Sunday 27th July 2014: 5.52pm. I forgot to post my annual SSD vs magnetic hard drive capacity per inflation adjusted dollar graph which I updated in May, so here it is. The trend of deexponentialisation of SSD capacity per dollar growth has continued as I first predicted in 2012 (http://www.nedprod.com/studystuff/SSDsVsHardDrives_201204.png), and currently SSDs are growing slower than magnetic storage which implies they will never catch up in terms of capacity per dollar.
Thursday 16th August 2012: 1.00am. So, here's what a #Sandforce 1200 #SSD on SATA II looks like against a #Samsung 830 SSD also on SATA II (same PC, an old 2.67Ghz Core 2 Quad with dual channel PC2-6400 RAM). The 830 clearly slams hard into the 3Gbps max speed of SATA II - seeing as it can max out SATA III this is no surprise. The #SF-1200 has broken TRIM support so at that time of testing I hadn't figured out how to hack the registry to work around it, so write speed was a pathetic ~60Mb/sec, but it could get itself up to 120Mb/sec or so with TRIM working.
Wednesday 15th August 2012: 10.59pm. Courtesy of my shiny new 256Gb #Samsung 830 #ssd replacing that #POS #Sandforce SSD 60Gb boot drive which died, I have the space to install Linux alongside Windows for the first time in some years. I've always been a #KDE man personally, I find it's close enough to Windows I don't have to think too hard, so I fired on a copy of #Kubuntu 12.
Wednesday 15th August 2012: 5.36pm. Interestingly the #Samsung 830 #ssd in my cloud node hit a write cycle count of 50 today, and with its 25ns flash that's 1% down 99% to go. The 830 gives a fair few stats actually, so the SSD has been powered on for 2500 hours and has written 2.679Tb which makes an average of about 1.1Gb/hour or 26.26Gb/day. The only concern I've ever had with this SSD is a UDMA CRC error count of 23925, but when I replaced the SATA cable it seems to have stopped increasing so it's all good.
Thursday 9th August 2012: 9.35pm. Looks like my +Corsair #Force #SSD boot drive (based on the infamously crap #Sandforce #SF-1200 chipset) really is truly dead. Last time it died I was able to resurrect it with a Secure ATA erase i.e. hard factory reset, but this time it's completely unresponsive to anything and appears to lock up during device initialisation. Thankfully, given it had hosed my Windows 7 install twice before, I had nothing important on it, but it's still irritating and inconvenient.

Link shared: http://www.behardware.com/articles/862-1/components-returns-rates-6.html As I need to configure a ZFS software RAID-Z redundant storage pool for my cloud before I emigrate to Canada (i.e. buy a new 3Tb hard drive), I was very pleased to find a hardware vendor that publishes the return rates of the products it sells which is very, very rare anywhere on the internet. Turns out those 2nd gen Sandforce SSDs are seeing a 10-15% return rate which is astronomical, and it's not like that technology is remotely new yet they keep fobbing off consumers with SSDs that just don't work.
