The Crucial X9 1TB Portable External SSD is a fantastic choice for anyone needing fast and reliable storage. With speeds of up to 1050MB/s, it’s perfect for transferring large files quickly and efficiently. The build quality feels robust and durable, and the performance has been consistently impressive.
One very minor drawback is that it doesn’t come with a USB-C to USB 3.0 adapter. It would have been a nice addition, especially for those who need to connect to older devices. Despite this, the SSD itself performs exceptionally well, and I’m very pleased with its overall functionality.
Excellent, well made and sturdy little piece of lit. Got a 1 TB one sitting behind my Mac Mini M2 2024 model. Runs apps incredibly fast as well as transfer of data. The Mac SSD is around 1,200 MBS speed and this is only a blink of an eye behind it, But bear in mind Apple want 400 for a 1 TGB SSD, not 70…. a tinny trade off to make. Very pleased with it, make sure you use the thunderbolt port though but will also work with USB if you have an adapter, but MAY effect speeds, but not sure. Hope this helps.
An absolutely brilliant and compact-size external SSD. I bought the 2TB model for some extended storage on my PS5, and within minutes of plugging in the USB C-C cable I had most of my games library transferred. This SSD has a lightning fast 1050 Mbps data-transfer rate, and is the amazing small size of a mobile phone battery.
This is my first purchase of a Crucial product, but they seem to be a top-notch American made brand, and I would rate this as highly as my Samsung SSD. Excellent build quality, robust, reliable and a high quality brand. Definitely recommended.
Very happy with this drive
When connected over USB-C using the included cable I was able to get speeds close to the advertised speed. This enables very fast backup/copy of files between my PCs so will save a lot of time.
I noticed some reviews claiming only around 400-500mbps speed – this is likely because the port or cable only supports USB 3.2 Gen 1 speeds (max ~625 megabytes per second) and not a fault of the device
When I ordered this I didn’t realise just how small it is. It’s tiny and it weighs nothing. It’s USB-C so you’re covered for most modern devices and it’s an SSD so it’s fast. It’s not as fast as having an nvme type SSD directly on your motherboard, for sure, but it’s plenty fast enough for my needs.
You can see from my photo just how small this is. I’ve put my Sennheiser earpods next to it to show the scale.
The case is solid and feels very protective, although I’m not going to drop it on purpose to test it! The specs suggests it’s pretty tough and feeling the case I can believe it.
I kind of wish I’d gone for the 2TB or even 4TB version just for future proofing, but the reality is that 1TB is way bigger than I actually need, since I’m not using it for long term storage. I’m transferring around 50gb when I have a working session so there’s absolutely tons of space with the 1TB version.
At this stage I have no way of knowing what the longevity is like, but I’ve had Crucial prodcuts before and always been pleased with them.
Full marks to Crucial for an excellent ssd drive.
USB type C’s primary benefit is speed. Type C connections are significantly faster than USB 3 type A connections. Confusingly, the USB naming system changed a few years back to further confound consumers. The basic USB 3.
0 standard now becomes USB 3.2 gen 1. Take note of the Gen. 1 as this is important in terms of overall speed. The Gen. 1 suffix denotes basic USB 3.0 speeds of up to 5 Gigabits – NOT Giga Bytes – per second. Many get confused over Gigabits and Gigabytes, with the latter perhaps being more familiar to people and thus greatly misleading. So many times I’ve seen and heard people say: “Yeah, it’s a one Gigabyte per second speed.” In fact, in order to work out how many Gigabytes per second one Gigabit is, you divide it by eight. So, one Gigabit = 125 megabytes per second. This is vastly slower than a true one Gigabyte per second, given that traditionally 1 Gigabyte = 1,024 Megabytes. Most determine one Gigabit = 1,000 megabytes per second and that’s close enough to not worry about minor naming scheme differences.
Anyway, traditional USB 3, now USB 3.2 gen 1, tops out at 5 Gigabits per second, or, to put it into perhaps more relatable terms, 625 megabytes per second. However, this speed is unattainable as the USB standard has overheads and other design elements that restricts this speed to close to 3.2 Gigabits max throughput.
Still with me? … Great!
Now, using the traditional USB 3 connection via the supplied adaptor, the very best sustainable transfer speeds I’ve seen are around 225 megabytes/sec, or about a quarter the advertised “up to” speed claim. To be fair, I do not have a USB Type C port to connect the drive to. If I did, I suspect performance would increase significantly. bear in mind that although USB type C ports are now becoming more mainstream, it’s likely you won’t have one if your PC is more than three years or so old. The point of all this is to manage expectations as to the performance of this drive. In daily use using a regular USB 3.0/USB 3.2 gen 1 port, I get about twice the transfer speed of my Seagate 1Tb 2.5inch external hard drive which manages a respectable 120 megabytes/second average transfer speed using Windows 10.
For me, the main reason I went for this drive was it’s low price (just 47 at time of purchase) and the fact it was an SSD, and thus had no moving parts. This meant that it was far more robust as a portable device than a traditional hard drive with its spinning platters.
Yes, it’s faster than the old external hard drive, but using regular USB 3.0 type A connections, it’s no speed demon, so don’t expect it to get anywhere close to the touted performance. Of course, the “up to” phrase so often used in advertising is a best case scenario, so buyer beware if you[re purchasing this solely on it’s speed claims.
Otherwise, this is a nicely built drive, feels solid and weightier than I had thought a solid state drive would be. The only other minus here is the ridiculously short included data cable. I don’t know it’s precise length, but it’s approximately a foot (30cm)at best. My tower case PC sees the drive having to dangle from the front mounted port.
Overall, this is a nice, solid external drive that will outperform any mechanical hard drive at this price point. My unit came pre-installed with two files that were links to web pages to, I assume, download the free software from the likes of Acronis and some photo app that I can’t recall the name of. Useless to me, but there all the same for those interested. I believe there is a third file which linksw you to Crucial.
Finally, the drive comes pre-formatted using the X-FAT file system. This is a highly portable file system that will permit use with Mac or PC. Other devices, such as Android tablets etc, may not be able to access an X-FAT formatted drive. However, the unit can easily be re-formatted using NTFS if needed.
Fast, but nowhere near the claimed speeds for probably the majority of users.
