Three ways to install a hard drive in a laptop.
Solid state drives (SSDs) are becoming increasingly popular, especially for storing operating systems and software, but they have two big drawbacks. First, the price, and secondly, the capacity. The second drawback is even more weighty than the first one. Many buyers are willing to pay a significant amount of money for a faster system, but not many want to spend money for just 16 or 32 GB of additional disk space, even for a laptop.

In this article, we'll show you how to install a SSD drive in a laptop, but at the same time save the hard drive for storing ordinary data.
There are several ways to install a hard drive in a laptop, some are easier, and some are more complicated. Let's look at the various options.
Laptops with several HDD slots: the easiest way.
The easiest way is to buy a laptop, in which there is room for installing two (three) hard drives. In this category, most models with displays with a diagonal of 17 "and more fall in. With such a laptop it's not problematic to install both a SSD drive and a hard disk.You only need to install each of them in a separate slot.Please be careful, as some laptops (for example, 17 "MacBook Pro) have only one slot.

Notebooks with compartments for drives: a good option.
The second method is quite common for some manufacturers and consists in using the optical drive bay to place the second hard drive. The idea is quite simple: the optical drive can be removed and replaced with a second battery, an empty module for weight reduction or a hard disk. Lenovo, Dell and Toshiba, for example, supply their laptops with similar components. It's easy to make a replacement: you need to remove the snap-in with an optical drive and put the snap-in with the hard drive on the vacated space.

There can be two problems. Optical drives are often supplied in PATA format, hence, the hard drive must be in PATA format, and such snap-ins are not always easy to find. Prices, as a rule, are moderate - from $ 50 to $ 100 for a model that can accommodate a hard drive. In addition, some subnotebooks, for example, Lenovo X300, have an optical bay, but it is too thin for the hard disk to fit there.

Our decision: DIY.
Our solution is not so elegant, but effective: we replaced the optical drive with a hard drive. Next, we will discuss how to solve the problems arising from such an approach.
We took a 15 "MacBook Pro laptop. The problem is that Apple does not support the replacement of an optical drive with a hard drive, and this notebook model has only one 2.5" bay.
Replace the optical drive with a hard drive.
Despite such limitations, there is a solution: OptiBay from MCE. OptiBay is a snap-in that contains an adapter that allows you to connect a hard drive instead of an optical drive.
Obviously, since the laptop uses an optical drive of PATA format, then the hard disk should have the same interface. There are two versions of OptiBay for MacBook and MacBook Pro: for computers with thin optical drives (thickness 12.5 mm) and for computers with ultra-thin drives (9.5 mm). OptiBay can be used on any laptop, but you need some tools, including a tray. OptiBay costs $ 99, but you can order a snap-in with a hard drive or an external optical drive.

The choice of components: hard disk.
We have an adapter, it remains to choose a hard drive and an SSD-drive. As a hard disk, we need a PATA-model with a decent capacity (at least, 120 GB). The speed does not matter much, since the disk will be used only for data storage, and all programs will be on the SSD-drive. We chose the Samsung HM160 (5 400 rpm, 160 GB). Note that the latest 2.5 "hard drives are not released in PATA, but only in SATA-format, which limits the available capacity (there are 250-GB PATA models, but they are rarely found).

Choice of components: SSD-drive.
The second problem was the choice of SSD-drive. First, it must be a SATA drive, because the original hard disk of the laptop uses this interface. Secondly, its capacity should be at least 32 GB, so you can easily use the latest versions of operating systems, such as Mac OS X Leopard or Windows Vista, and at the same time install all the necessary applications on the SSD-drive. We chose the 32-GB Mtron MOBI 3000. This high-speed SSD (based on the specifications, the read speed is 100 MB / s and the write speed is 80 MB / s) uses the SATA interface and is today one of the most famous models of solid-state drives.

The first step was to change the hard drive. Although most laptops to the hard drive get quite easily (usually just need to unscrew a couple of screws), the MacBook Pro has to be almost completely disassembled. You can see from the illustrations below that this is not so easy.
In the case of conventional laptops, for example, with the Samsung R60, to get to the hard drive, you just need to unscrew the two screws and lift the cover, as shown in the photo below.

But in the case of the Apple laptop, you will have to disassemble almost the entire case. Below are illustrations of all the steps for installing an SSD drive in the MacBook Pro.

Note that, despite the high cost of an SSD (about $ 700-800), it's pretty badly done. We had, for example, literally cut the holes to use the original MacBook Pro screws (even if they are quite standard).
Installing the second hard disk.
The next step is to install the second hard disk. In a 17 "laptop, it's easy: open the lid and install the hard drive, other models also have the option of installing a hard drive to the place of the optical drive if the manufacturer provides the compartment, as Dell did.
As we said, we had to buy an OptiBay adapter. The following shows how we installed OptiBay in our test notebook MacBook Pro.

In a standard laptop.
In the case of a standard notebook, you can either buy a hard drive bay (for example, Lenovo and Dell provide this option), or you'll need to use a snap-in like OptiBay. The model we tested is for Mac computers that use an optical drive with slotted disk loading, without a tray, but it can easily be adapted. Some manufacturers, for example, Sony, provide this option directly. The Vaio TZ (ultraportable notebook) can hold a 2.5 "hard drive in addition to the 1.8" drive (instead of an optical drive).

Comparison of the performance of SSD-drive and hard disk.
Although this is not the main purpose of this article, we can not bypass the theme of SSD performance.
As a test system, there was a 15 "MacBook Pro laptop (June 2007), a 2.2 GHz Core 2 Duo processor (4 MB L2 cache, 800 MHz bus), 4 GB DDR2-667, nVidia GeForce 8600M GT 128 MB;
The storage is naturally different: Fujitsu hard drive (2.5 ", 160 GB, 5,400 rpm) and SSD-drive Mtron (2.5", 32 GB).
OS boot time.
MacBook Pro with a solid-state drive was much faster than with a hard drive, and slightly faster than a MacBook Air with SSD.
Download time of the file.
Running Adobe Photoshop CS3 on laptops with SSDs is three times faster. A 500 MB image (in TIFF format) opens also much faster, although the difference is not so huge. Note that the MacBook Pro is slightly faster than the MacBook Air, although memory and processor play a role.
Microsoft Word 2008.
Running Microsoft Word 2008, which is a very slow application, again benefits from using SSDs: boot time is three times faster. However, even with SSD, Word 2008 runs very slowly (especially compared to the Windows version).
For the last test, we tried to unzip the archive (.rar) containing several large files (about 500 MB) and a large number of small files (less than 1 MB). With this test, we wanted to show one of the weak points of solid-state drives: writing small files. SSD-drive in the MacBook Air, which is average in speed, was much slower than Mtron in the MacBook Pro. However, even in this test, specially designed to challenge the SSD, Mtron proved to be better than the hard drive.
It is very easy to get a simultaneous work of hard disk and SSD-drive, if you have the correct model of the laptop. For everyone else, including us, this is also possible, even if it takes a while. For this purpose, a laptop designed on the principle of flexibility and using removable peripherals (for example, models Dell Pro, Lenovo, Toshiba, etc.) is more suitable than computers of a consumer level (or Mac, as in our case).
Installation of SSD-drive is simple, if there is a special removable HDD-compartment, as in Lenovo. Click on the image to enlarge.
As for the SSD itself, its performance is impressive, and it's a pleasure to use it. But does the convenience of the user justify the high cost of an SSD? You decide. If you have money, then the answer is, of course, yes. But if the money is a problem, then we strongly recommend to wait. Solid-state drives are a fresh solution (for the general mass of consumers), and they are constantly evolving. Therefore, we should expect a gradual fall in prices.
