Jak vybrat vhodné PC? Prosím o radu

Možná by stačilo udělat údržbu PC, pokud požadujete stejnou práci po počítači několik let a pomalu přestávalo stíhat.

Naše postarší domácí PC již nestačí na naší práci.

Defragmentovat, včetně systlémových souborů

Napsal domain;887013

jakou praci?

odkdy nestaci?

zacali jste editovat videa nebo rendrovat 3d vizualizace?

pokud delate to same, staci reinstalovat

(pripadne u notebooku vycistit ventilator)

photoshop se seká již od začátku

Napsal domain;887025

po reinstalaci nemusis nic defragmentovat

obecne ma defragmentace pochybny prinos

lepsi je mit dost mista na HDD

a tedy ten pocitac mozna potrebuje vetsi nebo dalsi drive

- máme eshop, tedy administrativa s tím spojemá

- photoshop se seká již od začátku

- videa ani nesleduji, to nešlo pořádně nikdy, to bych musel čekat týden

v tom pripade je spravne: "Pocitac od zacatku nestaci na nasi praci."

Navíc slušný defragmentační program umí...

Ne tak docela.

Práci ve photoshopu dělám na notebooku. Na pevném PC si jen některé věci otevírám.

Není nutné aby PC photoshop stíhal ale pokud budu pořizovat jiný, již to budu požadovat.

zijes v predstavach z 90. let

napr. u SSD nikdo normalni defragmentaci delat nebude

http://en.wikipedia.org/wiki/Solid-state_drive#SSD-optimized_file_systems

Versions of Microsoft Windows prior to Vista do not take any special measures to support solid state drives. Partitions can be manually aligned before OS installation. Defragmentation negatively affects the life of the SSD and has no benefit. The TRIM command can be triggered using third-party tools to help maintain performance over time.

Starting from Windows 7, the standard NTFS file system provides TRIM support (other file systems do not support TRIM).

The registry key HKEY_LOCAL_MACHINESystemCurrentControlSetControlFileSystemDisableDeleteNotification can be set to 1 to prevent TRIM command being issued. This can be useful in situations where data recovery is preferred over wear leveling (TRIM irreversibly resets all data that it manipulates).

Windows 7 and 8

Windows 7 has support for SSDs. Support in Windows 8 is similar. The operating system detects the presence of an SSD and optimizes operation accordingly. For SSD devices Windows disables defragmentation, Superfetch and ReadyBoost, which are boot-time and application prefetching operations. It also includes support for the TRIM command to reduce garbage collection for data which the operating system has already determined is no longer valid. Without support for TRIM, the SSD would be unaware of this data being invalid and would unnecessarily continue to rewrite it during garbage collection causing further wear on the SSD.

Windows Vista

Windows Vista generally expects hard disk drives rather than SSDs. Windows Vista includes ReadyBoost to exploit characteristics of USB-connected flash devices, but for SSDs it only improves the default partition alignment to prevent read-modify-write operations which reduce the speed of the SSD. This is because most SSDs are typically aligned on 4 KB sectors and most systems are based on 512 byte sectors with the default partition set up unaligned. The proper alignment really does not help the SSD's endurance over the life of the drive, however some Vista operations, if not disabled, can shorten the life of the SSD. Disk defragmentation should be disabled because the location of the file components on an SSD doesn't significantly impact its performance, but moving the files to make them contiguous using the Windows Defrag routine will cause unnecessary write wear on the limited number of P/E cycles on the SSD. The Superfetch feature will not materially improve the performance of the system and causes additional overhead in the system and SSD, although it does not cause wear. There is no official information to confirm whether Windows Vista sends TRIM commands to a solid state drive.

Samsung releases SSD-specific F2FS file system

Samsung releases SSD-specific F2FS file system

Samsung's F2FS file system promises to boost the performance and longevity of solid-state storage devices, but will it ever reach Windows?

Samsung has designed and launched a new file system with a singular aim in mind: improving the longevity and performance of NAND flash-based storage devices.

Dubbed the Flash-Friendly File System, or F2FS, and developed by Samsung's Jaegeuk Kim, the new file system attempts to address some of the issues with using formats designed for spinning-disk devices on solid-state drives including those that lead to performance-sapping cleaning cycles and loss of throughput over time.
