Toshiba Memory America Toshiba OCZ TR200 Series 2.5" SATA III 240GB Internal Solid State Drive (THN-TR20Z2400U8(CS) 2.5"

I ordered this to replace an old conked off HDD that came built in with Lenovo Flex 3 1580. Surprisingly, the built in Western Digital HDD just lasted a little over a year. Now I'm happy that it only lasted that long as this new Toshiba SSD is pretty awesome and has helped speed up the machine, significantly. I wonder why Lenovo chose to install an HDD versus SSD on a machine that has a good processor, 8 GB RAM etc.etc. It is probably because a 1 TB HDD may be cheaper than a 240 GB SSD but 240 GB is good enough for me.

I love it! It took a little long the shipping, but it totally worth it. My laptop runs incredibly faster than before (I was about to give up with all the repairs trying to get it faster), but this was the solution. 100% recommend if you have an old computer and don't want to throw it yet.

Pros: Professional reviews indicate this drive is relatively low performing. I've found this often is not accurate because they trust synthetic tests. My test for this drive on Mint 18.3 and a Z270 i5-7400 platform, was to create a 6GB RAM_Disk and transfer 5.5GB of mixed files to the SSD, which used Ext4. The speed was 9 seconds. My best high end drives gave 8 seconds. The boot time from boot menu is 10 seconds to desktop, which is exactly the same as my high dollar SSDs. Shutdown times are the same. The great thing about OCZ/Toshiba drives is the bootable toolbox allowing total independence from Windows. This GUI Toolbox also runs flawlessly on most Linux Distros. As good as they truly are, you don't have to wonder about Smartmon tools or Gsmartcontrol for accurate SMART information, and can do a firmware update online. Trim checked by: [sudo hdparm -I /dev/sda | grep TRIM] Gives "Data Set Management TRIM supported (limit 8 blocks)" but not "Deterministic Zeros after TRIM."Cons: The endurance rating at 60TB is just okay, not impressive. Still, with normal use that's several years of use.These drives Trim time is very slow compared to some other brands. Even with Mint 19x which has enhanced Trim compared to Mint 18x. As an example, a clean install with all updates and 8GB apps, takes 2.2 minutes, with Btrfs as root or Ext4 as root. With normal use and once weekly automatic Trim, the time increases somewhat as weeks go by. Other, (but certainly not all) drives I have with 3D Nand Trim in 10-30 seconds. This drive is the slowest Trimming of all I own or have tested. It is not a deal breaker, but I find it annoying. With Windows 10 these drives Trim rapidly.

I ordered this SSD for my mother's laptop and it installed great I was able to clone her old HD to the new SSD without any issues. It boots up very fast and loads programs in a snap! I would recommend this drive and would buy higher a capacity for my desktop
