Indlela Yokufunda / Ukubhala Ukukhawuleza ihluke phakathi kwama-SSD kunye nee-HDD
Ukufunda / ukubhala ngesivinini kuyimilinganiselo yentsebenzo kwisixhobo sokugcina. Uvavanyo lunokwenziwa kuzo zonke iindidi zazo, njengengxowankulu yeckiki yangaphakathi kunye yangaphandle , i-drive-state-drives , indawo yokugcina indawo kunye ne- USB flash drive .
Xa uhlola isantya sokufunda, unquma ukuba kuthatha ixesha elide ukuvula (funda) into evela kwisixhobo. Ijubane lokubhala lichasene - kuthatha ixesha elide ukugcina (bhala) into kwisixhobo.
Indlela yokuvavanya ukufunda / ukubhala ukukhawuleza
I-CrystalDiskMark yinkqubo ye- freeware ye-Windows eyenza ukuvavanya nokufunda kwejubane lokuqhuba kwangaphakathi nangaphandle. Unokukhetha ubukhulu besintu phakathi kwe-500 MB kunye no-32 GB, ukusebenzisa idatha engahleliweyo okanye i-zeros, kunye nokuqhuba ukuqhuba kunye nenani lezithuba ezimele zenziwe (ezingaphezulu kwesinye zinikeza iziphumo ezingaphezulu).
I-ATTO I-Disk Benchmark kunye ne- HD Tune zizinye izixhobo eziphathekayo zamahhala ezingabonakaliyo ezingakhangela i-hard drive yokufunda nokubhala isivinini.
Funda kwaye ubhale ukukhawuleza kubhalwe ngokubhaliweyo ngeeta "ps" ekupheleni komlinganiselo. Umzekelo, isixhobo esinesivinini sokubhala esingu-32 MBps sithetha ukuba singayibhalela i-32 MB (i- megabytes ) yedatha rhoqo ngesibini.
Ukuba ufuna ukuguqula MB ukuya kwiKhi okanye enye iyunithi, ungangena kwi-equation kwi-Google njengale: 15.8 MBps kwi-KBps .
SSD vs HDD
Ngamafutshane, ulawulo olusisigxina lusebenza ngokukhawuleza kokufunda nokubhala ngokukhawuleza, ukukhupha i-disk drive.
Nazi ezinye ze-SSD ezikhawulezayo kunye nokufunda kwazo nokubhala amanqaku:
Samsung 850 Pro:
- Amandla okufumaneka: 128 GB - 1 TB
- Isixhobo: I- SATA III 6 Gbps
- 550 MB / s ukufunda (256 GB)
- 520 MB / s bhala (256 GB)
ISanDisk Extreme Pro:
- Amandla okufumaneka: 240 GB - 960 GB
- Umsebenzisi: SATA 3-6 Gbps
- 550 MB / s ukufunda
- 520 MB / s bhala
Umtshi weMushkin:
- Amandla okufumaneka: 240 GB - 960 GB
- 565 MB / s ukufunda
- 550 MB / s bhala
Corsair Neutron XT:
- Amandla okufumaneka: 240 GB - 960 GB
- 560 MB / s ukufunda
- 540 MB / s bhala
I-disk yama-hard disk yaqala ukuqaliswa yi-IBM ngo-1956. I-HDD isebenzisa i-magnetism ukugcina idatha kwisitya esijikelezayo. Intloko yokufunda / ebhaliweyo ifaka ngaphezulu kwesitya sokufunda nokubhala idatha. Ngokukhawuleza isitya sihlawulela, i-HDD iyakwenza ngokukhawuleza.
Ii-HDD zithe gqolo kunezi-SDD, ngeqondo lokufunda eliphakathi kwe-128 MB / s kunye nesantya sokubhala esingu-120 MB / s. Nangona kunjalo, ngelixa i-HDD ihamba ngokukhawuleza, ayabizi, kwakhona. Iindleko zi malunga ne-$ .03 ngegigabyte ngokubhekiselele kwi-$ ephakathi .20 ngegigabyte yama-SSD.
