KIOXIA CM7-R 3.84TB NVMe GEN5 U.3 15MM SSD KCMYXRUG3T84

SSD

SSDs using SATA, SAS, or NVMe interfaces are ideal for applications where the balance between read/write speed and affordability is important. They can be used, for example, as system disks, in database server,s or IOPS-heavy hot-storage. In addition to its unrivalled speed, it offers, at a higher price, very low failure rates and higher reliability and resistance to vibration and temperature fluctuations. These drives are generally available in 2.5" format, and they are therefore compatible with hot-swap slots designed for HDDs.

Speed

For SSDs, speed is most commonly divided into sequential speed, which is given in MB/s, and random speed, which is given in IOPS. SSDs are many times faster than traditional hard drives and are rapidly approached in price in recent years. They also have a much lower access time and they do not wear out the disk during the reading process as is the case with traditional rotating disks.

Speed Read/Write
14000/6750 Mbps
Random Read (4K) Random Entry (4K):
2700000/310000 IOPS

Capacity

The capacity of a disk often determines its usage. High-capacity HDDs are used for storing and backing up large amounts of data. High-capacity SSDs are useful, for example, when multiple users are simultaneously working with large amounts of data in real time. On the other hand, SSDs with a small storage space are mainly used for the operating system and its fast running, or as a boot drive or hypervisor.

Lifespan

To determine the lifespan of the drive, TBW(TeraBytes Written) and PBW(PetaBytes Written) parameters are often given to indicate the total data written to the SSD before failure. The second most common designation is DWPD (Drive Writes per Day), indicating how many times per day the user can overwrite the entire capacity of the SSD for the duration of the warranty.

2.5“

This format is most often found in SSDs, but also in desktop, most often laptop hard drives, and also specialized fast SAS drives. It stands out with its lower consumption and better heat dissipation compared to 3.5" disks. The most common use is found in 1U and 2U servers, all-flash disk arrays.
