SSD Slow Speed

Casterina · 24 Oct 2015 at 12:35

I've the 120GB Samsung 840 Series SSD with latest firmware (DXT09B0Q) and 1TB Seagate Barracuda 7200RPM HDD however the SSD write speed seems to be slower than the HDD which isn't normal?

Both drives is connected to SATA 3 6Gb/s port on my Gigabyte Z77 D3H motherboard.

Try atto benchmark

Is it the 840 non evo ssd? Installed latest Intel rapid storage drivers?

Yes, it's the 840 without EVO and in Device Manager under IDE ATA/ATAPI Controllers, there is Intel C216 Chipset Family SATA AHCI Controller - 1E02

try atto benchmark

you should be seeing around 250mb write on that drive

Installed Intel rapid storage drivers? Find them on gigabyte website

Those writes aren't right

its weird idk what it could be

how full is the drive and any partitions on it? tested with another sata cable and port?

Dervious · 24 Oct 2015 at 21:51

There's nothing weird about this.

Looks like it's an 840 (non EVO) with old data.

Samsung haven't fixed these drives, and they suffer similar performance degradation to the EVOs.

I`ve "refreshed" a few 840s to restore their performance. 6 months later, they'll be slowing down again.

wazza300 · 25 Oct 2015 at 15:11

its probably that then,only way to fix it would be to clone to a spare hdd,secure erase the ssd and clone the data back to it

but it would still degrade performance wise over time
