That day when quality met performance and performance met price.
I’m rebuilding a Dell E6440 and the DVD drive was wearing out. So, I opted for an additional drive, instead. This SSD fits inside of a caddy sold on Amazon. The hardware installation was straightforward. But I’m not a professional so I waited until my Wife got home. She’s a Computer Science Grad. For her it was easy to set up. And it works great. Very fast file transfer speed. And very reliable. It’s a Kingston product, and Kingston products are very high quality. The price is a bargain. I highly recommend this Kingston SSD.

What a difference, wish I’d bought it sooner
A laptop I was losing my patience with went from being “some old something I’ll use in a pinch” to “I can’t stop carrying this around the house with me” with one upgrade.I’d find some chores to do if I needed to reboot…it took some 3-4 minutes. Now it reboots in less than 30 seconds.Have to install a program? Oh crud, I better get comfortable, this is going to be awhile. Now its nearly as fast as my gaming desktop.There is no comparison…this 8-year old laptop I bought off of Craigslist with a 17″ screen was just for watching movies in the bedroom…its all it was good for. Now its a fully functional laptop with a brand new lease on life and that I plan on having for years to come, if it holds up.What a good price for such an impressive upgrade…very, very happy that I decided to try this out. I will absolutely report back if it goes bad anytime soon, but as of now my inner geek is celebrating getting what seems like a brand new PC. Can’t recommend enough.

If you need internal SATA this drive is great.
Works perfectly. I replaced my old hard drive with this internal SATA SSD. My laptop doesn’t support NVMe, but this fit in the hard drive’s slot. I wasn’t supposed to be able to run Windows 11, and the hard drive was awful. With this SSD it runs fine! I also put Linux in separate partitions, and totally happy with this arrangement.

Better for external than internal
It’s not the fastest or most durable, but it’s cheap.Better SSDs have a small chunk of DRAM to run file location functions while operating. DRAM is faster temporary memory which can handle loads of read/writes without wearing out.This SSD does that directly on the flash storage. It’s a cheaper way to build a drive, but slower and can wear out the memory just like if you re-wrote files constantly.It actually works out OK, but not a great choice for an internal drive in a high-use machine (especially a mini server). It’s worth buying something better for machines you really care about long term.However, it’s perfectly fine for backups and transfers. And plenty reliable if you want to turn an older laptop into a travel device or terminal.Check specs and tests if you do look for something better, rather than comparing star ratings directly. Most people probably buy this for the low-intensity purposes I suggested, so it gets rated appropriately high. Good SSDs made for harder professional use will have similar overall ratings after being subjected to much harsher use than a backup drive which spends most of its life powered off.

Had some hesitation initially buying this Kingston A400 480 GB SSD ( 2.5 Inch ). Finally it arrived next day and used in a USB 3 Enclosure. Performs fast at consistent speed of around 105 MBs for large file transfers. Considering the price, this a great performance. The casing is metallic finish and feels good. Will recomend this for people loking for performance at affordable price. There will be more faster drives, but few seconds will not make that great difference. TIP: In USB Enclosure, right click properties – Policies -and enable Disk Caching to improve data transfer. It makes a very big difference. Just remember to click to Safely Remove drive option if this is enabled.
