hey community , i installed the samsung ssd 830 series 256gb in my HP DV7t SE 4100 Notebook computer.
I have confirmed that ACHI , TRIM , NCQ are all enabled, (though i could not confirm AHCI in the bios as those bios options are not available in the HP's INsyde h20 bios) .
However multiple benchmarks with Samsungs Magician software, ATTO , and AS SSD , all show sub quoted read read sequential speeds. samsung quotes 400-500mb/s but i am consistently getting around 220 read and write.
I have contacted samsung and they could not help with the matter. I did a fresh install of windows on the drive before installation. to be fair i'm not sure if the laptop motherboard uses sata3 or sata2, if that even matters, since the drive is backwards compatible.
specs on the SSD drive here, SATA 6Gb/s (Compatible with SATA 3Gb/s and SATA 1.5Gb/s)
Samsung Magician software for SSD management
Samsung Toggle DDR NAND Flash memory
Samsung 3-core MCX Controller
Samsung 256MB DDR2 SDRAM cache memory
Dimension : 100 x 69.85 x 7mm
Sequential Read: Up to 520MB/s
Sequential Write: Up to 400MB/s
Random Read: Up to 80000 IOPS
Random Write: Up to 36000 IOPS
Any help would be reallllllly appreciated . attached screenshots below.
