YUCUN 2.5 inch SATA III Internal Solid State Drive 1TB SSD

I guess time will tell with this, but at the moment it works perfectly fine.Cheapest new 120gb SSD I could find. Wanted it for a dual booted 2nd Windows OS.Due to the cloud storage and my games being on steam and Uplay my OS drives aren’t that critical anymore as I can have a new one installed and set up in less than an hour. So I’m happy to take the “risk” on an unknown brand.Tested in crystal mark and it goes head to head with my Sandisk Plus 240gb which is a mainstream SSD. See the image. The Yucun benchmark is on the left and the Sandisk on the right.For those who haven’t installed an SSD before, the installation is straight forward. For a desktop, just take out the old drive (2 cables - 1 data, 1 power) whether SSD or HDD and just pop the new one in using the same cables.If you are adding this in as an additional drive you may need to buy a new SATA data cable. Which should only cost a couple of pounds. The two cables will only fit one way round. Also check you have a spare power connector (flat black connector). If you only have a spare white/black moles (with 4 circular holes), you can get a small adapter to convert to SATA power.For a laptop, you usually unscrew a small back cover and then lift up a small “caddy” and take the existing drive out of that and replace, and drop back in. It not very usual for a laptop to enable a 2nd drive to be installed.You can migrate your old OS to the new dive with various free software such as Minitool Partition Wizard Free.120gb is the minimum I would recommend as an only Hard drive. Enough for the OS and basic data. If you are a gamer or have a lot of media content, I’d go higher. With current prices I would start at 500gb as a single dive, but this is still limiting for gaming with many AAA games now exceeding 30-40gb and some over 100gb.

I now have 3 of these at different sizes to use with my Raspberry 400. I initially got one to test but have now started using it as my main drive for rasbian os on my Pi 400. Got faster read and write speeds with this than a couple of others I tried. This led me to getting another couple test with things and one is not set up just playing retro games from. Which is also giving me much fun. I did have a problem with a sata to usb 3 cable but through doing a test identified the cable I got wasn't usap compliant. So if you get one of these drives to use as a external drive get a uasp sata to usb 3 cable to best use the better read write speeds. Ironically the uasp sata to usb3 was the same price as the other on Amazon. So check the specs. Like said got 3 of these now, 1st used for specific operating system use and 2nd games on the other. The 3rd I am using to try other operating systems and things on. (got 1X 120gb use for OS, 1X 128gb general use and 1x 256gb Games).

Half a terabyte is about the minimum I find useful for a C Drive. This product matches my size requirement, and was a good price. I cloned my existing boot disk, then swapped this over, upgrading to the latest version of Windows 10 to be on the safe side. The whole process took a couple of hours - all but about five minutes of this spent by me doing something else.Everything works much faster. And that's about all I can say. Then again, that's about all I really wanted. A few weeks ago, the system that I put together in 2009 failed - a burned-out motherboard. So I spent a few pounds on E-Bay for an Intel DQ67OW, plus i3 CPU. This is old stuff, but much newer than the second-hand stuff I put together a decade ago. The new system was faster than the old, and ran Windows 10 without any of the annoying problems I was having with the old system. I then noticed that the boot disk dated from 2007, and decided that an SSD would make all the difference for speed, and might be less inclined to burn out.And it does make all the difference. For Office 2016, lots of web browsing, and a bit of audio and video cooking, I don't need more than I have, and probably wouldn't notice much difference.Of course, if the disk burns out in the near future, I will come back with a whiny revision to this review. Until then, I will say that the product seems to be excellent value for money. I hope it is. I rather believe it is.

Disk filled up with data copied from my 4 disk RAID.For that purpose it was connected to spare SATA connector of my NAS server.Copying speed while copying from NAS -> 2TB Yucun SSD was confusing.Few video files copied with good speed up to 300MB/s, then next file paused in half, and finally resumed, but average speed for the file was just 100MB/s Since then speed didn't go up never again. Not to the initial level. Maybe sometimes it was better .... up to 150 maybe 180MB/s, but not faster.I didn't think the drive is faulty. Just blamed poor cache performance or something like that.After copying data, I've installed the drive into my new server and everything looked good.The issues started to appear after week or two. Reading speed decreased to 800KB/s, so very slow.After reboot everything was good again.Strange, because other drives didn't have any issues like that, but ignored it as it was just first time.After few days situation occurred again and reset helped just for a while.I was about to return it, but since there was still few days till returns deadline, I've made decision to do another test.This time, I moved the drive to another machine, and since then everything works perfect - no issues at all.I don't know what was wrong. Was it incompatibility or maybe faulty cable, but I must say I was wrong, while wrote my previous review.Of course, one month is not enough to say if it's good or not - specially that drive has been written just once, and since then it's just being read.One star still reduced for poor write performance.
