535 series 240 GB slower speed compared to intel advertise specifications ? a new VW case ?

DB7 — Wed, 07 Oct 2015 14:53:44 GMT

Hello,

I test/benchmark my SSD with AS SSD , UserBenchMark and CrystalDiskMark. In all cases my sequential write speed is about 240 MB/s, insted of 490 as advertised by Intel.

Firmware is RG21, SSD is connected to a intel 6GB/s SATA port as AHCI in Windows 7 64b.

Am i doing smtg wrong or intel has same marketingo as VW ?

Thanks

1. System specs?

2. Is the drive new or long in use?

3. What SSD Toolbox shows about drive health (screenshot welcome)?

Hi, DrBL:

Your 535 SSD speed is just same with Spec, if you read 535 Spec carefully, there are 2 different spec: Compressible & Incompressible. Normally both AS-SSD & CDM use Incompressible data to test, that's why the write performance is only around 220MB/s.

In AS SSD, you can click "Compression-Benchmank" under "Tools" menu, to check the performance again

You can find full 535 Spec here: http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ssd-535-spec.pdf http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ssd-535-spec.pdf
