As SSDs makes their way to dominate the existence of optical HDD technology, we’ve seen so many variations in terms of storage sizes and efficiency but one thing is certain among this innovative storage technology, it’s still very expensive and that’s the reason why it’s found more in smaller capacities.
Talking about SSD sizes, the world’s largest SSD just showed up – it’s the Nimbus Data’s ExaDrive DC100 and it is a 100TB solid state drive, is packed up in a familiar 3.5” SATA drive form factor. Last year, Nimbus Data launched a 50TB version.
According to the manufacturers, the focus of this new drive is efficiency and not speed. So you know what you are opting for if you are interested in it.
The two things it prides itself on is that it is power efficient (0.1W/TB) and space efficient too.
With this SSD, data centers are sure to reduce their spending on electricity, cooling and rack space by 85%, compared to other large SSDs (like Samsung’s 30.72TB SSD).
The drive uses 3D NAND technology that enables storing for 20 million songs, 20,000 HD movies, or 2,000 iPhones worth of data.
Nimbus estimates that the total cost (drive and all) over a 5-year period will be 42% less per terabyte compared to such drives.
The ExaDrive DC100 comes with a 5-year “unlimited endurance guarantee” and has a mean time between failures of 2.5 million hours
Nimbus also mentioned that there are embedded capacitors to protect buffered data in case of a sudden power loss, also the drive has encryption, multiple ECC processors, and a proprietary secure-erase feature to ensure data security.
As stated earlier, the drive isn’t as fast as it’s competition, it has symmetrical sequential read/write performance of 500MB/s and random read/write of 100K IOPS.
This means that it has a better random write than Samsung, but slower read (it does 400K/50K).
The sequential read and write speeds are quite a bit behind though (Samsung’s drive promises 2,100MB/s and 1,700MB/s respectively).
