Make your computer faster with a SSD drive

Generally we keep upgrading our computers to the latest processors but at the most you might just see around 20-25% overall performance boost even with the latest processor compared to your 2-3 year old processor because the main bottleneck in our modern computers is the slow IO operations due to the physical nature of the disk that we use particular the Hard Disk (HDD), the HDD are very slow compared to the memory and the processors and thus everything slows down due to the same 90% of the times the CPU would be just waiting for the data to arrive from the HDD so upgrading to a faster HDD technology makes a lot of sense and hence SSD (Solid state drives) come into the picture.

Think of SSD as huge blocks of Memory Chips that store your data the data does not get wiped even when power is not there, comparing it to traditional HDD as there is no moving head that is required to physically move from one location to another to access the data, the seek times are very fast on a SSD upto 50 times faster than HDD.

SDD Drive Memory Chips

But sustained SSD read and write speeds are not that fast but still they are around 2.5 – 4 times faster than HDD so loading of lot of flies like booting a computer or launching of applications all happen a lot faster typically 2x – 3x time less compared to standard HDD now compare the performance boost that you get by just having a powerful processor the application might just launch 30% faster but now with the help of SDD you are getting a boost of around 200 – 300% which needless to say is pretty impressive.

For example a normal 3.5 inch HDD with a 7,200 rpm which is found in most desktop computer can get in real world around 55-65 MB/sec of transfer speed using SATA interface but even cheap SSD have a transfer speed of around 200 – 250 MB/sec and the newer faster SATA 3 ones can go around 450 Mbps (OCZ Vertex 3) which is needless to say very fast when compared to traditional HDD.

The other thing is that SSD are virtually silent as there are no moving parts in them and that in turn reduces the heat produced by them also in terms of power consumption they beat the traditional HDD most SSD consume just around 2 watts of power when active and even less in standby mode.

There is always a flip side to the latest technology and it’s no different with SSD, the main problem with SSD is the cost they are expensive when you compare them to traditional HDD for example a SATA2 60 GB SSD would cost you around Rs 6,500 whereas you can get more than 2 Terabyte (2000 GB) standard HDD for around Rs 5,000 so in terms of raw storage space a traditional HDD beats SSD hands down.

Thus the ideal way to use a SDD is to just load the Operating system and your frequently used programs on that and use a traditional HDD to store all your data like Music / Documents / Media thus in this way you get best of both the worlds your system will boot and perform a lot faster and genreally most of applications will launch 2-3 times faster compared to a standard HDD and thus even a 60 – 80 GB SSD would be sufficient, in Windows doing this is very simple just make the SSD your primary ‘C’ boot drive and load the operating system on that and you can have a traditional HDD as your secondary drive where you store all your other large data / media files.

    The hard disk drive (HDD) is responsible only for read and write speeds and the load time of applications NOT the processor speed….So HDDs do not bottle neck say, the processing speeds of an i5 or i7….

    But yes your absolutely right about everything else!

    PS: Loved the video you posted on beam tele speedtest!

    Bhaskar…. yeah a SSD is like a HDD is responsible only for read and write but it speeds up everything.

    I personally have the latest i7 computer with a normal HDD and a Core2duo Laptop Macbook Air with a SSD and the laptop feel a lot faster than the i7 while booting and launching heavy programs so overall using a SSD will speed up everything as I said IO operations is the bottle neck generally so overall your system will appear to be a lot faster with the SSD drive.

    My friend also recently made a i3 desktop but he put a SSD 120GB on the boot drive and while working on his system I get the feeling it is faster than my i7 system in generic usage, yeah in heavy computing task like rendering or video encoding etc my i7 beats the crap out of that i3 machine but overall response of your system improves drastically with a SSD.

    hi Ranjeeth this is uday kiran i was worried about purchasing a laptop n i was a developer of web apps need a good laptop having a 4GB ram or 8GB , 500GB hard drive,and having a small doubt that going to core i5 or i7 because am a big fan of PC games tooo kindly suggest me a laptop of range below 55000/- kindly waiting 4 ur suggestions thanks 4 your great stuff which am tracking on ur videos am loving it

    For mobile Sandy Bridge processor things change a bit the i7 is 4 core and hyper-threading enabled and the i5 are dual-core and hyper-threading enabled so keep that in mind also some of the ultra low voltages i7 and i5 chips are just dual core for example i7-2649M, i7-2629M, i7-2657M, i7-2617M, i5-2537M all are dual core but support hyper-threading…. so make sure which chip are you getting….. 4 GB should be good enough unless you are planing to do video editing or run Virtual machines.

    See my video on i5 vs i7 for gaming http://www.youtube.com/watch?v=R0xsEnP6yWA but remember that video was made for desktop chips.

    I am not a laptop guy a desktop person and feel for gaming laptops are a bad choice…. anyways for gaming get the best GPU you can, cannot give you specific models coz Its been a while since I have checked the new windows laptops.
