For $7/month, boost your storage performance by 500*!
*number of input/output operations per second (IOPS) on a HDD: up to 100 IOPS. On an SSD DC S3K: up to 75,000 IOPS for read.
SSDs are definitely the future of storage: they're getting more affordable and offer more storage space than ever before. The lastest generation of SSDs designed for datacentres are now just as reliable as mechanical HDDs, but offer up to 500 times more performance.
Sequential bandwidth (Mb/s)
Hover your mouse over an image for more information.
An SSD can produce 75,000 IOPS (number of input/output operations per second), whereas an HHD can produce just 150.
Where write speed is 115 Mbps for writes on a traditional HDD, it can reach 430 Mbps on an SSD.
SSDs not only have reduced access time; the latency also remains stable, regardless of the load on the SSD. This performance gurantee is a major strength of datacentre SSDs.

Performance consistency and service quality
It is equally important for servers to have consistent performance as it is to have maximum performance. Performance consistency is one of the things that sets apart the consumer SSDs from the SSD datacentre models like those chosen by OVH.
Datacentre SSDs scale well in RAID configurations.
SSDs are physically as reliable as the high-end mechanical disks, with a mean time between failures (MTBF) of 2 million hours. The issue with SSDs concerns their durability, as memory cells only support a limited number of write cycles. But don't panic! SSD controllers check that the data is intact after every write. If it isn't, the data is blocked off and written elsewhere.
This process could potentially reduce the available space and reduce performance, but again the datacentre SSDs have capacitors to guarantee higher availability than what's offered by the consumer models.
Lastly, Intel datacentre SSDs contain Power Loss Imminent (PLI) technology. These SSDs contain capacitors which, in the event of failure, continue to power the electrical circuits to complete any write cycles in progress and to prevent any data corruption.

Hybrid configurations and available options
Even though the cost of SSD storage space is getting lower, mechanical disks are still much cheaper. To give you the best of both worlds, OVH also offers hybrid servers: 2 SSDs for performance needs (database, frequently read data, etc.) and 2 HDDs for sufficient storage space (backups, logs, etc.).

Technologies and features
While classic hard drives are made of magnetic bands and steered by a mechanical arm, solid-state drives (SSDs) are only made of flash memory chips, which speed up the drives significantly.
