Do you own a laptop? Are you constantly running out of space to store pictures, music, and movies? Can’t seem to find anything that you put into that computer?
If this sounds like your problem then there is a solution! You could buy an SSD. SSD stands for a solid-state drive. It is a device used for storage much like a USB flash drive or a normal hard drive only much faster, cooler and sexier.
What happens when something is different from other versions in the same series?
For example, there are many versions of SSD’s depending on how much memory they hold and the speed at which they can read and write data. Well, it so happens that SSD’s can be broken down into three major SSD series.
The real question though is which one should you buy?
Do you go for cheap or do you go for expensive? Perhaps expensive gives better results but in this case, we are looking at bang per buck; which one gets the most in terms of quality and performance for what it costs. So in order to figure out which is best we need to look at some numbers: if they cost roughly the same then which is better per dollar?
Tips on What to look for when buying an SSD?
Samsung SSD 840 vs Samsung SSD 850
simply put Samsung SSD 840 and Samsung SSD 850 are virtually identical in terms of everything; they both have sata 3, both use toggle mode flash memory, both come with a three-year warranty and even their read/write speeds are the same (540MB/s Read; 520MBI s Write), there isn’t much of a difference between them save for the fact that this new model has 4 bit per cell NAND interface which is why it costs more.
Samsung SSD 840 pro-SSD has the most memory at 256 GB compared to that of an average Samsung SSD which is roughly half in storage capacity, in comparison to the normal version this variant gives more bang for the buck without sacrificing too much speed in terms of reading/write speeds either since it’s only slightly slower than the other two models.
The rpm’s or revolutions per minute approach when looking at hard drives doesn’t work so well for SSD’s because they lack the physical parts needed to actually spin. Instead, we look at two main aspects: read and write speed, these are measured in MB/s and Samsung SSD 840 pro likes to brag it has a reading speed of 540MB/s and a writing speed of 520MB/s that beats both the Samsung ssd 840 250GB (140MB/s Reading; 260MB/s Write) and Samsung 850 (up to 540MB/s Read; 520MBI s Write).
When it comes to SATA cables there is SATA 1, SATA 2, and SATA 3. Now knowing this won’t be necessary when buying an SSD but SATA 3 is the SATA cable needed to take advantage of ssd speeds which are on average 550MB/s.
Now Samsung SSD 840 pro SSD has SATA 3 built into its design making it compatible with any sata port that you throw at it, Samsung 850, however, does not have SATA 3 so if your motherboard doesn’t support sata 3 then you’re out of luck and will either need to upgrade your motherboard or buy some sort of conversion/adapter.
Flash memory style
Flash memory style refers to how data is stored in memory chips, there are two types of flash storage used by manufacturers: toggle-mode 2.0 and ONFI 2 NAND interface, this basically affects SSD performance and Samsung SSD 840 pro SSD uses toggle-mode which is the faster of the two. On top of this Samsung 850 SSD actually has a four-bit per cell NAND interface hence why it costs more than the Samsung SSD 840 pro version.
SSD’s can be surprisingly heavy compared to regular hard drives, mostly due to the fact that they lack moving parts however some manufacturers will use cheap plastic inside their enclosures meaning that they are correspondingly lighter than their metal counterparts which feel more solid in hand. Of course, this doesn’t matter unless you’re using SSD’s on your laptop where weight does affect portability so do some research before buying if you care about how heavy SSD is in your bag.
7) brand reliability
Buying an SSD from generic manufacturers will not only mean fewer features but also lower quality overall, most generic manufacturers don’t make SSD’s they simply use Samsung or intel chips and package them up with their own enclosures. Samsung for example is very well known for making SSD drives ever since they first introduced sata ssd drives in 2009.
