A feature of the Data Set management command available in the ATA8-ACS-2 specification. The command is used in the operating system used to wipe invalid data blocks on solid-state drives (SSD) which are no longer in use – including data blocks which have been left by deleted files.
Traditionally, flash media could not overwrite existing data as it first would need to first perform a 512KB block erase. Overwriting data on a SSD, required a longer read-modify-write operation which decreased the performance and speed of the SSD. The Trim command enables file system information to be collected by the OS and sends it to the SSD controller, which otherwise would not know it could delete those blocks.
The purpose of Trim is to improve the speed of SSD drives and ultimately boost the drives’ overall read and write performance. Both the operating system and SSD firmware must support Trim. Trim may also be referred to as DisableDeleteNotify, or SSD Optimizer.
- Triple DES
Also referred to as 3DES, a mode of the DES encryption algorithm that encrypts data three times. Three 64-bit keys are used, instead of one, for an overall key length of 192 bits (the first encryption is encrypted with second key, and the resulting cipher text is again encrypted with a third key).
Refers to the Intel 430 family of Pentium chipsets. The first in family, the 430FX, is called the Triton; the enhanced 430 HX is called Triton 2. The Triton chipset supports the PCI bus and was the first x86 chip to use EDO DRAM. The Triton 2 is one of the fastest Pentium chipsets, with […]
- Trojan Horse
A destructive program that masquerades as a benign application. Unlike viruses, Trojan horses do not replicate themselves but they can be just as destructive. One of the most insidious types of Trojan horse is a program that claims to rid your computer of viruses but instead introduces viruses onto your computer. The term comes from […]
A UNIX operating system from Compaq.
- TruSurround XT
TruSurround XT is the second generation of SRS TruSurround. Building upon its patented predecessor, TruSurround XT solves the problem of playing 5.1 or 6.1 multichannel content over two speakers (or headphones). TruSurround XT accepts input from up to a seven channel (6.1) audio source and processing a two-channel output. When receiving multichannel content, TruSurround XT […]
