Re: [H] Question of solid state drives
Hello all, When it comes to SSD drives they are great for bootdevices and program drives.Remember,all user data should be on another hard drive. I prefer SLC drives, because they seem to run faster thanMLC. But this could be due to Operating Systems as well. Only have tested SSDon Windows XP, Windows Vista and Windows 7. Windows 7 has an enormousperformance increase of all operating systems over the others. Tests were done with a SLC and MLC drive. The testvolumes were defragged and in all windows registries the user drive was forcedto D:\users. After Defragged the drives were then cloned over to the SSD drive. I'm impressed with the performance.I wish I could get one installed in my gamingcomputer at home. But, I would not install World of Warcraft on it, due to WoWdoes write to the install directory numerous times during play.

Re: [H] Question of solid state drives
MLC drives are usually cheaper and easier to make, but with generally less performance than SLC and quite a bit less expensive. Anandtech has a couple good articles listing price/performance of the various SSD's. I'm using OCX Vertex (newer firmware) on 2 boxes and they are pretty fast and inexpensive. I also have 2 MLC drives (trancend a generic) that are very slooow and have frequent pauses that commonly plagued the 1st gen SSDs. lopaka --- On Thu, 7/23/09, Thane Sherrington th...@computerconnectionltd.com wrote: From: Thane Sherrington th...@computerconnectionltd.com Subject: [H] Question of solid state drives To: hardware@hardwaregroup.com Date: Thursday, July 23, 2009, 3:20 AM I was reading a review of the new Intel MLC drive, and he says The real strength of the Intel drives is in its random, small file, read/write performance.

Re: [H] Question of solid state drives
The pauses are due to poor jmicron controller logic, nothing inherent to the type of flash -JB On Jul 23, 2009 5:34 PM, Robert Martin Jr. lopa...@pacbell.net wrote: MLC drives are usually cheaper and easier to make, but with generally less performance than SLC and quite a bit less expensive.

Re: [H] Question of solid state drives
Agreed, but the problem is there are no available fixes or flash updates to fix many of the older drives which are still being sold regularly. Best to know before buying. lopaka --- On Thu, 7/23/09, James Boswell torazch...@gmail.com wrote: From: James Boswell torazch...@gmail.com Subject: Re: [H] Question of solid state drives To: hardware@hardwaregroup.com Date: Thursday, July 23, 2009, 9:51 AM The pauses are due to poor jmicron controller logic, nothing inherent to the type of flash -JB On Jul 23, 2009 5:34 PM, Robert Martin Jr. lopa...@pacbell.net wrote: MLC drives are usually cheaper and easier to make, but with generally less performance than SLC and quite a bit less expensive.

Re: [H] Question of solid state drives
The Vertex drives are nice. We ordered 40 of the 120GB variants at work to replace 7.2k mechanical drives in the laptops of our top customer-facing employees. There aren't many times when you can do a hardware upgrade and make people go Oh wow, holy sh** -- but the Vertex drives did just that. With the 2nd gen Intel drives on 34nm NAND, and other manufacturers soon to release 32nm NAND, I'm getting close to upgrading my Velociraptor.
