Opening programs happens lickety split.
On that note, i had a friend with the same drive as mine. I built his computer. He's had 2 of them fail. He's now onto a Corsair if i recall.

Samsung 830 or Intel 520 are very good choices. Go for at least a 120 GB.

Actually, most of the current crop of SSDs should be fine. I was an early adopter and had huge headaches with my Vertex 3 when it was released.

For best practices, make sure to over-provision the SSD when it's the boot drive. Just don't allocate all the space for example when installing Windows, leave about 10% unallocated. This provides some very important extra space for the SSD firmware to do it's optimizations. Also, disable Windows drive spin down power savings. The SSD should always be powered, when the drive is idle is when TRIM, garbage collection and other maintenance activities occur. They can't happen if the drive is off. Along these lines, about once a week, reboot the computer and just leave it there over night. Don't log in or anything.

Chess, I've done some shopping there in the past. This time I got a better deal locally.

Boltron. I've not really played much with OS optimization and disk allocation. I'll have to look into it.

This advice is definitely not harmful, but it's also overly cautious. From what I understand, TRIM operations take place after only 15 seconds of idle time. Normal computer use — reading a web site, composing an email, writing a letter, etc. — does not always involve constant disk access, so there will be many opportunities for the SSD to process the TRIM commands without scheduling special down time for these to occur.

Sorry I should have elaborated a bit more. It's more than just TRIM.

Yes, I am a cautious guy and leaving the machine over-night might be overkill but overprovisioning is, I believe, good practice.

Overprovisioning reserves a portion of the drive to be used in garbage collection, wear leveling and other activities where information must be temporarily stored while a block is cleared. At the end of the day, OP helps increase the life of the drive. The extra space helps with wear leveling activities and provides additional space for remapping dead cells which is inevitable with SSDs. In addition, some argue that it may also help maintain long term performance.

The Samsung SSD Magician utility for my 830 actually has an over provisioning option built right in. This is the first para of the description: "Over-Provisioning is a feature that helps resize partitions on you SSD to create unused space on the drive, giving the controller room to manage, improve, and sustain the performance of you SSD. This feature is restricted by the amount of free space on your drive. Files are not reallocated during the resizing process."

SSD Review has an excellent article on the topic of SSD write performance degradation over time and OP:

Additionally, leaving 10% unallocated is unnecessary--manufacturers actually make something around that amount unaccessible by the OS for just that purpose. It's why you see odd sizes for SSDs (240 instead of 256, 120 instead of 128, etc).

fred, I just went through enormous research on this and the Samsung 830 (current) as Ken suggested, stands out for speed, reliability and the controller it uses. I got a 256GB and the PC is being built as we speak. Do yourself a favor and bite the bullet to get a Samsung 830 128GB.

Set it up to be the boot disc, but only have the OS and programs on it. Put the data and even the cache on a different disc.

I already cheaped out and picked up one of the discounted OCZ drives. When I was in the store the guys there pointed out I'm using a SATA 2 connection and would not even fully benefit from the speed of the drive I bought.

For the price, it will be a good experiment. The MOBO/CPU on this machine is 4 years old already, so I expect I'll replace the whole system within 2 years anyway. When I do that I'll move the SSD to my next oldest system and buy a better drive for my new one.

Old thread but I just ordered the
SAMSUNG 840 Series 250GB SATA III for 149.00 at Newegg.ca

The existing HD boot drive in my home office PC is making those telltale noises that indicate a failure is very imminent. I've already had some BSoD and the "Windows has shut down for your protection".. type errors.

It will be boot drive only (pretty much) but I opted for a bit more room so I can dual-boot Linux.

Kingston HyperX 3K SH103S3/120G 2.5" 120GB SATA III MLC Internal Solid State Drive (SSD) - $89USD today at Newegg (not .ca) That is what I am using in my server build. We'll see how it goes.

I know a lot of people have used the 840 series and liked it. (some don't, but you get that with anything)
