Hi
I have a speed problem with Sandisk Extreme Pro usb 3.0.
My System. 4790K OC @ 4.4GHz (permanent), Asus Maximus Hero VII, 16 Gb 2130 ADATA RAM, 500 GB Samsung SSD.
Just purchased this PSSD and tested right away with HD Sentinel and CrystalDiskInfo - both failed, will exchange a drive for SMART failure.
SMART reports
From CrystalDiskInfo
Health Status : Bad (0 %)
E8 __0 100 __5 000000000000 Remaining Life
From HD Sentinel PRO
Failure Predicted - Attribute: 232 Spare Blocks Remaining
Replace hard disk immediately.
The TRIM feature of the SSD is supported and enabled for optimal performance.
It is recommended to backup immediately to prevent data loss.
232,Spare Blocks Remaining,5,0,100,Pre-Failure: Data loss predicted,0,0,Enabled
232 -attribute number.
So I guess I am not lucky this time, so I decided to check the speed, just in case and was surprised by the results
Sequential Read : 44.557 MB/s
Sequential Write : 44.881 MB/s
Random Read 512KB : 42.186 MB/s
Random Write 512KB : 39.549 MB/s
Random Read 4KB (QD=1) : 7.378 MB/s [ 1801.3 IOPS]
Random Write 4KB (QD=1) : 9.854 MB/s [ 2405.8 IOPS]
Random Read 4KB (QD=32) : 8.271 MB/s [ 2019.4 IOPS]
Random Write 4KB (QD=32) : 9.922 MB/s [ 2422.4 IOPS]
Test : 100 MB [N: 0.0% (0.0/119.2 GB)] (x1)
OR
Sequential Read : 44.533 MB/s
Sequential Write : 44.915 MB/s
Random Read 512KB : 42.315 MB/s
Random Write 512KB : 36.576 MB/s
Random Read 4KB (QD=1) : 6.705 MB/s [ 1637.0 IOPS]
Random Write 4KB (QD=1) : 6.864 MB/s [ 1675.8 IOPS]
Random Read 4KB (QD=32) : 6.941 MB/s [ 1694.6 IOPS]
Random Write 4KB (QD=32) : 6.989 MB/s [ 1706.2 IOPS]
Test : 1000 MB [N: 0.0% (0.0/119.2 GB)] (x1)
I did not reformatted yet, as I suppose to return it tomorrow, so it is in Fat32 format as shipped from the store. Label said 260 MB/s READ and 240 MB/s WRITE. I understand that my results can be lower, but not that much lower.
Is this because the drive is failing (SMART) or something else?
Any Ideas or suggestions?
Appreciate in advance for anything.
