Best value SSD out there - installation can be frustrating, learn from my mistakes!

February 24, 2018

Verified Purchase

I got the 256GB SATA drive, and it's by far the best value SSD out there that I could find. Performance-wise it might not be the fastest, but for my needs (and on my old motherboard which only gets SATA I speeds anyway) it is perfect. Excellent customer service from the company, too. I thought I had a problem with the first one I received (in hindsight it was probably working just fine) and the company sent a new one super fast, no hassle at all. With my Windows 10 now on the SSD, it feels like a new machine.

Installation tips: I am not a hardware or computer expert and do not profess to be, and I did the installation myself on a desktop and learned a lot in the process (mostly through Google and message boards). This isn't a detailed installation guide, just a few tips I learned. So here's how you can learn from my mistakes and avoid some frustration:

1. If your computer doesn't see your drive, and you can't see the drive in disk management or in BIOS, go into BIOS and make sure your SATA ports are not disabled. I had this issue and took me forever to realize this was the problem. In hindsight it should have been obvious, but I was learning my way through all this so I didn't think of it.
2. You will also likely need to go into BIOS and make sure your SATA operation is set to AHCI. BUT (and this is important) if your settings are not on AHCI and you switch to them in BIOS, you will get a blue screen on startup and crash. You will need to use the command prompt (as admin) first to ensure a startup in safe mode by typing "bcdedit /set {current} safeboot minimal", THEN restart and go into BIOS, switch over to AHCI, restart in safe mode, and go back into command prompt as admin, type "bcdedit /deletevalue {current} safeboot", restart again, and you will be all set. After doing that, I was finally able to see both drives in the boot order.
3. If you want to move your Windows OS from an existing drive to your SSD, you can try to clone it and maybe you'll have no problem, but after trying multiple clones with different programs and having them fail every time, I finally just did a fresh install of windows from a USB (or other media device) and was glad I did. Don't waste your time with cloning and just do the fresh install. It could save you countless hours of frustration.

I don't know if that will help anyone or not, but I hope it will. And if that all sounds WAY too complicated to you, find a friend who is well versed in computer hardware, buy them a case of their favorite beer, and plead with them to do the installation for you.

Great drive, very fast, however read on if this is smaller than your current drive.......

January 29, 2018

Verified Purchase

Very fast, my laptop would literally take 5 minutes to boot up to a usable state, with this 30 secs. However if you are DOWNSIZING from a larger HDD to this, it is not straightforward, I have upgraded dozens of drives over the years, I don't claim to be an expert, but probably above average in computer skills. I had an awesomely slow 1TB drive on my laptop, way more storage than I needed. I took off extra stuff and got it to about 150gb, then tried several clone/drive migration programs and none would work for some reason or another. I read online it is possible, but seemed complicated, and frankly I didn't want to pop extra money for a "pro" clone program, with no guarantees they would work, or get into system settings.
Solution-- I ended up just doing a clean reinstall of windows 10 and programs, and kept my old drive as a backup, seemed like a much faster solution, plus gave me chance to get a bunch of bloatware off my computer.

Amazing price for a top notch Solid State Drive !!

April 12, 2018

Verified Purchase

Thought Id give silicon power a try with my laptop .. I Recently purchased a Sandisk ssd for my girlfriends laptop . I was so amazed at the boot-up and loading time that I had to get one for myself ..I Did a little Amazon reviewing and decided on this model ..The price is about the best ..I registered it for the warranty ...Hoping it lasts but it looks like it should..Just remember to set your bios settings to AHCI for ssd and either a fresh install of windows or clone the drive ...This model doesnt come with cloning software or a Sata cable , but if you do a new install , you dont need either of those ..All in all , a great purchase and I would buy it again !

THIS is ONE thing you must get for your computers. Lightening Fast Results.

March 27, 2018

Verified Purchase

A Superb Fantastic SSD.The Price, The size all of it a great deal. I replaced the 500gb cloned it with EASEUS and I am glad I got rid of the slow Hard Drive. Makes the computer lightening fast if you got a good cpu and memory. And even if you have not a good cpu, memory combination. It will still make a very big difference in speed. This is a great product if you want to overcome any lagging by your laptop or desktop. I got a sony vaio VPCF115FM laptop 6gb memory and i7 cpu. It has become so fast I am amazed. As if I have upgraded the memory and CPU and not the hard drive. Totally Crazy Speeds on my Laptop.

As good as the best

This is my third solid state drive. It performs like most others. I have has OCZ, SanDisk, and now the Silicone Power. It boots very fast and now my Ryzen has no lag.

Windows 10 boots in about 15/s. If I count the time from when the BIOS is done loading, I'd say 7/s. I am pleased. This is my first product from Silicone power and I will be buying again.

Inexpensive SSD for your computing needs!

March 2, 2018

Verified Purchase

Inexpensive, and is working perfectly fine.

System I installed it in is having issues with the onboard Intel AHC9 raid SATA ports, so I ended up getting a PCIE adapter card (this one: https://smile.amazon.com/dp/B01452SP1O ) and mounting this drive directly to the adapter card, and the other SSD in the system to the external port on that card. Everything is working fine, and I'm completely happy with the drive!

Works flawlessly. Very fast booting to OS.

April 25, 2018

Verified Purchase

After receiving the SSD I placed it in my SABRENT USB hard disk docking station. I put my failing drive into the HDD1 slot and this new SSD into the HDD2 slot. I used the auto cloning feature of the SABRENT Dock to clone the failing drive to the old drive. It took about four hours but every thing worked. I placed the SSD into my laptop and powered up. After updating the CMOS to the new drive and rebooting I noticed Windows 7 booted in 20 seconds. Everything about the laptop is faster. I am a very satisfied customer. I am ordering the same SSD today for my Windows 7 tower.
