All the 2.5" SSDs are the same except for about 2 mm, which can make some difference, and performance. Those are completely different than Msata or M.2. Stay with the regular 2.5" SSDs. They are the same size and connect the same way as any notebook hard drive.
There's presently 2 types of connections between the motherboard and the drive/s. One is the older PATA/Parallel ATA which uses a 40/80-pin cable and can have 2 drives on each cable. The other is the current SATA/Serial ATA drives which have only 1 drive per cable. Both types can also be referred to as IDE, Intelligent Drive Electronics or Integrated Drive Electronics which is the printed circuit board/interface on the drive case of HDDs. SSDs I've seen have the interface in the drive's case. For ODD/Optical Disc Drive it will also be in the case. The terms do get mixed around a lot. The SSD/Solid State Drives use the SATA connection. There is a 3rd type drive that looks a lot like a RAM module, haven't worked with one of those yet but I believe the actual socket for them is quite similar to the SATA type.
I had previously upgraded my elderly Lenovo T61. It started with a noisy fan. But since I purchased a high performance P50, I figured I would try my luck and replace the RAM and add an SSD.
The feedback I received for this effort is what lead me to believe that there were different performance flavors of SATA SSD's.
Here's a quote from the time:"The current (T61) BIOS is limited to SATA I speeds only, so if you plan to use an SSD then the Middleton BIOS is a must IMHO. That would fully use the SSD capabilities... ...The standard T61 BIOS limits the data interface to SATA 1.5 speeds. Since the ICH8 chipset is actually SATA II capable, middleton has re-written the latest bios, v2.29 to include SATA II support."
For this current Dell potential project, I 'know' I read somewhere about SATA III SSD's. This is where my thinking comes from of 'different speed/performances' for SATA SSD's. I just want to be sure that the SSD I install is not only compatible but as quick as the machine can handle.
What disturbs me about Dell's description of their compatible SSD is that is doesn't give an appended # such as SATA I, II or III?
Whoever said that a little knowledge is dangerous was spot on ;-)!
Have you tried running your system through Crucials upgrade advisor? Welcome to Crucial UK GBP Store Organization
That part is up to you all brands have different speeds but you don't have to choose the best of the best
If you shop around you can find a fast and affordable one and also one with enough space requirements as well
If you do plan on going SSD make sure you clone that other drive erase it and get a enclosure and hook it up as a backup you will be flying high then
#1 SSD increase in boot speeds and even faster read and write speeds so that will take care of operations that won't be at a snails pace
#2 Increasing ram will also help that plus give it more of a snappier boost when bring up programs that combination alone will feel like you paid for a $2000 laptop

Here are some hard drive enclosures i mentioned again have a gohard drive enclosures - Newegg.com
The laptop is with my wife who is visiting her granddaughters out of state, so no. But I had given Crucial the Dell model. The memory returned was the same speed. The lowest price drive (1 of 4) was:Crucial MX300 275GB SATA 2.5" 7mm (with 9.5mm adapter) Internal SSD
CT8479547
Crucial MX300 275GB SATA 6Gbps 2.5" Internal SSD • 530MB/s Read, 510MB/s Write
upgrade for Dell Inspiron 15 (7537) system.
The identical spec 525GB drive is $60 more. The Dell is only used for infrequent travel. At those times, data is copied over existing from my wife's desktop. I'd have to check when she returns but I think the larger drive would be a waste of money.
The Crucial spec illustrates my concern voiced in the prior post. There is NO Roman numeral appended to 'SATA'. So the buyer simply 'assumes' (which I am always adverse to) that whether I'm buying on Amazon or another reputable site, I'm getting the latest flavor of SSD SATA (I had trouble even typing that last phrase)?
I guess for folks who know this stuff the Read/Write speeds are the flavor indicator?
SATA2 is a maximum of 300MB/s, SATA3 is 600MB/s therefore it follows that anything over 300MB/s has got to be SATA3, most are around the 500 mark.
All SSDs are sata III, which is the fastest. But they are also backward compatible with sata II and sata I. They are just speed limits, to you. Even if you run at sata II, it will still be much faster than any mechanical hard drive. There are no Mechanical hard drives that can even max out a sata II bus, much less sata III. So, buying a sata III Mechanical hard drive is just a marketing trick.
