Hard Disk Sata 2 Vs Sata 3
Ssd sata 2 5 inch.
Hard disk sata 2 vs sata 3. Sata iii revision 3 x interface formally known as sata 6gb s is a third generation sata interface running at 6 0gb s. What does sata stand for. Sata and sas connectors are used to hook up computer components such as hard drives or media drives to motherboards. When purchasing a sata or esata storage device make sure your motherboard s version of sata can handle the version that device has.
Sata 3 communicates at the rate of up to 6 gbit s and its bandwidth throughput is 4 8 gbit s 600mb s which doubles that of sata 2. It is a serial link that makes a point to point connection between various computer devices. Furthermore they are a bit slower in data retrieving as compared to the ssds. The bandwidth throughput which is supported by the interface is up to 600mb s.
Sata 3 also known as sata 6 gbit s is the most recent generation of sata and the full version was released in 2009. All this while consuming just 4 more power than a sata iii ssd. Sata 3 and all sata devices are considered backwards compatible that is if you connected a sata iii hard drive to a computer that has sata ii built in the drive will only operated at the speed of sata ii level. Sata 3 is backward compatible with both sata 1 and sata 2.
This is clearly a win for pcie interface. The bandwidth throughput which is supported by the interface is up to 300mb s. They are less expensive than ssds. The only other difference is minor internal process optimizations.
The performance gap between sata and pcie is quite huge as sata iii maxes out at 6 gbps or 600 mb s. Speedy reliable sas drives are typically used for servers while sata drives are cheaper and used for personal computing. The third type of hard drives is the sata. Sata stands for serial advanced technology attachment.
If you ve an old desktop even a 14 year old motherboard as my good friend has done you can put in an m 2 nvme drive using a pci express adapter. Sas based hard drives are faster and more reliable than sata based hard drives but sata drives have a much larger storage capacity. The electronics on both ends the computer and device differ though. Sata 2 0 provides half the speed of sata 3 0 3gb s to 6gb s respectively.
Pci express to m 2 nvme. And the version 3 was introduced 5 years later in 2009 doubled the transfer rate to 6 0 gbit s a perfect fit for the ssds that started to evolve as the mainstream highspeed storage. Notice it is 5 times the speed of the best hdd s i have. Came with 3 year old lenovo e560 laptop.
In effect you d not get any better performance that you would with a sata ii device and waste your money you paid extra to get sata iii.
