO YOURSELF
ByAndy 3/19/2025

Drive purchased November 2024. Drive corrupted March 2025.

Contacted the manufacturer (Crucial/Micron) and they refuse to issue a refund.

I've used LaCie, Samsung and Seagate for 20+ years without any problems and will continue to do so from now on.

More complicated does not equate with less reliable. SSDs have a finite number of write cycles, but also a lower annualized failure rate.
HDDs have mechanical moving parts which will fail - it's only a matter of when - though can last longer when not in constant use, as will most appliances.

You can always buy and return this one if a better deal comes up.
