Nrog rau kev teeb tsa kom raug, koj tuaj yeem khau raj los ntawm NVME SSD tsav txawm nyob rau hauv cov laus. Nws tau xav tias lub operating system (OS) tuaj yeem ua haujlwm nrog NVME SSD. Kuv tab tom xav txog kev thauj khoom OS, txij li nrog cov tsav tsheb muaj nyob hauv OS, NVME SSD pom hauv OS tom qab thauj khoom thiab tuaj yeem siv tau. Tsis muaj software ntxiv rau Linux. Rau kev khiav hauj lwm systems ntawm BSD tsev neeg thiab lwm yam Unixes, txoj kev yog feem ntau kuj haum.
Txhawm rau khau raj los ntawm ib qho tsav, nws yog qhov tsim nyog uas qhov pib khau raj (BPP), BIOS lossis EFI (UEFI) muaj cov tsav tsheb rau cov cuab yeej no. NVME SSD drives yog cov khoom siv tshiab zoo piv rau BIOS, thiab tsis muaj cov tsav tsheb zoo li no hauv firmware ntawm cov motherboard qub. Hauv EFI yam tsis muaj NVME SSD kev txhawb nqa, koj tuaj yeem ntxiv cov cai tsim nyog, thiab tom qab ntawd ua haujlwm tag nrho nrog cov cuab yeej no ua tau - koj tuaj yeem nruab lub operating system thiab khau raj. Rau cov laus systems nrog lub thiaj li hu. "legacy BIOS" loading OS tsis zoo li yuav ua tau. Txawm li cas los xij, qhov no tuaj yeem ua haujlwm ib puag ncig.
Yuav ua li cas ua nws
Kuv siv openSUSE Leap 15.1. Rau lwm lub tshuab Linux cov kev ua yuav yog kwv yees li qub.
1. Cia peb npaj lub computer rau kev txhim kho lub operating system.
Koj xav tau lub PC lossis server nrog dawb PCI-E 4x lossis txuas txuas ntev dua, txawm li cas los xij, PCI-E 1.0 txaus. Tau kawg, qhov tshiab ntawm PCI-E version, qhov siab dua yuav yog. Zoo, thiab qhov tseeb, NVME SSD nrog M.2 rau PCI-E 4x adapter.
Koj kuj xav tau qee yam tsav nrog lub peev xwm ntawm 300 MB lossis ntau dua, uas pom los ntawm BIOS thiab los ntawm qhov koj tuaj yeem thauj khoom OS. Qhov no tuaj yeem yog lub hard drive nrog IDE, SATA, lossis SCSI kev sib txuas. SAS. Los yog USB flash drive lossis daim npav nco. Nws yuav tsis haum rau lub floppy disk. CD-ROM yuav tsis ua haujlwm thiab yuav tsum rov sau dua. DVD-RAM - tsis muaj tswv yim. Cia peb hu qhov no yog "qhov qub BIOS drive".
2. Thauj Linux rau kev teeb tsa (los ntawm qhov chaw kho qhov muag lossis bootable flash drive, thiab lwm yam).
3. Thaum kos lub disk, peb yuav faib cov OS ntawm cov muaj drives:
3.1. Cia peb tsim ib qho kev faib rau GRUB khau raj loader thaum pib ntawm "legacy BIOS drive" nrog qhov loj ntawm 8 MB. Kuv nco ntsoov tias qhov no siv cov yam ntxwv ntawm openSUSE - GRUB ntawm ib qho kev faib cais. Rau openSUSE, default file system (FS) yog BTRFS. Yog tias koj tso GRUB rau ntawm qhov muab faib nrog BTRFS cov ntaub ntawv kaw lus, lub kaw lus yuav tsis khau raj. Yog li ntawd, ib qho kev cais yog siv. Koj tuaj yeem tso GRUB rau lwm qhov chaw, tsuav nws khau boots.
3.2. Tom qab muab faib nrog GRUB, peb yuav tsim ib qho kev faib nrog ib feem ntawm lub kaw lus kaw lus ("hauv paus"), uas yog "/boot/", 300 MB loj.
3.3. Cov khoom seem - seem ntawm lub kaw lus kaw lus, muab faib rau kev sib pauv, tus neeg siv muab faib "/home/" (yog tias koj txiav txim siab tsim ib qho) tuaj yeem muab tso rau ntawm NVME SSD.
Tom qab kev teeb tsa, lub kaw lus thauj khoom GRUB, uas thauj cov ntaub ntawv los ntawm / khau raj /, tom qab ntawd NVME SSD dhau los muaj, ces lub kaw lus khau raj los ntawm NVME SSD.
Hauv kev xyaum, kuv tau txais kev nrawm nrawm.
Cov peev txheej yuav tsum muaj rau "qhov qub BIOS tsav": 8 MB rau GRUB muab faib - qhov no yog lub neej ntawd, thiab qhov chaw ntawm 200 MB rau / khau raj / . Kuv muab 300 MB nrog ib qho cia. Thaum hloov kho cov ntsiav (thiab thaum txhim kho cov tshiab), Linux yuav rov ntxiv / khau raj / muab faib nrog cov ntaub ntawv tshiab.
Ceev thiab nqi kwv yees
Tus nqi ntawm NVME SSD 128 GB yog kwv yees li ntawm 2000 rubles.
Tus nqi ntawm M.2 - PCI-E 4x adapter yog kwv yees li 500 rubles.
Kuj tseem muaj M.2 - PCI-E 16x adapters muag rau plaub NVME SSD drives, tus nqi ntawm qhov chaw ntawm 3000 rubles. - yog leej twg xav tau.
Txwv ceev:
PCI-E 3.0 4x txog 3900 MB / s
PCI-E 2.0 4x 2000 MB/s
PCI-E 1.0 4x 1000 MB/s
Tsav nrog PCI-E 3.0 4x ua tiav qhov nrawm ntawm 3500 MB / s hauv kev xyaum.
Peb tuaj yeem xav tias qhov ua tiav tau nrawm yuav zoo li no:
PCI-E 3.0 4x txog 3500 MB / s
PCI-E 2.0 4x txog 1800 MB / s
PCI-E 1.0 4x txog 900 MB / s
Uas ceev tshaj SATA 600 MB/s. Qhov kev ua tau zoo rau SATA 600 MB / s yog li 550 MB / s.
Ntxiv mus, nyob rau hauv cov laus motherboards SATA ceev ntawm on-board maub los yuav tsis yog 600 MB / s, tab sis 300 MB / s los yog 150 MB / s. Ntawm no onboard maub los = SATA maub los ua rau sab qab teb ntawm lub chipset.
Kuv nco ntsoov tias NCQ yuav ua haujlwm rau NVME SSDs, tab sis qhov no yuav tsis yog rau cov laus dua onboard controllers.
Kuv tau ua qhov suav rau PCI-E 4x, tab sis qee qhov tsav tsheb muaj PCI-E 2x tsheb npav. Qhov no txaus rau PCI-E 3.0, tab sis rau cov laus PCI-E cov qauv - 2.0 thiab 1.0 - nws yog qhov zoo dua tsis txhob siv xws li NVME SSDs. Tsis tas li ntawd, ib tug tsav nrog ib tug tsis nyob rau hauv daim ntawv ntawm ib tug nco nti yuav ceev dua tsis muaj nws.
Rau cov neeg uas xav kom tso tseg tag nrho cov on-board SATA maub los, kuv pom zoo kom siv Asmedia ASM 106x (1061, thiab lwm yam) maub los, uas muab ob SATA 600 ports (sab hauv lossis sab nraud). Nws ua haujlwm zoo heev (tom qab hloov kho firmware) thiab txhawb nqa NCQ hauv AHCI hom. Txuas ntawm PCI-E 2.0 1x tsheb npav.
Nws sab saum toj ceev:
PCI-E 2.0 1x 500 MB/s
PCI-E 1.0 1x 250 MB/s
Qhov ceev tau ua tiav yuav yog:
PCI-E 2.0 1x 460 MB/s
PCI-E 1.0 1x 280 MB/s
Qhov no txaus rau ib SATA SSD lossis ob HDDs.
Pom qhov tsis txaus
1. nyeem tsis tau nrog NVME SSD, tsuas muaj cov ntaub ntawv dav dav ntawm cov chaw tsim khoom, tus lej xov tooj, thiab lwm yam. Tej zaum vim yog lub motherboard qub dhau lawm. Rau kuv qhov kev sim tsis zoo, kuv siv MP qub tshaj plaws uas kuv tuaj yeem pom, nrog nForce4 chipset.
2. TRIM yuav tsum ua haujlwm, tab sis qhov no yuav tsum tau kuaj xyuas.
xaus
Tseem muaj lwm txoj hauv kev: yuav SAS maub los nrog PCI-E 4x lossis 8x connector (puas muaj 16x lossis 32x?). Txawm li cas los xij, yog tias lawv pheej yig, lawv txhawb SAS 600, tab sis SATA 300, thiab cov khoom kim heev yuav kim dua thiab qeeb dua li txoj kev tau hais los saum toj no.
Rau kev siv nrog M$ Windows, koj tuaj yeem nruab software ntxiv - bootloader nrog cov tsav tsheb built-in rau NVME SSD.
Saib ntawm no:
Kuv caw tus nyeem ntawv los ntsuas nws tus kheej seb nws puas xav tau kev siv NVME SSD, lossis seb nws puas yuav zoo dua los yuav lub motherboard tshiab (+ processor + nco) nrog M.2 PCI-E txuas uas twb muaj lawm thiab kev txhawb nqa rau booting los ntawm NVME SSD to EFI.
