Is my Samsung 850 EVO 120GB slow ?

vikbot · Sep 21, 2015

On benchmarks it's returning around 450-530mb/s read write score which is nice but when I'm opening program on task manager I see the read speed is around 15-30mb/s. Also program installation speed is not as good as it should be on a SSD. Now is it normal ? What can I do to make it fast ?

Specs -
i5-4690K
Gigabyte GA-Z97M-D3H
16GB RAM
Windows 8.1 Pro

Update - SSD is connect on AHCI mode

SSDs with smaller capacities and also with TLC cells are inherently more easily to become slow once the usage is increased or more capacity is used up. While SSDs are usually very fast, it seems like the smaller SSD with TLC cells is the weak link of your system. I recommend to upgrade to a 512GB SSD with MLC technology like Crucial MX200 or BX100. I pesonally don't buy any TLC craps made by any manufacturers for the sake of getting the highest profit margins out of consumers. MLC SSDs may be slightly more expensive, they are much more durable, reliable, and faster once the drive is saturated with data and access.

What is TCL and MLC ?

Did you clone over to the SSD or was it a clean install of the OS?

What SATA controller driver do you have installed?

Palorim12 :

No, it was a clean install and I don't have any SATA controller driver installed. I think windows has one built-in.

From your motherboard manufacture driver page for your board (http://www.gigabyte.com/products/product-page.aspx?pid=4970#dl):

Please install Microsoft .NET Framework 4.5 first.

To discuss MLC vs TLC, one may also want to understand SLC. Below is a comparison.

SLC (Single Level Cell) NAND was the original NAND architecture and still is made today due to its much higher endurance over the MLC and TLC NAND discussed later. A SLC NAND cell has only two states - a high or a low. For this reason it's the simplest to set to a certain state and the retrieve the content since it can only be a 0 or 1.

MLC (Multi Level Cell) NAND was invented to double the amount of data stored in the same area of silicon on the wafer. This significantly lowers the cost of storing data on a MLC component versus a SLC part. The tradeoff for the lower cost of MLC NAND is less reliability and 10-20 times less endurance cycles (the number of times you can erase/write to the NAND cell).

TLC (Tri Level Cell) NAND takes the MLC concept one step further. By creating more states in the memory cell, you can effectively store 3 bits per cell. Again, the tradeoff is significantly less endurance/write cycles and less reliability than even the MLC components. See figure below.

The lower cost of TLC is great for the consumer market where writes are limited, but TLC should not be used in any applications running Operating Systems, storing mission critical data or most OEM applications.

How do you feel about Intel and toshiba trying to make QLC?
