Bit of background: there seems to be two types of SSD's around: SLC and MLC, with SLC being the faster type. AS MLC is less than half the cost of the other type, and that this is for a mainly web-browsing notebook, i went with the cheap MLC... 32GB MLC Now i've been using it for a while, i'm trying to work out if the drive is just incredibly slow or theres some sort of incompatibility with the chipset, as the speed difference is silly... Now here is the weird part: if the HDD usage is low, the speed is great! if the HDD usage is high, the drive seems to get overloaded and bogged down to a crawl. One example: vista > vista SP1 on the original SATA 5400rpm HDD = ~2hours vista > vista SP1 on the SSD HDD = overnight (gave up watching after 5hours, though being solid state this wasn't a problem as it made no noise ) after being sat on the desktop and the usage going to idle, the system is as similarly fast on both loading desktop apps, eg firefox any burst of constant high HDD usage will get the HDD LED stuck on permanently lit + massive slowdown for some reason with XP it was unusable... with vista and a 2GB dedicated readyboost SD card it's great (apart from a slightly long initial boot time) Seems readyboost is the only factor here, without it it's constant crawl like XP in ubuntu it was fine as well (well it will be when i get around to fixing the power management/sleep/hibernate settings, but the speed was fine) Laptop is a rebadged one of these with a 1.2ghz ULV core duo, 2GB ram and now a 32GB SSD HDTach of relevant SSD and SD card on the laptop: Speeds aren't brilliant, but much better than RL performance suggests. All that said, it has had amazing effects on battery life, i can easily get 4-5 hours out of it now anything obviously wrong here? or working as it should for a budget SSD?
The figures your getting are pretty much spot on for the drives specs, as follows: Model : TS32GSSD25S-M Read (KB/s) : 26003 Write (KB/s) : 13566 Random Read (KB/s) : 25296 Random Write(KB/s) : 2518 Source: http://www.dustinhome.se/FetchAttachedDocument.aspx?ProdID=5010118406
sorry about not being relevant to the thread but assuming your lappy is the Philips 11NB5800 i was wondering how much battery life you tend to get out of it in real world usage...
Nothing really concrete as yet, as i tend to plug the power in when it gets to 20%, but certainly seems good for well over 3+ hours at that percentage batt life. i'll see if i can get a better battery life estimate at the weekend
If your laptop has sufficient RAM try setting the TMP-file to something really low like 256MB and see if it helps. Also perhaps try defragmenting the drive so you get more sequential reads. Otherwise than that I'd say you've made a cheap but poor choice on SSD. If readyboost is able to speed things up dramatically then something is wrong with the speed of your ssd
Check if Windows has enabled the slower PIO transfer mode instead of the normal DMA, because that will cause HDD (in this case SSD) slowdown. (However, IIRC that would be like ~3-4 MB/s, but check that to be sure.)
checked that one, is set okay... still seems to be the wierd bug where if there is a certain period of constant hdd usage the drive will bog down and slow to a crawl* (HDD LED constantly lit + nothing happening)... Whereas if the drive does something from idle, it's really fast overall though, the longer i leave it, the faster it gets... i'm assuming this is the readyboost feature kicking in now significantly *car analogy: travelling 0-50 mph/h gets you there at that speed travel somewhere at 50 mp/h for more than 30secs, you get slowed to 10m/ph untill the engine idles again
Is that dip at 16.1 GB normal for an SSD? Because I saw those on a laptop hard drive I had which when installed on the laptop would cause immense slowdowns at various points. Once replaced, the lappy was back to its good old speedy self. Of course this was not SSD so I am unsure if those dips matter in your case.
The write speed on that drive is appalling. Model : TS32GSSD25S-M Read (KB/s) : 26003 Write (KB/s) : 13566 Random Read (KB/s) : 25296 Random Write(KB/s) : 2518 If you do anything it will slow down. You can help it by turning off anything that may use the HDD; Indexing Automatic De-frag System Restore If you have lots of ram, reduce the pagefile size. If not, get more RAM.
