SSD slow write speeds

Why is my Kingston Hyper-X Fury 240GB SSD so darn slow? It's advertised as being 500mb/sec sequential write. Something is clearly wrong

I currently have 2x128GB MSATAs in RAID 0 configuration as the OS drive and the Kingston is sat in the 2.5" SATA III port.



edit: ATTO shows different results?

 

How full is the drive?

What is a typical usage scenario for it?

See:
Kingston HyperX Fury 240GB SSD Review - Page 12


From the above link:

Look at the above link - is this a case of nand parts being switched?


Either way, this is an entry level SSD and 'up to' performance (as shown by the uselessly outdated ATTO that most manufacturers stick to because of the high 'scores' it provides) is just that: a way out for manufacturers to leave you hanging.


Curious if you can give these benchmarks a try:

Read speeds dropping dramatically on older files; benchmarks needed to confirm affected SSDs

Specifically, this file: https://mega.co.nz/#!NEYjwIbT!3fdCXNfKzIcfAtrOGxe_Y3NtL56XvGsEJ9NHlyHYusk

I can't find a link for FileBench.zip, but it is should be somewhere in this thread (and I think v6 is the latest):

See:
Samsung 840 EVO read speed drops on old-written data in the drive


Yes, these two programs test for read speed on existing data by file creation date (but I'm curious if any other SSD's are affected other than the Samsung EVO and original Samsung 840 (both TLC) drives.

 

Isn't the Fury a Sandforce 2281 drive? Those speeds look about right for uncompressible data.

 

AshK,

Good catch. I forgot that aspect of SF based drives for a moment.


Cakefish,

Try running the CrystalDiskMark benchmark with both compressible and uncompressible test data to see the scores jump.


See:
Download Center - Crystal Dew World

 

Those were my thoughts as well. The difference between compressible and incompressible can be quite large.

The benchmark isn't the fastest I've seen for SF-2281 drives, but it's around what I'd expect for incompressible data nonetheless. See the two benchmarks with incompressible and compressible side by side if you want to have an idea of the difference.
