good drive, used it in old Dell laptop with Windows 8, definitely speedier and more reliable than traditional hard drive.

Works great so far as a replacement for my wife's old Thinkpad.  The drive said "not for use in a laptop" but has been working great.

Replaced a defective laptop home server drive with this one, been working great for about 4 months now. Though installation was a bit rough since this drive is a bit thick (tall) and didn't quite fit my laptop. I imagine that it is thicker than the previous Toshiba 512GB because of the larger capacity.

The drive fits great in my dell laptop, the ssd I mounted inside works well in combination with it. very very easy install and it looks and feels like a quality product. hell my old drive fits in the packaging so I keep it in there in case I need it. great deal for price compared to other similar items.

Works perfectly for an old laptop (Dell 1526) used for school work.  No issues at all so far and everything seems to run much faster than the standard hdd that was previously in the laptop.  Helps my laptop from overheating too. My regular hdd, would generate heat and when combined that with the head of the cpu/gpu, it would get pretty toasty and performance drops would occur because of it.
Recommended.

Before you buy this, be SURE you know the difference between a traditional SSD and an mSATA SSD. These are MUCH smaller and are made for specific laptops.

I installed this drive in the extra mSATA slot in my Ideapad Yoga (a grand machine). Screws DID come with mine, but from other reviews it looks like its kind of gamble whether you'll get them or not. Otherwise, just steal one of those other screws from inside your laptop, it doesn't need all of them.

After that, I just formatted the drive, and presto, it all worked; simplicity itself.

Exactly what I needed for my older Dell laptop.

So far, so good. I installed this hard drive into my Dell N4110 four months ago and it seems to be working great. Definitely better than the one that was failing.

I bought this drive to replace a dead drive on a Dell Inspiron 531.  Installation was easy because I replaced the exact same drive and saved the computer because it would not even boot from the old drive.  This was easier and cheaper than taking it in for service and now I have a clean new dirve that should last several years.
My computer now runs like new.

This drive does everything I hoped it would but I never recommend hard drives before they have worked reliably for  at least one year with no troubles. This drive has only been in my Dell laptop for a month and therefore I am unable to say anything except that it is still functioning as expected. I like the long warantee which is the primary reason I went with it.

Bit of a debacle with the drive, and I'm giving Crucial the benefit of the doubt here with 3 stars. Customer wanted to upgrade an older HP laptop, purchased this drive and no matter what I did (updated drive firmware and updated to latest BIOS) the drive would not be recognized as a boot device. Once in Windows (old boot device connected via eSATA) the Crucial SSD was recognized by the OS.

Ultimately I had to swap the Crucial SSD with a similar Kingston device (which worked flawlessly) from another machine and also swap the data between them. Also had to explain to the customer why this was taking longer than originally estimated. While I'm certain that the issue was caused by HP's BIOS, there really is no excuse for connecting a SATA drive of any kind - it is a universal standard - and having an issue like that. (Notably and especially when a competitor's product works.) I'll grant that there is something of a crapshoot pairing new and old hardware, and the blame may not lie on Crucial in particular, but in the end I'd recommend anyone looking to upgrade an older system give this one a pass.

The speed and price/performance of the drive are good to excellent, and it performs well on a more recent Dell laptop. Were it not for the issue I had it would have been 5 stars without question. Were compatibility to be enhanced by a firmware update I would be more than willing to amend this review.

Used this drive in my HP dv2700 laptop. My laptop originally came with a Hitachi 160GB 5400rpm drive which I quickly filled up. So I wanted to increase my laptop HD capacity. I also figured why not upgrade to 7200rpm as well. 320GB is plenty large for my needs and I definitely noticed the difference in read/write speeds compared to the 5400rpm Hitachi drive that came with my laptop. And to me this drive seems quieter than the Hitachi drive.

So nothing but positive things to say about this drive. Well worth the purchase.

At this point, I've probably installed a couple of hundred 120GB SSD's into laptops with failed hard drives, so it's kind of hard for me to feel like one drive is clearly superior to another. At this point, a drive really needs to fail at doing something to make much of an impression, and obviously, that's not a good one. The Toshiba OCZ Trio 150 120GB drive failed to make such an impression, and it's continued to fail to make it since I used it to replace the spinning drive in my old X220 tablet. That's generally a good thing. Replacing traditional hard drives in most laptops is generally a huge performance boost (most laptops use drives that run at 5400 RPM rather than the faster 7200 RPM drives that desktops more typically use), and that's been the case here. You do lose some storage capacity for the price (the drive I replaced was 320GB), but for mobile devices, the performance boost is generally worth the trade-off.

Installation was a breeze and only took a few minutes (this varies greatly from laptop to laptop, but the X220 tablet is one of the easiest ones to change a drive on). The X220 had no issues recognizing the drive and reinstalling Windows via a USB 2.0 flash drive took around 12 minutes, which is a lot faster than it would have been with the original hard drive. Performance is quick and most people will be thrilled.

This is a great SSD for the money. There are cheaper ones out there, some of which are just as good, but this is a solid drive.

I bought 2 to replace the disks in my old Dell Precision 9200 and Windows 7 kept rejecting the drives.  Sorry, I forget what the exact error was.

But I put them in my Dell 3500 and they're working well.  Pretty peppy performance and a great price.

Even though platter-drives are going the way of the dinosaur, I needed to replace the disk on a co-worker's Toughbook.  The black series is the performance line of WD and still provides reliability.  I'm spoiled with SSD's now, but for certain purposes, this is a good reliable drive for older hardware.

I used this drive in an old asus 900hd netbook I have. It fit perfectly and made the system boot and run programs much faster. The battery lasts longer now as well.

The drive worked in my 5 yr old laptop but when it came to my less than one yr old MacBook Pro and Dell Laptop it wasn't recognized.  I wouldn't buy it...
