Leej twg, yog tias tsis yog cov neeg ua haujlwm ntawm cov chaw kho mob, paub tag nrho cov yam ntxwv ntawm kev ua haujlwm ntawm SSD tsav. Yog li ntawd, tus editor ntawm "MacRadar" coj lub xov tooj thiab hu rau ob peb lub chaw los ntawm kaum saum toj kawg nkaus ntawm Google. Nyob rau hauv tus txheej txheem ntawm kev tham nrog tus tswv, peb tau tswj los tsim peb txoj cai yooj yim rau kev siv SSDs.
Txoj cai 25 feem pua
Txoj cai ib: tawm 25% ntawm SSD tsav khoob. Piv txwv li, koj yuav 120 gigabyte SSD. Txog 10 gigabytes yuav mus rau OS, lwm 25 gigabytes yuav tsum nyob twj ywm. Peb tau txais 82.5 gigabytes. Qhov no yog qhov chaw disk uas peb tuaj yeem siv tau. Zoo heev, puas yog? Peb yuav 120 gigabyte disk, tab sis peb tsuas siv tau 82, 5. Qhov no piav qhia li cas?
"Yog hais tias lub disk yog tag nrho cov ntaub ntawv, piv txwv li, tsos, suab paj nruag thiab sab laug dawb, hais tias, 5-10 gigabytes, ces lub disk yuav pib "nplua", - hais tias. Nikita Provotorov los ntawm ON-PC.ru tuam txhab. - Qhov no tshwm sim nrog cov disks ntawm ib lub tuam txhab: INTEL, Silicon Power, ADATA thiab lwm yam. Yog li, nws raug pom zoo kom tawm 15-25% ntawm qhov chaw disk dawb."
"Txoj cai 25% tuaj yeem suav tias muaj txiaj ntsig zoo," hais tias tus kws tshaj lij Lavxias cov ntaub ntawv rov qab tau zoo. Ilya Seidel … - Qhov siab dua qhov sau thiab sau dua tus nqi ntawm SSD, qhov chaw khoob yuav tsum tau tso tseg. Qhov tseem ceeb tshaj, zam dhau qhov cua sov ntawm SSDs. Qhov kev cia siab ntawm flash nco txo nrog nce kub. SSD maub los siv qhov ntawd rau hauv tus account, tab sis vim li cas thiaj ua rau lub neej nyuaj rau nws? Thiab, tau kawg, tsis tas yuav khaws cov ntaub ntawv nquag hloov kho hauv hom pib ntawm SSD, piv txwv li, 1C databases. Yog tias qhov no yog qhov tsim nyog yuav tsum tau ua, tom qab ntawd nqa PRO-chav kawm disc thiab tshawb xyuas qhov ntim txhua hnub nrog cov chaw tsim khoom tshwj xeeb. Ces qhov lav yuav siv tau."
Qhov kev poob qis hauv qhov nrawm ntawm qhov puv puv SSD disk yog vim qhov peculiarity ntawm lub cim xeeb hlwb. Txhua qhov thaiv cov ntaub ntawv yog 512 kilobytes, thiab muaj peev xwm ua tau, piv txwv li, tsuas yog ib nplooj ntawv ntawm 4 kilobytes loj. Tab sis nyob rau hauv rooj plaub no, tag nrho cov ntaub ntawv thaiv yuav raug suav hais tias yog nyob. Tsis zoo li HDD, uas cov ntaub ntawv tshiab tuaj yeem muab ntxiv rau cov uas twb muaj lawm lossis sau dua cov qub, cov ntaub ntawv hauv SSD yog thawj zaug nyeem thiab tom qab ntawd sau dua tshiab. Qhov no ua rau kev ua haujlwm qeeb qeeb. Txhawm rau tswj hwm qhov ceev ntawm SSD, koj yuav tsum tsis tu ncua "tshem cov khib nyiab" ntawm nws, thiab rau qhov no muaj TRIM muaj nuj nqi.
TRIM Txoj Cai
Cov hlwb ntawm SSD-disk tau sau nrog cov ntaub ntawv thaiv thiab yuav tsum tau ntxuav ua ntej ua ntej sau cov ntaub ntawv tshiab. Ib qho tshwj xeeb TRIM hais kom ua qhia rau SSD maub los tias cov ntaub ntawv hauv qee lub hlwb tau raug tshem tawm los ntawm tus neeg siv thiab tsis xav tau ntxiv lawm. Thaum lub sij hawm ncua, tus maub los yuav tshem tawm cov hlwb ua ntej, uas yog, nws tsuas yog "tshem tawm cov khib nyiab" ntawm cov ntaub ntawv. Qhov no muaj txiaj ntsig zoo rau kev ceev ntawm kev tsav tsheb thiab nws txoj sia. Qhov tseeb OS X 10.10.4 hloov tshiab ntxiv TRIM kev txhawb nqa hauv peb tog SSDs. Txhawm rau pab nws, nkag mus rau sudo trimforce pab kom cov lus txib hauv Terminal thiab rov pib lub computer. TRIM tau qhib.
Txoj cai thaub qab
"Rov qab cov ntaub ntawv los ntawm SSD yog tus qauv nyob ntawm thiab tsis tas yuav ua tau," hais Valery Dorogavtsev los ntawm MHDD.ru. - Yog tias SandForce 3 maub los tau teeb tsa rau ntawm disk - thiab cov no yog cov qauv tshiab ntawm Intel, OCZ, Kingston disks - ces peb tuaj yeem hais nrog qhov tseeb tias cov ntaub ntawv los ntawm lawv tsis tuaj yeem rov qab tau."
"99.99% ntawm cov disks ntawm SandForce maub los tsis tuaj yeem rov qab tau," hais ntxiv Vlad Barkhaev los ntawm DATARC tuam txhab. "Thiab yog tias koj siv disks ntawm Marvell maub los, piv txwv li, los ntawm Plextor, feem ntau koj tuaj yeem rov qab tau cov ntaub ntawv."
"SandForce controllers siv hardware encryption," piav qhia Pavel Horuzhy los ntawm lub tuam txhab FixInfo.- Hauv txoj kev xav, txhua qhov encryption tuaj yeem tawg, tab sis vim nws siv 256-ntsis tus yuam sij, tus nqi ntawm kev tawg yog siab heev. Tias yog vim li cas lawv hais tias nws tsis tuaj yeem rov qab tau cov ntaub ntawv los ntawm SSD disk”.
"Qhov yooj yim tshaj plaws kom rov qab tau cov ntaub ntawv khaws tseg," qhia meej Nikita Provotorov … - Qhov tseeb yog tias thaum tsim ib qho archive, rov qab code yog sau, thiab yav tom ntej, siv lub archiver, koj tuaj yeem kho qhov yuam kev nrog tsawg poob ntawm cov ntaub ntawv ntim.
Thiab nyob rau hauv xaus - qhov kev pom zoo ntawm tag nrho cov kev soj ntsuam kev pab cuam chaw masters: nco ntsoov ua ib tug thaub qab. Tsis zoo li HDDs, uas tuaj yeem siv sijhawm ntev kom tuag, SSDs tawg sai sai thiab mus tas li.
