The 80Gb Intel MLC SSDs have been hard to find in-stock and prices keep varying .... The original list price on the x25m 80Gb MLC drive was $230 - and it was *supposed* to be available for less than that. Demand has been high and a lot of on-line sellers have taken advantage of the demand to keep prices high. In pa...

Hi Yamaban, Great expalanation. I think you know how to buy an ssd. There is no doubt about samsung ssds quality vs other. My question about neutron was to get your opinion about this product. My doubt was about differences between slc, mlc and tlc. Mlc endurance respect tlc is better and I though that the mlc of neutron gives me more endurance respect to the tlc. From a technic point of view, why the samsung tlc is better of corsair mlc? And what about v nand? Have you used it? Thanks in advances Il 28/ott/2016 20:33, "Yamaban...

Hi all ! Last month, i gave a presentation of Xen. I recorded the demonstrations which I presented and i put them on my blog ... Here is videos of Xen in action : (works great with mplayer) 1. Several OS simultaneously (multipleOS.avi<http://mlc.homelinux.com:88/xenpr/Videos/multipleOS.avi>- 17M) 2.

Hi, I don''t know if it''s already been discussed here, but while thinking about using the OCZ Vertex 2 Pro SSD (which according to spec page has supercaps built in) as a shared slog and L2ARC device it stroke me that this might not be a such a good idea. Because this SSD is MLC based, write cycles are an issue here, though I can''t find any number in their spec. Why do I think it might be a bad idea: L2ARC is quite static in comparison with ZIL and L2ARC takes all the place it can get. But if 90% of the device are nearly statically allocated, the devices possibili...

Are any of you using the Intel 320 as ZIL? It''s MLC based, but I understand its wear and performance characteristics can be bumped up significantly by increasing the overprovisioning to 20% (dropping usable capacity to 80%). Anyone have experience with this? Ray

The standard controller that has been recommended in the past is the AOC-SAT2-MV8 - an 8 port with a marvel chipset. There have been several mentions of LSI based controllers on the mailing lists and I''m wondering about them. One obvious difference is that the Marvel contoller is PCI-X and the LSI controllers are PCI-E. Supermicro have several LSI controllers. AOC-USASLP-L8i with the

...oesn't it reassure me > so? And how can I handle a linux-formatted USB flash drive in the > absence of my system giving me any guidance? The problem is that it really depends on the quality of the flash drive. Two main things drive this: 1) Whether the flash used in the drive is SLC. MLC, or TLC. This will tell you how many write cycles the flash can support. This is where you will see numbers such as 10,000 write cycles, all the way down to 1,000 write depending on the quality of the flash used. 2) The quality of the Flash Translation Layer (FTL). The important thing to rememb...

I have some questions about the choice of SSDs to use for ZIL and L2ARC. I''m trying to build an OpenSolaris iSCSI SAN out of a whitebox system, which is intended to be used as a backup SAN during storage migration, so it''s built on a tight budget. The system currently has 4GB RAM, 3GHz Core2-Quad and 8x 500GB WD REII SATA HDDs attached to an Areca 8port ARC-1220 controller
