Neat Works fine for me, and it saw all 5 of my drives... This is actually a really useful iteration of the "-Z" line of programs. I'm impressed! I'm using Windows 7.
Nice program, no problems here on my side, neither on that rig from my specs (Intel 520 series 120GB SATA3 SSD on Transcend PCIEx SATA3/USB3.0 combo card, Hitachi 640GB HDD...) on Win7 Ult.x64 SP1 or on any other gaming or HTPC rig in my house. thanks for heads up!
Hmm just loaded this up on my OCZ Vertex 4 (512gb) and ran the benchmark figures seem kinda low .. 9.87mb/sec on the 512b sequential read. 59.72mb/sec on the 4k sequential read. 224.11 mb/sec on the 128k read. 23.55 mb/sec on the 4k random read 3.8 mb/sec on the random access time. The IOPs seem nothing to write home about either .. i know this is an older drive but does this seem right ??? windows 7 64 bit and 5 ghz 4820k.
Really low numbers indeed, try AS SSD Benchmark and if it also reports low read/write numbers then I would start panicking.
Looks pretty good for SSDs, but it need to have the info that pops up for HDD taken out. One of my Seagate HDDs shows that I have almost 4,000 PetaBytes written to it. The other HDDs I have also show stupid high write amounts.
I got the same message on a Dell Optiplex with a Samsung 850, but worked after running it as Administrator
This is where benchmarks are usefull - i had gradually become used to this slower speed and the bench highlighted the issue .. due to it benching low i did a bit of hunting and even though SSD-Z said the drive was on SATA III and ACS-2 , it was actually on a 3G port on my motherboard. I changed it to a 6G port and its about 10+ % up on most of the metrics in SSD-Z with a whopping 64% higher on the 128 kb sequential read (367 MB/sec) vs 224 MB/sec before on the 3G port. It still seems kinda slow for a vertex 4 512 gb , but it an old install of windows 7 also.
What % of the drive is in use? I have a Vertex 4 and benchmarks become HORRIBLE when the drive is past 60% full.
SSD-z Reports all wrong for my machine. I recently moved to a new workstation: Intel NUC i7 system with Intel Iris Graphics 16 GB Ram Samsung 950 500GB NVMe SSD Drive Western Digital 1tb Red for storage Machine runs great and the OS (Win10Pro/64bit) reports that Trim is on, also the driver for Win10 from Samsung is installed in the OS. SSD-z shows all kinds of wackyness! No trim Interface Unknown SMART not supported
