SSD Disky

[faugusztin]

Okolo 200 ? Reactor s prvym spolahlivym, nesekajucim JMicron radicom ? Nemylis si to s Nova (Indilinx) alebo Force (SandForce) ?

[dexterav]

hmm nj
no nenapadlo ma že tá 612 má také malé skore

[Brandoo]

Corsair F60 bude rychlejsi ako ten R60 co je upnuty aj banchmark na predoslej strane ?

A este daco. Na guru3d, kde je recka RevoDrive su aj rady ako maximalizovat vykon SSD vo win vista / 7

SSD / Flash Storage life-span recommendations

Drive wearing on any Flash based drive will always be a ghost in the back of your mind. Here are some recommendations and tips for a long lifespan and optimal performance. Basically, what is needed is to eliminate the HDD optimizations within Vista (that cause lots of small file writes like superfetch and prefetch), things like background HDD defragmentation (that causes lots of small file write drive activity). In short (and this is for Vista and Windows 7):

* Drive indexing disabled. (useless for SSD anyway, because access times are so low).
* Prefetch disabled.
* Superfetch disabled
* Defrag disabled.

So make sure you disable prefetchers. Also, especially with Vista and windows 7, make sure you disable defragmentation on the SSD disk. You do not have a mechanical drive anymore so it is not needed, let alone you do not want defragmentation to wear out your drive, and Vista does this automatically when your PC is in idle (picking it's nose).

Don't get me wrong though, you could do a defrag without any problems, you just do not want that to be regular.

For Superfetch/prefetchers and other services, at command prompt just type: services

Use Windows 7 / Vista's services to disable them. To disable defragmentation:

Windows 7 and Vista Automatic Defrag:

1. Click Start
2. Click Control Panel
3. Select the Control Panel Home
4. Click System and Maintenance
5. Under the Administrative Tools section at the bottom, click Defragment your hard drive
6. You may need to grant permission to open the disk defragmenter
7. Click or unclick Run automatically (recommended) depending on if you want this feature enabled or disabled.
8. Click OK

OR alternatively at the Vista start prompt just type : dfrgui

Now over time your SSD will get a little fragmented. Simply do manual defragment folks; the difference between daily automated defragmentation or doing it yourself once a year .. is a big big difference.

Apply common logic and sense, always. And good news, Windows 7 will have many improvements and tips like shown above already automatically setup for you.

Windows 7 and the SSD TRIM feature

Windows 7 and Windows Server 2008 R2 support the TRIM function, which the OSs use when they detect that a file is being deleted from an SSD.

When the OS deletes a file on an SSD, it updates the file system but also tells the SSD via the TRIM command which pages should be deleted. At the time of the delete, the SSD can read the block into memory, erase the block, and write back only pages with data in them. The delete is slower, but you get no performance degradation for writes because the pages are already empty, and write performance is generally what you care about.

Note that the firmware in the SSD has to support TRIM, but the good news is that firmware updates are coming out for many SSDs to add TRIM support.

TRIM only improves performance when you delete files. If you are overwriting an existing file, TRIM doesn't help and you'll get the same write performance degradation as without TRIM.

Enable AHCI

The last tip we want to give you to gain a little extra performance boost is that you enable AHCI mode. AHCI mode can help out greatly in performance for SSDs. Now, if you swap out an HDD for an SSD with the operating system cloned and THEN enable AHCI in the BIOS, then you'll get a boot error / BSOD.

The common question is, is there a solve for this ?

To answer that question (and as we do safely with all modern chipsets) there is a way to safely enable AHCI mode. Here we go:

1. Startup "Regedit
2. Open HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlset / Services
3. Open msahci
4. In the right field left click on "start" and go to Modify
5. In the value Data field enter "0" and click "ok"
6. exit "Regedit"
7. Reboot Rig and enter BIOS (typically hold "Delete" key while Booting)

In your BIOS select "Integrated Peripherals" and OnChip PATA/SATA Devices. Now change SATA Mode from IDE to AHCI.

You now boot into windows 7 or Vista, and the OS will recognize AHCI and install the devices. Now the system needs one more reboot and voilla .. enjoy the improved SSD performance.

Da sa to teda aplikovat aj na klasicke SSD dufam ... Pred instalaciou treba nastavit radic pre SATAII na AHCI ze ? Koli nizsej odozve

Ak by ste chceli daco doplnit ku tym radam tak nech sa paci, budem len rad. Pretoze tohto mesiaca pochovavam HDD na system a nahradim ho SSDckom.

emPORiO:
ANO, F60 bude urcite omnoho rychlejsia ako R60. Hlavne zapis.
vsetky tie rady su pekne, ale Win7 ti to vsetko nastavi samo pri instalacii ( teda aspon u mna to tak bolo ). Vista moc vhodna na SSD nieje, lebo nepodporuje TRIM a musis to vseto nastavovat rucne.
A ano, radic ma byt ako AHCI.

[Brandoo]

Ok diky .a dufam ze nastavy dobre ... ak nie, tak nech si ma nepraje. Potom este vypnem tie MS blbosti pre optimalizovanie HDD lebo to spomaluje SSD ako to pisu aj na guru3d

Samozrejme budem mat Windows 7, ine ani nechcem (zatial)

[dexterav]

F60 je SandForce tým je asi povedané všetko
pri SSD nejde často ani o samotné spomaľovanie ako o opotrebovanie

[Brandoo]

A čo sa tam akože opotrebúva ? nemá to žiadne mechanické časti ani sa to nezahrieva ... iba trochu. Nemá to náhodou životnosť ako aj pamäťový modul (RAM)? alebo v čom sa opotrebúva, nerozumiem tomu

Ano, je to zivotnost cipu.
Zjednodusene, cipy maju obmedzeny pocet zapisov do jednej bunky (cipu), pri MLC cipoch to moze kludne byt iba 1000 az 10000 krat na bunku.

[Brandoo]

No dobre, ale ake nasledky ma toto opotrebovanie ? znizi sa rychlost alebo zmensi sa velkost ? ked uplynie zivotnost bunky

Da sa povedat, ze to je podobne ako aj u ludi .. ze bunka odumrie za 7 - 10 rokov ? ... samozrejme nahradi ju nova bunka


Len ma strasite nic nieje nekonecne to hej ... ale tak 10 rokov by to malo vydrzat v dobrej kondicii si myslim

[faugusztin]

Ano, ale pocet rezervnych buniek nie je neobmedzeny. Proste treba ratat s tym, ze za tych 5-20 rokov uz bude disk nepouzitelny kvoli tomu, ze jeho kapacita pojde dole.

to je práve otázne kedže SSD sú relatívne novo rozšírená vec...
ono je práve otázka že čo by sa stalo keby SSD zapisovalo stále veľmi často na jedno miesto, to je napr, pagefile s pevnou veľkosťou
proste zo SSD to je stále trochu zložité
čo sa týka rezervy tá je niekedy dosť značná, pár typov SSD si po update FW pripočítalo k dobru nejaké GB práve kôli zmenšeniu množstva rezervnych buniek

[Apeiron]

Zdravim pani,

v pondelok kupujem OCZ Vertex2 Series 60GB.
Nikde som nenasiel aky radic pouziva...

Apropo ake programy pouzivate na benchmark?

[dexterav]

radič je SF
ked kupuješ SSD to je prvá vec krorú by si mal vedieť

dobré sú PCmark2005 a Vantage
potom AS SSD Benchmark
ATTO disk bench mark je trochu optimistický čo sa HDD týka (zápis 4kB, resp malých súborov)

Maju to priamo na stranke vyrobcu....
