Review: Samsung 830Samsung stands out from the rest in this review as, now that Intel has stopped making controllers, it’s the only manufacturer that can claim to master the full SSD production process, from the controller to the flash memory and DRAM memory cache and of course the firmware.
The Samsung 830 therefore uses an in-house controller, the S4LJ204X01, in-house DDR2 memory and in-house 27nm Toggle flash memory. The Samsung 830 is 7mm thick, is available in 64, 128, 256 and 512 GB stand alone versions as well as desktop (3.5" adaptor, SATA cable, Molex to SATA adaptor, Norton Ghost 15) and Notebook (layer to take it to a thickness of 9.5mm, an SATA to USB cable, Norton Ghost 15) kits in a similar offering to Kingston’s.
They're guaranteed for three years and come with a fairly thorough utility that allows you to launch TRIM on the free space in Windows XP and Vista, also possible with the Intel Toolbox.
The official performance levels given are high, except for random reads where other SSDs are a good deal faster. Note that write performance increases as you go up the range from the 64 GB to the 128 GB and 256 GB models, with the graph stabilising with the 512 GB. Even the 64 GB version offers very decent performance.
Inside the Samsung 830 then, there's a Samsung S4LI204X01 controller with 256 MB of Samsung DDR2 and only four 32 GB Samsung flash chips. Of course you can’t get this amount of memory on a single die and each chip has actually four dies. This memory is engraved at 27nm and uses Toggle type bus mode.
