When I built my new machine I went with a SSD as I figured it would quicker than a mechcanial one. My supplier only had Apacer SSD, so I picked up one of those. I must admit I didn't really know too much about the drive before I purchased and I certainly didn't know much about read/write speeds and the deal with smaller/larger files.
While the sequential read/write are in line with the advertised specs, the 4k write speed is very slow. They are about 1/2 the speed of my WD mechanical drive. Have I just picked up a repackaged older SSD? I know they had a lot of problem with writing small files.
Apacer Pro II AS202 64 GB
Spec on the box
Sustained read/write (MB/s) 210/110
Crystal Disk Mark 3.0.1
5 passes at 100MB
Read/Write (MB/s)
Seq 215.5 89.58
512k 191.2 53.94
4k 17.04 1.275
4k QD32 19.03 1.302
I don't know if this is pertinent to this thread, but the drive also has issues booting from a cold start. The OS resides on the SSD. It registers as a "?+serial number" in the bios after being turned off for a while. Holding the power button in for 20 seconds seems to reset the state of the drive and I can boot again. I tried swopping the power connector, position on the m/b, SATA cables, hard drive delay. For the first time this morning, I ripped out my WD My Book Essential external drive and the boot up seemed up quicker and without issues. Could my external drive be preventing the bios from reading the SSD?
