bought in December 2014, to run Linux Mint system. now showing significant slow down in May 2015.
Disappointed Samsung pout out something like this. I though I was playing it safe sticking to this brand.
Although SSD prices have dropped they still cost a lot of money so now I have to call Amazon to see if I can get a refund ...
Firmware = EXT0CB6Q,
hdparm -t
Timing buffered disk reads: 310 MB in 3.01 seconds = 103.04 MB/sec
Compare to my magnetic HD :
Timing buffered disk reads: 440 MB in 3.00 seconds = 146.64 MB/sec
UPDATE: Speeds continued to drop as low as 12MB/sec , I tried to apply the lastest firmware EXT0DB6Q but it would not run from the Samsung DOS ISO.
The firmware would exit with a kernel32 error. I had to build a new ISO with a more recent version of FreeDOS, before it would run the update.
I'm now getting 215 MB/sec via SATA II in IDE mode which is about the correct speed for Sata II (old mobo Asus P5Q -
I potentially get 250MB/sec in SATA II AHCI mode but sometimes it doesnt mount correctly?)
My vague understanding is that the new firmware does periodic refresh of the data to keep access fast but a downside is that it adds to the write cycles?
I'll leave at one star though because if I could go back in time, I wouldn't touch this SSD for the price.
