what is sas hdd?

SAS represents Serial Attached (SCSI Stands for Small Computer System Interface, normally articulated as “scuzzy”) and is an innovation for moving information from and to hard drives.

While SAS alludes to the interface it is commonly used to depict a kind of hard drive, generally 10K or 15K SAS.

The higher rates and a more elevated level of strength settle on SAS the conspicuous decision for Enterprise use and in circumstances where fast and dependability are principal.

SAS hard drives come in 2 fundamental sorts: 10K and 15K. The K alludes to the rotational speed of the hard drive, for example 10,000 and 15,000 cycles for every moment separately.

Serials of sas


  • SAS/Serial Attached SCSI Hard Drives 2.5″ SFF and 3.5″ LFF are solely for use in servers that utilization hot swappable (hot-trade) drives with a SAS hot pluggable backplane. You utilize a hard drive plate or caddy or sled, and essentially slide and clasp the crash into the front of your server.
  • SAS/Serial Attached SCSI hard drives are ordinarily utilized in Dell Poweredge Servers T110 II, T310, T320, T410, T420, T610, T620, T630, T710, R220, R310, R320, R415, R420, R420XR, R510, R515, R520, R610, R620, R630, R710, R715, R720, R720XD, R730, R730XD, R810, R815, R820, R910, R920, NX3000 and PowerVault Storage Arrays MD1200, MD3200, MD3200i, MD3800f ; Compaq Proliant® frameworks, for example, DL160 Gen8,DL320e Gen8, DL360e Gen8, DL360p Gen8, DL380e Gen8, DL380p Gen8, DL385p Gen8, ML310e Gen8, ML350e Gen8, ML350p Gen8, SL4540 Gen8, SL4545 Gen8 and Ibm xSeries, for example, 336, x336 and SFF (Small Form Factor) Servers and Storage Systems.
  • Model models are: 400-ANVM, R755K, 400-ANVG, ST3600057SS, ST3300657SS, ST600MM0026, ST1200MM0088, WD4001FYYG, MK2001TRKB, MG03SCA300, ST3600057SS, AL13SXB60EN, ST9300653SS, AL13SEB900, WD9001BKHG, MBF2600RC, ST2000NX0273, MBF2600RC, ST300MP0005, ST900MM0036, ST2000NM0045, AL13SEB600, ST600MM0006, ST1000NM0045, ST9300653SS, AL14SEB120N, ST300MM0008, ST600MP0005, ST900MM0026, ST1000NM0005, AL13SXB30EN, ST1200MM0088, ST4000NM0025, ST600MM0088, ST800FM0043, ST9300603SS, ST33000652SS, ST200FM0053, ST600MP0005, 0F27352, 0F23370, 0F23369, 0F23369, DTK38, C36WJ, 9CDHG, CGC60, G5DM2, D5FMJ, 391KC, J7FYX, 2XT8Y, VT8NC, 6N9HJ .

SAS Speeds

  • As far as speed the best measure is IOPS (Inputs Outputs Per Second) which gauges the information throughput which characterizes the rate at which information can be perused from or kept in touch with the hard drive.
  • A common 10K SAS drive works at around 120 IOPS and 180 IOPS for a 15K SAS Hard Drive. . This thinks about to around 80 IOPS for a 7.2K SATA Hard Drive. Strong State Drives can work at a range between 4,600 to 75,000 IOPS relying upon the sort of SSD.

SAS Capacity


SAS circles can run from 300GB to up to 900GB. They are lower limit than SATA drives yet what they need limit they compensate for as far as speed and dependability.

SAS Reliability

  • SAS hard drives are planned for use for high requesting applications where speed and high accessibility are the essential concerns.
  • SAS drives make some Mean Memories Between Failure (MTBF) that is commonly acknowledged to be around 1.2 million hours. This thinks about to around 700,000 hours for SATA drives and roughly 2 million hours for SSD drives.

SAS Power Consumption


  • SAS drives ordinarily devour between 5 to 7 Watts when inactive and between 10 to 14 Watts in ordinary working conditions.

Points of interest Of SAS Over SATA


  • SAS has a few points of interest of SATA based drives.
  • SAS drives are quicker and have more data transmission throughput than SATA drives. SAS drives are additionally more dependable than SATA.
  • Thus, at last SAS will in general be utilized for Enterprise applications use while SATA is focused on the buyer advertise.
  • In any case, speed and dependability include some major disadvantages and SAS drives don’t have the limit that SATA drives offer and will in general be progressively costly per GB.

specification on amazon

  • This Drive has a SAS interface, the SAS stockpiling design is for servers that request higher data transfer capacity, can’t be associated with SATA backplanes
  • Check controller similarity on SAN, NAS System; These hard drives are planned for big business server and server farm situations, they won’t work in your PC
  • 6 TB inner HDD, 7.2k RPM, 512e arrangement, 3.5 inch structure factor, double interface ports
  • PowerChoice innovation, low halogen, super equality, security data (T10 DIF)
