Ubuntu Check If File System Is Read Only

I test it and check the file quality is perfect

Only drive I use for my video file backups.

[This review was collected as part of a promotion.] This microphone worked really well right out of the box. I am on a system running Ubuntu and all I had to do was plug it in. No hassle with any software/firmware etc. It just works!

Everything arrived early and was exactly as described. Most impressive was that monitoring software was available for my Ubuntu system. All too often the Linux world is ignored by manufacturers. Kudos to CyberPower. All installed and worked without incident. The only thing that's interesting is that every time I power up my computer the UPS produces a single beep which I presume is its way of telling me that they are talking to each other. Thanks UPS!

Was so happy with the camera u brought a second to use around the cabin to have pictures on file of people snooping around. Only down side is having to purchase a second plan at full price.

I wanted to know the actual Write speed, but didn't get a real world answer. But SanDisk is a GREAT brand (I have several USB drives & Memory cards), so I purchased the 512GB version and tested it myself connecting the USB-C plug to a new Galaxy S22 smartphone with USB-C port. - TEST RESULTS - Transfer of one 2.25GB Video file: Write speed: 43 MB/s Read speed: 100 MB/s - IMPORTANT NOTE: These results might be the optimal since it was ONE large file and the USB Drive was empty (except for that file when reading, so no fragmentation of any kind). With MULTIPLE files, the speed is lower, as on EVERY SSD, HDD, USB Flash Drive and Memory Card. - As every very compact USB drive with two different USB ports on each end that I have used, it gets a bit hot, but so far I never have any problem with any of them. - This one is compact, sturdy and clicks on each USB port position. It also has a hole for carrying. - I am Very happy with my purchase. - If you want faster Read/Write speeds, then an option is to buy Sandisk Extreme Pro SD Card and use an USB Card reader to use it as a USB Flash drive, but total cost is the double of this VERY COMPACT and STURDY USB Drive. Hope this helps other people.

Excellent. Plug and play. Read CFexpress file created by a Nikon D6 to a desk top computer file flawlessly. Great product.

[This review was collected as part of a promotion.] The WD Blue SN570 500 GBis an affordable NVMe SSD for an entry-level build or upgrade. Its interface is PCIe 3.0 x4 NVMe v1.4 with a standard M.2 2280 single side form factor. Transfer speeds are fast for small read and writes but it slows down with large file size transfers. As a test, I wrote and read a 20 gig file. The write speed leveled out to 560 MB/sec at the end of the large file. Read speed ended at about 490 MB/sec. If you want to upgrade the capacity in a pre-built entry-level computer, then this drive is for you. If you are expecting performance beyond average daily tasks, then this SSD could be a bottleneck.

It works well, and no problems for Ubuntu Linux to recognize. :)

Read the reviews.... authors missed the whole point, or are in 'lalaland'. This is an emergency stealth light, or a photographer's light to check camera settings in moon lid darkness when using 'Photopills'.... It will not hurt your eye at 1 lumen, and check all your settings. Personally, this is a great light to be kept in your camera bag. Love the 1 lumen setting!!
