Disques SSD NVMe™ à forte intensité de lecture pour entreprises

La série KIOXIA CM7-R se réfère aux disques SSD à forte intensité de lecture optimisés pour supporter une large gamme d’applications et autres charges de travail associées destinées aux entreprises incluant la Business Intelligence (BI), le traitement transactionnel en ligne, le stockage défini par logiciel et la virtualisation. Basés sur les technologies PCIe® 5.0 et NVMe™ 2.0, les disques SSD de la série CM7 offrent une performance excellente jusqu’à 2,7 M IOPS (lecture aléatoire) et 310 KIOPS (écriture aléatoire).

Dotés de la mémoire flash BiCS FLASH™ 3D TLC 112 couches de KIOXIA, les disques SSD de la série CM7-R d’entreprise NVMe™ présentent une endurance de 1 DWPD (Drive Writes Per Day) et supportent des capacités de stockage allant jusqu’à 15,36 To, ce qui les rend particulièrement attractifs pour les applications d’entreprise exigeant une forte intensité de lecture.

  • Definition of capacity: KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1 GB = 2^30 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
  • GT/s: Giga Transfers per second.
  • A kibibyte (KiB) means 2^10, or 1,024 bytes.
  • MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTTF.
  • DWPD: Drive Writes Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day for the specified lifetime. Actual results may vary due to system configuration, usage and other factors.
  • Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions.
  • IOPS: Input Output Per Second (or the number of I/O operations per second).
  • Temperature (operating): Specified by the composite temperature reported by SMART.
  • [1] Sanitize Instant Erase (SIE), Self-Encrypting Drive (SED) and FIPS (Federal Information Processing Standards) SED security optional models are available.
  • [2] SIE optional model supports Crypto Erase, which is a standardized feature defined by the technical committees (SCSI) of INCITS (the InterNational Committee for Information Technology Standards).
  • [3] SED optional model supports TCG Opal and Ruby SSCs. It has a few unsupported features of TCG Opal SSC. For more details, please make inquiries through “Contact us”.
  • [4] FIPS SED optional model utilizes a security module designed to comply with FIPS 140-3, which defines security requirements for cryptographic module by NIST (National Institute of Standards and Technology). For the latest validation status, please make inquiries through “Contact us”.
  • [5] Security optional models are not available in all countries due to export and local regulations.
